Definitions
- the present invention relates to a process for the continuous production of a carpet according to the preamble of claim 1 and to webs which are formed from longitudinal upright thread and transverse weft thread, which are connected to one another, for the production of this carpet according to the aforementioned method .
- DE-A-2 307694 shows the cutting of a fabric web in strip form, which is set up, strung together and connected to one another in the area of the fabric, so that a flat structure is obtained, one surface of which consists of the free weft yarn ends. These strips are connected to one another in the area of the other surface.
- the connection of these strips takes place in magazines in which the individual strips are placed one on top of the other.
- the strips are previously provided with an adhesive. This adhesive is then dried in the magazine, which can be done by heating the magazine walls or, if it is a hot melt adhesive, melted so that the connection can be achieved.
- a known method for the continuous production of a carpet developed by the applicant consists in that the longitudinally cut strips of a fabric web are introduced in stack arrangements and stacked on top of one another. These stacks are fed to a belt arrangement and placed thereon in such a way that the strips lie transversely to the belt running direction. On the belt, the stacks held between two webs are passed through a device in which an adhesive is applied which forms a layer on the surface facing away from the belt and connects the individual strips and the stacks with one another, so that a continuous carpet web is formed .
- a disadvantage of this method is the complex handling, which consists in that the strips arranged one above the other in stacks each have to be fed to a further device for applying an adhesive, where the strips are ejected from the stacks onto the tape. This requires the appropriate facilities, which are expensive to purchase and maintain.
- An object of the present invention is to improve the method for the continuous production of a carpet in such a way that in particular the handling is simplified and the necessary equipment can be carried out more easily.
- a carpet web can be produced in a continuous manner from a web which is made up of upright thread and weft thread, which are connected to one another, without the continuous process being interrupted.
- the adhesive is advantageously applied in the form of a powder, after which a heating device is passed through, in which the powder is sintered and a layer is formed which forms the back of the carpet. In this case, this back can additionally be provided with a second back for reinforcement in a known manner.
- a further advantageous embodiment of the method consists in the fact that the web is a woven web, and that binding threads are used to produce the woven web, which are at least partially formed from a hot melt adhesive.
- the fabric web thus produced is passed through a first heating device, in which the hot melt adhesive of the binding threads is melted and a firm connection is made with the weft thread, so that the strips subsequently obtained by the slitting process are stable.
- the heating device for sintering the adhesive applied in powder form to form the back of the carpet there is also an optimal connection with the hot melt adhesive of the binding threads and the weft thread.
- a web can advantageously also be used which is formed at least from upright thread and weft thread, which are connected to one another by sewing seams running along the upright thread. This ensures optimal cohesion of the slit strips.
- the width of a strip is significantly different from the thickness of the fabric web from which the strips are cut, it is necessary to bring the strips together before the adhesive is applied to connect the individual strips to one another.
- the resulting carpet web will then have a smaller width than the supplied web.
- the width of the strips substantially corresponds to the thickness of the web, which simplifies the manufacturing process.
- the carpet web produced according to the invention can advantageously be wound up as a roll in a winding device.
- the strips joined together according to the invention come so close to one another that the weft thread's effect as carpet pile is lost and only a "textile covering" can be perceived, which is a loss of quality of the desired carpet is to be viewed.
- a further object of the present invention is therefore that the web is designed as the starting material for the longitudinally cut strips for the production of the carpet web so that the spacing of the individual strips from one another is such that the desired tightness of the carpet pile can be achieved.
- this object is achieved by a fabric web as defined in the characterizing part of claim 6 or by a web as shown in the characterizing part of claim 12.
- the arrangement of the weft threads in a double layer and the attachment of spacer threads in the area of the binding threads of the fabric web has the consequence that the weft threads have a sufficiently large spacing from stripes to stripes, as a result of which the pile effect of the resulting carpet web is optimally preserved.
- a spacer thread is attached to the outside of each layer of the weft thread, which is woven in in a simple manner during the manufacture of the fabric web.
- any desired pattern can be achieved on the carpet to be produced in the production of such fabric webs by changing the colors of the weft thread and / or the type of weft thread.
- spacing threads can advantageously be arranged on one side, which are respectively opposite the upright thread, the upright thread, the weft thread and the thread being applied when a sewing seam is made along the upright thread Spacer thread is penetrated by the sewing thread.
- the upright thread of a strip runs continuously in the carpet web to be produced, it can be designed as a line for the transmission of signals and energy.
- FIG. 1 shows a schematic illustration of a side view of an installation for producing a continuous carpet web
- Figure 2 is a view of part of the longitudinal section.
- Figure 3 is a sectional view transverse to the weft through a fabric web which is used for the production of carpets.
- FIG. 4 shows a sectional view through the fabric web along line IV-IV according to FIG. 3;
- FIG. 6 shows a plan view of a part of the longitudinally cut strips of the fabric web and the resulting carpet web; 7 shows a schematic illustration of a side view of part of a further installation for producing a continuous carpet web;
- FIG. 8 shows an enlarged view of the area of the system according to FIG. 7 in which the sewing process takes place.
- FIG. 9 is a sectional view through the web along line IX - IX according to FIG. 8.
- a fabric web 1 is fed to a cutting device 4 via guide and tension elements 2 and a dancer roller 3 in the direction of the arrow.
- the fabric web 1, the weft threads of which run transversely to the feed direction, can originate directly from a loom, not shown.
- the fabric web 1 Before the fabric web 1 reaches the cutting device 4, it can, for example, additionally be guided through a humidification system, not shown, in which the fabric web is moistened.
- the fabric web 1 moistened in this way can then be passed through a freezer, not shown, where the dampening solution freezes.
- the fabric web to be cut lengthwise can be temporarily strengthened without soiling it.
- binding threads 23, 24 (FIG. 3) can be used, which for example have a core which is formed from glass fibers, whereby the required tensile strength of the binding threads is obtained, and the are provided with a coating consisting of a hot melt adhesive.
- the so-equipped tissue web then passes through a heating ein ⁇ not shown 'rect, in which the enveloping melt adhesive melted and a fixed connection between binder yarns and weft is formed.
- the humidification and freezing system described above can be dispensed with in this version.
- the fabric web 1 is cut into longitudinal strips, as will be described in more detail later.
- the fabric web 1 cut in this way in longitudinal strips is continuously transported further by a conveying means 5 and arrives in guiding means 6.
- the guiding means 6 is also intended to ensure that the longitudinally cut and twisted strips are then continued in parallel and are in contact with one another.
- the web 7 formed by these longitudinally cut strips passes through a device 9 for applying an adhesive which is in the form of a powder.
- This powder is spread over the entire surface, after which a heating device 10 is passed through.
- the adhesive which is in powder form, melts, as a result of which a continuous layer is formed on the surface which forms the back of the resulting carpet.
- the individual longitudinal strips of the web 7 are connected to one another, so that a continuous carpet web 11 is formed.
- a second back can be attached to reinforce the back of this carpet web, which has, for example, the shape of a fabric.
- the continuous carpet web 11 thus formed is passed through a pair of pull rollers 12, which pull rollers 12 can also be designed as cooling rollers at the same time, and is wound up in a winding station 13 to form a carpet roll 14.
- These carpet sheets, supplied in rolls, which can have a width of approximately 80 cm to 120 cm, for example, are easy to lay. In particular, such carpets can be used Laying should be joined together along the long sides without the joints being visible, since in principle only two strips of carpet need to be joined together.
- the cutting device 4 consists of a smooth roller 15, which has a hardened surface, and a knife roller 16 arranged parallel thereto.
- Disc-shaped knives 17 are arranged on the knife roller 16, the mutual distance between which corresponds to the width of a strip . Through these knives 17, which are pressed firmly against the smooth roller 15 and rotate at the same peripheral speed as the smooth roller 15, the fabric web 1 is cut into strips 18.
- the fabric web 1 which can be produced in a known manner on a loom has two layers 19 and 20 of weft thread 21. These two layers 19 and 20 of weft thread 21 are separated from one another by upright thread 22. The weft threads 21 are connected to one another by binding threads 23, 24, as a result of which the fabric web 1 is formed.
- spacer threads 25, 26, which run transversely to the weft thread 21, are attached to the fabric of the fabric web 1 on both sides. These spacer threads 25, 26 are each wound around a weft thread and skip the following three weft threads on the outside.
- the cuts by which the respective strips 18 are formed are indicated by dash-dotted lines 27. It can be seen here that the binding threads 23 and 24 of the weft threads 21 have set in one edge region of the strips 18, so that the weft threads 21 are free in the other edge region. These free ends of the weft thread 21 form the pile of the carpet thus obtained.
- FIGS. 5 and 5a each show a section of a corresponding carpet sheet 11 in a section that is transverse to the carpet sheet 11.
- the illustration according to FIG. 5 shows the individual Strips 18, which are connected to one another to form this carpet web 11 by the applied layer 28, which is formed from an adhesive and which forms the back of the carpet web 11.
- the spacing threads 25, 26 prevent the individual strips 18 from juxtaposing to form the carpet web 11, so that the strips 18 come too close to one another, so that the free ends of the weft threads 21 have a certain freedom of movement, thereby creating the desired pile of the carpet can be formed.
- the upright threads 22, which run continuously along a manufactured carpet sheet 11, can at least partially be formed, for example, from electrical conductors.
- electrical conductors for example, telephone connections or computer connections etc.
- the connection cables are not then free in the room, additional installations are not required.
- Fig. 6 shows in a plan view of the fabric web 1, as by
- the carpet web 11 is formed, as has been described for FIG. 1.
- the width of the individual strips 18 is essentially the same as the thickness of the fabric web 1. This means that the total width of the resulting carpet web 11 is approximately the total width of the supplied fabric web 1 corresponds.
- the longitudinally cut strips 18 can therefore continue to run essentially in a straight line when rotated through 90 ° and to form the carpet web 11.
- FIG. 7 there is a continuous supply of upright thread 22 arranged in parallel next to one another from bobbins (not shown).
- a layer of weft thread 21 is attached above and below this upright thread 22.
- the individually drawn in weft threads 21, which are cut to length, are brought into position by a comb-like slide 31 and by means of guide elements 32 arranged in a funnel shape, where they are held in a known manner by guides 33.
- a spacer thread 25 is placed on the upper layer of weft thread 21 corresponding to each upright thread 22.
- a continuous sewing seam 34 is attached along the upright thread 22 or the spacing thread 25, for which purpose sewing needles 35 are provided, as will be described below.
- the web 36 thus formed then passes through the cutting device 4, which in this exemplary embodiment consists of two creel knives 37, 38 arranged one behind the other, which perform a reciprocating movement. With the first gate knife 37 every second longitudinal cut is made, while in the second gate knife 38 the intermediate longitudinal cuts are made.
- every second strip 18 can be diverted upwards from the path plane, while the other strips 18 can be diverted downwards from the path plane, as can be seen in FIG. 7.
- the strips 18 rotated in this way are, as has been described for FIG. 1, passed on for further processing to form a carpet tape.
- the weft threads 21 are drawn in pairs within the guide elements 32 and cut to length. These weft threads 21 are then pressed by means of the comb-like slide through the gap 41 formed by the guide elements 32.
- the sewing seam 34 is made immediately behind, the sewing thread 42 penetrating the spacing thread 25, the upright thread 22 and the weft thread 21.
- the sewing seam 34 is carried out as a single chain stitch, although other types of stitch are also conceivable.
- the sewing seams are made simultaneously over the entire width of the web 36 formed in this way, which can be, for example, 1.2 m.
- a multi-needle sewing machine 43 is used, which is known and which is only indicated schematically here. After sewing, the web 36 thus formed is cut into strips 18, the cutting lines being designated 27. The strips obtained in this way are further processed as described above.
- the fabric web 1 as well as the web 36 can be formed in a known manner from threads which have different colors, thicknesses and materials, as a result of which a large variety of very different carpets can be created with this production method.
- At least the spacer thread 25 and the upright thread 22 are preferably of the same thickness.
