Abstract: Pressure roll for a tire building apparatus for preparing pneumatic tire blanks with a building drum for receiving tire layers. The pressure roll cooperates with the building drum has a plurality of discs mutually slidable with respect to one another and on a shaft so as to extend radially with respect to the building drum, the discs being mutually uniformly shaped, and each disc having an interior part and an exterior ring surrounding the interior part and being rotatable about a ball bearing, the interior part having a recess whose sidewalls slide radially on the sidewalls of the shaft and whose length is greater than the corresponding size of the shaft. The shaft extends in the longitudinal direction of the pressure roll. The shaft is provided with a number of radially directed bores equal to the plurality of discs, and in each bore a piston is disposed that engages the interior part of the respective disc concerned.

Abstract: Assembly for building a green or non-vulcanized tire for vehicles, such as passenger cars, the assembly being provided with two, separately drivable, building drums (13, 16), in line with each other, for the belt and the tread; two carcass drums (40, 40') located parallel to each other, mounted on a common, rotatable shaft (39), the rotatable shaft being rotatable such that the one Carcass drum (40) and the other carcass drum (40'), respectively, can be in line with the building drums; a first (14) and a second (19) transfer ring, both movably disposed on a transfer track (18), the first transfer ring (14) being movable between the belt building drums (13, 16) and the second transfer ring (19) being movable between the carcass drums (40, 40') and the closest building drum; a breaker ply servicer (30) and a cap ply unit (31) for supplying tire components to a first building drum (13); a tread servicer (32) and a winding unit (15) for supplying tire components to a building drum; a bead holding (27) and bead pl

Abstract: A transfer unit for supporting and moving a tread/belt assembly is provided with a stable cylindrical base with a longitudinal axis and with a passage part provided with arms which are laterally arranged on the base body and which extend essentially in a longitudinal direction. Gates for radially admitting rollers of the pressure roller unit are formed by the base body and the arms and have a pass through opening which is located between the free ends of two adjacent arms.
