Device for folding body ply

摘要

To provide a turn-up device which is capable of turning up both width-end portions of a body ply by an even pressing force without leaving any spaces in the circumference even in the case of being high in turn-up height. To this end, a plurality of arm components 23 are circumferentially arranged to be movable in the axial direction of an operating shaft 11 and to be pivotable radially of the operating shaft; guide members 39 are respectively supported at both sides on an end portion of each arm component to be rotatable about an axis parallel to a pivot axis of each arm component; coil springs 41 are interposed in respective spaces each between two guide members respectively supported on the arm components adjoining; both end portions of the coil springs are respectively connected to the guide members; pressing members 43 which supplementarily cover respective spaces between the coil springs are rotatably supported on the arm components ahead of or behind the coil springs; and at least the outer surfaces of the coil springs are covered with elastic members 42 which are rich in elasticity.
