JPS5847978Y2 - Roll with uneven pattern on wall surface - Google Patents

Description

[Detailed explanation of the invention] Conventionally, immediately after applying a coating material to a wall surface, a roll with an open-cell polyurethane sponge or partially acetalized polyvinyl alcohol sponge pasted on the surface with an uneven pattern formed on the surface is rolled. There is a construction method that involves pressing and creating an uneven pattern on the surface of the coating material.

However, although all of these rolls are expensive, partially acetalized polyvinyl alcohol sponge rolls must be swollen and softened with water before use, and moreover, as they repeatedly absorb water, swell and shrink, they dry out and shrink. There were drawbacks such as the roll becoming gradually deformed, the diameter of the roll being partially out of alignment and not making uniform contact with the surface of the coating material, and the pattern being deformed.

The advantage of these textured rolls is that they easily contain the coating liquid, but because the sponge cells have to be made large and continuous, the shells that make up the pores tend to become thin or thin. As a result, durability decreases, and this tendency is particularly severe for polyurethane sponge rolls.

The present invention uses fibers that are much stronger than the materials that make up these sponges, and forms an uneven pattern with the raised portions and missing portions of the same fibers, making it inexpensive, durable, and highly absorbent. The molding method allows rolls to be manufactured easily and inexpensively, and examples will be described below with reference to the accompanying drawings.

A base fabric 3 in which relatively stiff naps 2 are densely grown is wound and adhered to the circumferential surface of the roll base 1, and an uneven pattern is created by the naps 2 and the naps 2 and the naps 2. Form.

The nap 2 mentioned above is a fiber of thermoplastic synthetic resin such as nylon, accelerator, polyethylene, polypropylene, or polyvinyl chloride, thin tape, animal hair, vegetable fiber, etc. made of dense nap or loops of any fiber, or flocked cloth. The raised raised portion 4 can be formed by melt-pressing using heat or chemical methods, electro-flocking, mechanical cutting, or by weaving an uneven woven pattern cloth.

Further, the cutout portion 4 may be formed before or after winding onto the roll base 1.

In the figure, 5 is a handle, and 6 is a support shaft.

In this invention, as mentioned above, the uneven pattern is formed by the napped fibers and the missing parts of the napped fibers, and the hardness and softness can be freely adjusted depending on the fiber properties, thickness, length, etc., and the absorbency is also the same as the napped fibers. Since the density can be adjusted, it is possible to easily and inexpensively produce a molded roll having an uneven pattern with the optimum hardness depending on the coating material and pattern, and it also has the effect of being easy to wash after use.
