A transfer ring for supporting a belt and tread package about a tire carcass for inflation of the carcass within the package during a tire-making process includes a plurality of shoes which are movable inwardly and outwardly for purposes of grasping or releasing a package positioned between the shoes. Components are provided for moving the shoes inwardly to a radial position about a package; and at this radial position, the shoes apply to the package a biasing force for maintaining a substantial uniform pressure about the package if it were to contract in size after the shoes are moved to the radial position. A braking arrangement is provided which prevents the shoes from moving outwardly of the radial position when a tire carcass is thereafter inflated within the package to thereby limit the diameter of the package during the carcass-inflating process.

A belt and tread drum having an annular shell comprising a plurality of circumferentially spaced segments, each of which is mounted on a carrier which disposed in circumscribing relationship to a generally cylindrical actuator rotatably connected with a reciprocating piston disposed within a cavity defined between the actuator and a hub fixed to a central core of the drum. Translational movement of the piston between extended and retracted positions in a direction parallel to the rotational axis of the drum is converted into selected rotational movement of the actuator relative to the hub. A plurality of sets of links interposed between the segments and the actuator and hub have their first ends commonly pivotally pinned to a segment. The second end of one link of each set of links is pivotally pinned to the actuator and the second end of the other link of each set of links is pivotally pinned to the hub. Rotation of the actuator relative to the hub controls the arcuate separation of these second ends such that bringing these second ends toward contiguity moves the segments radially outwardly, and conversely, moving these second ends arcuately apart serves to move the segments radially inwardly of the drum.

A rotatable drum (10) for use in the manufacture of vehicle tires, the drum including a plurality of segments which collectively define an outer circumference (32) of the drum. The segments are divided into first and second end portions (15,17) which are individually mounted for axial and radial movement between expanded and retracted positions relative to the rotational axis (16) of the drum. Each end portion of segments is further divided into first and second groupings (23,25), the segments (18,18') of the first and second groupings (23,25) being disposed in alternating juxtaposition with respect to the segments of the second grouping (18') and with the segments of the first grouping being movable axially further and radially faster than the segments of the second grouping as the segments are moved between their expanded and retracted positions so that the segments of the second grouping are received in overlying relationship to the segments of the first grouping as the segments of the first and second groupings are simultaneously moved radially inward toward the rotational axis of the drum. A third grouping 23 of the segments of each end portion of segments is provided for, with these segments (19,19') being received in overlying relationship to the segments of the first and second groupings. Further, in a preferred embodiment, each segment is provided with a shell member (24,26), with the shell members collectively defining the outer cylindrical surface (32) of the drum.

Tire-making apparatus () defining an outer or inner circumference () to serve as a forming surface or as a circumference-engaging surface, respectively, utilizes a frame () having a central axis () and a plurality of multi-sectional segments () which are moveable radially with respect to the central axis and include arcuate surfaces which collectively define the apparatus circumference. Each segment includes a primary section () and a secondary section () which flanks the primary section. The primary and secondary sections are connected so that as the segments are moved radially of the central axis, the primary and secondary sections move relative to one another along the circumference of the apparatus to help maintain the uniformity, or roundness, of the surface of the circumference collectively defined by the segments.

Apparatus including a frame, preferably circular in geometry and having a cental axis. At spaced apart locations about the circumference of the frame there are provided a plurality of links, each of which is pivotally mounted on a the frame and each of which carries a shoe having an arcuate surface. Each link includes at least one leg portion having an outboard end, The outboard ends of the leg portions of the plurality of links are interconnected with one another and with a drive mechansim whose operation serves to rotate the interconnected links in unison about their respective rotational mountings to the frame. As the links are rotated, their respective shoes are caused to move along an arcuate path which repositions the shoes generally radially inwardly or outwardly with respect to the central axis of the apparatus. To retain the circularity of the arcuate surfaces of the shoes as they are moved radially inwardly and outwardly, the shoes are interconnected by respective rigid rods. One end of each rod is fixedly anchored in a slot opening outwardly of one side margin of a first shoe and projects therefrom to have its opposite end slidably received in a second slot in a circumferentially adjacent shoe.

A flange for a tire building drum having a transverse central plane and including a central shaft having a longitudinal axis which defines a rotational axis of the drum including first and second sets of outer-circumference defining shoes which are expandable from radially retracted positions internally of the drum to radially extended positions to define first and second mirror image circumferential radial flanges which are disposed on respective ones of the opposite sides of, and parallel to, the transverse central plane of the drum, each set of shoes including a plurality of individual shoes, each of which is a generally triangular geometry when viewed in a plan view thereof and having respective apices, bases and opposite sides.

A belt and tread drum for use in the manufacture of vehicle tires and having a plurality of circumference-defining segments whose radial position is determined by a camming means. The extent of movement of the camming means is selectable by stop means associated with a central shaft which serves to mount the camming means and the stop means. Visual indication of the selected circumference of the drum is provided.

A tire building machine is disclosed that includes an adapter for use between a tire building drum and a drive mechanism that would otherwise be incompatible. In one form of the invention a tire building drum has collapsible outer drum segments that are movable between extended and retracted positions, and a rotatable shaft is connected to extend and retract the segments in response to rotation of the shaft. A drive mechanism rotates the drum and also includes an actuation mechanism that moves reciprocally between first and second displaced positions. The adapter rotates the rotatable shaft in response to reciprocal movement of the actuation mechanism and, thereby, extends and retracts the segments. In this construction, a drive mechanism that provides a reciprocating actuation movement can be combined through the adapter to drive a drum which requires a rotating actuation movement.

A bearing assembly for rotatably supporting a conveyor roller tube for a belt conveyor or the like about a fixed shaft which includes a housing to which a roller tube is attached, an end cover positioned on the fixed shaft adjacent one side of the housing, and a bearing interposed between the housing and end cover permitting rotation of the housing relative to the end cover. The end cover completely covers the end of the shaft about which it is positioned and cooperates with the housing for effectively protecting the bearing from exposure to contaminants. During conveyor operation, the end cover prevents migration of contaminants along the shaft from the end thereof and the housing centrifugally expels contaminants which may enter the space between the housing and the end cover. In addition, the housing, bearing end cover, and shaft cooperate to limit axial shifting of the assembly components relative to one another.
