With Means To Feed Work Patents (Class 82/102)
  • Patent number: 7398716
    Abstract: When a tube is to be cut into a plurality of sections, a tube feed assembly is operated to rotate the tube and to move the tube along its longitudinal central axis into a work station. The tube and a mandrel move into a telescopic relationship at the work station. The tube feed assembly presses an end of the tube against a stop surface on a stripper at the work station. A plurality of knives are moved into engagement with the tube to cut the tube. Relative movement between the stripper and mandrel separates the sections of the tube from the mandrel. A scrap end section of the tube is directed to a scrap receiving location. Other sections of the tube are directed to a product receiving location.

  • Patent number: 5361469
    Abstract: In an apparatus for cutting a tubular film into an elongated strip wherein the tubular film is fed at a given velocity in flattened form from a supply reel to an expansion zone where the film is expanded into a tube, advanced after such expansion along a mandrel, cut into a flat strip while advancing along the mandrel, and the flat strip is removed from the mandrel at an angle to the mandrel axis, the mandrel is hollow and air is introduced into the hollow mandrel under sufficient pressure that the flattened film is expanded into a relatively stiff cylindrical tube that makes a sliding fit with the mandrel and resists deformation while being supported thereon, Improved positive control over the film during its expansion and advance to the mandrel is achieved by means of moving surfaces, e.g. endless belts or roller arrays, that define a diverging expansion zone and are driven at a velocity equal to the velocity at which the film is fed.

  • Patent number: 5257560
    Abstract: A trimmer apparatus (10) comprising dual moveable belts (64) and (90) for removing a dome scrap (12) from a hollow, blow molded plastic bottle (14), is described. The dual belts are supported on spaced apart pulley systems (20) and (22) forming a linear path (24) along which the bottle travels. The distance between the pulley system is adjustable for different size bottles. A groove (12A) on the dome scrap is engaged by the belts which are rotating in a similar direction. However, one belt is moving somewhat faster than the other. This provides for moving the bottle linearly along the path, while spinning the bottle. As the bottle spins past a knife blade (112) the dome scrap cut from the bottle.

    Abstract: Flexible tubular film is helically cut into a flat strip by feeding the tubular film in flattened form from a supply source to a film feeding means advancing the flat film tube at a predetermined velocity to a tube expansion zone in which the flat tube is expanded into a generally cylindrical tube and passed axially over a hollow mandrel slightly less in external diameter than the diameter of the expanded tube to be cut helically while on the mandrel into a flat strop that is removed at an angle to the mandrel axis. The tube is expanded in the zone by inflation with air fed through the mandrel in a direction countercurrent to the direction of tube movement and under a pressure sufficient to render the expanded tube stiff as it slides over the mandrel and resistant to deformation while being helically cut.

  • Patent number: 4026171
    Abstract: Work pieces, particularly thin-walled shells of can dimension, are transferred from a magazine at a supply station to another station by a reciprocal shuttle having a pocket for receiving the shells in ready position at the supply station; at the other station, a reciprocal loader transfers the shell laterally from the shuttle to a work station where the work product is produced. The shuttle incorporates a second pocket to receive the work product and includes a surface for gating the supply magazine as an incident to shuttle travel. By locating the path of the shuttle above the path of the loader, it is possible to coordinate shuttle and loader movement for maximum utilization of time. Shells fed to the magazine are constantly aligned inside the magazine to assure effective bottom feed from the magazine to the shuttle.

  • Patent number: 3985221
    Abstract: A tube feeder has a longitudinal support equipped with two rows of wheels which support various diameter tubes and a loader for delivering tubes one at a time to the wheels. The loader comprises transverse tracks mounted on the longitudinal support and cooperating lifter blades associated with an inclined storage rack. The height of the longitudinal support is adjustable to locate the centerlines of various diameter tubes on the same fixed centerline. As the height of the longitudinal support is adjusted for a particular diameter tube, the loader is automatically adjusted to handle tubes of the same diameter.
