Claims

[Scope of Claim for Utility Model Registration] A fabric end folding mechanism of a circular rubber sewing device that sews a circular rubber fitted on the outside of a circularly shaped fabric together with a folded part folded back to the outside of the fabric. A movable frame that is reciprocated outside a fixed frame that holds the fabric in an annular shape is provided with a hook portion that can hold and release an end of the fabric that has been held in an annular shape by the fixed frame; A cloth end folding mechanism for an annular rubber sewing device, comprising: a drive mechanism for moving a portion toward and away from the fixed frame.
