Patent number: 5330119Abstract: A method and apparatus for simultaneously preparing and feeding coils of strip stock into a strip processing line. Two coil support mechanisms are provided, each rotatably supporting a coil for uncoiling. A takeoff mechanism spaced apart from the strip processing line is adapted to peel a free leading end of the strip stock from a coil. The leading end is fed to a holding mechanism adapted to receive and hold the leading end in a predetermined position. A transfer mechanism is provided for successively transferring each coil support mechanism and associated holding mechanism from the takeoff mechanism to an aligning mechanism adjacent the processing line and back to the takeoff mechanism. The strip stock is moved by pinch rollers from the holding mechanism, through the aligning mechanism, and into the processing line. One coil may be prepared for feeding in the takeoff mechanism while the other coil is being fed into the processing line.Type: GrantFiled: August 12, 1992Date of Patent: July 19, 1994Assignee: Abbey Etna Machine CompanyInventors: Jose L.

Patent number: 5323949Abstract: The invention comprises a method and apparatus for handling the weld bead scarfed from the interior surface of continuous seam welded metal tube or pipe incident to its manufacture. A section of tube of predetermined length is cut from the lead and of the advancing continuous tube, having the scarfed weld bead therein, by a rotary cutter. The speed of the individual section is increased to create a gap between the individual section and the continuous tube, and a scissor mechanism severs the weld bead within the gap. The severed section of weld bead is then conveyed within the associated individual section of tube to a tube accumulation or storage area for removal and disposal.Type: GrantFiled: June 23, 1993Date of Patent: June 28, 1994Assignee: Abbey Etna Machine CompanyInventors: Lewis H. Ruple, George W. Kaase

Patent number: 5309746Abstract: A system is provided for assuring the straightness of pipes or tubes produced by a continuous seam-welded process. Following sizing, the newly formed continuous tube passes through a straightening unit and a preliminary alignment checker. The alignment checker observes the actual spatial position of the advancing tube, and the straightening unit is adjusted in response to deviations of the observed position from the predetermined desired path to deform the tube so that it conforms to the desired path. The advancing continuous tube is then severed into individual tube sections of desired length, and some or all of the sections are inspected for straightness. In inspecting for straightness the individual sections are rotated about their longitudinal axes to place the seam-weld in a predetermined position for correlating the angular attitude of the section with that of the advancing continuous tube.Type: GrantFiled: January 28, 1993Date of Patent: May 10, 1994Assignee: Abbey Etna Machine CompanyInventor: Nelson D. Abbey, III

Patent number: 5192013Abstract: The invention comprises an apparatus for removing from the outer surface the raised bead resulting from welding in the manufacture of continuous seam-welded metal tubes. A stage or travelling support block mounted for movement transversely of the advancing tube carries a pair of scarfing blades, each of which may have a plurality of cutting edges moveable seriatim into operative position. Adjusting screws operatively connected to the stage permit the stage and the scarfing blades thereon to be manually adjusted both laterally and vertically relative to the tube, and to selectively position either one of the scarfing blades for bead removal. A piston rod is connected by suitable linkage to the stage for rapidly advancing and retracting the stage upon command to move the scarfing blade into and out of operative position.Type: GrantFiled: September 20, 1991Date of Patent: March 9, 1993Assignee: Abbey Etna Machine CompanyInventors: Nelson D. Abbey, III, Timothy J. Lewandowski

Patent number: 5148960Abstract: The invention comprises an apparatus for aligning and guiding the seam of newly formed tube as it enters the welding mechanism in the manufacture of continuous seam-welded metal tubes or pipes. A rotary seam guide member having an alignment fin is mounted so that a alignment fin rollingly engages within the open seam immediately in advance of the seam welding mechanism. The seam guide member and a cooperating opposed roller guide the tube into the welding mechanism. The seam guide and opposed roller are carried within a roll stand including mechanism by which their position may be adjusted vertically and longitudinally relative to the welding mechanism, as well as rotated arcuately about the path of the tube. The seam guide member and/or the opposed roller may include insulating barriers to impede induced heating thereof.Type: GrantFiled: February 3, 1992Date of Patent: September 22, 1992Assignee: Abbey Etna Machine CompanyInventors: Nelson D.
