Traction means tensioner, vibration welding device having a traction means tensioner as well as production method for a traction means tensioner

摘要

With the traction mechanism tensioner, a traction mechanism having at least two ends is tensionable. The traction mechanism tensioner comprises a first fastener, a second fastener and a coupler. The first fastener has a first fastening portion at which the first end of the traction mechanism as fastenable. The second fastener has a second fastening portion at which the second end of the traction mechanism is fastenable. The coupling means couples the first and the second fasteners to each other so that the first and the second fasteners are movable with respect to each other and their movability is at least restricted on one side. Further, the first and the second fasteners are pre-tensionable with respect to each other via at least one spring element.
