Title:
METHOD OF MANUFACTURING RUBBER ROLLER
Document Type and Number:
Japanese Patent JP2008023816
Kind Code:
A
Abstract:

To provide a method of manufacturing a rubber roller which suppresses the variation of adhesiveness and the occurrence of defects, due to the seizure of the vulcanizing adhesive, and enables efficient production through processes up to the roller-formed product under management for continuous and space- and labor-saving operation.

The method comprises extruding a rubber composition with an extruder while passing a shaft continuously to the cross-head die, in order to form a rubber layer on the shaft. It comprises a process of applying a vulcanizing adhesive to the outer peripheral surface of the shaft, a process of baking the vulcanizing adhesive applied to the shaft with heating mechanisms arranged at least in the upper and lower parts of the shaft-carrying path and a process supplying the shaft having been baked with the vulcanizing adhesive continuously to the cross-head die so as to form a rubber layer on the outer peripheral surface of the shaft, with the processes carried out continuously.
