Zusammenfassung: | PURPOSE:To provide a conveyor belt excellent in the bending property over a wide temperature range from a low temperature to a high temperature and capable of surely preventing meandering with a simple structure by covering projections of silicone elastomer formed on one face of the belt with an expansion fabric. CONSTITUTION:Single liquid type room temperature hardening silicone rubber 5 is discharged from a grease gun 4 on the core body 2 side of a resin conveyor belt 3 constituted of cover made of silicon and the core body 3 made of polyester fibers. An expansion fabric 7 using polyurethane fibers for wefts is delivered from a reel 6, a roller 9 with a die is pressed on the expansion fabric 7 by an air cylinder 8, the conveyor belt 3 is moved, and it is left at the room temperature to complete hardening. Projections 10 of silicone elastomer are covered with the expansion fabric 7 to obtain the conveyor belt 3 with meandering preventing projections 10. This conveyor belt 3 is excellent in the bending property, and meandering can be surely prevented. |
