Description

The invention relates to a device with which layer material, such as paper, foils or the like, can be processed, transported and / or divided. The sheet material is expediently flexible and can have a weight of less than 500, 200 or 100 g / m ² , for example be suitable as packaging material with which a package, such as a stack of paper, is wrapped tightly.

Especially for the production of rectangular or similar Packaging sheets or the like. The material is useful as Web from a storage device, such as a roll, pulled off and in continuous throughput of one or more slitters fed, which on one or both long sides opposite each other a border strip from the Cut off the web and thereby the desired width of the packaging sheet establish. After the longitudinal cut, the web divided into separate sheets by cross sections, after which the sheets are either stacked flush or immediately be fed to a packaging station in which them mechanically so completely one by one packaging unit are folded so that this is complete is covered. Around the sheets to packaging units of different widths adjust or the longitudinal section in different Lay areas of the material too wide is at least one slitter by hand or with a drive cross-adjustable and in its respective Fixable working position. This also applies to any other linear processing, the working width of which is essential less than half the width of the material or a tenth of it is.

The tool, such as a cutting or Shear roller, disengaged from the material, then cross-adjusted and brought back into engagement with the material become. The two, thereby offset against each other Longitudinal machining is then not continuous connected to each other via a corresponding cross processing. In the case of a cut, the front end is one Longitudinal section and the offset rear end of the other Longitudinal section then not through a continuous connection cut linked together, bringing the two together closing, differently wide sections of the Edge strip remain connected to the rest of the material web and separated from it in a separate operation need to be around the edge strip as a continuous waste strip to be able to lead away from the rest of the material. Moreover is the conveying movement of the material web for the transverse adjustment to interrupt so that there are large downtimes result for the cross adjustment.

From EP 0 692 370 A1, which forms the basis for the preamble of claim 1, is a system for producing corrugated cardboard sheets with a changeable Format became known, which is a rotatable and swiveling knife disc having. This knife disc works with a fixed cutting table. Both are pivotable about an axis far from the point of the cutting intervention, so that they are in a transverse adjustment to change the cutting width to carry out a have the oblique cut adjusted.

The invention is based on the object of a device and to create a method of the type described in what disadvantages of known procedures or the described Are avoided and the particular one Cross adjustment of the respective processing zone in a shortened Allow time or without stopping the device.

Control means are provided for the respective Tool unit during the transverse adjustment in immediate To keep engaging with the material and / or around during the cross adjustment the continuous or a slower longitudinal and feed movement between tool unit and not to interrupt material, but to continue. This means that from the beginning to the end of the transverse adjustment avoid that time is needed to the tool unit to bring out of work or around the To stop the feed movement. This is particularly advantageous if the material is machined in a tool gap becomes common, its opposing limitations be adjusted in the manner mentioned.

Since the tool unit is designed as a shear slitter so that it for the machining requires a predetermined track alignment, namely an alignment parallel to the processing line, it is expedient with regard to this track alignment continuously variable, for example similar to a steered wheel of a vehicle around a single, axis perpendicular to the material plane pivotable, which goes through the engagement area, in which the tool unit processes the material. The steering angle, the transverse movement and the feed movement can are superimposed on each other in such a way that the two meet each other parallel, but cross-staggered longitudinal sections or the like via a continuous straight connection or bevel cut or the like. Connected directly to one another are at an acute angle to the longitudinal cuts. The However, overlay also enables a polygonal or curved connection cut or a corresponding other Editing that is only part of the so edited Go through material width or across the entire material width can. It could therefore also be used with the longitudinal machining Tool a line-shaped processing perpendicular to the Material web, for example a complete cross separation, be performed.

The tool unit has two on both sides of the Tools directly opposite each other on, which at the same time in the material of both sides intervene and can be rotated in opposite directions. Both tools guide the feed movement, the transverse movement and / or the steering movement together so that their mutual Relative position always remains the same. A tool can thereby to support the material during processing or against the machining pressure of the other tool and in the case of a tailor the material is not form penetrating shear edge with which the other, the Tool penetrating material interacts. The Mounts or bearings of the two tools are over a beam rigidly connected to one another during processing laterally outside of the not yet processed or already processed material and is on only one or be stored on both sides of the material level in steering bearings can.

The steering axis passes through the material and the material plane penetrating part of the carrier lies in the feed direction, especially in the feed direction of the material, with respect to the longitudinal axis and / or the processing zone offset so that it is always in the area of the already processed Section of the material lies and immediately adjacent penetrates the material level to the associated side edge. When cutting, the mentioned support part then always at a short distance adjacent to the cutting edge of the material part continuing in the material level.

The tool unit or its holder or storage is on a parallel to the material plane and perpendicular to the Feed direction movably mounted cross slide, the or its sled bearing, based on the Feed direction, on the side facing away from the carrier part mentioned Side of the processing point, e.g. in the feed direction of the material upstream of this processing point. The distance of the slide bearing from this processing point or the steering axis can be smaller than the distance of the carrier part passing through the material plane.

A drive, for example, is used to carry out the steering movement a linear drive, such as a fluid drive, is provided, which carries out the transverse movement and on the sled is stored. This actuator or steering drive is controlled in this way that he started with the transverse movement, so during the impulsively short acceleration to the otherwise constant speed of transverse movement Steering movement and changing the orientation of the tool unit executes what during the constant transverse movement no steering movement takes place. The works accordingly Steering movement even during negative acceleration which stops the constant transverse movement, whereby then the steering angle is opposite to that Tool orientation returns, which before the transverse movement was given. The steering movement can be in these two end positions each rigidly fixed by a stop, so that despite the fast steering movement a very accurate Alignment results.

The stops can advantageously be changed in position by adjustment, to change the steering angle. In case of a straight line bevel machining is the constant speed the transverse movement expediently equal to the tangent of the Helix angle of the bevel machining multiplied by the Feed speed. The helix angle compared to the Advance direction is advantageously at most 60, 30 or 20 ° and at least 3 or 5 °, preferably about 10 °. Advantageous are on both sides of the longitudinal median plane of the material or the like. Two identical or mirror-symmetrically arranged or different work units are provided to do that Material simultaneously at two separate processing points to edit, in a common, to the median longitudinal plane perpendicular transverse plane are provided.

These work units are independent of each other and / or Can be moved synchronously in opposite directions, for which separate cross drives or a single, common transverse drive is provided could be. The sledge bearings of these work units can be aligned. Fixed guides or Rails for the transverse movements can be rigid on one Device frame or between its side cheeks be attached, which laterally outside the material width stand.

Regardless of the training described, the invention proceed in such a way that the layer material and the tool unit without interruption, possibly with a delay, of the feed movement are cross-adjusted against each other. Even if the tool unit is motorized out of machining intervention would still result for the cross adjustment a significant reduction in time compared to a procedure, at which the feed for the transverse adjustment is interrupted. The one not processed during the transverse movement Longitudinal section of the material could then like that with Longitudinal sections provided by direct machining cross sections adjacent to its two ends with a separate tool of the device from the material web separated out and discharged as waste.

The movements to be superimposed electronically or via a computer or computer with a Processor controlled. The movements or their speeds are detected with sensors and via signal lines conveyed to the processor. A corresponding signal line can also take measurements of a working unit in the running direction downstream processing station for the material to the Mediate processor and thereby predetermined programs for trigger the overlapping movements. For example can the size of the respective in the packing station Packing unit recorded and then automatically the material web variable in the respective width range be machined lengthways. It can therefore be in continuous Pass consecutively different material sections Width with a common longitudinal median plane are produced, of which on both sides of the longitudinal median plane removed edge strips despite different broad longitudinal sections continuously contiguous from those material sections are separated, which for Further processing is determined. A substantial time saver also arises if for the transverse adjustment Feed movement stopped, the tool unit or that separate tool but machining in engagement with the Material stands.

The device 1 is used for processing and processing an endless from a roller conveyor fed, constantly wide web of substrate material 2, the longitudinal edges 3 parallel to each other lie. The material 2 is under permanent tension adjacent and parallel to the two edges 3 along one processing line 6 at a time in continuous Run worked. But it can only are processed along a single line 6. Of this Line 6 to the opposite line 6 or this associated edge 3, the material 2 then forms an opposite the starting material 2 narrower strips 4, which intended for further processing into single sheets or the like is by transverse cuts, perforations or the like. in strip 4 separated from each other or limited against each other become. On the side facing away from strip 4 everyone Line 6 connects a narrow edge strip 5, which as Waste can be carried across. The width of the stripes 4, 5 can during the material run as well as during the Processing symmetrical to the longitudinal center plane 11 of the material 2 can be changed, the total width of the strips 4 and 5 remains the same as a widening of the stripe 4 to narrow each strip 5 by half leads to this broadening; the same applies vice versa if the Strip 4 becomes narrower.

1, the strip 4 is narrower Editing, with dot-dash the transition to the wider one Processing is indicated. In the area of narrower machining form the strips 4, 5 and the lines 6 longitudinal sections 7 with only parallel edges, in the transition area Longitudinal sections 8 with oblique edges and in Area of the wider strip 4, in turn, longitudinal sections 9 with only parallel edges. In the longitudinal direction of the Material 2 go all strips 4, 5 and lines 6 each continuously over all sections 7 to 9 through which the strips 5 continuously from the strip 4 can be separated.

The material 2 is processed in a horizontal Material level 10 managed while maintaining the tension parallel to its longitudinal direction and to Level 10 conveyed at constant speed. The for Level 10 right-angled reference level 11 is parallel to Longitudinal and conveying direction 17 of the material 2. Each line 6 or the tool unit producing this defines one Processing level 12 or 13, which is in the manufacture all sections 7 to 9 perpendicular to level 10, at Production of sections 7, 9 parallel to level 11 and at the manufacture of the sections 8 at an acute angle from 10 ° to level 11, then both inclined levels are provided symmetrically to level 11.

The processing of both lines 6 takes place in the area or linear processing points 16 of less than 10 or 5 mm wide, which is perpendicular to plane 11 are adjacent to each other. Each position 16 can only be used a single tool or with two on either side of the plane 10 horizontal tools can be processed. Any of these Tools has a zone closest to level 10 or the greatest penetration of level 10 and this zone lies in a plane 14 perpendicular to planes 10, 11 or 15, which is an axial plane of the associated tool can be. The two levels 14, 15 are in funding or Feed direction 17 of the material 2 slightly against each other offset, in particular such that the axial plane 14 of the the material 2 does not penetrate, on the underside of the material lying tool against direction 17 opposite Axial plane 15 of the other tool is offset, which the material 2 from its opposite side, namely the top, piercing and shearing with the underlying tool interacts. Positions 16 then lie between levels 14, 15 and are through that Zone defined in which the material 2 of both Tools is first recorded simultaneously.

The two interacting tools form one Work or tool unit 25 and are on separate Working heads 26, 27 held or movable, in particular rotatably mounted. A tool 28, especially the lower one Tool, has a cylindrical peripheral surface for linear Support of the material 3 and is on a Front side, possibly with a low axial system tension, from other, upper tool 29 overlapped. This tool 29 forms a circular sharpened cutting edge on the outer circumference, which directly in that face of the Tool 29 is which of the shear and face mentioned of the tool 28 is facing and cooperates with this. The axes of rotation 14, 15 of the tools 28, 29 lie always parallel to each other. At level 11 and direction 17 parallel alignment of the tools 28, 29 are located Axes 14, 15 perpendicular to level 11 and the two Tools 28 on the one hand and the two tools 29 on the other of the two units 25 are axially aligned.

When the units 25 are aligned obliquely, the axes of the Tools 28 and 29, respectively, at an obtuse angle to each other or at an acute angle to plane 11, which then axes 14 on the one hand and axes 15 on the other hand, cut at the same point. The working diameter the one tool 28 can be slightly larger than the one of the other tool 29, the two Tools 28, 29 with their peripheral areas a funnel-shaped the mouth narrowing to position 16 for the Form material 2. The point 16 can be in the common Axial plane of the two tool axes 14, 15 lie.

The locations 16 are simultaneous and synchronous in opposite Directions 18 perpendicular to plane 11 and movable parallel to level 10 so that they are opposite the Level 11 always have the same distances. Furthermore, each Unit 25 pivotable about a single axis 20, which perpendicular to plane 10 or direction 17 and is parallel to level 11 to 15. The axis 20 can in the respective levels 14, 15 and at right angles to the tool axes lie and in particular coincide with the point 16.

The pivoting movements of the two units 25 about the longitudinal axis 28 take place synchronously in opposite directions in directions 19, so that the units 25 always the same angle to the Take level 11. The alignment parallel to level 11 of the units 25 represents a middle position, from which the two units 25 in both opposite directions the same angular amounts can be swiveled to a limited extent can, so that there is a very simple control. Starting from this middle position, the maximum is here Swivel angle 10 ° in every direction, but it can also do more than 40 or 90 °.

1 is a narrow section 7 of the strip 4 in Pass cut in direction 17 in that the material 2 is processed in both places 16 simultaneously. If the strip 4 is to be widened, the units 25 on the one hand at the same time with the positions 16 same speeds in the directions 19 on the diverging oblique traces of section 8 aligned and on the other hand they become simultaneously in directions 18 spread apart while editing at the points 16 is continued without interruption.

The pivoting movements about the axes 20, which are in the planes the machining end faces of the respective tools 28, 29 lie only over a part going to zero the length of the inclined sections 8 of the lines 6, so that the Transition to these sloping sections is not or only very much is slightly rounded.

In the further course, the oblique sections 8 of the Line 6 cut while the feed motion and the Cross movements are continued. As soon as or just before the Set 16 of the units 25 the desired distance from each other have reached which of the greater widths of the strip 4 or the greater distance between lines 6 in section 9 corresponds, the units 25 are again in the level 11 parallel alignment returned. Also this retroactive Steering movement takes place at the end of the inclined sections 8 just like the deflection at the beginning, so that the ends too the oblique sections 8 are not rounded or only slightly rounded merge into sections 9 of lines 6. The strip 4 can now continue with the changed, however again constant and here wider width further processed or cut.

Between the two sections 7, 9 of the strip 4, 5, the have constant width, section 8 is continuous with itself changing width formed which the sections 7, 9 connects in one piece and in direction 17 after Device 1 with cross sections separated from the material 2 can be. The strip 4 can accordingly conversely, can also be made narrower at any time. The despite the change in width continuously from strip 4 severed strips 5 are immediately in direction 17 after the points 16 and the tools 28, 29 across the plane 10 deflected downwards and immediately into a container transferred.

The device 1 has a rigidly to be arranged on a foundation Base frame 22 on, in particular two laterally outside the material width parallel to level 11 contains standing side walls and cross members 24, which these rigidly connect both cheeks. Essentially all components of the device 1 can immediately attached or stored on this frame or the cheeks his. The device 1 can also be a pre-assembled one Be unit, which as a slot on the top of the Base frame 22 is to be arranged interchangeably and at right angles used for direction 17 or parallel to level 10 or can be removed.

In this case, the rack 22 is one of the base rack separate, rigid frame of the device module 1, whose cheeks are level with those of the base frame lying and rigid during processing with this are tense. In any case, the level 10 is appropriate at a distance above the cheeks, so that the material 2 and the positions 16 are easily accessible at all times. Between Cheeks and on this or a cross member 24 are two identical, always mirror symmetrical on both sides of level 11 lying carriage 23 in the directions 18 back and forth movably mounted, which in Fig. 2 with solid lines in their end position closest to level 11 and with dash-dotted lines in their end position of greatest distance are indicated by level 11.

4, the left cross slide 23 is in its end position greatest distance from level 11. In Fig. 2 are only the lower tools for the sake of clarity 28 of the units 25, and in Fig. 5 is the associated unit 25 is not shown to lie below it Clarify parts. On each carriage 23 is one of the two units 25 pivotally mounted about the axis 20, both identical units 25 always mirror-symmetrical to Level 11 lie, but also like the points 16 in the direction 17 could be offset from each other.

The respective carriage 23 is completely at a distance of and below level 10 and points one to level 10 as well plate-shaped base 30 at right angles to direction 17, on the rails 31 of the frame 22 exclusively in the Directions 18 can be moved back and forth. The upstream the rails 16 lying on the points 16 are superimposed on the side facing the positions 16 of the Traverse 24 rigidly attached and are like the base 30 with Distance from this side. On the associated plate side 30 rotatable or track rollers 32 are rotatably mounted on the base, which on the rails 31 positively guided are that the carriage 23 transverse to the plane 10 and parallel to Direction 17 is stored without play. Instead of roles, too other runners 32 are provided.

For the transverse movement of the carriage 23 is a common one Drive 33 is provided, which is adjacent to said side the traverse 24 and like this completely below the level 10 lies. It is also conceivable to have separate drives for both Carriage 23 or units 25 to be provided, so that this independently or asynchronously or simultaneously can be moved or pivoted. In this case sections 7, 9 of strip 4 and 5, respectively, when maintained the specified width offset laterally lie.

The drive 33 has a on the said side between the Rails 31 and the cross member 24 and the base 30 lying Drive member 34, namely an endless, toothed Strap 34 on two adjacent to the inside the frame cheeks lying deflections 35, such as toothed Rolling, is performed without slip. The two up to the Deflections 35 parallel runs of the toothed belt 34 parallel to plane 10 or directions 18 and one above the other, since the axes of the deflections 35 are parallel to the plane 10 and lie to direction 17. The deflections 35 are on the Traverse 24 rotatably mounted. The upper run is with one Clamp 36 or the like. Tightly attached to a carriage 23 and the lower run is attached to the other carriage 23, so that the opposite movement of dreams directly affects the Carriage 23 is transmitted. The fastenings 36 allow a continuous adjustment of the carriage 23 relative to the Drive member 34 in the opposite directions 18. Die Clamps 36 are on the same side as the rotor 32 on the Base 30 attached.

For each rail 31 there are two runners one behind the other 32 provided so that the carriage 23 is mounted tilt-free. The superimposed runners 32 are on each other turned away longitudinal edges of the rails 31, each adapted to the grooves of the rotor 32 and at an angle to each other form lying flanks. One of the deflections 35 is from a motor or gear motor 37 driven, the Motor axis perpendicular to level 10 and its gearbox output lies in the axis of this deflection 35. The engine 37 is attached to the cross member 24.

The two heads 26, 27 of the respective unit 25 and the Mounts or bearings of the tools 28, 29 are rigidly connected to one another via a carrier 40, which only on the side facing away from the sled storage Side of the points 16 and after the strips have been led across 5 through the plane 10 perpendicularly. This allows the Carrier 40 upstream of the associated point 16 in extension of the associated strip 5 lie without disturbing.

The carrier forms on the back or underside of level 10 40 at the level of the lower rail 31 and the lower run of the Belt 34 a parallel to the plane 10, angular or U-shaped Temple with legs of different lengths 38, 39, 41. From axis 20, which is downstream of base 30, protrudes against the level 11 a first arm 38, which in the Axis 20 is rotatably supported by a bearing 45. With distance between the axis 20 and the plane 11 connects to the arm 38 rigidly an arm 39 protruding in direction 17. On this Arm 39 encloses in the direction 17 at a distance from arm 38 the plane 11 directed arm 41, which is the axial plane 12 of the axis 20 penetrates.

On the side of level 12 facing away from level 11 connects an arm 42 to the free end of the arm 41, which is level 10 at a short distance from the deflection the strip 5 is interspersed at right angles across and in a straight line and at a distance above level 10 into an upstream directional arm 43 passes. With distance between the vertical Support 42 and the level 14 carries the arm 43 on his free end of a support body, such as a plate 44, which over arm 43 protrudes upward and to level 11. At the for The head 27 is plane 10, the plate 44 lying transversely perpendicular Non-destructively attached. The head 26 is on that lower support bracket, for example only on the arm 39, with a box or angular holder or the like. Rigidly attached. As a result, both heads 26, 27 form a rigid one during operation Unit around the axis 20, for example the cutting line between the levels 12, 14 and 13, 14 is pivotable.

The carriage 23 could also be located downstream of the rails 31, for example in the area of the support 42, with another Rail 31 to be guided to support its weight here, the carrier 40 above the rail on a Support plate of the base 30 could be pivoted.

Said unit with the tools 28, 29 could be self-aligning or self-steering, e.g. by doing the axis 20 of the associated point 16 against direction 17 is subordinate enough so that the tools of the storage 45 are pulled or towed. expedient is, however, a drive 46 for the steering movement, for example a piston-cylinder unit, provided in parallel to level 10 and at a distance below level 10 approximately in the plane of the support bracket or arm 39 may be arranged can and always obliquely to the directions 17, 18 in plan view lies. One end of the drive 46 is in a bearing 47 hinged directly to the base 30 and that other end in a bearing 48 on the support bracket or closely adjacent to the outside of its U-cross leg 39 to section 41 is arranged. The drive 46 is optional in both opposite directions with a fluid drivable to the distance between the bearings 47, 48 to enlarge or reduce. The pivot axes of the bearings 47, 48 lie parallel to axis 20.

It is conceivable to use one or both tools 28, 29 without to provide direct drive so that, for example only due to the relative feed movement between material 2 and tool are driven or are rigidly held. Here is a drive 49 for a tool 28 provided that rigidly with the said holder on the arm 39 is attached. The motor of the drive 49 is at right angles transverse to level 14 and parallel to level 10 at a distance below this level 10 directly at the top of the Bracket or arm 39. The shaft directed against the base 30 of this motor 53 drives one carried by the motor 53 alone Gear 54 on which lies in the axis or plane 14 Output shaft the tool 28 arranged interchangeably is. The motor 53 and the bevel gear 54 form with the Tool 28 the head 26, the non-destructive detachable on the carrier 40 is arranged. The other tool 29 is by the Intervention in the material 2 and in the tool 28 to this driven in opposite directions. The tool 29 is required therefore no separate drive motor, although a such could be provided.

To limit the steering deflection of the entire unit 25, 26, 40 stop means 50 are provided, which are at a distance below level 10 at the level of the support bracket 38, 39, 41 or lie below the carrier bracket or drive 49, which in turn overlaps the top of this bracket. A stop 51 is provided on the carrier 40 or bracket, which on one over the outside of the arm 39 to the plane 11 protruding extension of the arm 38 rigidly attached is. On both sides in the movement path around the axis 20 parallel to the plane 10 pivotable stop 51 are on the Base 30 fixed counter-stops 52 attached below of the bracket 38, 39, 41 and the drive 46 are. After this the unit 25, 26, 40 from that in FIG. 5 on the basis of the plane 14 indicated center position has pivoted through the angle 21 lies the associated stop surface of the stop 51 by the pneumatic drive 46 resilient at the associated stop 52, which is continuously adjustable with respect to the base 30. A stop is mounted directly on the base 30 and the others on a stop bracket, which in the direction of 17 over the base 30 protrudes and on the same side of the base 30 how the entire support 40 and the drives 46, 49 lie. In the stop position, the unit 26, 27, 40 is rigid aligned.

The rotary bearing 55 for the tool 29 is opposite that Carrier 40 and the tool 28 parallel to the direction 18 with a bearing 56 slidably mounted and in the direction of displacement with a gearbox, for example one in one Rack engaging pinion or the like. Manually movable or in the respectively set position with a clamping device manually fixable. The two interlocking Sled members of the bearing 56 are with the unit 27 interchangeable, since the slide guide is interchangeable the side of the plate 44 facing the components 30, 31 is attached. The bearing is on the slide of the bearing 56 55 at right angles to level 10 with a bearing 57 manually adjustable relative to the tool 28 and the carrier 40, being an actuator parallel to level 15 Spindle drive can be provided.

The tool 28 is only on its level 11 facing Front through the gear 54 and not on the other Front side stored, the first-mentioned end face in the Level 12 or 13 lies and in overlapping engagement with the larger end face of the one-sided Tool 29 stands. Through the described, compact and very rigid training, the carriage 23 can almost up be brought closer to each other for a stop. The Positions 16 lie in the facing end faces of the two tool sets 28, 29.

To guide the material 2 in the area of 16 and in Direction 17 before and after is a guide device 60 with fixed and movable guide members 58, 59 are provided, which, for example, table or sliding surfaces for the Form material 2 and be formed by sheet metal plates can. A guide member fixed relative to the frame 22 58 extends symmetrically on both sides of the plane 11 and can protrude freely on the traverse 24 in direction 17 be attached. Its support and sliding surface lies in the Level 10. Also on every transversely movable unit, for example at the slide base 30, a guide member 59 is rigid attached, the support and sliding surface only by the thickness of the Guide member 58 set back against its sliding surface is.

In the direction 17 the links 58, 59 extend at most to the Carrier support 42 against which the free end of the Link 59 further set back than the free end of link 58 is. These ends form rounded quarter-circles Deflections to the strip at the free end of the guide member 59 5 in the manner described from the level 10 down lead away. The guide member 58 also covers the cross member 24 and the guide member 59 from the rails 31 with the rollers 32. Both Guide members 58, 59 can also be the tool 28 essentially cover and from the peripheral zone of the tools 28, 29 in Area 16 be penetrated. For this, the Guide member 58 a window extending in the direction 18 on so that it does not hinder the lateral adjustment. The For this purpose, guide member 59 closely relates to the peripheral sector of the Tool 28 adapted window. With its level 11 facing edge engages under the guide member 59 the other Guide member 58 in any position. The links 58, 59 lie always between the side walls of the frame 22. The deflection the strip 5 takes place in front of the supports 42 of the supports 40, which, seen in direction 17, U-shaped and above the Level 10 are not supported on the frame 22.

This redirection takes place through the training described always on the side of the motor 53, gear 54 and arm 39 over to an area below this. The same also applies to section 41, on the inside of which Strip 5 is passed down. This allows the Strip 5 guided past the carrier 40 without contact become.

The change in the useful width of the strip 4 or 5 or the lateral displacement of the point 16 can be done with control means 61 be fully automated so that it is for the expiry a side shift is only necessary, manually or sensor-controlled a corresponding command to the electronic To give control means 61. The control means 61 included an electronic processor 62, the control functions of which with the help of an input 64 and / or with a programmable Unit 65 can be changed manually. The processor 62 acts directly or under via signal lines Interposition of an interface 66 on the drives 37, 46, 49 so that after entering a command the associated driven links 23, 25, 28, 29 on each other and on the Longitudinal feed 17 matched or overlapping each other for carry out the necessary movements.

The geared motor 37 contains control means, e.g. an encoder or pedometer or incremental encoder 63, for electronic Control of the rotation speed, the rotation phase as well a motor brake in both opposite directions. The processor 62 acts on these control means 63 via a Signal line. The converter 66 actuates fluid valves Control of drives 46 in both opposite drive directions.

As an example, processor 30 receives an instruction to towards the end of a work program the distance between the parallel cutting planes 12, 13 to increase the width of the Strip 4 to wider ones to be packed in the packaging station, Adapt packaging units. As soon as the Band length of the strip 4 between the points 16 and Packing station has reached a sufficient length to the narrower packaging units still to be processed to pack, processor 62 controls drives 46 so that the distance between the bearings 47, 48 is shortened the drive 46 decreases, the material 2 continuously continues.

The units 25 swing about the axes 20 from the central position over the angle 21 to the stop 51 on the at the Base 30 strikes directly attached stop 52. As a result, the levels 12, 13 diverge in the opposite direction 17 or opposite level 11. At the beginning of the swivel movement or at the same time the drive 33 is controlled so that the two carriages 23 at the same speed from each other and move away from level 11. This movement takes place at a speed proportional to the tangent of the angle 21 according to the formal Vq = Vm x tang 21. Here Vq is the Cross speed of the individual carriage 23 and Vm die material speed above zero 2 parallel to direction 17.

Have the units 25 the predetermined distance from each other or reached from level 11, the carriage 23 with the brake of the drive 33 is stopped and the drives 46 return the units 25 to their central position, in which they then also compared to the corresponding one Carriage 23 with a lock separate from the drive 46 or be positively locked with stops can. Levels 12, 13 are in this middle position again aligned parallel to level 11. As soon as the diagonally cut Intermediate section 8 between the two longitudinal sections 7, 9 constant width of the strip 4 in the area arrives at the packing station, he is at this station as Garbage passed and the wider longitudinal section more constant Width is available for processing as packaging material Available.

During these operations, strips 5 become continuous led away to level 10. The heads 26, 27 or tools 28, 29 do not require motor drives to cross them Level 10 to move relative to the carrier 40. You can however, for example with the actuator 57, manually from the Level 10 moved away and thus out of mutual interference to be brought.

Downstream immediately adjacent to location 16, a Sensor 67 can be provided, which the quality of processing or the like. This sensor 67 is above the Level 10 and is above this on the carrier 40 or the support 42 attached so that it is transverse to each of the levels 10 to 15th can be adjusted relative to the point 16. The two End positions of each carriage 23 are by means of slings or switch 68, which the same cam 69 in the actuated respective end position. The the rails 31 and the Belt 34 overlapping cams 69 is on the unit 25 facing away from the base 30 attached. The limit switches 68 can be attached to the cross member 24 and are about Signal lines connected to processor 62. When reached the end position, the drive 33 is stopped immediately.

All specified effects and properties, such as orientation etc., can be exactly as described or only approximately or essentially as described, but also a lot of it be provided differently. The bases, for example the Levels or axes 10 to 15, the position 16, the directions 17 to 19 and axis 20 related positions can be related can also be provided vice versa on the respective basis.
