であつた。 However, conventionally, the formation of grooves in the elastic sheet is
It is formed by scraping the sheet surface with a grinder or milling cutter. However, when forming grooves in this case, the shavings scatter in the form of powder or coarse particles, so the shavings are removed by suction using a vacuum cleaner, but some of the shavings are electrostatically charged on the elastic sheet itself. It remains on the sheet surface due to static electricity, etc. Therefore, when the outer fabric and the lining fabric are sewn to such an elastic sheet, the fabric swells up in the areas where the shavings remain, which significantly impairs the product value.

Make these vertical cutting blades d
The continuous shavings e that have been scraped off are suctioned and removed from the suction conduit f. However, although this device can solve the above-mentioned conventional problems, it has a significantly complicated structure and is expensive, and this tendency increases as the number of grooves increases, and the structure does not allow for easy maintenance and inspection.

粉状になる。 FIG. 1 shows the main structure of the device. In the figure, reference numerals 1 and 1 indicate a pair of groove forming blades that are provided to form two grooves 3, 3 in the surface portion 2a of the elastic sheet 2 while the elastic sheet 2 is being conveyed. The groove forming blades 1, 1 are formed by forming saw teeth on the entire circumference of a cutter or the like of a milling cutter, and are attached to a shaft 10 which is supported between machine frames 8, 8 of the device.
One end of the shaft 10 is connected to a rotating shaft 11, and is driven by a motor to rotate the groove forming blades 1, 1 in a direction (direction of arrow Y) opposite to the direction of conveyance of the elastic sheet 2 (direction of arrow X). The shavings are made to fall in a direction opposite to the conveyance direction of the elastic sheet 2. Further, the groove forming blades 1, 1 have windows 12, 1 of the sheet support plate 4, which will be described later, installed below the groove forming blades 1, 1.
2, grooves 3 can be formed in the elastic sheet 2 being conveyed. Here, the elastic sheet 2 is made of, for example, soft urethane foam, and the shavings produced by the groove forming blades 1, 1 are in the form of granules or powder.

る。 Reference numeral 5 denotes a vibrating rod that strikes the surface portion 2a' of the elastic sheet B having grooves formed on the elastic sheet conveying direction side of the groove forming blade 1 and installed in a direction perpendicular to the conveying direction. This vibration rod 5 is rotatably supported between machine frames 8, 8, and has a hexagonal cross-sectional shape.
The top of the hexagonal shape is brought into contact with the grooved surface portion 2a' of the elastic sheet 13, and the elastic sheet 13 is struck by rotation to cause the shavings to dance. One end of this vibrating rod 5 is connected to a motor drive source (not shown), and an elastic sheet 13
It is set to rotate in the direction opposite to the direction of conveyance.

I try to do that.
次に、前記溝形成刃１，１で溝形成される弾性
シート２に滞積する削り屑の除去方法について説
明する。 Next, a method for removing shavings accumulated on the elastic sheet 2 where grooves are formed by the groove forming blades 1, 1 will be explained.

板４，５間に搬送する。 First, as shown in FIG. 2, the groove forming blades 1, 1, the vibrating rod 5, and the static electricity remover 7 are operated. Further, as shown in FIG. 3, the elastic sheet 2 is conveyed between sheet support plates 4 and 5.

まう。 In this case, due to the formation of the grooves 3, a large amount of shavings are deposited on the elastic sheet 2 (especially on the lower side of the groove forming blade 1).
However, the groove forming blade 1 is scattered by the cover 7.
, most of the shavings are sucked into the suction device through the suction port 7a of the cover 7. However, due to static electricity, the elastic sheet 2
The shavings adsorbed on the top cannot be reliably sucked off by the suction force of the suction device alone. Therefore, some of the shavings are on the surface portion 2a of the elastic sheet 2.
It flows in the direction of conveyance of the elastic sheet 2 while remaining on the surface. For this reason, a static electricity removing device 6 is provided on the back side of the elastic sheet 13 in which the grooves 3 are formed, so that the adhesion force between the shavings and the elastic sheet 13 is removed, and the scraps are sucked out from the suction port 7a of the cover 7 by a suction device. However, even with this, a very small amount of shavings flows together with the elastic sheet 13 in the conveyance direction.

３に削り屑が残らなかつた。 Therefore, in order to ensure that even the slightest amount of shavings could be sucked up with a suction device,
The sheet 13 is placed on the surface portion 2a side of the elastic sheet 13.
A vibrating rod 5 is provided to make the shavings dance due to a synergistic effect with the static electricity removing device 6, and the shavings are then sucked up by a suction device from the suction port 7a of the cover 7. In this way, the shavings are removed from the elastic sheet 13 in which the grooves are formed, so that they are reliably sucked up by the suction device.
No shavings were left on 3.

い。 In the above embodiments, the vibrating rod 5 has a hexagonal cross-sectional shape, but the present invention is not limited to this. Alternatively, it may be a rod that vibrates by striking the groove-formed elastic sheet 13 through eccentric rotation.

といつた問題を一掃することができる。(Effects of the Invention) As explained above, according to the method and device for removing shavings from an elastic sheet formed with grooves according to the present invention, shavings remaining on an elastic sheet formed with grooves are sucked by a suction device. However, the shavings that still remain on the elastic sheet due to static electricity etc. are made to dance by the synergistic action of the static electricity remover and the vibrating rod, and the shavings on the grooved elastic sheet are removed by the suction device. No scraps remain on the grooved elastic sheet being conveyed. Therefore, even when the outer material and the lining material are overlapped and sewn onto a grooved elastic sheet, the areas where residual shavings remain, which was a problem in the conventional method, bulge out in a convex shape, significantly reducing the product value. It is possible to eliminate such problems.

Furthermore, it can be easily installed in a device that forms grooves in elastic sheets using a milling cutter, and has extremely useful effects in practical use.
