| 20090133809 | METHOD AND TYRE BUILDING DRUM FOR BUILDING A TYRE - When building an unvulcanised tyre from tyre components using a tyre building drum, the mutual distances considered in axial direction between a bead ring segment, a first end and a steering element of a folding arm in question are chosen such that at movement of a steering element towards the bead ring segment a steering surface comes to abut the steering element so that the roller element can be moved from a first position, after which the roller element presses an outer part of the tyre components against a bead ring core to be placed on the bead ring segment while simultaneously the roller element moves away from the longitudinal axis, wherein the steering element moves along the steering surface until the stop of the annular steering segment abuts an annular folding arm segment, after which the folding arm swivels about a swivel axle and the steering element comes to lie apart from the steering surface. | 05-28-2009 |
| 20090133842 | TYRE BUILDING DRUM FOR BUILDING AN UNVULCANISED TYRE - Tyre building drum for building an unvulcanised tyre using tyre components of rubber. The tyre building drum comprises two folding arm units arranged at least substantially symmetrically with respect to the middle of the tyre building drum, which folding arm units are each connected to a folding arm bearing body so as to swivel. Both folding arm bearing bodies can be moved in axial direction of the tyre building drum. Via a first spindle both folding arm bearing bodies can be moved synchronously with respect to each other in axial direction. The tyre building drum further comprises two bead ring core units arranged at least substantially symmetrically with respect to the middle of the tyre building drum, each of the bead ring core units being intended for supporting a bead ring core. Each bead ring core unit comprises a bead ring core bearing body, wherein via a second spindle both bead ring core bearing bodies can be moved synchronously with respect to each other in axial direction. The first spindle and the second spindle are spaced apart from each other in radial direction. | 05-28-2009 |
