Publication number: 20020117033Abstract: In a method and apparatus for rotating loose laminations in a loose lamination die, a strip is fed through the die to a rotatable blanking chamber of a blanking station. There, a punch engages with a die ring to punch a lamination free from the strip. The rotatable blanking chamber is biased in an upwardly direction. When the punch is not engaging with the die ring, the rotatable chamber is in an upward position wherein a gap develops between laminations retained at a bottom of the rotatable chamber, and those laminations lying directly below the rotatable chamber. The rotatable chamber can then be rotated without damage to the laminations at the gap because of the presence of the gap. Thereafter, a succeeding lamination can be punched after the rotation has occurred. As the punch engages the strip on top of the die ring, the rotatable chamber is pushed downwardly so that the gap at the bottom of the rotatable chamber disappears.Type: ApplicationFiled: May 1, 2002Publication date: August 29, 2002Inventor: Mark Bender

Patent number: 4741233Abstract: A system for spreading and severing material utilizing a roller movable over a lower substrate and carrying with it a loop of material for spreading without tension. One or two plies are spread as a function of roller travel prior to severing from a source. If two plies are spread, severing of the loop occurs at the roller by an element movable with the roller. A second severing element is located at one end of the substrate to separate material from the source. A top platen carries a removable substrate having thereon multiple patterns. The patterns are defined by a resistance wire having thermal expansion joints and carried by stand-off insulators mounted on the removable substrate. When the wires are brought into contact with the material on the lower substrate, severing occurs. Multiple cycles of spreading and severing may occur prior to removal of the lower substrate.Type: GrantFiled: October 20, 1986Date of Patent: May 3, 1988Inventor: Verl M. Mershon

Patent number: 4716800Abstract: For reducing the refitting time of high-speed presses as a consequence of the adaptation of the distances of stacking spindle and support members to the dimensions of the cutting tool to be interchanged and of the blank, the stacking spindle and the support members are arranged on interchanging rails adapted to be displaced out of the press table. Upon reaching the required height of the stack, the spindle tip adapted to be separated from the stacking spindle is held by a retaining device consisting of adjusting means and slide member so that the stack can be lowered to the discharge conveyor plane.Type: GrantFiled: July 28, 1986Date of Patent: January 5, 1988Assignee: L. Schuler GmbHInventors: Alfred Bareis, Karl Dangelmaier, Horst Pfisterer

Patent number: 4656817Abstract: A rotating, indexable carousel-like apparatus for retaining lead frame containers for use in combination with a singulation press which severs a reel of lead frames and progressively loads the lead frames into the containers. The carousel-like apparatus can accommodate multiple lead frame containers and comprises a baseplate, circular container holder, lead frame guide means and indexing means. Also, there are means to ensure container retention within the apparatus. The apparatus includes means which raise the baseplate and container holder to a loading position and lower them to an indexing position. The apparatus will automatically index to the next loading position when a container is fully loaded. The apparatus includes means which monitor both carousel position and lead frame position and will inhibit press operation if either the apparatus, lead frames or containers within the apparatus are misaligned.Type: GrantFiled: January 10, 1986Date of Patent: April 14, 1987Assignee: Advalloy, Inc.Inventors: William M. Keady, Frank Iseger, Barry Maidment

Patent number: 4543864Abstract: A stacking conveyor is provided for receiving thin product slices moving along a horizontal path and placing a plurality of slices in stacks of predetermined configuration. One embodiment of the stacking conveyor includes a conveyor belt carried on a fixed position frame and is oscillated to receive a predetermined number of slices forming a stack and then revolved to discharge the formed stack. A second embodiment of the stacking conveyor includes a conveyor belt carried on a movable frame that is reciprocated to receive a slice while moving in one direction and then discharging the slice while moving in the opposite direction. Each of the two embodiments is adapted to be mechanically coupled with an apparatus forming the slices to either revolve the conveyor belt or to displace the conveyor belt at the same speed as the slice being received.Type: GrantFiled: October 7, 1983Date of Patent: October 1, 1985Assignee: J. E. Grote CompanyInventors: Thomas A. Hochanadel, Robert J. McInerney

Patent number: 4474092Abstract: An apparatus and method are provided for receiving products, such as stacks of sliced luncheon meat, in an intermittent flow pattern, for conveying the products in two generally parallel paths at two different flow rates, and for merging the two generally parallel paths into a single path through which the products flow on a non-intermittent basis. The two generally parallel paths have a fill mode during which an intermittent grouping of products are received onto the conveyor path, as well as a feed mode during which the intermittent grouping of products are fed in a continuous flow to a merging device. When one of the conveyor paths is in its fill mode, the other conveyor path is in its feed mode, and vice versa. The speed of each conveyor path during its fill mode is greater than that during its feed mode.Type: GrantFiled: April 21, 1983Date of Patent: October 2, 1984Assignee: Oscar Mayer Foods Corp.Inventors: Timothy G. Mally, Carroll P. Hartl, Daniel L. Orloff

Patent number: 4474093Abstract: Stacks of superimposed paper sheets are formed from a succession of layers each of which contains a given number of groups of sheets. One or more layers which contain a first number of groups can be followed by one or more layers containing a different second number of groups so that a stack can contain layers which, in turn, contain different numbers of groups and hence different numbers of sheets. The number of sheets in each stack and in each layer is a whole multiple of the number of sheets in a group. If the average number of sheets in a series of successive stacks is to deviate from a whole multiple of the number of sheets in a group, successive stacks contain different numbers of sheets; each such number is a whole multiple of the number of sheets in a group but the total number of sheets in the series of stacks divided by the number of stacks which form the series can deviate from such whole multiple.Type: GrantFiled: May 25, 1983Date of Patent: October 2, 1984Assignee: E.C.H. Will (GmbH & Co.)Inventors: Siegmar Neubuser, Peter Dose, Friedhelm Herrig

Patent number: 4433599Abstract: In an apparatus for stacking sections separated from an intermittently fed web of sheet material, successive sections are held by clamping means and transferred to the upper arm of a first suction belt conveyor having suction holes which are at a spacing larger than the length of each section and attract the trailing end thereof. A second suction belt conveyor with suction holes at the same spacing overlaps the first conveyor and takes over the sections with its lower run by attracting the leading ends. An intermittently operatively stacking conveyor under the second belt conveyor has the sections deposited thereon by means for withdrawing the sections from the second belt conveyor.Type: GrantFiled: October 21, 1981Date of Patent: February 28, 1984Assignee: Windmoller & HolscherInventors: Friedhelm Mundus, Fritz Achelpohl

Patent number: 4407628Abstract: A car on tracks behind the knives of a shear machine, has a section for receiving product cuttings when the car occupies one position on the tracks, and means are provided for receiving scrap cuttings when the car is moved to another position, the car being capable of additional movement on the tracks to a position to the rear of the machine for convenient disposal of cuttings carried by it. Work support carried by the car, supports work prior to shearing and, when possessed of magnetic qualities, will magnetically grip the work and enable adjustment thereof for shearing, by movement of the car. In lieu of magnet work supports, roller supports may be provided, and such roller supports may be power driven.Type: GrantFiled: October 30, 1978Date of Patent: October 4, 1983Assignee: Canron CorporationInventors: Eugene W.
