[Problems to be solved by the invention]
However, in such a conventional molding apparatus, when joining the non-cut edges of the cut pieces to each other, it is necessary to perform the operation while pressing a pair of joining rollers from the upper and lower surfaces of the joint portion of the cut pieces. Therefore, in order to arrange this bonding apparatus, it was necessary to divide the transport conveyor into two parts.
[0005]
However, when the conveyor is divided into two, a gap is generated between the divided conveyors, and the non-cut edges of the cut pieces having no rigidity in the longitudinal direction fall into the gaps, and the non-cut edges are bonded. However, there is a problem that it is difficult to automate the joining of the band-shaped materials.

The third and subsequent cut pieces are conveyed by the take-up conveyor to the forming drum side by a predetermined distance, and the cut pieces are conveyed to the forming drum side via the conveying means in the same manner as the second cut pieces. The gist is to sequentially transfer the non-cut edge portions of the cut pieces to the predetermined position on the upper side, and to join the non-cut edge portions of the cut pieces sequentially to form a length of one tire.
[0008]

At the connection between the conveyor and the take-up conveyor, a bonding device for joining the non-cut edges of the cut pieces of the band-shaped material is installed, between the feed conveyor and the transfer conveyor, and between the feed conveyor and the take-up conveyor. In the meantime, it is the gist that transport means for sucking, holding, and transferring the cut pieces of the cut strip-shaped material are provided.
[0011]
Here, the laminating apparatus is configured by a pair of upper and lower rotatable pulling rollers that reciprocate in a direction orthogonal to the conveying direction of the belt-shaped material at a connecting portion between the conveying conveyor and the take-up conveyor.
[0012]
In this way, the transport conveyor and the forward or reverse reversible take-up conveyor directly connected to the forming drum are arranged in series in a direction orthogonal to the feed conveyor, and further, at the connection between the transport conveyor and the take-up conveyor, a belt-shaped material is provided. A laminating device for joining the non-cut edges of the cut pieces of the cut piece is installed, and between the feed conveyor and the transport conveyor, and between the feed conveyor and the take-up conveyor, the cut pieces of the cut band-shaped material are cut.
