Abstract
Abstract An apparatus for end correction of an automotive tire strip member comprises a conveyor belt for conveyance of a tire strip member consisting of rubberized steel cords to a tire building drum, which conveyor belt is narrower than the strip member, a supporting plate disposed under the conveyor belt and adapted to support the belt, a guide plate extending in parallel with the lengthwise axis of the conveyor belt and disposed above the supporting plate and on one side thereof in such a manner that it is driven to advance and retreat with respect to the conveyor belt, and a magnet disposed below the supporting plate and toward one side thereof in such a manner that it is driven to advance and retreat with respect to the conveyor belt.

An apparatus for end correction of an automotive tire strip member comprising a conveyor belt for conveyance of a tire strip member consisting of rubberized steel cords to a tire building drum, said strip member having an end which is beveled, said conveyor belt being narrower than said strip member, a supporting plate disposed under said conveyor belt and adapted to support said belt, a guide plate extending in parallel with the lengthwise axis of said conveyor belt and disposed above said supporting plate and on one side thereof in such a manner that it can be driven to advance and retreat in the breadthwise direction of said conveyor belt, and a magnet disposed below said supporting plate and toward one side thereof in such a manner that it is driven to advance and retreat in the breadthwise direction of said conveyor belt, said magnet being substantially elongated in the lengthwise direction of said conveyor belt, the dimension of said magnet in said lengthwise direction and the dimension of said guide plate in said lengthwise direction each being at least substantially equal to the entire length of said beveled end of said strip member, said magnet and said guide plate being in substantial registry with each other in said lengthwise direction, and means for stopping the conveyor belt when the lengthwise edge of said beveled end is in substantial registry with said magnet and said guide plate in said lengthwise direction, and driving said guide plate advancingly in the breadthwise direction of said conveyor belt into abutment against a portion of said lengthwise edge of said beveled end on the stationary conveyor belt and then driving said magnet retreatingly in the breadthwise direction of said stationary conveyor belt to a position adjacent said guide plate thereby to pull the remainder of said lengthwise edge of said beveled end into abutment against said guide plate so that the entire lengthwise edge of said beveled end abuts against said guide plate and for then driving the conveyor belt again.
