Abstract

"NEW PULLEY FOR TRANSPORT OF ABRASIVE BANDS SINFIN", characterized by a central metallic core provided with means for its assembly on the axis of the sanding machine, whose core has on its circular surface a finished number of axial slots whose internal emptying is of a magnitude greater than its communication opening with the outside, in each of whose grooves is inserted, in an axial direction, the rivet or terminal that completes the piece guide profile, of appropriate flexible material, the rest of whose profile is delimited two parallel curved lines, the inner one, which adjoins the outer perimeter of the core, and the outer one, which forms part of the retaining and transport surface of the endless band that embraces it, this being the resting position but, when the The pulley rotates at high speed, even when said nipples or terminals are retained in the axial grooves of the core, the rest of the pieces of flexible material go They tend to move away from the surface of the latter or tend to deviate by virtue of the centrifugal force causing an increase in the diameter of the pulley that stretches the endless abrasive belt, which, depending on its development, prevents or partially restrains the deformation of said flexible parts. in the angular zone that embraces but always increasing the link between the repeated endless belt and pulley.
