Abstract: The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.

Abstract: A self-propelled apparatus for the seaming of roof assemblies for a building structure, wherein the apparatus includes multiple belt components configured parallel to one another around the same set of horizontal rollers for the alignment of panel edges in order for engagement of such horizontal rollers to perform the seaming procedure is provided.

In addition, the inventive multiple belt-drive apparatus exhibits a much lower potential for slippage during use than an apparatus utilizing multiple rollers to apply proper force during a seaming operation.

Abstract: A process to perform a flaring operation on a rotating electrical device (stator) designed with a number of these spaced axially oriented splines around its perimeter. The design of the stator requires that these perimeter splines possess a flared outer end, creating a rounded cavity contour between adjacent splines to effectively retaining the stator winding in place. The method of this invention reduces damage to the stator windings and allows more wire fill during the manufacturing process.

Abstract: A hand held, sheet metal forming tool for siding installation. A main frame comprises a base and an integral, semi-circular, ambidextrous handle. The operator simply pushes the tool along siding to bead or form it by grasping either end of the handle with either hand. A pair of spaced apart, cooperating press rollers press against opposite sheet sides. A deforming pattern defined in the upper roller and a mating deforming pattern that is slightly offset in the lower roller captivate and form siding sandwiched therebetween. An offset admission throat is formed at each end of the guide channel to ease sheet insertion. Siding entering either throat is captivated within a bifurcated guide channel longitudinally coextensive with the frame that preserves alignment. The guide channel comprises intersecting vertical and horizontal guide slots. As the tool moves, the upturned siding edge slides within a vertical guide slot, maintaining spacing and alignment.

The roller is journalled for rotation on an arm pivotally carried by a slide which is moved by a drive cylinder along a lineal path generally parallel to the fold line of the portion of the flange to be prehemmed. As the slide moves linearly the arm is pivoted to move the roller transversely by a follower carried by the arm and received in an elongate cam track having a portion contoured to impart pivotal movement of the arm to cause the roller to follow the desired path of travel substantially parallel to the fold line of the flange for prehemming the flange by bending it to an acute included angle relative to an adjoining portion of the panel.

A reversible switch is connected to energize and deenergize the motor, and a directional switch safety guard is associated with the switch to limit its movement between an "off" position and either one of two "on" positions, depending upon the positioning of the guard.

Abstract: The open ends of a flat tube are closed by rolling together the edge portions of the wide, opposing sidewalls of the tube by means of two flanging rolls successively guided over these edge portions in opposite directions. One of the flanging rolls makes a longer pass than the other. The edge portions thus rolled closed are then welded to one another in a semi- or fully-automatic TIG process. The result is a clean, symmetrically shaped radiator element.
