  • Publication number: 20040074356
    Abstract: A process of, and apparatus for, the feeding of elongated strips of magnetic core stock material to successive stations of a multi-station die assembly for forming successive lamination blanks into individual magnetic core lamina is disclosed. To properly align the material with the corresponding dies, relative motion between each pair of successive lamination blanks is facilitated while those blanks are still joined. This relative motion is provided by significantly weakening the material in the region between two successive lamination blanks. In the illustrated preferred embodiment, the provision for relative motion includes removing the majority of the material interconnecting two adjacent lamination blanks without separating the individual lamination blanks from one another by use of an additional punch and die at the initial station for partially severing the strip between adjacent lamination blanks.

  • Patent number: 6361639
    Abstract: A method for manufacturing an index divider sheet assembly adapted for feeding into ink jet printers and the like for a printing operation on the sheet body and/or the index tab of the assembly. The assembly includes a divider sheet having a tab extending out of one edge and a reinforced binding edge flap. The divider sheet can be manufactured from ink jet receptive top-coated white cardstock. A guide strip along the tab edge assists the assembly being fed and passing through the printer despite the presence of the tab. The binding edge flap is folded over onto the body of the sheet and held thereon to reduce the width dimension of the assembly so that it can be fed into and passed through the printer. After passing through the printer, the guide strip is removed and the flap is unfolded.

  • Patent number: 6026721
    Abstract: A method for manufacturing a first valve disc and a second valve disc for use in a compressor having a longitudinal axis and several cylinder chambers surrounding the axis is described. The method includes the steps of: providing a sheet of resilient valve material; stamping a through-hole having several extended openings out of the sheet to produce the first valve disc with several arms; and stamping several arch-shaped openings out of the sheet spaced around the through-hole corresponding to each of the extended openings of the through-hole to produce the second valve disc. Thus, an economical manufacturing method for obtaining a set of suction valve and discharge valve discs from a common surface area of sheet material is described. A small valve disc is obtained by stamping out the central portion of a larger valve disc. The total quantity of sheet material required for making a set of two kinds of valve discs thereby is reduced.

  • Patent number: 5531145
    Abstract: A method for producing a mini chip card out of a standard card having an embedded semiconductor chip uses a punching die with cutting edges defining the outer contour of the mini chip card. The punching die is adjusted relative to the standard card and with respect to contact surfaces of the embedded semiconductor chip so that the edges of the punching die are at a predetermined distance from the contact surfaces. The punching of the standard card is performed in this adjusted position so that the contact surfaces are in a reference position with respect to the outer contour of the mini chip card. The punching forms the mini chip card in the correct position in the standard card. The mini chip card may initially remain connected to the standard card by thin bars between the cards.

  • Patent number: 4681001
    Abstract: Polygonally-shaped blanks useful in making products such as can parts are formed by dividing a relatively wide web of material into a plurality of relatively narrow strips, each strip having longitudinal edges delimited by scroll lines formed from a plurality of straight scroll line sections. The strips can be arranged parallel to a longitudinal axis of the web or at an angle relative thereto. It is also possible to divide the strips into individual blanks at a scrolling station or at a remote can making station. The polygonal shape of the blanks permits them to be designed so as to compensate for earing caused by the anisotropy of the material from which the web is made. Various punches and slitting arrangements can be employed to perforate the web and to longitudinally and laterally cut it so as to form the strip and/or blanks therefrom.

  • Patent number: 4128320
    Abstract: A method of producing stereoscopic film from standard 35 mm film is described in which the standard 35 mm is longitudinally cut in half. Selected sprocket holes in each half are enlarged to provide a series of locating holes at regular intervals along the film. Each locating hole enables a corresponding pair of stereoscopic film frames on the film to be located in a viewing position. Also described is a viewer for viewing the stereoscopic films. The viewer incorporates a locating finger which engages each locating hole in turn to locate and hold the film steady while viewing. The viewer includes a reciprocating drive means for driving the film. The locating finger is withdrawn from a locating hole when the drive means performs its forward stroke and the forward stroke is limited when the finger engages the next hole. The finger remains engaged with the next locating hole during the return stroke of the drive means thereby preventing any inadvertant movement of the film during the return stroke.
