DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an assembly of devices for building a green tire, that is to say a non-vulcanized tire, hereafter in the description referred to as green tire, for vehicles, such as passenger cars.
Although many of such assemblies of devices are known, such as for instance from U.S. Pat. Nos. 5,213,651 and 5,399,225, there has up to now not been an assembly, or in other words combination, of known devices which is used for building a green tire, in which these devices are interrelated in a certain way, capable of providing an assembly which allows for a high production of green tires, a high flexibility in the type of tire produced, as well as a high quality of the green tire.
It is in fact an object of the present invention to provide an example of an assembly of devices for building a green tire which is capably of this.
According to the invention, an assembly of devices is provided for building a non-vulcanized or green tire for vehicles, the assembly being provided with a first machine house with two, coaxially disposed, belt building shafts extending in a first horizontal main direction, a first of the two belt building shafts carrying a belt building drum and a second of the two belt building shafts carrying a tread building drum, the tread building drum, seen in the direction of the first horizontal main direction, being disposed at a greater distance from the first machine house than the belt building drum, and with a belt building drive for separately driving the two belt building shafts, a second machine house with a shaft rotating about a second horizontal main direction, the second horizontal main direction being parallel to the first horizontal main direction and the second machine house, seen in the direction of the first horizontal main direction, being disposed at a greater distance from the first machine house than the tread building drum, the rotating shaft of the second machine house carrying two carcass shafts disposed at a distance from and parallel to each other, each carcass shaft being parallel to the first main direction, a first of the two carcass shafts carrying a first carcass drum and a second of the carcass shafts carrying a second carcass drum, and with a main shaft drive for causing the rotating shaft to rotate and two carcass shaft drives for separately driving the two carcass shafts, the first and the second carcass shaft, respectively, being rotatable by the rotating shaft up to being in line with the first main direction, a transfer track with a direction of transfer parallel to the first horizontal main direction wherein the transfer track, seen in vertical direction, is disposed below the belt building drum and the tread building drum and extends, seen in vertical direction, up to below a carcass drum rotated in line with the first main direction, a first transfer ring disposed on the transfer track and movable between the belt building drum and the tread building drum, a second transfer ring disposed on the transfer track and movable between the tread building drum and a carcass drum rotated in line with the first main direction, a breaker ply servicer for supplying breaker plies to the belt building drum, a car ply unit disposed below the breaker ply servicer, seen in vertical direction, for supplying rubber-surrounded nylon cords to the belt building drum, a tread servicer for supplying treads to the tread building drum, a winding unit, disposed on the first transfer ring, for supplying a nylon cap ply to the belt or tread building drum, a bead holding and bead placing unit, movably disposed on the transfer track for supplying beads to a carcass drum rotated in line with the first main direction, a carcass component servicer for supplying carcass components to the other carcass drum when one of the carcass drums is rotated in line with the first main direction, a tread stitcher disposed below the carcass component servicer with at least one stitching roll for stitching an assembly of inter alia breaker ply and tread against the carcass components pr
