着するようにツる。The unvulcanized rubber seam 1-11 is attached to the forming belt 12.
When the forming bells 1 to 12 are transferred into the forming tube 15 in a straight line, the forming bells 1 to 12 are deformed into a circular shape along the inner wall of the forming tube 15 and move forward. : The rubber seams 1 to 11 pass through the molded tube 15 to form a core Q'llll 13.
The spring is placed along with the A-ming bells 1 to 12, and wound onto the core shaft 13. The forming tube 15 has an inner diameter approximately equal to the outer diameter of the roller to be manufactured, which is equal to the thickness of the forming belt 12, but when passing through the core shaft 13 and the rubber seams 1 to 11, Use one that is designed to apply tightening pressure. After the core shaft 13 and the rubber sheet 11 have passed through the forming tube 15, they are sent to a well-known vulcanizer (51 (shown in the figure)) and the rubber sheet 1- is cured and bonded to the core shaft 13. It's like that.
