ABSTRACT:
An apparatus for making V-belts comprising a base member, a cover for the base member, a channel-like guide means carried by the base member for receiving a length of belting from a supply, first slot means cooperating with said guide means for receiving and guiding a cutting means to cut a predetermined length of said belting required to form a closed loop of said belting, second slot means cooperating with said guide means for receiving and guiding a cutting means in making a slot in each free end of said belting for receiving a web-like splice element adapted to bridge the free ends of said predetermined length of belting to form said loop, and heating means carried by said apparatus for vulcanizing the free ends of the predetermined length of belting to form a splice between the free ends of the belting. The method which comprises cutting a predetermined length of belting from a supply of V-belting, forming a slot in each free end of the predetermined length of belting, positioning a web-like splice element in bridging relation to said free ends, and vulcanizing said free ends and said splice element whereby to provide a strong and secure spliced joint between said free ends. In the preferred embodiment, a reinforcing strap made of a suitable material such as nylon is secured to the outer surface of the two free ends in bridging relation thereto by fastening means which pass into the belting and through the one or more splice elements.
