PROCESS AND APPARATUS TO APPLY IDENTIFICATION INSCRIPTIONS ON SLEEVES MADE OF ELASTOMERIC MATERIAL IN THE MANUFACTURE OF DRIVING BELTS

摘要

A sleeve (4) is fitted on a supporting table (3) to be positioned in front of a storage device (42) carrying a plurality of rolls (27) of first ribbon-like manufactured articles (25) contained in respective boxes (43) and each having a transferable film (30) bearing identification inscriptions thereon, applied to a paper substrate (29). One of said manufactured articles (25) is unfolded and longitudinally extended on the sleeve (4) by a first grasping member (55) in order to be then cut by a cutting member (68) acting close to the box. A heated presser roller (32) longitudinally movable on the ribbon-like-manufactured article (25) causes the transferring of the film (30) to the sleeve (4). Simultaneously, the application of the film (30) belonging to a second ribbon-like manufactured article (26) is carried out, said second manufactured article (26) being supported by a main carriage (33) carrying the presser roller (32) and engaging with a positioning roller (73) unfolding the manufactured article on the sleeve (4) before the presser roller (32).
