Abstract: A winding device suitable for winding at least one strip on a mandrel. According to one embodiment the winding device includes a pressure assembly configured to press a strip against the surface of the mandrel when winding the strip. The pressure assembly comprises a first pressure unit which is coupled to and rotates together with the mandrel from a first winding position to a second winding position while the first pressure unit presses on the strip. The pressure assembly further comprises a second pressure unit that is attached to the first pressure unit, and that is configured for pressing on the strip when the first pressure unit reaches the second winding position, allowing forward movement of the strip in the winding direction when the mandrel rotates.

Abstract: A drawing support for a metal sheet drawing machine. In one implementation the drawing support is constructed of a plurality of plates positioned in series one after the other and coupled together so that at least a portion of the plurality of plates are compressed one against the other. In one implementation each of the plurality of plates has a window through which metal sheet to be drawn may pass, and a holder for holding the metal sheet when it is drawn.

Abstract: A fixed support for a metal sheet drawing machine. In one implementation the fixed support includes a window through which metal sheet to be drawn passes, and a holder which holds the metal sheet within the window as the metal sheet is drawn. The fixed support is stationary in relation to the drawing machine and includes a suspending structure that maintains a base of the fixed support a distance from any other surfaces during the sheet drawing process.

Abstract: An apparatus for drawing a metal sheet. In one implementation the apparatus includes a fixed head having a first window through which the metal sheet to be drawn may pass and a first holder for holding a first portion of the metal sheet within the first window during a drawing process. The apparatus also includes a moving head that is moveable relative to the fixed head. The moving head has a second window through which the metal sheet to be drawn may pass and a second holder for holding a second portion of the metal sheet within the second window during a drawing process. A support assembly is attached at one end to the fixed head and extends longitudinally through the second window of the moving head. The support assembly forms a part of an actuator assembly that is operable to situate the moving head in different and fixed longitudinal positions relative to the fixed head prior to a drawing process.
