Patent ID: 8662874

Claim:
An apparatus for producing a cogged belt for conveying articles or for power transmission, the apparatus comprising: a pulley ( 2 ) activatable in rotation by actuator organs, peripherally forming a cogged profile ( 40 ); two lateral edges ( 3 , 4 ) fixed respectively to opposite heads of the pulley ( 2 ) for laterally delimiting spaces ( 11 , 11 A, 11 B) identified by the cogged profile ( 40 ); a mobile contrast belt ( 5 ) having a tract ( 35 ) facing a circular sector of the pulley ( 2 ), identifying in combination with the pulley ( 2 ) and with the lateral edges ( 3 , 4 ) a channel ( 12 ) in which an inlet section (A) and an outlet section (B) are formed, in relation to an advancement direction (K) of the pulley ( 2 ); a belt dispenser ( 7 ) for supplying a prefabricated belt ( 8 ) internally of the channel ( 12 ) via the inlet section (A), the prefabricated belt being a textile or a large mesh net, with the prefabricated belt ( 8 ) being gripped between the contrast belt ( 5 ) and the external contact profiles ( 45 , 46 , 25 ) of the pulley ( 2 ) or the lateral edges ( 3 , 4 ), the prefabricated belt being drawn along the channel ( 12 ) by rotation of the pulley ( 2 ) together with the mobile contrast belt; and, a molten material dispenser ( 6 ) for supplying molten thermoplastic or heat-hardening material into the spaces ( 11 , 11 A, 11 B) of the pulley ( 2 ) in the channel ( 12 ) upstream of the entry of the prefabricated belt therein in a sufficient measure to fill the delimited spaces of the pulley which identify the cogged profile and to produce at the inlet section a mutual-contact between the molten thermoplastic or heat-hardening material contained therein and the prefabricated belt ( 8 ) for enabling formation of the cogged belt as a single body ( 30 , 50 ) within the channel, the cogged belt comprising the prefabricated belt ( 8 ) and a covering ( 26 ) constituted by the solidified thermoplastic or heat-hardening material, the thermoplastic or heat-hardenable material solidified prior to exit of the unitary cogged belt from the channel outlet section.
