ABSTRACT:
A winding mechanism for winding a narrower web has a drive shaft with a torque transmitting member fixedly mounted thereon, and a holder rotatably mounted on the drive shaft with a spring disposed around an outer circumferential surface of the holder with cushioning members interposed therebetween. Stoppers are disposed respectively in three chambers defined in the holder. A groove is defined in an inner circumferential surface of a winding core around which the narrower web is wound, and the cushioning members are fitted in the groove. A pressing force of the spring is applied through the stoppers to the winding core which is mounted on the holder.
