FIELD: woodworking industry.SUBSTANCE: conveying roller (1) conveys the workpiece (2) on the support (3) in the direction of feeding (5) using the teeth (6) distributed on the circumference. On the lower side of the workpiece the moving is supported through the table roller (4). The teeth have the main tooth (7) and an additional tooth (9) located at a distance from it. The main and the additional teeth are interconnected by the contact area (8). The main tooth is bounded by two flat side surfaces (11, 12) which intersect in the apex (7') located on the radius (r1). The additional tooth has two flat side surfaces (13, 14) which converge in the apex (9') located on the radius (r2). The radius (r1) is larger than the radius (r2). The contact area is on the radius (ra) which is smaller than the radii (r1), (r2). The side surface (14) limits the receiving box for the chips (10), having a base (15). The side surfaces (12, 13) limit the receiving box for the chips (10a).EFFECT: reduced wear of the teeth.11 cl, 11 dwg |
