Abstract
PURPOSE: To enable dimeter and width of a drum to be reduced in size by using a single device, by varying rotary phase of 2 axes of the drum having a rotary axis consisting of 2 axes on its center.
CONSTITUTION: A drum A, which is provided with a rotary axis B on the axial core and forms a green tire in the surrounding area, is composed by 4 parirs of front split pieces 1 and rear split pieces 2. Inside these front split pieces and rear split pieces, a front-center member 4 and a rear-center memeber 4', which hold the split pieces and move these split pieces into the direction of the drum diameter by operations of No.1WNo.3 links 6, 10 and 13, are installed so as to form pairs with the split pieces. The front and rear center members are provided with respective fixed guides 22, 23, 22' and 23' between the front and rear split pieces, and the split pieces are made possible to slide in the axial direction toward the center member. The both center members pivoted with a pin 9 are constituted in a free-to-bend arrangement.
