<p>The invention relates to a device for rolling up a flexible strap which eliminates the risks of wearing out and breaking the flexible straps. Said device (10) comprises a base (11) which supports a rotary pulley (12) on which a flexible strap segment is rolled up. Said pulley is mounted on a shaft (13) actuated by an electric motor (14) using a reduction gear (15). The rotary pulley (12) is provided with two parallel peripheral grooves (16, 17) separated by a fixed belt (18) having a loop-dividing member (20). The belt (18) has the function of guiding the flexible strap and separating the two loops inserted into the two parallel peripheral grooves (16, 17), respectively. For this purpose, the loop-dividing member (20) comprises an oblique central recess (21) arranged so as to guide the flexible strap from the outlet of one of the peripheral grooves to the inlet of the other peripheral groove.</p> |
