Publication number: 20040144626Abstract: A joining line from a portion of a belt caught and held between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is a single straight line or a gentle curve having a large angle with respect to a tangent to a belt peripheral line. The joint of the other part of the belt is made by a finger joint. Alternately, a joining part from a portion of a belt caught and hold between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is made with a finger joint with widely pitched fingers, while another joining part of the rest of the belt are made with a finger joint with narrowly pitched fingers. Peeling or breakage at the joining parts for a long time, and a thick joining part are eliminated. And low cost production is achieved.Type: ApplicationFiled: November 11, 2003Publication date: July 29, 2004Inventor: Naoyuki Saeki

Publication number: 20030192768Abstract: A conveyor belt with advertising is fabricated by coating at least one flexible belting member with a vinyl size coating. A white base coat is applied over the vinyl size coating. A variety of printing processes may be used to print registered color separation images on the belting member. These processes include silkscreen, flexographic and offset printing. The belting members may be made in lengths shorter than the entire length of the conveyor belt with removable attachment means, permitting individual advertising images to be replaced without replacing the entire conveyor belt. Methods for fabricating the belting members including ink formulations, handling and drying steps are also described.Type: ApplicationFiled: June 6, 2003Publication date: October 16, 2003Inventors: Joseph J.
