  • Patent number: 8932043
    Abstract: Disclosed is a plastic trim reclaim process that recycles otherwise wasted trim into for reuse or densified composite bricks for resale. The device combines four sections to process trim scrap from a typical plastic extrusion process. The four sections comprise an input and feed section, a grinding and pre-sizing section, a compaction and sizing section, and a repelletizing and recovery section. The final product takes one of two forms: a compacted plastic brick or pellet-sized beads that can be directly reused in a new extrusion process. The compaction and sizing section utilizes a heating chamber and ram to force ground trim through an extruder, which is then cut into sections to form brick. The repelletizing and recovery section utilizes an extrusion process that feeds into a cutting plate, whereafter the sized pellets are cooled to solidify their structure prior to being vacuum transported into a container for reuse.

    Abstract: Flexible tubular film (10) is helically cut into a flat strip by unwinding the tubular film in flattened form by a tumbling unwinder (1), advancing the flat film tube to a tube expansion zone (17) in which the flat tube is expanded into a circular cylindrical tube and is passed axially over a hollow mandrel (14) slightly lower in external diameter than the diameter of the expanded tube to be cut by knife (18) helically while on the mandrel into a flat strip that is removed at an angle to the mandrel axis. The flat tube is longitudinally stretched by stretching rollers (107-112), which tumble with the tumbling unwinder. The apparatus further comprises stabilization means for stabilizing the orientation applied by the tumbling stretching rollers, applied to the helically cut film strip after it has been drawn from the mandrel.

  • Patent number: 8753104
    Abstract: Embodiments of the invention are used to provide ways of tire tread molding and retreading with a double tread rubber body having a unitary structure that comprises two treads in order to remove the need for buffing an oxide layer typically associated with tread molding and curing. Embodiments of the double tread molding and retreading methods also remove the need for cementing the cured tread to prevent future oxidation buildup. Once the double tread is cured and cooled, it is cut along the centerline with a double tread separation apparatus to expose a soft non-oxidized inner rubber. The cutting is much less energy intensive when compared to buffing with an expendable wire brush. There is no risk of spots of oxidized rubber being missed as is the case with buffing. There is little or no dust created.

  • Patent number: 8123515
    Abstract: This invention provides single-step pultrusion processes for producing fiber reinforced polymer (FRP) articles that may have variable cross sections and/or non-linear shapes. This unique capability results from the use of two sets of dies to form the article. The first is a set of moving dies connected together to form mating continuous loops of moving die links to: a) draw the FRP material into the apparatus; b) shape the cross section of the FRP material; c) cut the FRP material to the appropriate length; and d) hold the uncut FRP material in position for the next production cycle. The second set of dies forms a guide path mounted on opposing conveyers. The guide path includes heated die segments to define a curing section that may be non-linear. Cycling the moving die links through the curing section and/or cycling the conveyers provides a straightforward method for automated production of finished pultruded articles with unique shapes.

  • Patent number: 7758330
    Abstract: For forming a ready-to-bake, endless dough ring, a dough piece is first round kneaded in a round-kneading station and then fermented in a fermenting station. In a pressure station, flattening pressure is exerted on two sides of the dough piece for a flat round piece to produce. After a relaxation interval, an inside hole is punched into the relaxed dough piece in a punching station, with a dough ring being obtained. The individual stations of a corresponding dough treatment system are connected to each other by means of a conveyor. Then secondary fermenting of the shaped dough ring takes place, which is followed by baking of a ring article. The result is an efficient method of forming a ready-to-bake, endless dough ring. Producing the baked ring article can be completely automated.

    Abstract: A photo film cassette includes a spool core (13) on which photo film is wound in a form of a roll. A cassette shell (3, 4) contains the spool core in rotatable fashion. In each of a pair of disks (16, 17), a bearing hole (16a, 17a) is formed. The disks are secured to first and second ends of the spool core, and regulate edges of the photo film. To produce at least one kind of disk, a continuous sheet (27, 78, 88, 162, 171, 215) of thermoplastic synthetic resin is partially masked with a mask plate (48, 87, 160, 161, 170). A portion of the sheet emerging out of the mask plate is heated at temperature higher than a softening point of the sheet. The emerging portion is subjected to vacuum/air-pressure forming, so as to form a disk-like portion (20) in the sheet. The bearing hole and a contour of the disks is cut in the disk-like portion, to produce the disks.
