1 to 5 show one embodiment of the present invention, in which a first roller 1 which is rotatably fixed and a second roller 2 which is pressed against the first roller 1 by a pressing means 3 are shown. Together with forming a pinch roller mechanism, an uneven pattern 5 is formed on the peripheral surfaces of the rollers 1 and 2, and the sheet 6 is passed between the rollers 1 and 2 to give the sheet 6 unevenness. It was done like this. In the embodiment, the concavo-convex pattern 5 formed on the peripheral surfaces of the rollers 1 and 2 is a twill-shaped concavo-convex pattern as shown in FIG. 5a and right spiral thread groove 5
By forming b, the pyramidal protrusions and recesses are formed at equal intervals in both spiral screw grooves 5a and 5b that intersect each other (orthogonally in the embodiment). FIG. 5 (b) linearly shows the meshing condition of the concavo-convex pattern 5 of both rollers 1 and 2, and the twill-like concavities and convexities are imparted to the sheet-like body 6 by passing between the rollers 1 and 2. It

The main body 10 is composed of a side wall consisting of a pair of side pillars 11, a lower plate 14 and an upper plate 15, and four connecting rods 16 for connecting both side walls. The stands 12 and 13 are slidably fitted (rail structure) between the side columns 11. The lower first roller 1 is fixedly attached by its own weight, and the upper second roller 2 is pressed against the first roller 1 by pressing means 3. The pressing means 3 is composed of a coil spring 17 and a pressure adjusting knob 18 for adjusting the pressing pressure, and the pressure adjusting knob 18 is screwed into a screw hole of the upper plate 15 of the main body 10, By rotating the knob portion, the pressing pressure can be adjusted according to the hardness and thickness of the sheet-like body 6. In addition, when the second roller 2 is made of iron, since it has its own weight, the coil spring 17 may not be necessary. Further, the second roller 2 is biased in a direction of pushing it up (the coil spring is arranged on the lower side). It may be better to adjust the pressure by doing In this case, the pressure adjusting knob 18 acts as a regulation means for the upward movement of the second roller 2.

On the other hand, in the embodiment, the driving means for rotating the first roller 1 is formed by the manual handle 19, but it goes without saying that it may be driven by a motor. Further, without providing any special driving means, the peripheral surface of the second roller 2 is manually rotated to feed the sheet-shaped body 6 between the rollers 1 and 2 from the inlet side and the sheet-shaped body 6 from the outlet side. Both rollers 1 and 2 may be driven by pulling.
When the sheet-like body 6 is relatively thin and soft, no driving means is required.

The operation of the embodiment will be described below. Now, the concavo-convex pattern 5 of both rollers 1 and 2 forming the pinch roller mechanism will be meshed as shown in FIG. By passing the sheet-shaped body 6 through the sheet-shaped body 6 as shown in FIG. At this time, if the height (depth) of the convex portion (concave portion) is increased, large unevenness can be provided. Furthermore, if the tip of the convex portion is left sharp, it is possible to make a hole in the tip, and the sheet-like body 6 is used as waste paper such as newspaper or copy paper (may be a stack of several sheets), In the case where the wiping effect is to be obtained by imparting unevenness, the liquid absorption effect in the hole cross section can be further improved. on the other hand,
If the tip of the convex portion is rounded, a smooth concave-convex pattern is formed, but even in this case, the fibers of the paper are moderately loosened and the absorption effect is improved.

As described above, in the present embodiment, by turning the manual handle 19, it is possible to easily form a twill-shaped unevenness suitable for wiping off waste water, waste oil, etc. on waste paper such as newspaper, copy paper, etc. It can be added and promotes effective use of waste paper for wiping sewage, waste oil, etc., and can be said to be extremely useful from the viewpoint of recycling.

The concavo-convex imparting apparatus of the present invention can also be used to effectively utilize a sheet-like waste material such as a cardboard, a thin metal plate, a resin plate or the like as a decorative plate, etc. When it is desired to give a decorative effect by applying the sheet-like member 6 between the rollers 1 and 2, as in the case of the waste paper, the unevenness can be easily provided. In this case, it goes without saying that the pressure of the pressing means 3 needs to be appropriately adjusted according to the hardness and thickness of the sheet-shaped body 6.

Furthermore, the unevenness imparting device of the present invention can also be used as a processing device for softening a sheet-like food product (dried fish, chicken, meat, etc.).
That is, when the sheet-shaped food is passed between the rollers 1 and 2, when the unevenness is imparted to the sheet-shaped food, the bones are broken or the fiber is loosened, and the food can be easily processed into an easy-to-eat state. Become.
