The invention relates to an assembly and a method for manufacturing a green tire and/or a green air spring. The device comprises a template having a shaping surface () for placing a tire component thereon comprising a layer of unvulcanized rubber for the green tire and/or green air spring. The shaping surface () is provided with an attachment surface () for at least temporarily retaining at least a leading section of the tire component. The attachment surface () comprises a number of adhering surface sections () with non-adhering surface sections () placed in between them, wherein the non-adhering surface sections () are at least partially receded with respect to the adhering surface sections (). In one embodiment the attachment surface () comprises a substantially saw-tooth-shaped cross-section.

Assembly and a method of manufacturing a green tire and/or an uncured spring

The invention provides a method and a device for manufacturing a breaker ply package for a green tire, wherein a rubber band is supplied by a supply device () that can be moved between a first position and a second position, wherein the supply device can be moved between a first position in which the supply device is set for supplying the continuous rubber band at a supply direction which with the conveyance direction includes a first angle that equals the first cord angle, and a second position in which the supply device is set for supplying the continuous rubber band at a supply direction which with the conveyance direction includes a second angle that equals the second cord angle, wherein the second angle is not equal to the first angle.

Method and device for manufacturing a green tire

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 (), wherein each set of arms is connected to an axially shiftable arm support (). 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 () () 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.

Tyre building drum with turn-up mechanism

Device () for manufacturing a rubber strip material comprising cord material. The device comprises an extruder () with an integrated gear pump () with adjustable pump speed and with a conveying screw for extruding unvulcanised rubber around the cord material for the purpose of producing a continuous rubber strip. The device furthermore comprises a control unit () for adjusting the pump speed of the gear pump, a measuring unit () for measuring the height and the width of the rubber strip and for emitting a measuring signal indicative of the measured height and width. The measuring unit can be connected to the control unit for adjusting the pump speed of the gear pump for emitting the measuring signal to it, wherein the pump speed of the gear pump can be controlled by the control unit at least based on the measuring signal.
