Disclosed is a festooner and a method for buffering a strip, wherein the festooner includes a first holder and a second holder which are oppositely movable towards and away from each other in a buffer direction to vary a buffer capacity of the festooner, and a first set of buffer rollers and a second set of buffer rollers held by the first holder and the second holder, respectively, wherein the first set of buffer rollers and the second set of buffer rollers define a meandering buffer path between them. The festooner further includes an endless drive element for driving each buffer roller, wherein the festooner further includes an overlength collector for collecting and paying out an overlength of the endless drive element.

Disclosed is a strip applicator, a strip-winding station and method for applying a strip to a strip-winding drum, wherein the strip applicator includes an applicator member applying the strip to the strip-winding drum at an application position and a supply section receiving the strip in an input direction at a supply position and supplying the strip to the applicator member in an output direction. The applicator member is movable in an offset direction transverse to the output direction to offset the application position relative to the supply position. The supply section has an input member at the supply position for receiving the strip in the input direction and an output member for outputting the strip to the applicator member in the output direction. The output member is movable relative to the input member from a start position towards an offset position in the offset direction.

A tire building method, in particular for strip-winding, includes the step of: Also disclosed is a tyre building system and a measurement tool.

Tire building method and tire building system, in particular for strip-winding

Disclosed is a cutting device and a method for cutting a continuous strip into tire components. The cutting device includes a knife for cutting the continuous strip along a cutting line in a working plane and a feeding assembly with a feeding member for feeding the continuous strip in the working plane to the knife in a feeding direction that intersects with the cutting line at a cutting angle. The feeding member, and the knife are rotatable with respect to each other about a rotation axis perpendicular to the working plane for adjusting the cutting angle. The feeding assembly further includes an input member for receiving the continuous strip in an input direction into the cutting device and one or more guide members for guiding the continuous strip from the input member to the feeding member, wherein the input member is placed in line with or substantially in line with the rotation axis.

Device and method for cutting a continuous strip into tire components

The invention relates to a method and centering assembly () for centering a tire component (), wherein the method comprises the steps of placing the tire component on and conveying it from a first conveyor () towards a second conveyor (), determining the position of a first longitudinal edge (), transversely moving the first conveyor () and thereby aligning the first longitudinal edge () along a first reference on the second conveyor (), conveying the tire component from the first conveyor () onto the second conveyor () while determining the position of a second longitudinal edge (), wherein the tire component has a center between the first longitudinal edge () and the second longitudinal edge (), conveying the tire component from the second conveyor () towards a drum (), laterally moving the drum () to align the center of the tire component with a center of a desired application position of the tire component on the drum, and conveying the tire component from the second conveyor () onto the drum ().

Method for transferring and placing beads for tires, providing:

Method for transferring and placing beads for tyres, device for carrying out such a method and spacer to be used in such a method and/or device

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

Tire building drum having a drum shaft and two drum halves arranged around the drum shaft. In the drum shaft one threaded spindle is arranged. On either side of the center of the tire building drum a driving nut is arranged on the spindle. Each driving nut is fixedly connected to the drum half in question via a connection part. Each drum half has a folding arm unit that is connected to the drum half in question so as to swing. The folding arm unit is movable in axial direction of the tire building drum. Each drum half further has a bead ring core clamping unit intended for supporting and clamping a bead ring core. The bead ring core clamping unit is arranged on a cylindrical part. The cylindrical part is provided with a cylinder slot for accommodating the connection part and with a locking mechanism. The locking mechanism can be brought into engagement with the drum shaft. At engagement of the locking mechanism in the drum shaft the folding arm unit can be moved with respect to the cylindrical part in axial direction of the tire building drum.

Method for manufacturing a green tire using a building drum and a transfer device. In the method tire components are arranged on a building drum. In one step of the method the transfer device is placed around the building drum. The method further comprises a step during which a last manufacturing process for a green tire is carried out on the building drum, and a removal step during which a removal device removes the green tire from the building drum, wherein the removal device is provided with projecting elements that can be placed up to a distance from and around the outer circumference of the green tire and which projecting elements can be placed such so as to engage the outer side of the green tire. The removal step further comprises during the step in which the transfer device is placed around the building drum, placing the projecting elements up to a distance from and around the outer circumference of the building drum.

Method for manufacturing a green tyre using a building drum and a transfer device

Device for manufacturing a cut-to-length pre-assembly for a tire, wherein in the pre-assembly first and second side walls are situated on either side of an inner liner. The device comprises a supply conveyor for conveying the cut pre-assembly to the building drum. The device is provided with a first side wall measuring device for measuring the length of the first side wall of the cut pre-assembly and for giving a first side wall measuring signal indicative of the measured length of the first side wall, with a second side wall measuring device for measuring the length of the second side wall of the cut pre-assembly and for giving a second side wall measuring signal indicative of the measured length of the second side wall, and with an inner liner measuring device for measuring the length of the inner liner of the cut pre-assembly and for giving an inner liner measuring signal indicative of the measured length of the inner liner.
