Abstract: Methods of machining a single piece hub with integral upper and lower female cones includes providing a single piece hub with upper and lower conical voids having respective narrow ends proximal each other and respective wide ends distal each other. Surfaces of the voids are machined using a tool provided from a single side of the hub that is dimensioned to fit through an opening defined by the interface between the narrow ends of the conical void. The tool can be moved parallel to a rotational axis for accessing conical surfaces of both voids and perpendicular to the rotational axis while contacting the surfaces so as to produce a final machined surface.

Abstract: To simplify fabrication of an integral hub piece, the opening between the upper and lower female cones in this hub has sufficient width or radial dimension to allow access to both cones from one side of the hub with the cutting tool. A cutting tool is used which has a width smaller than the opening between the cones. Preferably, the tool has a width which is about equal to or smaller than an angular dimension through this opening which is defined by extending surfaces of the upper and lower female cones. If this limitation is satisfied, both cones can be created with a single machine set up operating from one side of the integrated hub. Preferably the tool should only move orthogonal or parallel to the cutting tools rotational center axis.

Abstract: A shuttle driving assembly (10) including an open shuttle (22) rotatably driven on an automatically opened support frame (16) by a plurality of drive roller assemblies (85,87) carried by the frame (16). Each drive roller assembly (85,87) has a drive roller pulley (84) and at least one with plural belts (192,191,190,188,186) driving groups of the drive roller assemblies. The drive rollers contact a groove (115) on the shuttle (22) to provide a positive and responsive power transmission therebetween. The shaft (82) of each drive roller assembly (85,87) is mounted in a non-concentric bearing in a web (30) of the support frame (16) to provide adjustment of the position of the drive rollers (92) relative to the shuttle (22) for centering the shuttle (22) relative to the frame (16).

Abstract: An apparatus (30) and method is provided for holding and tacking an elongate material (12) onto a body (14), which body (14) may be toroidal in shape. The material (12) is applied to the body (14) by means of a shuttle (22) rotating about the body (14) in a plane transverse to a plane containing the body (14). The apparatus (30) includes a tacker arm (76) having a clamping means (104) for clamping and unclamping the end of the material (12), extending from the shuttle (22), to the arm (76). The arm (76) is pivotally mounted on a carriage (58) for movement between a first position, wherein the material (12) clamped to the arm (76) is held against the body (14), and a second position, spaced from the body (14). In the first position of the arm (76), the body (14) will move the arm (76) until the clamping means ( 104) unclamps the material (12) whereupon the arm (76) is pivoted to the second position.

Abstract: An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material. The carton preferably includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carbon may be consumed by a user. The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carbon blank upon a rotating heat sealing and alignment drum.
