ABSTRACT:
Belt (1) of flexible polymeric material, in particular an elastomeric material, for the transmission of motion between two pulleys (6), comprising at least one longitudinal slot (2) defined by a bottom (3) and two lateral walls (4, 5). The belt passes from a first position in which the walls (4, 5) of the slot (2) are at a certain distance from the opposite lateral surfaces of the pulley, to a successive position during the winding of the belt around the pulleys, whereby the pull exercised on the inextensible reinforcing elements (7) of the belt leads to the approach of the slot walls to the opposite lateral surfaces of the pulley (6), resulting in the transmission of motion through friction.
