Abstract: Disclosed is a tire building drum and a method for shaping tire components on the tire building drum, wherein the tire building drum has cover plates extending in the circumferential direction between each pair of directly adjacent turn-up arms to close gaps between the turn-up arms in the circumferential direction. The cover plates are arranged to remain at the first radius when the turn-up arms are moved from the level orientation towards the turned-up orientation.

Abstract: Provided is a tire building drum and a method for shaping tire components on the tire building drum, wherein the tire building drum has an annular sleeve that extends over turn-up arms in the longitudinal direction of the turn-up arms. The sleeve is elastic in the circumferential direction and fits elastically around the turn-up arms. The sleeve is provided with inelastic reinforcement elements extending in at least a part of the sleeve in a reinforcement direction transverse to the circumferential direction of the tire building drum, and has a fixed end that is retained in the axial direction and a movable end that is movable over the turn-up arms in their respective longitudinal directions.

Abstract: Tire building drum having a turn-up mechanism for use in building an unvulcanized tire using rubber tire components, having two sets of turn-up arms (14), wherein each set of arms is connected to an axially shiftable arm support (17). The tire building drum is provided with means on the one hand for shifting the arm supports in a first direction to move the sets of turn-up arms axially towards each other, wherein the arras are tiltable in radial planes from a starting position to a tilting position, and on the other hand for in a second direction, opposite the first direction, shifting the arm supports to move the arms axially apart from the tilting position into the starting position. The tire building drum is provided with a pneumatic detection device (20) (23) for detecting whether at least one of the moving parts, such as the arms or the clamping device, are in the starting position, and for giving a detection signal indicating whether or not the arms are in the starting position.
