Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, as a loop lining for a passenger car, the one shown in FIG. 7 is known.

This is done by using fabric such as stockinette fabric as the reinforcing layer 4, backing and polymerizing the covering material 23 on the resin layer 3 usually made of a vinyl chloride resin sheet, and molding it from the original fabric into a size and shape that fits the ceiling. , and the bag member 2 at an appropriate interval
7 is sewn or welded, the wire 22 is inserted through this bag portion, both ends of the wire 22 are engaged with the hanging material 25, the facing material 23 is lifted up, and the periphery of the facing material 23 is wrapped with a welt molding 26. It is formed by fixing a hanging material 25 or the like.

In this case, the facing material is once manufactured continuously to form a raw fabric, this raw fabric is cut appropriately, and the bag-like members are further made into
1L, 14M, and Yarona Nzono had the disadvantage that it is easy to use a commercially available raw material for multiple purposes, and by adding consideration at the raw material stage, This is caused by not researching ways to reduce the number of subsequent processing steps.

Therefore, in the present application, a part having the same function as the bag member is provided between the resin layer and the reinforcing layer, or in the reinforcing layer itself, at the stage of manufacturing the original fabric, so that the part corresponding to the bag part is already integrated at the time of manufacturing the original fabric. The purpose of this is to omit the bag member attaching step, which was conventionally required as post-processing.

In this application, the base fabric is made of two layers, sewn together at an appropriate pitch, and the welded reinforcing layer and resin layer are continuously fixed together.The original fabric is cut into the required shape for the ceiling, and wire is inserted into the space between the base fabrics. The purpose is to provide ceiling covering materials that are designed to be inserted.

In addition, in the present application, a reinforcing layer and a resin layer are continuously fixed together, and the base fabric is a loop woven fabric having loops of the size of a hanging bag.The original fabric is pressed into the required shape for the ceiling to form loops. To provide a ceiling covering material into which wires are inserted.

Furthermore, in the present invention, when fixing the reinforcing layer and the resin layer, the reinforcing layer is provided with unevenness in advance, and the original fabric is continuously fixed integrally with the resin layer and cut into the shape required for the ceiling, and the unevenness is formed on the reinforcing layer. To provide a ceiling covering material in which a wire is inserted into the space thus formed.

Furthermore, in the present application, adhesive is applied at intervals to the overlapping surface of either the reinforcing layer or the resin layer, and the original fabric is fixed together, cut into the required shape for the ceiling, and wires are attached to the parts that are not glued. The purpose is to provide ceiling covering materials that are designed to be inserted.

Furthermore, in this application, a masking member (a band-like member, an anti-adhesive agent made of an oil-based substance, etc.) is attached on top of the resin layer, and it is fixed integrally with the reinforcing layer, and if a band-like member is used as the masking member, it can be removed. In the case of an anti-adhesive agent, the area will not adhere, so a space will be formed.

To provide a ceiling covering material in which the original fabric formed in this way is cut into a required shape for the ceiling and wires are inserted into the space. Furthermore, the present application provides a manufacturing method in which each of the ceiling covering materials described above is continuously formed into an original fabric.

In order to achieve the above object, an embodiment thereof will be explained based on the drawings. In the case of FIG. 1, the wire 22 (seventh
The reinforcing layer 3 is made of vinyl chloride, polyethylene, nylon, polyester, or other synthetic resin. A covering material 23 is produced continuously and at high speed by integrally polymerizing a resin layer 4 which is a sheet-like material using rollers 5 and 6, and is wound into a roll shape to form an original fabric 7. .

In this case, ordinary means such as adhesion and pressure bonding can be used to polymerize both layers 3 and 4. Welding is also possible depending on the combination. The same applies to each of the following examples.
5 In the case of FIG. 2, a reinforcing layer 3 formed by loop weaving so as to have loops 8 of a size equivalent to a hanging bag is applied to a resin layer 4 on a base fabric 1, and a roller 5,
At 6, the raw fabric 7 is formed by polymerization. Third
In the case shown in the figure, the rollers 14 and 15 have concave portions 12 and convex portions 13 that engage with each other at regular intervals, and the recesses are large enough to insert the wires 22 into the reinforcing layer 3 at regular intervals. 16, and at the same time the reinforcing layer 3 and the resin layer 4 are integrally polymerized by rollers 14 and 6, so that spaces are formed between both layers 3 and 4 at an appropriate pitch. It forms the

In addition, when providing a recess, it may be provided in the resin layer 3 contrary to the above example, or it is also possible to provide it in each of both layers 3 and 4. In addition, by increasing the unevenness of the roller to create a toothed cross section, the saw layer can be polymerized in a wavy manner. In the case of FIG. 4, a sponge is used as the reinforcing layer 3 instead of a woven fabric, a knitted fabric, etc. A sponge sheet with recesses 17 formed in advance is used, and the reinforcing layer 3 and the resin layer 4 are connected by a roller 5, 6
A raw fabric 7 made of a facing material is integrally polymerized with the above materials.

In this case, the material for the sponge sheet is one made of thermosetting resin such as polyurethane foam, and one made of thermoplastic resin such as polyethylene foam.
Both can be used.

The reinforcing layer 3 may be formed with unevenness in advance, but
If there is a risk that the recesses 17 may be flattened by the pressure applied by the rollers 6 during polymerization, the rollers 6 may be moved up and down in synchronization with the pitch of the recesses 17. In addition, when using a weak sponge material that makes it difficult to maintain the shape of the recess 17, it may be impregnated with a thermosetting resin such as phenol resin and hot press molded, or conversely, it may be impregnated with a thermoplastic resin. After heat press molding, it is sufficient to cure the molded material sufficiently.
Note that if the thermoplastic resin is impregnated with a heat-sensitive adhesive, by heating the rollers 5 and 6 in the polymerization process,
Both layers 3 and 4 can be easily bonded and polymerized without requiring a new gluing process.

Furthermore, the polymerization method may be replaced by a press machine in which a mold provided with recesses is continuously moved up and down without using the rollers 5 and 6. Incidentally, unlike this example, it is also possible to perform polymerization in the same manner as shown in FIG. 3 without forming recesses in the sponge sheet in advance. In the case of FIG. 5, the adhesive 20 is intermittently applied to the inner surface of either one or both sides of the reinforcing layer 3 or the resin layer 4 by means of a gravure roll 19 to integrate the adhesive, and the portions that are not to be adhered are appropriately fixed. This is to form an original fabric 7 produced at pitch.

Also, both layers? It is also possible to simply press or heat-weld without using an adhesive. In this case, at least one of the rollers 5 and 6 may be moved up and down intermittently, or unevenness may be provided at an appropriate pitch around the roller, or a heated portion may be provided on a portion of the circumference of the roller. good. ; In the case of Fig. 6, resin layer 4
A masking member 21 (a band-shaped member, an anti-adhesive agent made of an oily substance, etc.) is attached on top, and the reinforcing layer 3 and the resin layer 4 are polymerized together with the reinforcing layer 3 using rollers 5 and 6. If a band-shaped member is then used, it is extracted and a facing material with a void 1 formed therein is produced to form the original fabric 7. Note that the size of the masking member 21 is taken into consideration so that the resulting cavity is large enough to insert the wire 22. The above has been explained based on the drawings, but the main point is that the present application intermittently reinforces the resin layer 3 and reinforcing layer 4 when they are fixed together using rollers 5, 6 or other fixing means. It is important to form the original fabric 7 by continuously and rapidly manufacturing the facing material, which is formed by continuously forming void spaces for wire insertion on the side of the layer 3, and the method and apparatus are as follows. The present invention is not limited to the embodiments described above, and the design may be changed as appropriate, without departing from the gist of the present application.

Furthermore, it is clear that the covering material 23 in which the original fabric 7 formed as described above is cut into the shape of a roof for an automobile Z and the wire 22 is inserted into the blank space of the original fabric 7 is another gist of the present application. It is.

Further, as the material for the reinforcing layer 3, a PVC sheet, a resin heat insulating material, a PVC foam, a PE or PP foam, a polyurethane foam, a knitted fabric such as knitted fabric, a woven fabric, a non-woven fabric, etc. can be used.

Furthermore, as the resin layer 4, a PVC leather sheet is generally used.

In addition to the above-mentioned embodiments, the original fabric 7 is formed by moving the pressure roller intermittently up and down to form areas that are intermittently bonded and areas that are not bonded, and wires are inserted through the areas that are not bonded. It is also possible, and this case also does not depart from the gist of the present application. 24 is the roof of the car, 25 is the hanging material for the wire 2 provided on both sides of the roof 24, 26
2 shows a welt molding that is integrated with the roof 24, the hanging material 25, and the resin layer 4.

As described above, the present application is a ceiling covering material in which spaces through which wires can be passed are provided at regular intervals in advance when polymerizing a reinforcing backing layer and a surface resin layer, and a method for manufacturing the raw fabric thereof. It has a similar effect.

B. In the conventional process, a predetermined shape is cut from a raw material made of closely laminated materials, and hanging bags for inserting wires are provided at several locations over several steps.

However, in the present application, a void space having a function equivalent to a hanging bag can already be integrally provided in the same process as the conventional fabric manufacturing stage. Therefore, by cutting the original fabric into a predetermined shape, it can be used immediately as a ceiling covering material, which greatly reduces the number of conventional processes and eliminates the need for processes that require time and skill. Since the upholstery material is manufactured in a uniform manner through mass production, it eliminates variations in quality such as meandering sewing lines that occur in traditional manual finishing.

C. Since the hanging bag is omitted, the weight of the ceiling is reduced, which is advantageous.

2. As with conventional hanging bags, there was a risk that the sewn parts would peel off during use, but in the present application, the adhesive area between the laminated layers is much larger, so there is no such fear. It's powerful. E) Conventional ceiling interior materials have had a heat insulating material interposed between the roof and the facing material, but in the present application, when a sponge material is used as the reinforcing layer, insertion of the heat insulating material can be omitted.
