GUIDE ROLLER FOR CONVEYOR BELT
Document Type and Number:
Japanese Patent JP2009126608
Kind Code:
A
Abstract:
To provide a guide roller capable of reducing a change of frictional force and suppressing torsion of a conveyor belt.
A sheet which is separate from a roller body and is a flexible material such as rubber or urethane with ruggedness is adhered in a rib-shape on the surface of a roller. The rib-shaped sheet with ruggedness is spirally adhered. As a result, a friction coefficient with the surface of a conveyor belt is enhanced. This guide roller having this structure is used as at least one of a plurality of (6) circular holding rollers.
