EP3606852B1 - Method and device for exactly positioning and processing textiles - Google Patents

Description

The invention relates to a method and a device for the exact positioning and processing of textiles or fittings.

Methods and corresponding devices are known in the prior art, in which textiles, such as textile webs or textile fittings, are (pre)aligned manually or automatically and, aligned accordingly, are fed, for example, to a processing step or a transport device of the device. The transport device transports the textiles through the device to various processing stations.

With such methods and the corresponding devices, both textile fittings and fittings made of any material, which can be processed in the same way as a textile material, are processed. This includes, for example, fitting pieces made of paper or plastic.

For example, the automatic (pre)alignment of a textile web, which is correctly aligned before processing, such as cutting the web into fitting pieces, is known.

The textile web is aligned mechanically, for example by mechanically drawing the marginal edge or pile edge of the textile to a segmented straightening bar. The straightening bar specifies the exact alignment.

In order to be able to carry out such a mechanical alignment, the textile webs must have an edge that can be caught by the straightening bar in order to be able to pull the web into a desired position. This results in the disadvantage that this type of alignment without a border or pile edge, for example according to patterns or according to a thread or stitch course, is not possible. In addition, the textile must be endless, as is the case with textile webs. This form of alignment is not possible with textile fittings.

After the correct alignment of the textile web, it is possible to cut the fitting pieces exactly. The fitting pieces are then processed further, for example hemmed, folded and/or sewn, with each fitting piece being transferred automatically or manually to a device section that processes the fitting piece further.

In the case of an automatic transfer, the fittings are transferred by appropriate transfer and/or transport means to a station in which, for example, further processing can take place or from which the fitting is transported further. Deviations from the exact alignment of the fitting piece that resulted from cutting the (pre)aligned textile are adopted. Also in the transfer process to the station can Fitting pieces in the device slip so that they are no longer precisely aligned. It follows from this that an exact further processing of the fitting is not possible and a product of inferior quality is created.

In the case of a manual transfer, a worker takes the fitted piece from the upstream processing station or a depot and feeds it to the station manually (pre)aligned, whereby the manual alignment and positioning can be carried out by the worker aligning the textile by eye or with mechanical aids and put it into the device. Inaccuracies in alignment and positioning can occur with new, unskilled workers, but also with inattentiveness of experienced workers, with the disadvantage that the textile cannot be processed in an exactly aligned manner. These inaccuracies mean that the textile intermediate or end product, which is created during processing, is of inferior quality and is therefore unacceptable.

Even if the fitting is handed over correctly (pre)aligned manually or automatically, deviations from the exact alignment can occur when the fitting is transported to the processing station. For example, belt drives are used as a means of transport, which transport the fitting piece through the device via a transport plate, which, particularly in the case of particularly thick and/or flexible textiles, can result in the piece fitting in the Transport device has slipped and correct alignment cannot be ensured during further processing.

The object of the invention is to create a method and a device with which it is ensured that the fitting piece fed to the processing station is precisely aligned and a particularly high-quality product can be manufactured, with individual alignment also of textiles at the same time or similar fitting pieces without edges and/or pile edges is possible.

To solve this problem, a non-claimed method is proposed.

The fitting piece can be removed manually by a worker, for example from an upstream device section or from a depot. Before it is fed into the device, in particular the station of the device, a manual (pre)alignment or positioning of the fitting takes place, with the worker then manually feeding the fitting to the device or the station.

Alternatively, the automatic (pre)alignment or positioning of the fitting is possible, for example in an upstream device section in which the fitting is (pre)aligned or positioned and then automatically fed to the device or station.

The station can be, for example, a transport station that transports the fitting through the device or performs any other task.

After the fitting has been fed in, its alignment and/or positioning is checked and, if necessary, a correction is made.

The check is preferably carried out without contact, e.g. by sensory detection of markings on the adapter. The markings are preferably arranged on the surface of the adapter, for example in the form of a pattern, or in the fabric of a textile, for example in the form of the course of the thread or of stitches, seams or similar fabric markings. Markings can also be formed by differences in the fabric, for example in the form of patterns formed by different pile heights.

The markings are preferably detected by sensors.

The sensory detection can take place by means of the human eye or by appropriate devices. The recorded marking course is compared with a predetermined target marking course. This is also done optionally by humans or by a suitable processing device, for example a data processing device.

If detection and comparison are made by the human eye of a worker, the target marking course can, for example, on the Transport document be shown or formed by the transport document over which the adapter is transported. The worker recognizes a deviation of the fitting piece course from the desired course and determines a correction value. The worker can determine the correction value on the basis of empirical values and transmit it to a control element coupled to a correction station, for example by manual input, so that a manual correction is carried out in accordance with the correction value.

If a deviation is detected by devices, the recorded marking course is transmitted to a processing station, for example, which then carries out a comparison with the target marking course, with the target marking course preferably being stored in a memory of the processing device and being available for comparison with the actual marking course. In the event of deviations, the processing device calculates a correction specification, which is transmitted directly to a suitable recipient of the correction station, so that the correction station automatically corrects the alignment.

Alternatively, the correction specification calculated can also be displayed on a display panel such as a monitor, so that a worker can read this specification and enter it manually into an operating element coupled to the correction station.

The correction device then performs a Correction according to the correction value or according to the correction specification, so that the marking courses are at least approximately matched. The correction can be made, for example, by transmitting the correction value or the correction specification to a control unit of a suitable mechanical component, with the control unit controlling the mechanical component and the latter carrying out the correction by appropriate mechanical action on the fitting and bringing the fitting into correct alignment.

Such a subsequent correction of the course of the marking and thus of the fitting piece enables the textile to be positioned exactly in the device, so that the textile can be processed precisely in the processing station and a particularly high-quality product is produced.

The preferably non-contact check also enables the alignment of edgeless fitted pieces, so that an individual and precise alignment and positioning can take place solely on the basis of patterns or thread courses or similar textile markings.

After the processing, a new check and correction can take place if, for example, further processing steps follow, in which the fitting piece has to be precisely aligned, it being possible for individual or multiple method steps to be repeated.

The fitting pieces are transported through the device by a transport device. The fittings can shift in the device during transport, so that a correction during transport is advantageous in order to precisely align the fitting again in front of a further processing station. The method steps are carried out during the continuous transport of the fitting through the device in order to be able to carry out the method economically. Very high speeds of 20m per minute and more can be achieved.

According to the invention, the object is achieved by the method according to claim 1.

The fitting piece can be removed manually by a worker, for example from an upstream device section or from a depot, and fed manually to the device. Before being fed into the device, in particular the station of the device, a manual (pre)alignment or positioning of the fitting takes place.

Alternatively, automatic (pre)alignment or positioning of the fitting and subsequent automatic feeding to the device or station is also possible.

The station can be, for example, a transport station that transports the fitting through the device or performs any other task.

After the first fitting has been fed in, it is processed in the processing station. Its alignment and/or positioning is then checked. If deviations from the course of the desired marking are determined during the check, correction values or correction specifications are determined, which are transmitted to a correction station arranged in front of the processing station. The fitting pieces subsequently transported through the device are then aligned before being fed to the processing station according to the correction values or correction specifications. As a result, the subsequent fittings for the processing step are correctly aligned and high-quality products can be manufactured.

The check is preferably carried out without contact, e.g. by sensory detection of markings on the adapter. The markings are preferably arranged on the surface of the adapter, for example in the form of a pattern, or in the fabric of a textile, for example in the form of the course of the thread or of stitches, seams or similar fabric markings. Markings can also be formed by differences in the fabric, for example in the form of patterns formed by different pile heights.

The markings are preferably detected by sensors.

The sensory detection can take place by means of the human eye or by appropriate devices. The recorded marking course is compared with a predetermined target marking course. this happens also optionally by humans or by a suitable processing device, for example a data processing device.

During the detection and comparison by the human eye of a worker, the worker recognizes a deviation in the course of the fitting piece from the desired course and determines a correction value. The worker can determine the correction value on the basis of empirical values and, for example, transmit it to a control element coupled to a correction station by manual input, so that a manual correction is carried out according to the correction value.

Alternatively, the recording and the comparison can be recorded by devices, with the recorded marking course being transmitted to a processing station, for example, which then carries out a comparison with the target marking course. The target marking course is preferably stored in a memory of the processing device and is available for comparison with the actual marking course. In the event of deviations, the processing device calculates a correction specification, which is transmitted directly to a suitable receiver in the correction station, so that the correction station can automatically correct the alignment of subsequent fitting pieces.

Alternatively, the correction specification calculated can also be displayed on a display panel such as a monitor, so that a worker can read this specification and enter it manually into an operating element coupled to the correction station.

The correction device performs a correction according to the correction value or according to the correction specification, so that the marking curves are at least approximately matched.

The correction can be made, for example, by transmitting the correction value or the correction specification to a control unit of a suitable mechanical component, with the control unit controlling the mechanical component and the latter carrying out the correction by appropriate mechanical action on the fitting and bringing the fitting into correct alignment.

Such a subsequent correction of the course of the marking and thus of the subsequent fitting pieces enables the textile to be positioned exactly in the device, so that the subsequent textiles can be processed precisely in the processing station and a particularly high-quality product is produced.

The preferably non-contact check also enables the alignment of edgeless fitted pieces, so that an individual and precise alignment and positioning can take place solely on the basis of patterns or thread courses or similar textile markings.

After processing, a new check and correction can take place, with the repetition of individual or multiple process steps being possible.

It is preferably provided that the process steps during the continuous or discontinuous transport of the fitting take place.

The fitting pieces are transported through the device by a transport device. The fittings can shift in the device during transport, so that a correction during transport is advantageous in order to precisely align the fitting again in front of a further processing station. The method steps can preferably be carried out during the continuous transport of the fitting through the device in order to be able to carry out the method economically. Very high speeds of 20m per minute and more can be achieved. If necessary, however, discontinuous transport can also take place.

Provision is preferably made for the correction to be carried out immediately before the supply for processing and implementation of the processing step.

This ensures that the fitting piece is fed to the processing station in an exact alignment and is processed there, and a product of particularly good quality can be manufactured.

It is preferably provided that a sensor device with at least one sensor or a camera detects the markings on the fitting and that the sensor device or the camera communicates with a computer which actually detects the Matches the marking course with the target marking course stored in a memory of the computer and, in the event of deviations, provides the correction specification for automatic or manual correction.

The fitting is transported past the sensor device or the camera using transport means, with at least one sensor or camera capturing a pattern or a thread course of the fitting.

Alternatively, the sensor device or the camera can be transported past the adapter. The sensor device or the camera communicates with a computer and transmits the recorded data to it. The computer is connected to a memory and can access the stored data, with at least one desired marking process being stored in the memory, with which the computer compares the actual marking process. In the event of deviations, the computer creates a corresponding correction specification and makes this available for the correction to be carried out. The correction can take place automatically in that the correction specification is transmitted to the correction station as a corresponding control signal.

Alternatively, the correction can be done manually, with the correction default being displayed and read on a display panel, such as a monitor, and then being entered into an operating element that communicates with the correction station.

Provision is preferably made for the sensor device or the camera to record the actual path of the deviation and the direction of the deviation.

This will create the exact marker history. With regard to the direction, it is detected, for example, whether the deviation is on the left or right side transverse to the transport direction. The path is also precisely recorded, i.e. to what extent there is a deviation. The path can be determined in mm, for example. These recordings are compared with the course of the target marking so that an exact correction specification can be created in the relevant dimensions.

It is preferably provided that the sensor detects the distance from the markings on the surface of the adapter.

As a result, deviations from the course of the desired marking due to the course, for example, of the pile height or other elevations on the surface of the adapter can be detected.

It is preferably provided that the correction values and, if applicable, the correction specification are entered manually into an operating element and the alignment is corrected according to the input.

A worker can enter the determined correction values into the control element and bring about the correction of the alignment.

If the curves have been compared by a processing device and a correction specification has been created, this correction specification can preferably be obtained from a display panel be read and entered into the control element.

The operating element is preferably coupled to a correction station via a control unit, with the control unit controlling the correction station in accordance with the input into the operating element.

Provision is preferably made for deviations and/or the correction specification to be displayed on a display panel.

The correction specification, for example in the form of a numerical value or a comparable indication, is displayed on the display board and can be read there. If necessary, this value is used for manual correction by a worker entering the value into a control element which communicates with the correction station. Alternatively or additionally, the deviations from which a correction value can be determined can also be displayed.

Alternatively or additionally, it can preferably be provided that the correction specification is transmitted directly to a correction station, which carries out the correction automatically in accordance with the correction specification.

This means that no human intervention is necessary and the alignment of the fitting is corrected fully automatically. A control element and/or a display panel can also be present for safety in the event of automatic failures or for individual adjustment.

Provision is preferably made for the correction to take place transversely to the transport direction in both directions.

The fittings can slip in both directions transverse to the direction of transport, so correction in both directions is required to achieve exact alignment.

A special embodiment of the invention also relates to a correction, which is a method for aligning a surface area or an edge area of a flexible piece of material or a textile piece, the piece of material being transported at least close to a surface area or an edge area by means of a transport device in a conveying direction and thereby is pressed against a support part of the transport device by means of a driven transport means of the transport device and is transported along the support part.

Methods and devices for aligning edge regions of flexible pieces of material, for example pieces of textile material, are known in the prior art.

The term “flexible pieces of material” is not only to be understood as meaning pieces of textile material, but also pieces of material made of plastic, paper or similar materials.

In the prior art devices are known in which textile material webs at their Longitudinal edges are aligned and hemmed. After hemming, these panels are aligned and divided into patches of generally rectangular shape. These fitting pieces are then re-aligned with their edges not yet trimmed or folded over and transported by an appropriate transport device, the alignment being carried out for the purpose of enabling subsequent seaming and sewing of the edge area without a defective appearance occurring. Improper appearance occurs when the peripheral edge of the fitting is not properly aligned. Alignment devices and alignment methods are known in the prior art, in which a pile edge present on the fitting piece or piece of material, which rises above the plane of the piece of material, is used as an alignment aid. Mechanical alignment means can be supported on this pile edge and also align the pile edge relative to the corresponding subsequent devices which are required, for example, for hem formation and for sewing. However, if such a pile edge is missing, alignment is usually not possible or only possible with considerable difficulty.

It is also not sufficient, for example, to align the foremost end of an edge region of a piece of material and then to transport this piece of material through appropriate devices, because at the beginning of the Piece of material formed alignment position does not continue over the piece of material, because the piece of material is flexible and during further transport by appropriate facilities at the beginning of the existing alignment is lost, so that a high-quality edge formation is not possible.

This occurs in particular with flexible pieces of material that have already been provided with longitudinal seams beforehand, if the piece of material has not yet been separated from a web of material, and which are then to be provided with corresponding transverse seams by changing the alignment position when the pieces of material have been separated from the web of material significant problem to ensure high quality and correct alignment in the edge area. However, such an alignment is a prerequisite for the further processing of the corresponding fitting piece or the like, because after the alignment, a hem may have to be formed by machine and the hem sewn by machine. Only after this work has been completed is the corresponding fitting piece completed. Errors in prior alignment will result in the mating being finished with inferior quality and is therefore unacceptable.

To correctly design a surface area or edge area of a piece of material in the form of a textile fitting piece in a simple manner To be able to ensure further training is suggested.

In the conventional procedure, the piece of material is first transported in a conveying direction near an edge region by means of a transport device. The transport device can consist, for example, of a circulating transport belt, which can also be operated via other work stations of the production device. When used as intended, the transport belt is pressed against a support part, for example a support plate, and transported along the support part. The support plate forms the counter bearing, so that the edge area of the piece of material is held between the transport means (transport belt) and the support part and is transported along the support part in the transport direction.

In a special embodiment of the solution according to the invention, it is provided that if the orientation of the piece of material deviates from a target orientation of the piece of material closer to the transport means, the differently oriented area or edge area of the piece of material is rotated transversely to the conveying direction by a tensile force acting parallel to the plane spanned by the piece of material a corresponding amount is moved away from the means of transport, so that the deviating orientation of the piece of material is converted into the desired orientation.

A piece of material that has slipped in the transport device in the direction of the transport means can be pulled transversely to the transport direction by the predominantly horizontal force and brought into a correct alignment.

As an alternative to a special embodiment of the solution according to the invention, it is provided that the edge region of the piece of material is fixed in at least one second transport device that is spaced apart from the transport device and forms a free space with it and is transported concurrently and closer if the alignment of the piece of material deviates from a target orientation towards the first means of transport at least one actuator acts with a compressive force on the area of the piece of textile spanning the free space and the piece of textile is thus moved away from the first means of transport by a corresponding amount transversely to the conveying direction and transversely to the first means of transport, so that the deviating alignment of the piece of material in the Target alignment is transferred.

During transport through the device, the edge area of the piece of material is fixed in the second transport device. The second transport device is preferably concurrent with the first transport device, so that the piece of material is transported evenly through the device. There is a free space between the first and the second transport device provided which is spanned by the piece of material. As soon as a deviation of the piece of material from the target alignment is detected, an actuator acts with a compressive force on this area, so that the piece of material is only moved transversely to the first transport device until it is transferred to the target alignment.

As an alternative to a special embodiment of the solution according to the invention, it is provided that the transport device or a machine part assigned to the transport device is equipped with an alignment edge or the support part forms an alignment edge that is set in an alignment position such that when the alignment of the piece of material deviates from a target alignment If the piece of material is closer to the means of transport, the differently aligned area or edge area of the piece of material is pulled over the alignment edge and is thus moved away from the means of transport transversely to the conveying direction and transversely to the means of transport by a corresponding amount, so that the deviating alignment of the piece of material is converted into the desired alignment.

According to a special embodiment of the invention, an alignment edge is provided at a suitable position of the machine frame, the transport device or other parts of the overall device, which is used for the purpose of aligning the piece of material. The alignment edge can be stable be edge. However, an alignment edge in the form of a rod, a flexible tensioned wire or the like can also be provided.

The support part itself can also form an alignment edge. The respective alignment edge can be set in a position that is suitable for the intended purpose. If the piece of material is in an orientation that deviates from the target orientation, the piece of material can be pulled over the alignment edge and thus moved transversely to the conveying direction and transversely to the transport means, so that the deviating orientation of the piece of material is converted into the target orientation.

The term transverse is not to be understood in the sense of right angles, but it is sufficient, for example, if the pulling movement is directed at an angle, so that part of the pulling force component is directed horizontally and another part of the pulling force component is directed vertically. In any case, a sufficient amount of tensile force must be exerted on the piece of material in order to move it to the desired extent.

It is preferably provided that the piece of material is transported at least close to a surface area or an edge area by means of a transport device in a conveying direction parallel to the edge area. It is preferably provided that the support part has at least one recess or an alignment edge, so that if the alignment of the piece of material deviates from a target alignment of the piece of material closer to the transport means, the differently aligned area or edge area of the piece of material extends over the alignment edge running with respect to the conveying direction or over an alignment edge of the recess that runs with respect to the conveying direction and is adjacent to the transport means is pulled and is thus moved away from the transport means by a corresponding amount transversely to the conveying direction and transversely to the transport means, so that the deviating alignment of the piece of material is converted into the exact target alignment.

In at least one of the protruding areas, preferably in both protruding areas, a recess or an edge is provided, which runs parallel to the conveying direction. The piece of material lies, for example, above the corresponding recess or the edge. The user can determine the orientation of the edge region of the piece of material and act on the piece of material if the orientation of the piece of material deviates from an exact desired orientation of the piece of material. If the edge area of the piece of material deviates from the exact desired alignment and runs closer to the means of transport, then the area or edge area that is aligned differently becomes of the piece of material is pulled over the edge running parallel to the conveying direction or over an edge of the recess running parallel to the conveying direction and adjacent to the means of transport, namely transversely to the direction of conveyance and transversely to the means of transport and thus moved (pulled) away from the means of transport by a corresponding amount, so that the deviating alignment of the piece of material is transferred into the exact desired alignment. As soon as the desired alignment has taken place, the edge region of the piece of material is no longer acted on by means of a tensile force, but this is transported further solely with the means of transport. Preferably, such a configuration and alignment is provided on both sides to the right and left of the means of transport, so that a compensation is achieved by corresponding tensile forces acting on the edge region on the one hand and by corresponding tensile forces acting on the piece of material on the other side, resulting in a exact target alignment of the piece of material.

Provision is preferably made for the alignment edge to be aligned parallel to the conveying direction.

Such an orientation is not absolutely necessary, but is advantageous for carrying out the method.

Even if the alignment is not exactly parallel the alignment is possible because a compensation can take place through the application of appropriate force in order to ultimately ensure the desired alignment.

Provision is also preferably made for the tension to be applied by the action of force directed at least approximately vertically to the material strip.

This is advantageous for an exact target alignment of the piece of material.

In particular, it is provided that during the application of the force or the tensile force, the means applying the force or tensile force is moved in the conveying direction at an angle to the conveying direction, preferably parallel to the conveying direction of the transport means, or additionally applies a movement component in the conveying direction to the material strip, preferably parallel to the conveying direction.

The result of this is that the alignment is not only carried out selectively in a narrow area, but over a larger area which runs essentially parallel to the conveying direction and the alignment can also be carried out discontinuously or continuously during the conveying process.

It is particularly preferably provided that the Movement of the means in the conveying direction or the movement component is adapted to the transport speed of the transport means in order to avoid wrinkling of the strip of material.

Provision can also be made for the piece of material to have a sensory or optically detectable edge or edge or a marking, line or step running parallel to the conveying direction, whose alignment deviating from the target alignment is detected by a means executing or monitoring the method and by activating a technical means is used for the exact target alignment of the piece of material.

In terms of device, the object stated at the outset is achieved by a device according to claim 21 .

The fitting is fed to the station automatically, preferably by an upstream device section, or manually by a worker. A transport device is connected to the station or integrated into it, it being possible for the station itself to be a transport device for receiving the fitting or, if necessary, for the transport device to be arranged starting in front of the station so that fittings can be transported from the station or through the Station can be transported through to the subsequent transport device. With the transport device, the fittings are transported through the device into the processing station.

The checking station and the correction station carry out a post-correction of the fittings, so that the alignment of a fitting that has been displaced from the target position during transfer or transport by the device is corrected before it is fed to the processing station in which the fitting is processed. This ensures a particularly good quality of the intermediate or end product.

The checking station can be arranged in front of the correction station, so that a check and a subsequent correction are carried out first.

Alternatively or additionally, a checking station can be arranged downstream of the processing station, which checks the alignment of the processed fitting and, in the event of deviations, creates a correction specification or a correction value for the following fittings.

The checking station enables contactless detection of the course of the marking, with the preferably sensory detection being carried out with the human eye or with corresponding devices. Although the alignment of the fitting pieces can be checked at a marginal edge or textile fitting pieces at a pile edge, since the edge can be detected by sensors, such an edge is not absolutely necessary, since detection is also possible using patterns or similar markings.

In the checking station, the previously recorded marking course is compared with the target marking course and a correction value or a correction specification is determined.

A correction value is provided during the check by the person who carries out the comparison of the marking course with the target marking course and, for example, on the basis of empirical values, determines which correction value is to be used.

Alternatively, a comparison is carried out using appropriate technical means for data processing and a correction specification is created.

The alignment is then corrected by the correction station, which uses the correction values or the correction specification to carry out an exact alignment of the fitting.

An intermediate or end product of excellent quality is produced in the processing station. The processing station can be a fixing device in which the fitting pieces are hemmed or sewn, for example. However, any other processing step can also be carried out.

It is preferably provided that the checking station has a detection device for sensory detection of the actual marking course and a processing device coupled thereto for comparing the detected marking course with the target marking course preferably stored in an electronic memory and for evaluating deviations and, if necessary, providing a correction specification.

The course of the marking recorded with the detection device is transmitted to the processing device, which carries out a comparison with the desired course of the marking. For this purpose, the processing device is connected to a memory on which at least one target marking profile is stored, the processing device accessing the data in the memory and comparing the target marking profile with the marking profile.

In the event of deviations in the curves, the processing device calculates a correction specification and makes this available. The correction specification is then transmitted to a display board and displayed. Alternatively, the correction specification can be provided as a corresponding control signal and transmitted directly to a control unit of the correction station.

Provision is preferably made for the detection device to have a camera or a sensor device with at least one sensor.

Contactless detection of the course of the marking is possible by means of the sensor device or the camera.

It is preferably provided that the sensor is an optical sensor or a sensor that carries out distance measurements.

Optical sensors can be used to optically detect a marking path. For example, colors or patterns can be detected.

However, a marking progression in the form of different pile heights can also be detected on the surface of the adapter. These can also be detected optically. Alternatively, these markings can also be detected by distance measurements. For this purpose, a sensor that carries out distance measurements is provided, which detects the distance to the tips of the pile.

It is preferably provided that the sensor is an optical sensor and a light source is arranged opposite the sensor device or the camera and that the adapter is arranged between the sensor device or the camera and the light source during transport through the device.

A light source is arranged opposite the sensor device or the camera, which illuminates the fitting so that the sensor or the camera can better detect markings of fittings that can be illuminated through.

Provision is preferably made for the processing device to have a computer with a memory and at least one desired marking course stored thereon for comparison with the actual marking course.

Different target marking courses can be stored on the computer or new target marking courses can be stored later for new ones production lines are programmed. These can then be selected depending on the production line and are available for comparison with a corresponding recorded marking history.

Provision is preferably made for the correction station to have a control unit which is coupled to an operating element for inputting correction values and correction specifications, if applicable, and is controlled by this.

A correction value determined by the worker or a correction specification calculated by the processing device can be entered manually into the operating element, which transmits a corresponding actuating signal to the control device. The correction station corrects the alignment according to the input.

The correction can be made, for example, by a suitable mechanical component, with the control unit controlling the mechanical component according to the correction value or the correction specification, so that it carries out the correction by means of a corresponding mechanical action on the fitting piece and brings the fitting piece into correct alignment.

Provision is preferably made for the device to have a display panel which is coupled to the checking station and on which the correction specification provided by the checking station is displayed.

The display panel can be a monitor, for example, on which the correction specification is displayed and can be read in order to be able to enter them into a control element. This allows manual correction of the alignment of the fitting.

Alternatively or additionally, it can preferably be provided that the checking station communicates directly with the correction station and the correction specification is introduced directly into a control unit of the correction station by means of signals generated by a computer in the checking station.

As a result, an automatic correction is made according to the correction specification, without human intervention.

Furthermore, a special embodiment of the invention relates to a correction station, which is a device for aligning a surface area or an edge area of a flexible piece of material or a textile piece, consisting of a transport device with a machine frame for pieces of material with at least one driven transport means or a transport belt, and a Support part for the transport means, with an area located close to the surface area or an edge area of the piece of material being transportable in a conveying direction.

In order to be able to ensure a correct formation of a surface area or an edge area of a piece of material in the form of a textile fitting in a simple manner, a further development is proposed.

In terms of the device, it is proposed that the device has at least one adjusting means, which can be moved from a basic position, in which its functional components lie outside the plane spanned by the piece of material, into a working position, in which it is at least approximately flush with the plane and holds the piece of material in a clamped manner, with the adjusting means being moved in the working position during the adjustment movement transversely to the transport means and transversely to the conveying direction, specifically taking with it the area of the piece of material located next to the transport means.

The adjusting means is moved from an open basic position into a working position in which the piece of material is held in a clamped manner. The adjusting means is then adjusted transversely to the conveying direction, taking the area of the piece of material with it and acting on it with a force until the piece of material is transferred into the desired orientation.

It is preferably provided that the device has an adjusting means on both sides of the transport device.

This configuration enables alignment on both sides to the right and left of the means of transport, so that compensation is achieved by corresponding forces acting on the edge region on the one hand and by corresponding forces acting on the piece of material on the other side, resulting in an exact Target alignment of the piece of material leads.

In terms of device, it is alternatively proposed that the device has at least one second transport device arranged at a distance from the transport device with a second transport device, with which the edge region of the piece of material can be fixed and transported, with a free space being arranged between the second transport device and the first transport device, which is spanned by a region of the piece of material, has at least one adjusting means, which is fixed to the frame and which can be moved from a basic position, in which its functional components lie outside the plane spanned by the piece of material, into a working position, in which these Plane penetrates, wherein the adjusting means is moved during the adjustment movement into the free space, taking with it the area of the piece of material spanning the free space and the piece of material relative to the first transport means transversely to the conveying direction and transversely to the plane ne is moved, it being preferably provided that the second transport means is a pair of belts or a transport belt with a counter bearing.

The piece of material is held by the first and the second transport device and, with the material region between the held edge regions or material regions, spans a free space which is formed between the transport devices.

If the piece of material deviates from the target alignment, an adjusting agent is used by one The basic position can be adjusted or shifted into a working position in which it penetrates the plane spanned by the piece of material, taking with it the area of the piece of material spanning the free space. The first transport device allows the piece of material to move while the piece of material is fixed in the second transport device, so that the piece of material is moved transversely to the conveying direction and transversely to the plane by the pressure acting on the area relative to the first transport means and is transferred to the desired orientation.

It is preferably provided that the device has second transport devices and adjusting means arranged on both sides of the transport device.

This configuration enables alignment on both sides to the right and left of the means of transport, so that a balance is achieved by corresponding forces acting on the edge area on the one hand and by corresponding forces acting on the piece of material on the other side, which leads to an exact target alignment of the piece of material leads.

In terms of device, it is alternatively proposed that the machine frame or a separate device frame is equipped with an alignment edge or the support part has an alignment edge that is set or adjustable in the alignment position, that at least one adjusting means is fixed to the frame which can be adjusted from a basic position, in which its functional components lie outside the plane spanned by the piece of material, preferably above this plane, into a working position in which it extends through this plane, with the adjusting means during the adjustment movement being transverse to the conveying direction and is moved transversely to the plane past the alignment edge, taking with it the area of the piece of material located next to the transport means.

The appropriate arrangement of an alignment edge, which can be formed by a strip of material or else by a wire or the like, provides the necessary means to achieve alignment. The support part itself can also have the alignment edge. If positioning deviates from the desired orientation, the adjusting means can be used to set a working position, the adjusting means then entraining the corresponding area of the piece of material and causing the piece of material to be aligned.

It can preferably be provided that an area of the piece of material located near a surface area or edge area is clamped or can be clamped between the support part and the transport means.

It can also preferably be provided that the surface area or the edge area in one Conveying direction can be transported parallel to the edge area.

In particular, it can preferably be provided that the support part protrudes beyond the transport means on both sides transversely to the conveying direction and in at least one of the two protruding areas has a recess with a peripheral edge aligned with respect to the conveying direction, preferably parallel to the conveying direction, which is adjacent to the transport means or forms a marginal edge which is preferably directed parallel to the conveying direction, the marginal edge in each case being the alignment edge.

Provision is particularly preferably made for a movable support to be arranged, held or fixed on the machine frame or on the support part or next to the support part or below the support plane of the support part for the piece of material, against which at least part of the adjusting means is placed when adjusting into the working position, with the interposition of a portion of the piece of material.

As a result, the entrainment of the piece of material is promoted when the actuating means is activated, because the actuating means is given a counter bearing by the movable support and the strip of material is arranged between the actuating means and the movable support.

In addition, it is preferred that the length of the adjustment path of the actuating means from the Basic position is adjustable in the working position for the purpose of correct alignment of the edge area of the piece of material.

Provision can also preferably be made for the support to be attached to the machine frame on the support part in a resiliently pivoting manner.

A possible variant is seen in the fact that the adjusting means is designed as a skid, roller or stamp at its free end facing the piece of material.

A preferred variant is seen in the fact that the adjusting means is a driven roller or roller or a belt drive with a driven and at least one free-running roller or only with free-running rollers.

In this case, it is particularly preferable for a motorized rotary drive to be arranged fixed to the frame as the drive for the actuating means, which is connected via a coupling means, in particular a drive belt or a gear wheel or friction gear, to a drive shaft which is mounted in a mounting block and fixed to the frame, with the Adjusting means is held pivotably about the drive shaft.

It is also preferably provided that the adjusting means can be adjusted by means of an adjusting drive held on the frame.

In this case, it can preferably be provided that the actuating means is held pivotably on a frame part and can be adjusted into the basic position or a working position by means of the actuating drive.

Provision is preferably made for the device to have a support part with protruding areas, optionally a recess, and an adjusting means on both sides next to the transport device.

In order to improve the guidance of the piece of material, it can be provided that an inclined guide part is arranged following the recess in the conveying direction, which preferably transitions steplessly into the protruding area.

A possible variant is seen in the fact that the adjusting means can be adjusted intermittently from the basic position to the working position and back.

It is preferably provided that the actuating means has a revolving actuator, in particular a belt drive, which is driven in revolving fashion at least at the start of the transition from the basic position to the working position and continuously during the working position.

In addition, it is preferably provided that the actuator is aligned in the same direction as the conveying direction, in particular in at a small angle thereto or preferably parallel thereto, is formed circumferentially.

It is preferably provided that the device has a detection means for optical or sensory detection, in particular of a deviating alignment of the piece of material from the desired alignment, which communicates with an actuator for adjusting the actuating means from the basic position to the working position.

If the detection means detects a deviation in the alignment of the piece of material, a corresponding signal is sent to the actuating drive of the actuating means and the actuating means is moved into the working position, so that the piece of material is aligned in the desired alignment.

figure 1 shows schematically a method for the exact positioning and processing of textiles or the like, in particular fittings 1, with the following method steps:

• Mechanical or manual feeding 3 of a (pre)aligned and/or positioned fitting 1 to a device 2 or a station 9 of the device 2,
• Checking 4 the alignment and/or positioning of the fitting, with markings on the fitting, which are preferably arranged on the surface of the fitting or in the fabric of the fitting, preferably being detected by sensors and the actual marking course being compared with a target marking course
• Determination 5 of correction values or correction specifications and, if necessary, provision of a correction specification if the actual marking course deviates from the target marking course, and
• Transmission 6 of the correction value or the correction specification to a correction station 12,
• manual or automatic correction 7 of the alignment of the adapter 1 by means of the correction station 12 in accordance with the correction values or in accordance with the correction specification, with the recorded marking course being brought into line with the target marking course and/or
• Feeding 8 of the fitting 1 in a transport direction 23 to a processing station 13 processing the fitting 1, preferably a fixing device, in which a processing step is carried out,
• if necessary repetition of individual or several process steps.

The adapter 1 can be removed manually by a worker, for example from an upstream device section or from a depot. Before the feed 3 into the station 9, the fitting piece 1 is then manually aligned or positioned by the worker who is handling the fitting piece 1 then manually transfers or inserts into station 9.

Alternatively, the automatic (pre)alignment or positioning of the fitting 1 is possible, for example in an upstream device section in which the fitting 1 is (pre)aligned and then the station 9 is automatically transferred or fed.

After feeding 3 the fitting piece 1 into the station 9, its alignment and/or positioning is checked in a checking station 11 and, if necessary, a correction 7 is carried out in a correction station 12.

For this purpose, the fittings 1 are transported through the device 2 by a transport device 10, the method steps preferably taking place during the continuous or discontinuous transport of the fitting. A check 4 and correction 7 while the fitting pieces 1 are passing through the device 2 is particularly advantageous since the fitting pieces 1 can shift, in particular during transport, and a correction 7 can be necessary before the feed 8 to the processing station 13 and the implementation of the processing step , in order to precisely align the fitting piece 1 before processing. In particular, continuous transport enables the process to be carried out economically, with speeds of 20 m per minute being able to be achieved.

Alternatively, the check 4 of a fitting 1 only takes place after processing in the processing station 13. This process sequence is in figure 1 not shown. Deviations of markings from the target marking course, for example a seam set during processing that deviates from the target course, are detected after processing and a correction specification or a correction value is determined, which is transmitted to the correction station 12 . The correction station 12 then carries out a corresponding correction for the subsequent fittings 1 so that the subsequent fittings 1 are correctly aligned before the feed 8 to the processing station 13 .

The check 4 is carried out without contact, for example by optically detecting markings on the fitting 1. The markings are preferably arranged on the surface of the fitting, for example in the form of a pattern, or in the fabric of a textile, for example in the form of the course of the thread or of stitches, seams or similar fabric markings and are detected optically. However, other detection elements can also be provided which are able to detect the markings without contact. For example, it is also possible to detect markings in the form of different pile heights by measuring distances. For this purpose, a sensor that carries out distance measurements can be provided, which detects the distance to the tips of the pile. If no deviation was found during checking 4, no correction 7 is required and the method runs according to the dashed line Y, so that after checking 4 the feed 8 to the processing station 13 follows.

An optical detection can take place by means of the human eye or by appropriate optical devices. The optically detected course of the marking is compared with a predetermined desired course of the marking. This is also done optionally by humans or by a suitable processing device 15, preferably a data processing device.

If detection and comparison are to be carried out by the human eye of a worker, the course of the desired marking can, for example, be depicted on the transport base or formed by the transport base over which the adapter 1 is transported. However, any other suitable implementation is also possible in which the person can visually compare the course of the marking and the course of the desired marking. The worker recognizes a deviation of the fitting piece course from the desired course and determines a correction value. The worker can determine this on the basis of empirical values and preferably transmit it to a correction station 12 by manual input into an operating element 20 , so that a manual correction 7 is carried out according to the correction value.

The detection by optical devices is preferably carried out by a sensor device 17 with at least one sensor or by a camera, wherein the fitting 1 is transported with a transport device 10 past the sensor device 17 or the camera and markings of the fitting 1 are optically recorded.

The sensor device 17 or the camera preferably detects the actual path of the deviation and the direction of the deviation, so that the exact Marking history is detected. With regard to the direction, it is detected whether the deviation transverse to the transport direction 23 is on the left or on the right. The path is also precisely recorded, ie to what extent there is a deviation. The path can be determined in mm, for example. These recordings are then compared with the course of the target marking so that an exact correction specification can be created in the relevant dimensions.

The sensor device 17 or the camera communicates with a processing device 15, the detected marking course being transmitted to this. The processing device 15 preferably has a computer 19 and a memory 16 coupled thereto, on which at least one target marking course is stored, with which the actual marking course is compared. A large number of different desired marking courses can be programmed and stored in the memory 16, which can be selected for comparison depending on the product to be produced or the production line.

In the event of deviations, the computer 19 creates a corresponding correction specification and makes this available for the correction 7 to be carried out. The correction 7 can then take place automatically by transmitting the correction specification as a corresponding control signal to the correction station 12, which automatically carries out the correction 7 according to the correction specification, so that no human intervention is necessary and a fully automatic correction 7 of the alignment of the fitting 1 takes place.

Alternatively, the correction specification calculated can also be displayed on a display panel 22 such as a monitor, so that a worker can read this specification and enter it into an operating element 20 communicating with the correction station 12 . The correction specification can be displayed, for example, in the form of a numerical value or comparable information and can be read by a worker. The operating element 20 is preferably coupled to the correction station 12 via a control unit 21 of the latter, the control unit 21 controlling the correction station 12 in accordance with the input into the operating element 20 .

An operating element 20 and/or a display panel 22 can also be present in the automatic correction 7, in which the actuating signal is routed directly to the correction station 12, for example for safety in the event of automatic failures or for individual adjustment.

The correction station 12 then carries out a correction 7 according to the correction value or according to the correction specification, so that the marking profiles are brought into agreement.

The correction 7 can preferably be carried out by transmission 6 of the correction value or the correction specification to a control unit 21 of a suitable mechanical component, with the control unit 21 controlling the mechanical component in accordance with the correction specification or in accordance with the correction value and this carrying out the correction 7 by means of a corresponding mechanical effect on the Fitment 1 through and brings the fitment 1 in a correct orientation. The correction 7 takes place in both directions transverse to the transport direction 23, since the Fitting pieces 1 can slip in both directions transversely to the transport direction 23 and a correction 7 is required in both directions. Only then can an exact alignment be achieved. Such a subsequent correction of the course of the marking and thus of the fitting piece 1 enables the exact positioning of the fitting piece 1 in the device 2, so that the fitting piece 1 can be precisely processed in the processing station 13 and a particularly high-quality product is produced. The check 4 and the correction 7 are therefore preferably carried out immediately before the processing step, so that the fitted piece 1 is fed to the processing in an exactly aligned manner.

The non-contact sensory check 4 also enables the alignment of edgeless fitting pieces, so that an individual and precise alignment and positioning can take place solely on the basis of patterns or, in the case of textile fitting pieces 1, on the basis of thread courses or similar textile markings. The fitting piece 1 can be processed in any manner, for example a hem can be sewn or the fitting piece 1 can be folded. After processing, a new check 4 and correction 7 can take place if, for example, further processing steps follow in which the fitting piece 1 must be precisely aligned, with the method steps being repeatable as often as desired.

In figure 2 the schematic structure of a device 2 for carrying out the method according to claim 1 is shown, the device 2 having:

• a station 9 to which the fitting 1 is (pre)aligned and/or positioned manually or mechanically,
• a transport device 10 connected to station 9 and possibly beginning before station 9, for transporting fitting piece 1 through device 2,
• a checking station 11, in which the actual marking course of markings on the fitting 1 is preferably detected by sensors and can be compared with a target marking course, with a correction value or a correction specification being created or able to be created
• a correction station 12 for the exact alignment of the fitting 1 according to the correction value or according to the correction specification,
• a processing station 13, preferably a fixing device, into which the fitting piece 1 is fed in an exactly aligned manner and can be processed.

The fitting piece 1 is fed (pre-)aligned automatically, preferably from an upstream device section, or manually by a worker to the station 9 .

A transport device 10 is connected to station 9, it being possible for station 9 itself to be a transport device 10 to which fitting 1 is fed or, if necessary, for transport device 10 to be arranged beginning in front of station 9 so that fittings 1 can be transported from the station 9 or through the station 9 to the subsequent transport device 10.

The station 9 can also be any other station 9, for example for carrying out a processing step.

With the transport device 10 , the fittings 1 are transported through the device 2 past the checking station 11 and the correction station 12 or through them into the processing station 13 . The inspection station 11 can alternatively be arranged downstream of the processing station 13, which is not shown in the figures. In this case, a check 4 takes place only after the processing of a first fitting piece 1. If a deviation from the desired course is detected, a correction specification or a correction value is transmitted to the correction station 12, which is arranged in front of the processing station 13, so that a Alignment corrected.

The checking station 11 and the correction station 12 carry out a subsequent correction of the fitting 1, so that the alignment of a fitting 1 that has been displaced from the desired position during transfer or transport by the device 2 is corrected before it is fed to the processing station 13, in which the Fitting 1 is processed into an intermediate or end product. This ensures a particularly good quality of the intermediate or end product.

3 shows a first variant of the device 2. The checking station 11 enables contactless detection of the marking course. For this purpose, the checking station 11 has a Detection device 14, which is a camera or a sensor device 17 with at least one optical sensor. The course of the fitting piece 1 can thus be detected, although it is also possible to detect a marginal edge or a pile edge, which can be used for alignment, since the edge is optically recognizable, but this is not absolutely necessary, since optical detection based on any Pattern or similar markings is possible. Alternatively, markings can also be detected by distance measurements. For this purpose, a sensor that carries out distance measurements is provided, which detects the distance to the tips of the pile.

In a processing device 15 of the checking station 11, which is coupled to the detection device 14, the recorded marking profile is then compared with the target marking profile and a correction specification is determined. This is done using appropriate technical means for data processing, with a computer 19 connected to a memory 16 being used in the exemplary embodiment. The course of the marking recorded with the camera or the sensor device 17 is transmitted to the processing device 15 or the computer 19 contained therein. The computer 19 then carries out a comparison of the marking course with a desired marking course stored in the memory 16, wherein different desired marking courses can be stored in the memory 16 or new desired marking courses for new production lines can be programmed in later. These are then selected depending on the production line and are available Comparison with a corresponding recorded marking history is available.

If the course of the marking deviates from the desired course of the marking, the computer 19 calculates a correction specification. Appropriate technical means are used to send the correction specification to a receiver in the correction station 12, which carries out a correction 7 in accordance with the specification. For example, the correction specification is transmitted to a control unit 21 of the correction station 12 in the form of an actuating signal from the computer 19 .

In this case, the checking station 11 is directly coupled to the correction station 12 for communication. This results in an automatic, exact correction 7 according to the correction specification, without human intervention.

The correction 7 can be carried out, for example, by a suitable mechanical component, with the control unit 21 controlling the mechanical component in accordance with the correction specification and this carrying out the correction 7 by appropriate mechanical action on the fitting piece 1 and bringing the fitting piece 1 into a correct alignment.

If there is no deviation, there is no correction 7 . The fitting piece 1 is then fed to the processing station 13 . The processing station 13 can be a fixing device in which the fitting pieces 1 are hemmed, glued or sewn, for example. However, it can also be a device for folding the fitting pieces 1 or for carrying out any other processing section.

In the processing station 13, an intermediate or end product of excellent quality is produced.

A second variant of the device 2 is in 4 shown. The detection of the marking course and the comparison with a target marking course takes place in the checking station 11 by the human eye. The comparison takes place, for example, by mapping the course of the desired marking used for the comparison on the transport base or by the transport base over which the fitting piece 1 is transported. The worker recognizes a deviation of the fitting piece course from the desired course and determines a correction value. The worker can determine the correction value on the basis of empirical values and transmit it to a control element 20 coupled to a correction station 12 by manual input, so that a manual correction 7 is carried out in accordance with the correction value. The correction station 12 has the operating element 20 for this purpose.

A third variant is in figure 5 shown. As in the first exemplary embodiment, the detection and comparison take place, namely in the checking station 11 by the detection device 14 (e.g. sensor) and the processing device 15, with the computer 19 of the processing device 15 being coupled to a display panel 22 and transmitting the calculated correction specification to it, which is displayed on the display panel 22. The correction specification displayed is read off and entered manually into an operating element 20 coupled to the correction station 12 . The correction station 12 has a control element 20 coupled control unit 21 and is controlled by this according to the input.

A fourth variant is in 6 shown. Here, the detection takes place with a sensor of a sensor device 17, with a light source 18 being arranged opposite this. During transport through the device 2, the fitting piece 1 is arranged between the sensor device 17 and the light source 18 and is transilluminated by the light source 18 so that the sensor can better detect markings, for example in the textile fabric of textile fitting pieces 1.

With the method and the device, both textile fittings and fittings made of any material that can be processed in the same way as a textile material are processed. This includes, for example, fitting pieces made of paper or plastic.

The in the Figures 7 to 11 The further device shown serves to align an edge region 101 of a preferably flexible piece of material 102.

This device can be used, for example, as a correction station 12 for exact alignment in the device 2 . The piece of material 102 is, in particular, a piece of textile material which is separated from a textile web and has a quasi-rectangular basic shape. The device consists essentially of a transport device 103 with an indicated machine frame 104 for pieces of material 102 with a driven transport means 105, for example a transport belt, and a support part 106 for the Transport means 105. In the exemplary embodiment, the support part 106 is designed as a plate. The piece of material 102 lies on this plate. The transport means 105 in the form of a belt drive rests on the top side of the piece of material 102 so that it is pressed against the support part 106 . The support member 106 is preferably a flat, smooth plate. The transport means 105, which is preferably designed as a transport belt of a belt drive, is combined with spring-loaded support blocks 107 on the upper side, which press the transport means 105 in the direction of the support part 106 in a spring-biased manner. These support blocks 107 are held on a part of the machine frame 104 . The visible part of the machine frame 104 is designed as an L-shaped folded piece of sheet metal, one leg of which is directed parallel to the extension of the support part 106, while the other leg is directed vertically thereto.

A region of the same located near the edge region 101 of the piece of material 102 is held or can be clamped between the support part 106 and the transport means 105 and is transported by the transport means 105 in a conveying direction 108 parallel to the edge region 101 . The edge area 101 is, as in the Figures 7 to 11 clearly visible, in order to clarify the alignment problem, it is formed so as to run in a wavy manner, so that the edge region is not aligned exactly parallel to the conveying direction, but rather runs in different shapes and at different distances from the transport means 105.

The support part 106 protrudes beyond the transport means 105 on both sides transversely to the conveying direction. The superior areas are given as 109 and 110, respectively. In the exemplary embodiment, a recess 111,112 with a peripheral edge 113,114 directed parallel to the conveying direction 108 is provided in both protruding regions 109,110 and is adjacent to the transport means 105 in each case. Instead of this, one edge 115, 116 of the protruding areas 109, 110 of the support part 106 could also be used appropriately, with this edge 115, 116 also being directed parallel to the conveying direction 108. Furthermore, above the edge 113 or 114 or also possibly above the edge 115 or 116, an adjusting means 117, 118 is attached directly to the machine frame 104, which can be moved from a basic position, which is, for example, in figure 7 , figure 9 and figure 10 is shown, in which its functional components lie outside the plane that is spanned by the gap between support part 106 and transport means 105, in the exemplary embodiment above this plane, can be adjusted into a working position that in figure 8 and figure 11 is shown, in which the adjusting means reaches through the plane, ie is positioned with components, so to speak, below the projecting area 109 or 110.

During the adjustment movement, the adjusting means 117 or 118 is moved past the edge 113 or 114 or 115, 116 transversely to the conveying direction 108 and transversely to the above-mentioned plane, at a relatively small distance therefrom, taking with it the area located next to the transport means 105 of the piece of material 102, as in particular in figure 8 and figure 11 is clarified.

Depending on the required alignment, the edge area 101 or the edge area 101a, which lies on the other side of the transport means 105, can be aligned with the positioning means 117 or 118, respectively. With a movement of the actuating means 117 from the position according to figure 7 into the position according to figure 8 or from the position according to figure 10 into the position according to figure 11 a transverse force is exerted on the corresponding edge area 101 or area 101a of the piece of material 102, which moves the piece of material 102 away from the transport device 103 in the area in which the adjusting means 117, 118 engage, in order to precisely align the course of the edge area 101 as desired.

In order to ensure that the piece of material 102, in particular the edge of the piece of material 102, is carried along when the adjusting means 117,118 is adjusted from the basic position to the working position, in the adjusting path of the adjusting means 117,118 on the support part 106, specifically in the area of the recess 111,112 on the conveying direction The front edge of this recess holds a pivotable support 119, against which part of the adjusting means 117, 118 presses when adjusting to the working position and the support, as for example in figure 8 visible, pushes down transversely to the conveying direction. The intermediate edge area 101 of the piece of material 102 is held between the adjusting means 117, 118 and the support 119, so that the desired movement of the edge area 101 transversely to the conveying direction 108 after takes place below, in particular based on the figure 11 is clarified. The length of the adjustment path of the adjusting means 117, 118 from the basic position to a working position for the purpose of correctly aligning the edge area 101, 101a of the piece of material 102 can be adjusted, for example by means of an operator, so that depending on the deviation of the edge of the edge area 101, 101a from the desired position, a larger or smaller Adjustment path is executed.

In particular, the support 119 is attached to the support part 106 in a resiliently movable manner, in particular to the edge of the recess 111, 112 that is at the front in the conveying direction 108.

This ensures that the support 119 is automatically moved following the adjustment path when the adjusting means 117, 118 is adjusted.

The drawing does not show that the adjusting means 117 , 118 is designed as a skid, roller or stamp at its free end facing the piece of material 102 . This is one possible configuration. In this case, however, the actuation of the actuating means, i.e. the adjustment of the actuating means from the basic position to the working position, would have to take place intermittently, so that during the transport of the piece of material 102 in the conveying direction 108, the edge region 101, 101a located under the actuating means can be pulled by the actuating means accordingly in order to to get the exact alignment.

It is preferably provided here that the adjusting means is a belt drive 120, 121 with a driven roller 122 and a free-running roller 123, around which the belt of the belt drive 120 or 121 runs and is moved.

As a drive for the driven roller 122 of the adjusting means 117, 118, a motorized rotary drive 124 is held and fastened to frame parts, for example parts of the machine frame 104, which is connected to a drive shaft 126 via a coupling means 125, in the exemplary embodiment a drive belt. For this purpose, the drive shaft 126 additionally has a roller 127 firmly connected to the shaft. The drive shaft 126 is mounted and guided in a mounting block 128, the mounting block 128 in turn being fastened to parts of the machine frame 104 so as to be fixed to the frame. The drive shaft 126 is firmly connected to the driven rollers 122 of both adjusting means 117,118, so that rotation of the drive shaft 126 starts the belt drive 120,121. The direction of rotation of the coupling means 125 (the drive belt) is indicated at 129 . In addition, the adjusting means 117, 118 can be adjusted by means of an adjusting drive 130 attached to the machine frame 104. For this purpose, the actuating drive 130 consists, for example, of an electric motor drive 131, which can be set in motion alternately to a limited extent to the right and to the left. A disc-shaped driver 133 is rotated clockwise or counterclockwise about the axis formed by the output shaft 132 to a limited extent via an output shaft 132 . At this driver are on coupling rods 134.135 and connecting rods 136.137, 138.139 components Adjusting means 117, 118 pivotable about the drive shaft 126. By rotating the driver 133 by means of the drive 131 in one direction (e.g. clockwise), the adjusting means 117 is moved into the working position, in which the entire element having the belt drive is pivoted from a basic position into the working position, in which the free-running roller 123 is adjusted downwards, such as in figure 11 is evident. This movement of the driver 133 raises the actuating means 118 located on the other side. If the driver 133 rotates in the opposite direction, the adjusting means 117 is raised, while the adjusting means 118 is lowered analogously by the free-running roller 123 being moved downwards. This arrangement ensures that not both adjusting means 117,118 can act on the piece of material at the same time, but only the respectively selected adjusting means 117,118, as determined by the user.

In order to achieve perfect guidance of the edge region 101,101a of the piece of material 102 in the conveying direction 108 even after it has passed over the recess 111,112, an inclined guide part 140 is arranged following each of these recesses 111,112, which in the conveying direction is continuously variable in the following region of the projecting region 109 or 110 of the support part 106 passes.

In the exemplary embodiment, the actuating means 117,118 are formed by actuators rotating in the same direction as the conveying direction 108, in particular belt drives 120,121, the rotating actuators being at least when the corresponding actuating means is to be moved from the basic position into the working position, lasts and is continuously driven in rotation during the working position. As a result, the edge region 101, 101a is processed in adaptation to the conveying direction and the conveying speed of the piece of material 102, in order to achieve the correct alignment of the edge region 101 or 101a.

The deviating position of the edge area 101, 101a from the target position can be visually detected by the operator, so that he can operate the corresponding device as intended. However, it is also conceivable and possible to detect the edge region 101, 101a or its edge by means of suitable detection devices with regard to its position and to actuate the actuating means 117, 118 as intended by means of corresponding machine controls.

The in the Figures 7 to 11 The device shown is suitable and intended for enabling a method for aligning an edge region 101, 101a of a piece of material 102, in particular a fitting piece of textile. For this purpose, the piece of material 102 is transported close to an edge region 101, 101a by means of a transport device, for example the transport means 105, in a conveying direction 108 parallel to the edge region. The piece of material is pressed against the support part 106 of the transport device 103 by means of the driven transport means 105 of the transport device 103 and is transported along the support part 106 in the conveying direction. The one described The device and procedure can of course be provided on both sides of the piece of material 102, so that corresponding devices are positioned and installed on both edge areas. The piece of material can hang down freely between the device parts arranged on both sides, for example by forming a loop.

As intended, the support part 106 protrudes beyond the transport means 105 on both sides transversely to the conveying direction 108. A recess 111,112 is provided in the two protruding areas 109,110, which is located below the corresponding area of the piece of material 102. If the alignment of the piece of material 102 deviates from an exact target alignment of the piece of material 102, namely if its edge region 101 or 101a is warped closer to the transport means 105, the differently aligned region or edge region 101, 101a of the piece of material 102 is pushed over the edge of the material piece 102 running parallel to the conveying direction 108 Supporting part 106 or pulled over the marginal edge of recess 111, 112, which runs parallel to conveying direction 108 and is adjacent to transport means 105, and is thus moved transversely to conveying direction 108 and transversely to transport means 105 by a corresponding amount from transport means 105, i.e. pulled away, so that the deviating orientation of material piece 102 is corrected and transferred to the exact target alignment.

The tension that acts on the material strip in the area of a corresponding adjusting means 117, 118 is applied by vertical force. so that good power transmission and alignment is achieved. During the application of the tensile force, the means applying the tensile force is preferably moved parallel to the conveying direction 108 of the transport means 105 or additionally applies a movement component parallel to the conveying direction 108 to the material strip, so that a distortion of the piece of material is avoided. The movement of the means parallel to the conveying direction 108 or the movement component is adapted to the speed of the transport means 105 in order to achieve a trouble-free effect on the material strip and in particular to avoid folds. In order to facilitate the alignment, the piece of material 102 has a visually recognizable edge or edge or a marking, line or step running parallel to the conveying direction 108, so that the alignment that deviates from the target alignment is recognized by a means executing or monitoring the alignment process and a technical device is started Is used for exact target alignment of the piece of material. The monitoring means may be an operator's eye, or it may be an electrical, electronic, or other sensing means.

With the specified device and the specified method, it is possible in an excellent manner to align the edge area of a flexible piece of material as intended, so that subsequent work processes such as forming a hem and sewing a hem can then be mechanically connected. In particular, the alignment is to be made during normal operation of the transport device 103, so that a exact alignment can take place during the normal transport process.

The invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the claims.
