A tire building drum is described that includes an inboard section, a center section and an outboard section. The inboard section has a rotating spindle and a sliding shaft, and the sliding shaft is slidable within the spindle. The inboard section further includes a radially expandable bead lock device mounted on the spindle. The center section has an internal hub mounted on the sliding shaft and further comprises a plurality of tiles that are radially expandable. The outboard section of the drum is mounted on a distal end of the sliding shaft, and further includes a radially expandable bead lock device. The center section and the outboard section are each axially movable by sliding of the sliding shaft.

Tire building drum

A method supports a tire building assembly. The method comprises the steps of: supporting one end portion of a radially collapsible building drum for assembling a green tire; moving the end portion in a first direction by an actuator acting in the first direction; and moving the end portion in a second direction by the actuator acting in the first direction.

Method and apparatus for adjusting a tire building machine

A rotatable tire building drumhas a pair of axially and radially moveable bead locksand a radially expandable center building deck assemblywith two sets of deck plates when expanded forms a 360 degree solid deck surface. The deck plates have been sized to abut when fully expanded to form a solid 360 degree building surface to support a tire carcass. The two sets of deck plates are divided into a first set of even deck plates and a second set of odd deck plates, arranged in a sequence of at least 6 or more circumferentially adjacent abutting deck platesin an expanded state. In a retracted state, the first set of even deck platesmoves radially inward of the second set of odd deck plates, the first setunderlying the second set

Solid deck bead lock drum

A method for applying a sheet of flexible material to a cylindrical body is described. The sheet of material may be ply or a tire building component such as a liner. The method includes the steps of receiving the sheet of flexible material onto a conveyor belt of a conveyor table, wherein the conveyor belt can translate in the X direction, wherein the conveyor belt has a plurality of rollers rotatably mounted on the conveyor belt so they can rotate about an axis aligned with the X direction. The method further includes aligning a lateral edge of the sheet with an edge guide of the conveyor table by tilting the conveyor table and then tilting the conveyor table back to a level position. The method further includes moving a front edge of the conveyor table adjacent the cylindrical body; and applying the sheet onto the cylindrical body.

Method of applying ply to a tire building drum

The invention provides in a first aspect an applier apparatus for applying a sheet of flexible material to a cylindrical body such as a tire building drum. The apparatus includes a support frame; a conveyor table having one or more conveyor belts mounted thereon; said conveyor table further comprising a plurality of support legs, each support leg having an outer leg portion and an inner leg portion, wherein each inner leg portion is mounted to the support frame, said conveyor table being connected to each of the outer leg portion of the support legs; the outer leg portion of each support leg having a first end slidably received over the inner leg portion and a second end connected to a nut; and wherein the nut is mounted onto a linear screw which is rotatably mounted onto a second end of the inner leg portion; said linear screw being driven by a motor wherein the nut is raised and lowered by operation of the screw.
