Production method for annular rubber sleeve

The invention discloses a production method for an annular rubber sleeve, and belongs to the technical field of tooth-shaped rubber sleeves. The method comprises the following steps: forming rubber sleeve sheets: placing a rubber sheet blank on a lower die, placing groove forming blocks at the tops of the two ends of the rubber sheet blank, and pressing the rubber sheet blank to form the rubber sleeve sheets with notches; splicing the rubber sleeve sheets: adjacently splicing the two rubber sleeve sheets to enable the notches in the two sides of the rubber sleeve sheets to be oppositely attached to form a connecting groove, and placing a connecting rubber block in the connecting groove; and conducting annular splicing: winding the two ends of the rubber sleeve sheets which are spliced in sequence into an annular structure, then splicing the edges of the two sides of the rubber sleeve sheets, placing a connecting rubber block in the connecting groove, and forming the annular rubber sleeve after compression mol
