An object of the present invention is to provide a tread centering device which automatically detects the position of tread center and holds it in a straight form even when the center of tread is not positioned in a straight form. The device mainly comprises a plurality of detectors for detecting a groove for centering the tread, a holding plate which is inserted into the detected groove, and a mechanism which moves said holding plate transversely to align said groove in a straight form.

A guide mechanism consisting of guide plates and guide rods and a reciprocating mechanism consisting of a fluid cylinder are disposed on a machine frame capable of coming close to and away from a building drum through a fluid cylinder and disposed in such a manner as to keep a slight gap between a support surface of a material and a drum surface when it comes close to the building drum. A moving member capable of reciprocation toward and away from the building drum is disposed in the reciprocating mechanism. A material support plate extending toward the building drum and a support member consisting of leaf springs urging and separating the material between them and the material support plate through a material push mechanism are disposed on the moving member. A cutting guide member is disposed at the tip of the machine frame in a fashion such that its tip projects from the tip of the material support plate when the material support plate moves back. When the material support plate moves back, the tire constituent material can be cut along the tip of the cutting guide plate, and when the material support plate moves forward on the drum, the tip of the tire consituent material projects by a distance l from the tip of the material support plate, and the material can be pressed to tack to the drum by manually pushing the projecting portion of the surface of the drum.
