Producing method of rubber strip winding body, and rubber strip winding apparatus

摘要

An unvulcanized rubber strip ( 3 ) is supplied to an outer peripheral surface of a rotating cylindrical body ( 4 ) from a sending-out roller ( 16 ) which laterally moves in an axial direction of the cylindrical body ( 4 ), thereby spirally winding the rubber strip ( 3 ) to form a winding body ( 5 ). In a tilting reference plane ( 29 ) defined as a plane which is in parallel to a plane ( 4 S) passing through an axis ( 4 i) of the cylindrical body ( 4 ) and which passes through an axis ( 16 i) of the sending-out roller ( 16 ), the sending-out roller ( 16 ) is held such that the sending-out roller ( 16 ) can tilt positively and negatively within an inclination angle (alpha) of 0 to 45° with respect to a tilting reference line (N) which is parallel to the axis ( 4 i) of the cylindrical body ( 4 ). The sending-out roller ( 16 ) is laterally moved while changing the inclination angle (alpha).
