  • Patent number: 6024817
    Abstract: A belt-shaped member cut into a predetermined length is fed from a feeding devices to a tire forming drum and is wound on its cylindrical peripheral surface. Center portions of the opposite ends of the belt-shaped member are pushed to be joined to each other and the side portions of at least one of the opposite ends of the belt-shaped member are held by upper and lower holding pawls. Such holding pawls are swung along an arcuate path so that both side portions of the opposite ends of the belt-shaped member are drawn near each other to abut against each other. The abutting end portions are pushed toward the peripheral surface of the drum by pushing devices for joining them together.

  • Patent number: 5292398
    Abstract: An apparatus joins opposite ends of a tread on a rotary drum in a tire making machine. Besides the rotary drum, the apparatus includes a conveyor having two lateral endless loops and a guide in the form of rollers interposed between the loops. The conveyor is disposed upstream of the rotary drum. Clamping mechanisms are provided to clamp the respective sides of the tread at a rear end thereof to the endless loops of the conveyor, respectively. A tread placed on the endless loops of the conveyor is maintained in relative position by the guide. The actual length of the tread on the conveyor is measured. The front end of the tread is adhered to the rotary drum and the opposite sides of the tread at the rear end thereof are clamped to the conveyor. The conveyor and drum are then driven at appropriate speeds based on the length of the tread to cause the ends thereof to be joined on the drum. Movable grippers can be provided to stretch the rear end of the tread at the sides thereof into abutment with the front end.
