Patent number: 4768364Abstract: A continuous-acting take-up, coiling, cut-off and spooling machine is adapted for use with continuously producing metal casting equipment that casts metal rod or strip stock at a constant rate, and which produces the cast rod or strip stock at a relatively constant velocity. The machine coils, cuts-off, temporarily accumulates and spools or packages determinate lengths of the rod or strip stock formed by the casting apparatus. Driven rollers receive the leading end of the rod or strip stock. The rod or strip stock is cut to predetermined, desired lengths while still in motion so as to not disturb the feed velocity. Free-wheeling rollers forcibly impart a slight curvature and simultaneous axial displacement to the rod or strip stock along its length, forming coils or convolutions of helical configuration, which are deposited by gravity, over a turnably driven reel carried on a tiltable turntable.Type: GrantFiled: November 4, 1986Date of Patent: September 6, 1988Assignee: Wyrepak Industries, Inc.Inventors: Joseph J. Kovaleski, Gordon L. Bauer

Patent number: 4726209Abstract: A method of continuously forming edgewise wound cores from a strip of generally thin ferromagnetic material at at least one operation station therefor having a means for receiving the cores. The receiving means includes a pair of separable means adapted for association with each other and separation, and a set of supporting means is operable generally in one of the separable means for movement between retracted and protracted positions, respectively. In the practice of this method, the continuous strip is deformed generally edgewise thereof into a plurality of helical convolutions at the at least one operation station. The separable means are separated from each other, and thereby the operation of the supporting means toward the protracted positions thereof is effected.Type: GrantFiled: December 11, 1986Date of Patent: February 23, 1988Assignee: General Electric CompanyInventor: Gustave F. Wiedemann

Patent number: 4643012Abstract: Apparatus for forming edgewise wound cores from a continuous strip of generally thin ferromagnetic material has means operable generally for deforming the continuous strip into a plurality of generally helical convolutions thereof, and means is arranged for receiving the deformed helical convolutions from the deforming means and for accumulating the deformed helical convolutions into a generally axial stack thereof. The receiving and accumulating means includes a pair of relatively movable means associated with each other and operable generally for separation, and a set of means operable in one of said relatively movable means toward a preselected position for supporting at least some of the deformed helical convolutions received on said one relatively movable means when the other of said relatively movable means is separated therefrom, respectively.Type: GrantFiled: October 12, 1984Date of Patent: February 17, 1987Assignee: General Electric CompanyInventor: Gustave F. Wiedemann

Patent number: 4331015Abstract: A tube bending machine comprises a tube bending mechanism per se for bending a front portion of a tube inserted therein and fluid operated units for moving a mandrel in axial direction into the tube to be bent and for withdrawing the mandrel through a rear end of the tube after bending. A tube magazine is located to one side of the bending mechanism and a tube depositing station for receiving the bent tube is located at the other side thereof.Type: GrantFiled: March 3, 1980Date of Patent: May 25, 1982Assignee: Benteler-Werke AGInventors: Hubertus Benteler, Wolfgang Streubel, Egon Olszewski

Patent number: 4311031Abstract: A pipe bending machine has a pipe bending mechanism which receives lengths of pipe to be bent from a pipe magazine located laterally of one side of the mechanism. A pipe transfer device is interposed between the bending mechanism and the magazine and transports pipe length from the magazine to the bending mechanism, for which purpose it is so constructed that it can pivot in a plurality of mutually inclined planes.Type: GrantFiled: July 20, 1979Date of Patent: January 19, 1982Inventor: Rigobert Schwarze

Patent number: 4090383Abstract: There is disclosed a device for extracting the end portion of wire rod from a laying guide of an Edenborn coiler arranged downstream of a wire rod rolling mill. The device includes an extractor cylinder idly supported by the laying cone of the coiler so as to be substantially stationary during rotation of the coiler or to slightly rotate in a direction opposite to that of the coiler. The cylinder has a diameter slightly smaller than that of the formed coils and a length such as to comprise at least one turn of the deposited coils. When the end portion of the wire rod has leaved the rolling mill and is no more dragged by pinch rollers or the like at the output of the rolling mill, the speed thereof decreases due to friction against the walls of the output guide located between the rolling mill and the coiler.Type: GrantFiled: February 24, 1977Date of Patent: May 23, 1978Inventor: Giulio Properzi

Patent number: 3996778Abstract: A loader and unloader for a plate roll machine has an extensible boom extending generally horizontally over the plate rolls of the machine from a stationary support frame to which the boom is pivoted at one end for vertical movement over the rolls. The boom telescopes through the action of a hydraulic cylinder from a retracted position in which the free end of the boom overlies the plate rolls to an extended position in which such free end extends outwardly beyond the plate rolls. Additional fluid cylinders pivot the boom vertically. A plate support carriage is pivoted to the free end of the boom for fore-and-aft tilting movement. The carriage has one or more rollers extending lengthwise of the boom for engaging and supporting a rolled plate at its upper inside surface. The boom is retracted and positioned vertically for supporting the plate as it is rolled in the plate rolls.Type: GrantFiled: December 8, 1975Date of Patent: December 14, 1976Assignee: Steel Structures, Inc.Inventor: Charles H.
