Description

[Detailed description of the invention] Method and equipment for manufacturing tapes, especially patterned label tapes Technical field The present invention relates to a method for manufacturing a tape, particularly a patterned label tape, and a device for carrying out the method. Regarding preparation.

prior art The seeding method mentioned at the beginning and the equipment concerned are known from EP-A-0389793. It is being In that case a wide fusible fabric is produced and a hot cutting element is cut along the cutting line. It is cut into tapes and then the tapes are heat set.

During the cutting process, the molten material generated at the cut part produces relatively hard and rough bumps or edges, which will interfere with the appearance and handling of the cut tape. In EP-A-0389793 According to the tape with a fused edge, the edge area is located in the hollow area of the tape, parallel to the edge. Fold it back along the fold line, thus forming a folded edge, and then fold the folded edge along the corresponding fold line. Attempts to avoid the above disadvantages by adhering the tape strips to the adjacent surface area .

Hot press the overlapping parts for two. The molten thread that has been fed into it Therefore, the adhesive layer can be melted and fixed, or the adhesive layer can be activated by applying pressure, cutting the adhesive thread. Bond the fabric threads in the cutting area by arranging them in the area and applying heat and pressure By making the threads of the textile base of the cloth so that fraying or no longer occurs after the cutting of the cloth or combined with each other. Also in that case especially thin and flexible cutting areas are made. Ma In particular, with this method and equipment, not only fabrics made of thermoplastic yarns, but also especially non-thermoplastic yarns can be produced. The advantage is that fabrics made of thread can also be processed.

This is because a fixed cutting area along the cutting line is cut with a mechanical cutting device, e.g. scissors. This is because it can be done.

In any case, the heat setting after the cutting process will ensure that the cutting area is completely smoothed out. Guarantees smudge-free tape.

Advantageous configurations of the method are defined in claims 2 to 14, advantageous configurations of the installation, or claim 6. It is described in Ishi-23.

According to claim 2, the cutting area can be formed as a single-ply fabric, whereas claim 3 It is even more advantageous to form it as a hollow area.

Regarding the arrangement of the fused thread and/or adhesive thread, as is clear from claims 4 to 8, A wide variety of possibilities arise.

Particularly in bleached cloth, individual pattern threads are exposed in the E area. However, the present invention According to the method, it is possible to completely fix such a thread in the hollow area or in the cutting area.

On the one hand, by heat treatment and on the other hand, by pressing, the melt is transferred to the fibers of the fabric. Since it is pushed into the tube, the floating line is also securely fixed. Claims 9 and 10 are hollow The various possibilities of arranging the weft threads in the area are described.

Best results will be obtained if the fabric is cut in the center of the cutting area. According to claim 11, Cutting with mechanical cutting equipment is recommended, especially when the material is made of fabric or non-thermoplastic fiber materials. can. In the case of fabrics made of thermoplastic fiber material, cutting according to claim 12 is even more advantageous. It is.

In some cases, the cutting area may be given a circular, wedge-shaped or other sharp appearance, for example. In order to achieve this, it is preferable to further shape the cut area after cutting according to claim 3. Methods and equipment so that knitted or especially woven fabrics can be manufactured and processed as fabrics. be able to configure preparations.

The device for forming the cutting area may be adapted to form a hollow area or an overlapping area according to claim 16. You can configure it so that it looks like this.

The tape manufacturing equipment is a mechanical cutting device according to claim 17 or a thermal cutting device according to claim 18. A device can be provided.

The pressing device can be constructed according to claim 19 or according to claim 20. The structure is even more advantageous.

Individual stamping of the cutting areas is thereby possible. In that case, the press equipment Heatable according to claim 21 - in two rolls formed as a heavy or double roll. Wear. Further, according to claim 22, there is provided a tool for pressing the cutting area while applying heat. Also possible are a pump or three pipe lane device.

Particularly preferred is a structure according to claim 23. In that case, on the other hand, the tape has a special On the other hand, the cutting edges of the tape are cut to give the appearance of This is because it can be further processed.

Cut The cutting area 34 also consists of a hollow fabric section 38 on the back side of the base fabric 36. In this example In this case, instead of individual ordinary warp threads 6, fused threads and/or adhesive threads 14b are used in hollow areas. 34 are woven into the fabric on both sides. In the example in Figure 2, the fused thread is used regardless of the warp thread. In the case of the woven fabric shown in FIG. It will be done. In addition, in the example shown in FIG. I can't stand it. When pressed while applying heat, the molten thread and/or adhesive thread 14b melts. , forming a molten zone 42 . This fused area bonds the remaining threads together.

Figures 6 and 7 show the cut area 41 or the city 4b formed as a single-ply fabric section. Vertical The thread 6 and the weft thread 8 also form the basic fabric 43, and the weft thread 40 for patterning It is woven into the foundation fabric 40. Melted in place of the normal warp thread 6 in the cutting area 41 Yarns and/or adhesive threads 14C are woven. The melted thread and/or adhesive thread 14c is heated It melts by pressing under the action of The cutting area 4j is cut along the cutting line 10 to form the melting area 42. The threads that are affected by cutting can be combed or fixed.
