The workpiece is held by a gripping surface over most of the innermost turn of a spirally wound spring and coil. The workpiece is grasped circumferentially over its outer surface without excess contact pressure at any particular point. A tendency of the machining operation to rotate the workpiece serves to secure the workpiece more tightly in position by tightening the outer turns of the spring band coil. A rotatable tensioning member acts under the influence of a biasing spring to decrease the diameter of the innermost turn of the spring band coil to bring the gripping surface into contact with the workpiece. A method for adapting the work-holding apparatus to smaller or irregularly shaped workpieces consists of molding an annular piece around the workpiece.

  • Patent number: 4770289
    Abstract: A wrapping machine wherein article units are wrapped by a shrinkable web to form a package. The machine includes a conveyor which includes an upper article supporting run. The conveyor has regularly spaced openings and associated with the rear of each opening is a web pulling bar. Article units are fed to the conveyor run in timed relation to conveyor movement and a series of retarder bars, moving at a slower rate, pull the web in front of each article unit to be wrapped with the article unit then bearing against the retarder bar and being slowed to the speed of the retarder bar with the conveyor moving therebeneath. A clamp bar moves down behind each article unit, draws the web down behind the article unit and then clamps the web to the article unit. In advance of this, and before the clamp bar engages the article unit, web drawing means engages the web between two adjacent article units and draws the same down into the associated conveyor opening and engages the web with the article pulling means.

  • Patent number: 4706973
    Abstract: Top jaw assemblies combined with a chuck. Each of these top jaw assemblies comprises a body having a base projecting radially inwardly when mounted to the chuck, a cylindrical wall in the body which with the base provides a cutout portion and in which a workable rotatable workpiece gripping member or "slug" is mounted and secured to the base. The slug's periphery or annular wall conforms to and engages the cylindrical wall and includes an opening having a counterbored hole in which a screw mounts and extends below the slug to thread to a threaded aperture in the base. The slugs are machinable to provide different gripping surfaces contoured to the configuration of different workpieces, and are rotatable to provide the necessary reset position for such gripping surfaces in relation to the different sized workpieces. The base can be slightly inclined so as to force the slug's diameter against the matching radius of the cylindrical wall when the slug is torqued to the base.

  • Patent number: 4484381
    Abstract: An assembly comprising a board 1 and a mechanism 17 for clamping a marginal portion of the board adjacent an edge between two opposed substantially flat parallel walls 7a. The mechanism 17 is mounted on a major surface 19 of the board 1 and includes a spring strip 21 extending longitudinally along the mechanism, and having corrugations transverse to its length. An elongate cam 27 extends along the length of the strip 21, overlying the strip, and being supported for rotation about its longitudinal axis. Rotation of the cam 27 causes expansion of the mechanism 17 in a direction normal to the surface 19, limitation of the expansion by the walls 7a leading to compression of the corrugations in the strip 21.
