ABSTRACT OF THE DISCLOSURE TRANSFER ROLL SYSTEM A transfer roll for transferring a strip com- ponent from a conveyor to a tire building drum has an outer rim member rotatably mounted on a cylindrical ring member which is mounted on an inner hub for movement relative to the tire building drum. A pair of piston- cylinder assemblies control the movement of the cylindri- cal ring member to press the outer rim member against the strip component on a tire building drum. The outer rim member is rotated by a motor mounted for movement with the cylindrical ring member and the amount of rotation is controlled by control means including an encoder mounted for movement with the cylindrical ring member and in engagement with the outer rim member. A pair of the transfer rolls may be mounted on a shaft with means for adjusting the distance between the rolls after the strip components are transferred from the conveyor to the rolls in a conveyor position and moved to an intermediate adjusting position. Several sets of vacuum cups are pro- vided around the circumference of the transfer rolls and each set has a separate vacuum pump to retain the strip component on the outer rim member.
