DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production method for continuously forming surface patterns of various fabrics on the surface of vinyl by utilizing thermoplasticity. That is, a cloth having a desired pattern is formed on the heated vinyl surface by pressing the cloth with a desired unevenness along an engraved roll having desired irregularities, thereby creating a cloth-like engraving pattern on the vinyl surface.

[0002]

2. Description of the Related Art Conventionally, a method has been adopted in which a sculpture imitating a pattern of a cloth ground is formed on the surface of a pressure roll and the sculpture is transferred to a vinyl surface.

[0003]

When the conventional method of pressing with an engraving roll is used, the cost for producing one engraving roll currently costs 500,000 to 1,000,000 yen.
In addition, since a pattern having an accuracy closer to a cloth is technically difficult, it has been necessary to commercialize the pattern with an insufficient shape.

[0004]

[Means for Solving the Problems] When engraving rolls that are to be engraved at a high cost are not commercialized and are not expected to sell reliably, they often take a second step in production and abandon normal production. In the present invention, a wide variety of patterns can be created by crossing an engraving roll with a cloth, and processing can be performed from a small number of samples, and the economy can be sufficiently maintained.・

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, while the vinyl of (1) is softened by a heating heater of (2) and a heating drum of (4), the pressure between the pressure rolls (6) and (7) is reduced. With the cloth of (5). By this (5)
Is transferred to the vinyl of (1). In this work, the pressure roll of (6) is replaced with an engraving roll with large irregularities, so that the surface with the cloth pattern of (5) and the irregular engraving pattern are added. You can get a pattern. After the transfer under pressure, the fabric is cooled by a cooling drum, and the fabric of (5) and the vinyl of (1) are separated and wound up, and the fabric is reused.

[0006]

EXAMPLE In the present invention, the number of uses of the fabric greatly affects the profitability.
Most of them obtained results that could be used up to 20 times.

[0007]

The precision of the transfer pattern of the vinyl surface obtained according to the present invention is not the ratio of that obtained by the engraving roll, but a natural result as if it were the cloth itself. In the case of an engraving roll, the glossiness changes after a certain period of use, so that re-plating is required, and if it is damaged during the operation, there is an unexpected risk of repair or re-engraving. These problems are unlikely to occur in the present invention.

Claims (1)

(57) [Claims] 1. A method in which a cloth is attached to heated vinyl chloride leather and a sheet, and when the cloth is passed between two rolls, the roll on the cloth side is engraved with large irregularities. A manufacturing method that creates a pattern on a vinyl surface that combines a fabric surface pattern and a roll pattern.
