The device comprises at least one module for stitching the tread and a means for moving the module vertically and horizontally. The stitching module comprises a frame which is provided with a fixed stitching assembly, equipped with spikes, and at least one mobile stitching assembly. The at least one mobile stitching assembly comprises at least one stitching plate provided at the base of same with at least one planar horizontal contact surface, from which at least two spikes protrude. The plate is arranged in a vertical guide space provided in the frame such that the spikes protrude downwards and such that it is free to move vertically in this space over a limited travel path. The device also includes a vertical movement device for moving the plate from the top downwards in this guide space and a device for locking the altitude position of the plate in this space.

A manufacturing method for manufacturing a sheet-like belt 8b from a master roll first and then forming a cylindrical belt by winding the sheet-like belt 8b around a molding drum includes measuring a length of the sheet-like belt 8b, and making a pass of fail determination as to the length of the sheet-like belt 8b. The sheet-like belt 8b is wound around a winding cylinder 50 and transported to a place for lamination to the molding drum only when a pass determination is made in the step of making a pass or fail determination as to the length of the sheet-like belt 8b.

A device for supplying a tire-constituting member includes a placement portion to which a tire-constituting member is supplied from the rear side to be placed on the placement portion, a first holding device to hold the tire-constituting member front end portion and is movable, a second holding device to hold the tire-constituting member rear end portion cut to a predetermined length and is movable, a detection device to detect the front end portion position placed on the placement portion, and a control unit which calculates deviation amounts with respect to preset reference positions of the front end portion according to data from the detection device and drives the first holding device in a state where the rear end portion is held by the second holding device such that the front end portion is positioned at the reference position according to the calculation results.
