  • Patent number: 4756140
    Abstract: A process of packaging goods, especially foodstuffs, comprising enclosing the goods in a sheet of thermoplastics material, preferably a bag, so as to form a package which presents two unsealed juxtaposed surfaces. The package is then placed in a container, one wall of which is made of deformable sheet material, preferably a sheet made of a silicone resin, which is stable at the sealing temperature of the thermoplastics material. The container is then connected to a source of vacuum and when the pressure has been reduced in both the container and the bag sufficient heat is applied to the deformable sheet in the vicinity of the juxtaposed surfaces to cause them to become sealed together. In a further embodiment of the invention vacuumization of the container including the bag is followed by the injection of a preserving gas such as carbon dioxide.

  • Patent number: 4753102
    Abstract: An arrangement for coupling and decoupling gripper rail partial sections of a transfer press in which the gripper rail partial sections are to be clamped together flange-like. The clamping bolt is adapted to be actuated by an adjusting drive in the displacement direction and in a rotary movement. A slide member displaceable in the end portion of the gripper rail partial section includes slide guidances which extend at an inclination to the displacement direction and in which pressure members are displaceably supported. During the displacement of the clamping bolt, the slide member is moved along and the pressure members are displaced into the separating gap between the gripper rail partial sections under abutment at stop members in the end portion of the gripper rail partial section to be coupled. The clamping anchor is adapted to be fixed at a ball socket by rotation and by retraction.

  • Patent number: 4748708
    Abstract: A spike harrow tooth is fabricated by cold forming a metal blank which is provided from appropriate bar stock, the blank having a length for a single harrow tooth. The blank is placed in a first press, oriented with opposite edges of the square configuration aligned in the direction of press closing and opening. The first press is equipped with dies for displacing the metal at one end of the blank, by flattening the opposite edges to thereby displace the metal crosswise and form an enlarged head. Simultaneously, metal is displaced by dies in the first press from opposite side edges of the blank at the other end of the blank for partially forming a point with outwardly bulging excess portions. The partially formed blank then is placed in a second press equipped with dies for removing the outwardly bulging excess portions into waste chips.

  • Patent number: 4747253
    Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. During the forming, which is done by means of external forming devices, the contents are made use of as an internal mandrel or a holder-up for the forming devices, so that the desired shape can be achieved without creasing or other deformations. The above-mentioned forming principle works less well if the packing containers are not to be completely filled but have a certain air space or headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved.

  • Patent number: 4744237
    Abstract: A box-like frame member is formed by compressing an internally-pressurized tubular blank within a die having a cavity conforming to the final box-like cross section desired for the product, and increasing the pressure to exceed the yield limit of the wall of the blank to expand the blank into conformity with the die cavity. The blank is selected so that the final product and the die cavity have a circumference preferably no more than about 5% larger than the circumference of the blank, to avoid weakening or cracking of the blank through excessive circumferential expansion. The internal pressure forces the blank evenly into the corners of the die on closing and allows the blank to be confined within the die without sections of the die pinching the blank on closing of the die.

  • Patent number: 4741196
    Abstract: Successively formed cans or cups are quickly and smoothly removed from beneath the lower die shoe of a high speed forming press by an elongated dual lane stainless steel air conveyor having closely spaced upper and lower parallel walls defining an air chamber therebetween. A blower supplies air to the discharge end portion of the conveyor, and the inner end portion of the conveyor top wall defines two cup receiving zones adjacent corresponding outlets formed by upwardly projecting air deflecting hoods. Each hood directs a high flow of air horizontally across the adjacent receiving zone and longitudinally along the top conveyor wall to move each cup quickly from the receiving zone. Longitudinal extending parallel ribs project upwardly from the top wall for each lane, and a set of louvered slots are formed within the top wall between the ribs to maintain the linear and uniform flow of the cups to the discharge end of the conveyor.

  • Patent number: 4739644
    Abstract: A cup-shaped raw workpiece having a bottom panel and a cylindrically-shaped circumferential panel is positioned facing downwardly on a movable lower punch having a forming gear profile. The lower punch is provided in a die having an orifice portion which together with the gear profile defines an orifice. A resilient mechanism resists downward movement of the lower punch. An upper punch is lowered to hold the bottom panel of the workpiece against the lower punch and pushes the workpiece to extrusion form the inner surface thereof through the orifice. An escape groove for excess metal can be provided in the bottom inside corner of the workpiece at the juncture of the circumferential panel and the bottom panel. The lower punch can be provided with an upwardly extending protrusion near the outer circumferential edge of the upper end surface thereof which has an outer chamfered circumferential edge.

  • Patent number: 4735071
    Abstract: An apparatus for continuously producing a tube having helical grooves in its inner surface comprising a tube twising rotary frame, a pay-off drum mounted on the rotary frame for paying off a tube having straight grooves in its inner surface, a nozzle provided at the front end of the rotary frame and having an adjustable inside diameter for sending out the paid-off tube forwardly of the rotary frame, and at least one pair of catching rollers provided in front of the rotary frame and disposed close to the nozzle for holding the sent-out tube. Each of the catching rollers is formed in its peripheral surface with a groove of semicircular cross section in conformity with approximately one-half of the outer periphery of the tube. With the rotation of the rotary frame, the straight-grooved tube is twisted between the nozzle and the catching rollers, whereby the straight grooves are deformed to helical grooves.
