[Problem to be Solved by the Invention] In the wide belt sander machine 1 having the basic configuration described above, the endless sanding belt 15 of the metal treading pad 14 rubs the treading surface by continuing the polishing process.
The temperature easily rises due to frictional heat, which causes thermal strain, and warpage occurs due to the difference in linear expansion caused by the shape of the front and back sides as shown by the chain line in FIG. This warp causes a large drop between the end and the center. The longitudinal drop of the tread surface has a large effect on the ground surface, and the tread pad
No. 14 does not step on the work material in a planar manner, the work material surface is deeply ground at the center portion, and the end portion is ground shallowly or cannot be ground at all, resulting in uneven grinding and polishing.

The treading pad 20 is fed to the sanding frame 18 of the grinding head 10 by screwing screws 19 into screw holes 24 provided on both side edges of the treading pad 20 at appropriate intervals. It is arranged inside the passage-side traveling portion. On the upper surface of the treading pad 20, a plurality of partition grooves 25 according to the main part of the present invention are formed at appropriate intervals along the width direction. The partitioning groove 25 substantially divides the treading pad 20 along its longitudinal direction, and divides the treading pad 20 into portions.

By the way, the metal tread pad 20 is liable to become hot due to frictional heat due to the endless sanding belt 15 rubbing due to the continuation of the polishing process, so that thermal expansion occurs, and the metal treading pad 20 becomes longer due to the difference in linear expansion caused by the front and back shapes thereof. Heat distortion occurs in the scale direction. In the conventional configuration, warping occurs in the longitudinal direction due to the linear expansion. By the way, as described above, on the upper surface of the treading pad 20, as shown in FIG. 2 to FIG. 4, partition grooves 25 having a depth vertically extending the treading pad 20 by half or more from above are formed at appropriate intervals. Have been. For this reason, even when the treading pad 20 is heated to a high temperature by frictional heat generated on the treading surface 22 and generates thermal strain in the longitudinal direction, each thermal strain is divided by the partitioning groove 25 and the partitioning groove 25 is formed. , 25, the thermal strain is discontinuous, and the thermal strain is absorbed by each partition groove, and the thermal strain or the step due to the thermal strain does not overlap at the end, thereby preventing the warpage as a whole.

Thus, the partition groove 25 prevents the adverse effect of the high pressure of the tread pad 20 as much as possible, the tread surface 22 is kept as horizontal as possible, and the work material w is ground and polished evenly on the upper surface. The Rukoto. In this configuration, the partition groove 25 is formed at right angles to the longitudinal direction in the width direction on the upper surface of the treading pad 20, but it may be formed to be inclined. In addition, various forms of forming the partition groove 25 are conceivable.

[Effects of the invention] In the present invention, as described in the above description, the partitioning grooves 25 in the width direction are formed at appropriate intervals on the upper surface of the treading pad 20. Even if it occurs, the tread pad 20 is substantially divided in the longitudinal direction by the partition grooves 25, and expands and contracts independently between the partition grooves 25, 25. The distortion does not overlap at the end of the treading pad 20 or the like. Therefore, warping due to thermal expansion and contraction of the treading surface 22 of the treading pad 20 is unlikely to occur, and as smooth a surface as possible is maintained.
There is an excellent effect that a good pressing and grinding can be performed by pressing the upper surface of the substrate flatly.
