摘要： The invention is a method or a device for wrapping the rubber strip around the forming drum while extruding an unvulcanized rubber strip from an injection device, wherein the rubber strip is pressed by a guide roll against the forming drum under tension, as well as a space for absorbing variations in an amount of extrusion of the rubber strip is formed between the guide roll and an extrusion outlet of the injection device, the forming drum is rotated in synchronism with extrusion of the rubber strip so that the guide roll is driven, and the rubber strip guided by the guide roll is wrapped around the forming drum.
