Abstract: A tire building system, which does not require prolonging tact time for tire building, specific occupying space for endless circulative traveling of a building carriage, and increasing noises and vibrations, and which is free from possibility of premature deterioration of carriage positioning accuracy. The system includes workstations configured to mount applicable tire components onto a building drum, respectively; a building carriage configured to support the building drum to thereby move the building drum among the respective workstations; and carriage guiding means for guiding a movement of the building carriage on a predetermined path. The carriage guiding means includes two inner and outer endless rails, and wheels provided on the building carriage, the wheels each being configured to roll on opposite side surfaces of associated one of the endless rails to thereby restrict a carriage position in a direction orthogonal to an extending direction of the endless rails. The endless rails are each configured with a straight portion and an arcuate portion which are smoothly continued to each other, and the arcuate portion has a rail width W narrower than a rail width of the straight portion.

Abstract: METHOD OF FORMING PLY MEMBER A method of forming a ply member such as a carcass ply for a radial tire. The ply member is formed a plurality of belt-shaped members having a width obtained by multiplying .pi. inches by an integral number (1, 2, 3, ...) and a constant length. These belt-shaped members are successively attached one by one onto a forming drum having an outer circumferential length obtained by multiplying .pi. inches by an integral number so that the side edges of the belt-shaped members are arranged in parallel with the axis of the forming drum. The adjacent side edges of the belt-shaped members in circumferential directions of the forming drum are forced closer together to butt-join the faces of the side edges with each other. In case that the forming drum is a polygonal cylindrical forming drum whose one side of the polygon has a length obtained by multiplying .pi. inches by an integral number, the belt-shaped members are more easily attached to the forming drum.

Abstract: Un metodo y un dispositivo para hacer virar de manera controlada bajo una guia de carriles (31) y (32), un carro en las porciones curvas (31a) y (32a) de una ruta de movimiento sin fin del tipo ovalado (5) para simplificar la estructura de un dispositivo y hacer disminuir los costos de equipo y costos de funcionamiento. El carro colocado sobre el lado del suelo se acopla a un soporte (37) conducido o accionado a lo largo de las porciones curvas (31a) y (32a), y el carro es remolcado por el soporte (37) para hacer correr este sobre toda la longitud de las porciones curvas.

Abstract: A method and a device for drivingly turning, under the guide of rails (31) and (32), a carriage in the curved portions (31a) and (32a) of an oval type endless moving route (5) to simplify a device structure and lower equipment cost and running cost. The carriage positioned on the ground side is engaged with a carrier (37) driven along the curved portions (31a) and (32a), and the carriage is towed by the carrier (37) to run it over the entire length of the curved portions.

Abstract: A tire molding system having no possibility of prolonging the tact time for tire molding, not requiring a special installation space for endless circulation travel of a molding carriage, and having no danger of increasing noise and vibration or of early deterioration of carriage positioning accuracy. A tire molding system comprising work stations for assembling tire components on a molding drum, a molding carriage supporting the molding drum to move it to the respective work stations, and carriage guide means for guiding the movement of the molding carriage in a predetermined path, wherein the carriage guide means includes wheels disposed on two inner and outer endless rails and on the molding carriage and adapted to roll on the opposite side surfaces of the endless rails so as to regulate the carriage position in a direction orthogonal to the direction of extension of the endless rails, each endless rail being composed of a linear portion and an arcuate portion, the two portions being smoothly connected, the rail width (W) of the arcuate portion being narrower than the rail width of the linear portion.
