DEVICE FOR WINDING FRAMES OF PNEUMATIC TYRE CASE Russian patent published in 1994 - IPC

FIELD: tyre industry equipment. SUBSTANCE: grooves "a" opened on the side of a coil to receive chain 4 with profiles matching the profile of the cross section of bush-roller chain 4 are made in a guide. Brackets are reciprocally mounted and have straps for fixing rotary members. This allows tension of chain 4 to be controlled so as to provide minimum draw force when it moves along the guide, and on the other hand the slack is taken up so as to exclude angular displacements of chain 4 on the sections outside grooves "a" when the brackets are loosened. EFFECT: improved quality. 4 dwg
