Patent number: 6944951Abstract: An apparatus for making reinforcing cages, the apparatus having: a frame; a former adapted to receive a plurality of longitudinally extending reinforcing rods; a bed attached to the frame, wherein the former rests on and is able to rotate relative to the bed; a drive for rotating the former; a loading module located adjacent to the former; a shuttle mounted on the loading module for longitudinal reciprocal movement towards and away from the former, wherein the shuttle feeds reinforcing rods into the former by moving towards the former, and withdraws the reinforcing rods from the former by moving away from the former as a reinforcing band is positioned around the reinforcing bars; and a rotatable cage holder adapted to hold a reinforcing cage during construction of the reinforcing cage, the cage holder being adapted to substantially prevent twisting of the reinforcing rods which form part of the reinforcing cage.Type: GrantFiled: September 26, 2001Date of Patent: September 20, 2005Inventor: Wayne Barden

Patent number: 6915572Abstract: Method and apparatus for the continuous manufacture of structural members, in which two parallel, flat wire mesh mats comprising longitudinal and transverse wires intersecting with each other and welded together at the points of intersection are advanced on a production line and between the wire mesh mats is introduced an insulating body, whereupon the straight link wires are passed through the insulating body and with their ends welded to the wire mesh mats, so that the latter are held a predetermined distance apart, wherein first an endless, coherent web of insulating material is produced from individual insulating panels and advanced and then the insulating body is cut off this web of insulating material in a selectable length.Type: GrantFiled: October 5, 1999Date of Patent: July 12, 2005Assignee: EVG Entwicklungs-U. Verwertungs-Gesellschaft mbHInventors: Klaus Ritter, Ingrid Ritter, Gerhard Schmidt, Gerhard Ritter

Patent number: 6874233Abstract: Methods and systems are provided for the continuous coating and fabrication of spiraled steel rebar product for concrete structures. Specifically, methods and systems are provided by which linear uncoated rebar is supplied to a polymeric (preferably, epoxy) powder-coating unit whereby a substantially uniform coating layer of a polymeric material is applied onto the uncoated rebar to form a linear coated rebar; and thereafter the linear coated rebar is bent into a spiraled steel rebar product. The bending unit employed to bend the linear coated rebar includes a series of bending wheels having separated upstream and downstream bending wheels and a central bending wheel which is disposed between and below these upstream and downstream bending wheels. By bringing the linear coated rebar into contact with the series of bending wheels, the rebar may be bent gently into spiraled steel rebar product without damage to the polymeric surface coating.Type: GrantFiled: September 29, 2003Date of Patent: April 5, 2005Inventor: Richard D.

Patent number: 6763589Abstract: Disclosed is a process for the industrial manufacture of a formwork panel in a continuous manner. In this process, a corrugated reinforcing metal core is manufactured in the form of a continuous metal core band. The metal core band is supplied onto a main conveyor. Simultaneously, a mixture of components that react with each other to make an insulating foam, is prepared and continuously injected at the inlet of the main conveyor. The foam that is being formed and expands along the main conveyor, is compressed so as to form to a continuous main body band having a given height and given thickness. This continuous main body band incorporating the continuous metal core band. Last of all, the continuous main body band and the continuous metal core band incorporated therein are cut at the outlet of the main conveyor to obtain the requested panels.Type: GrantFiled: January 31, 2002Date of Patent: July 20, 2004Inventor: Serge Meilleur
