Patent number: 8800338Abstract: An apparatus is disclosed for the manufacture of a coil spring from a wire. The apparatus comprises first and second tools for contacting the wire prior to, and/or during, deformation of the wire into a coil spring. The apparatus includes means for applying an electrical potential difference between the first and second tools such that an electric current is caused to flow through at least part of the wire during use.Type: GrantFiled: December 15, 2009Date of Patent: August 12, 2014Assignee: Springform Technology LimitedInventor: Ian James Whitworth

Publication number: 20100043909Abstract: It, as shown in FIG. 11, is provided with a feed roller 31 that is movable, rotates the spiral coil 11 passing through punched holes 3a of the bundle of paper-sheets 3, and guides the spiral coil 11 to feed it toward a coil advance direction, a screw guide 49 at a movable and adjustable side that guides and conducts a forward end of the spiral coil 11 fed by the feed roller 31 toward the coil advance direction into the punched holes 3a thereof, and a control part that receives diameter-of-coil-setting information for setting a diameter of a coil of the spiral coil 11 and controls positions of the feed roller 31 and the screw guide 49 based on the diameter-of-coil-setting information. Such a configuration enables the feed roller 31 and the screw guide 49 to move to the guided positions of the spiral coil 11 indicated by the diameter-of-coil-setting information. Accordingly, it is possible to pass the spiral coils having the different diameters thereof through the holes of the bundle of paper-sheets stably.Type: ApplicationFiled: February 19, 2008Publication date: February 25, 2010Applicant: MAX CO., LTD.Inventors: Toru Yoshie, Kazuhiko Kishi

Patent number: 7493924Abstract: An apparatus for processing chain link fabric including a welding assembly and/or a compressing assembly. The welding assembly is configured to weld together wire-end portions of the chain link fabric. The welding assembly includes a guiding assembly having a finger and a cam, which are configured to restrict the movement of the wire-end portions while the welding assembly welds them together. The finger and the cam are configured to move relative to the wire-end portions both before and after the wire-end portions are welded together. The compressing assembly is configured to compress the wire-end portions after they are welded together. The compressing assembly includes a stabilizing assembly having a stabilizing die, which is configured to interface with the chain link fabric and to restrict the movement of the welded wire-end portions while the compressing assembly compresses the welded wire-end portions.Type: GrantFiled: May 17, 2005Date of Patent: February 24, 2009Assignee: Bergandi Machinery CompanyInventors: Jose G. Garcia, Scott C. Barsotti

Patent number: 6942441Abstract: Sheets of paper are commonly held together with a spiral coil, which coil is inserted by a machine with at least one rotating spindle thereon. The spindle receives a spiral binder in a male to female relationship. As the spindle rotates the spiral binder, the spiral binder feeds into a stack of sheets having the appropriate apertures to receive the spindle and bind the pages together.Type: GrantFiled: September 20, 2002Date of Patent: September 13, 2005Inventor: Peter N. Lathrop

Patent number: 6851907Abstract: A binding machine and method for spirally binding a sheaf of papers into a book uses an adjustable speed drive to rotate a flexible plastic spiral element into respective holes in the book. The book has a plurality of holes in a row adjacent one edge of the book to receive the leading edge of the spiral bonding elements. A cylindrically shaped mandrel is spaced apart from a glidable block. The plastic pre-formed spiral binding element is fed onto the mandrel from the distal end thereof, with the leading edge of the binding element facing and spaced apart from the book. A pair of leading edge spreaders, one of which has a guidance groove, engages the plastic spiral to spread its coils just enough to permit it to enter the successive holes of a sheaf to be bound. A trailing spreader at the opposite end insures that the last hole is accommodated with a portion of the spiral coil.Type: GrantFiled: November 2, 2001Date of Patent: February 8, 2005Assignee: Spiel Associates, Inc.Inventors: Norton Spiel, Robert Dorishook

Patent number: 6823901Abstract: Chain link material for use in fences and other various applications are formed with flattened end portions so as to improve the handling and safety characteristics thereof. The flattened end portions of the chain link fence are formed by bending, trimming, welding together and then painting cut ends of the wire forming the chain link material. This bending, trimming, welding and painting is performed in a series of assemblies held on one or both sides of a chain link material being indexed through a weaving machine. The series of assemblies are moveable into and out of contact with the cut ends of the wires in the chain link material so as to bend, trim, weld together and paint the welded together ends.Type: GrantFiled: June 7, 2002Date of Patent: November 30, 2004Assignee: BMCI, Inc.Inventor: Jose G. Garcia
