- the residue material 1311 can be easily divided into two as the trim absorbers 133a and 133c. Further, since the cutting line forming the front end portion of the absorber 23 does not intersect with the cutting line forming the rear end portion, the amount of chips generated when cutting the absorber 23 can be reduced. According to the present embodiment, there are the following effects.
- the cutting device 10 was composed of a cutting mechanism 21, a conveyor 22, and a residue material discharging mechanism 24. Thereby, the cutting device 10 divides the residue material 131, which is obtained by cutting the absorber 23 from the continuous base material 130, into two, and separates the two trim absorbers 133a, 133c. The trim absorbers 133a and 133c are separated from each other. Therefore, the trim absorbers 133a and 133c do not interfere with the tip of the absorber 23. As a result, the absorber 23 is smoothly carried out from the two rollers 64, 66 by the transport conveyor 22, so that the displacement of the absorber 23 can be prevented.
- the repulsive elastic force of the sponge acts when the cutting roller 164 is pressed against the continuous base material 130, so that the cutting blade 65 is formed. Since the pressing force against the continuous base material 130 can be made uniform, the absorber 23 can be cut smoothly.

- the absorber 23 is cut into a shape of the absorber 23 by a cutting blade 65 at a cutting line 29 (FIG. 8A).
- the leading end of the absorber 23 starts to be carried out of the cutting mechanism 21.
- the residue material 1311B that is obtained by cutting the absorber 23 from the continuous base material 130 is drawn in the direction of the arrow 1339.
- the force for pulling out the residue material 131 B acts on the upper end of the tip of the absorber 23 as a fulcrum, so that a crack 32 is generated at the lower end of the tip of the absorber 23 (FIG. 8B).
- the crack 32 tends to spread along the cutting line 29, but the tip of the absorber 23 interferes with the edge of the residue material 131B. For this reason, the tip of the absorber 23 is hooked on the edge of the residue material 131 B, and moves in the direction of arrow 1 39 together with the residue material 131 B (FIGS. 8C and 8C). 8 D).

- the residue material 13 ID is split into two pieces and extracted into trim absorbers 133 a and 133 c.
- the absorber 23D is transported along the continuous direction of the continuous base material 130, so that it is possible to further prevent the front-back, left-right displacement. .
- FIG. 12 shows a continuous base material 130E processed by the cutting apparatus according to the fifth embodiment of the present invention.
- the emboss ratio of the embossing formed on the continuous base material 130E is different from that of the fourth embodiment.
- the side portions 130a and 130c of the continuous base material 130E have a higher emboss ratio than the central portion 130b, and the embossed portion 1306 has a continuous base material 130E. Are formed uniformly along the continuous direction. Therefore, the emboss ratio of the trim absorber becomes higher than the emboss ratio of the absorber 23E.
- the continuous base material 130E is formed by stacking a plurality of f-sheets
- the plurality of sheets can be integrated by enbossing, so that the trim absorber can be reliably pulled out. it can.
- examples of the absorber 23E include rayon, acetate, natural cotton, fibrous polymer absorber, synthetic fiber, pulp, chemical pulp, and a mixture thereof.
- the absorber is preferably a fiber aggregate mainly using rayon having a fiber length in the range of 10 to 51 mm.
- the pitch of the embossed portions 13 6 is preferably in the range of 1 to 9 mm.
- FIG. 13 shows a cutting apparatus 1OF according to a sixth embodiment of the present invention.
- the structure of the residue material discharging mechanism 24F is different from that of the fourth embodiment.
- the residue material 131 F is split into two pieces, trim absorbers 133 a and 133 c, and pulled out.
- the directions of the arrows 135a and 135c are substantially the same as the carry-out direction of the absorber 23D when viewed from the width direction of the absorber 23D, that is, the direction in which they expand in the horizontal direction.
- the absorber 23D since the absorber 23D is not pulled in the thickness direction, the displacement of the absorber 23D can be prevented more reliably.
- the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
- the speed of the line may be about 20 to 200 m / min, and the production rate of the absorber may be about 200 to 2000 Z minutes.
- the tensile strength in the continuous direction of the side portions 130 a and 130 c of the continuous base material 130 on which the trim absorbers 133 a and 133 c are formed may be larger than the tensile strength of the central portion 130b where 23 is formed. This makes it possible to increase the rigidity of the trim absorber while ensuring the flexibility of the absorber 23. In addition, when the trim absorbers 133a and 133c are pulled out, it is possible to prevent the trim absorbers 133a and 133c from breaking.
- the member and the residue material can be reliably separated from each other. Can be prevented.
