PURPOSE:To avoid a material to be machined from being inclined in the running direction by disposing several pairs of guide rolls on the inner surfaces of both end edges of a material feed belt that project over a driving roll and a driven roll, and detachably attaching a stopper for the material to be machined per each pair of guide rolls. CONSTITUTION:In a sander having an endless material feed belt 8 disposed corresponding to a sanding portion 23, a driving roll 5 and a driven roll 4 which have the same width as that of a material feed table 3 are provided in front and rear of the table 3, and a material feed belt 8 having such a width as to project both end edges thereof over the rolls 4, 5 is stretched between the rolls 4, 5. Several pairs of guide rolls 12 running in contact with the end surfaces of the respective rolls and both sides of the material feed table 3 are disposed on the inner surfaces of both end edges of the belt 8 that project over the rolls 4, 5, and the end portion of a stopper 26 for a machined material, which crosses over the material feed belt 8 in the lateral direction is detachably mounted on every pair of guide rolls 12. Accordingly, a material to be machined can be avoided from being inclined in the running direction. |
