摘要： A transfer ring of the type having a plurality of shoes arranged in a substantially circular configuration to define an inwardly-facing segmented cylindrical gripping surface, and a shoe for use in such a transfer ring, are disclosed. Each shoe comprises an arcuate interior surface defining a segment of the cylindrical gripping surface. The interior surface of each shoe has a first arcuate edge and an opposite second arcuate edge arranged substantially parallel to one another, and opposite first and second end edges extending between respective ends of said first and second arcuate edges. Each first end edge of each arcuate surface is mounted adjacent the second end edge of an adjacent arcuate surface, and the first end edge of at least one of the arcuate surfaces defines a varied or irregular shape along its arcuate surface.

摘要： A tire building drum is disclosed having first and second sets of deck segments, disposed in an alternating configuration about a central shaft. Each of the segments is mounted to a pair of axially movable hub units via an associated scissor linkage. The scissor linkages of the first segments are slidably mounted to the hub units and biased toward a median plane of the tire building drum. When the hub units are separated, the second segments are disposed radially inwardly of and between the first segments. Movement of the hub units toward one another through a first range of motion expands the first deck segments to an expanded diameter of the drum, and movement of the hub units toward one another through a second range of motion expands the second deck segments to allow the second deck segments to be received between the first deck segments.

摘要： An improved belt and tread drum incorporating an improved segment is disclosed. Segments are mounted in side-by-side relationship about a central axis for radial movement inwardly and outwardly with respect to the central axis and include arcuate outer surfaces that collectively define an outer circumferential working surface of the drum. The segments each define an arcuate outer surface defining a circumferential dimension, the outer surface having varied curvature along the circumferential dimension.

摘要： A multi-piece sealing sleeve is disclosed. The multi-piece sealing sleeve includes annular first and second layers of a substantially air-impermeable material. The first layer has an inner edge sized to surround a base portion of the tire shaping drum. An outer edge of the first layer extends radially outwardly to overlie at least a portion of a radially expandable and collapsible structure defined by the tire shaping drum. The second layer is sized to overlie and establish sealing engagement with at least a portion of the first layer and a bead seat defined by the radially expandable and collapsible structure of the tire shaping drum. The first and second layers cooperate to establish a substantially airtight seal between the tire shaping drum base portion and the bead seat.

摘要： A tire building drum is disclosed. A thrust plate is mounted at a tapered end of a central shaft. An actuator is slidable along the shaft between first and second positions. Arcuate segments are arranged in a circumferential relationship about the shaft to define a working surface. First guide rails are slidably secured to the thrust plate, with a first end of each first rail mounted near a first end of one of the segments and a second end extending radially inwardly along the thrust plate. Second guide rails are slidably secured to the actuator, with a first end of each second rail mounted near a second end of one of the segments and a second end extending radially and axially inwardly along the actuator. Each of the guide rail second ends extends radially inward toward the inwardly tapered shaft portion when the actuator is in the first position.
