Abstract

PURPOSE:To enable the title device to form easily an original decorative surface where different patterns are combined with each other, by a method wherein an embossing roll is formed by juxtaposing and fixing at least two top and bottom roll groups whose surfaces are provided with necessary uneven patterns. CONSTITUTION:A top and bottom roll groups 3, 4 in an embossing roll 2 are controlled by a motor-driven gear mechanism so that they turn relatively at the same speed. Then right and left of the surfaces of those top and bottom roll groups 3, 4 are embossed with uneven patterns 8, 9 different from each other, the top and bottom uneven patterns 8, 9 embossed are engaged with each other and the top and bottom roll groups 3, 4 are turned without sliding. Embossing processing of a sheet material 13 sent into among those top and bottom roll groups 3, 4 is performed as a sheet material 13' showing such a natural pattern change as not to discriminate a boundary between uneven patterns 8, 9.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a continuous embossing process in which, for example, a thin strip-shaped metal plate is continuously pressed to create an uneven pattern such as wood grain or stucco on the surface. This invention relates to a roll device (hereinafter simply referred to as a roll device).

[Conventional technology]

It is common knowledge in the field of metal processing to insert a metal plate between two rolls that are in contact with each other and to plastically process this. However, it is extremely difficult to create different patterns continuously and freely in combinations of patterns on desired parts of a metal plate to be processed. Furthermore, clear line patterns tend to appear at the boundaries between different patterns, which has the disadvantage of causing twists, cracks, irregularities, and the like.

[Purpose of the invention]

In order to eliminate such defects, the present invention provides an embossing roll formed by fixing two or more upper and lower rolls in parallel, each having a desired uneven pattern on its surface, so that the uneven pattern coincides and overlaps, causing the roll to slip. The purpose of the present invention is to propose a roll device that dramatically improves production capacity, product processing quality, and design by mounting the above-mentioned roll group vertically on a frame so that they rotate in sync without any problems.

[Structure of the invention]

A typical roll device A according to the present invention is shown below using drawings.
An example will be described in detail. That is, in FIG. 1, 1 is a suitably reinforced frame, and on the frame 1, adjacent embossing rolls are vertically mounted,
Moreover, the lower roll group 3.4 is, for example, a gear machine driven by a motor! (not shown), they are controlled to rotate at relatively the same speed. To further explain the embossing roll 1 in detail, as shown in Fig. 2, (1)), it creates different uneven patterns 8.9 on the left and right sides.

The plate material 13 is mainly made of metal plates (color Y4 plate, aluminum plate, PVC plate, stainless steel plate, Zan 1 Goitch quick-turning, clad steel cross-section, etc.). ]-1
Both lower rolls 1 and 4 have a full (interlocking concave and convex pattern 8

A plate material 13 that does not slip is used. That is, the upper and lower tensions [7-11. However, it is possible to do both by applying a load of 8 in the opposite direction to the rotation direction. Sara? To explain this, the upper tension roll 11 rotates at the same speed as the embossed plate 13, but the zone adding device 4 itself rotates the upper tension roll 11 at a speed faster than the speed of the plate 13. It is controlled to rotate at *ITI, and the speed difference is ■
Belt 15. It is buffered by the noise between snoring and day 1716. In addition, the tension roll lO on the entrance side
It is also possible to install a needle adding device 14 to add 41 needles. Of course, in front of the 1-coal device A, there is a heating device for the plate material 13, a rear muffler, and an L-bell for correcting the distortion of the plate material 13 that has been embossed and pressurized.

It is also possible to process the diameter of at least one of the 4an to be slightly smaller than the other, to make the processing strain of the plate material 13 uniform, and to prevent twisting, flatness, burrs, etc. Furthermore, the upper and lower roll groups 3.4 can be formed as shown in FIGS. 4 (al to d) or enlarged in FIG.

Further, FIG. 5 shows an embossing roll 1 in which the cross section of the concavo-convex pattern of adjacent holes and holes is approximately trapezoidal.

〔Effect of the invention〕

As mentioned above, since the split type continuous embossing roll device G according to the present invention is used as the -1-1F split type embossing roll, it is possible to easily form a novel decorative surface combining different patterns. can.
