Abstract: A draw-in wire tip and a respective draw-in wire body each having optimized flexural strength in such a way that insertion of a draw-in wire which is composed of these two components is easily possible, even in complex tube systems.

Abstract: A draw-in wire tip with a base part, a flexible part and a head part for draw-in wires for drawing lines into tubes and cavities and the like, with the flexibility of the flexible part increasing from the base part in the direction towards the head part.

Abstract: The invention relates to an apparatus for introducing a draw wire (4) into tubes, comprising: a. a first actuating body (5) in which the draw wire (4) is guided in a sliding manner; b. a first clamping device (1, 01) that is arranged in the first actuating body (5) and that blocks and releases the movement of the draw wire (4); c. a second actuating body (6, 7) in which the draw wire (4) is guided in a sliding manner; d. a second clamping device (2, 02) that is preferably arranged in the second actuating body (6, 7) and that blocks and releases the movement of the draw wire (4); e. a telescopic tube (8, 08) that connects the first clamping device (1, 01) and the second clamping device (2, 02). Smooth introduction even in difficult situations is enabled in such a way that the telescopic tube (8, 08) is arranged to be torsionally rigid.

Abstract: The invention relates to a device for introducing a draw wire or element (4) into tubes, comprising (a) a first actuation body (5) into which the draw wire or element (4) is slidingly guided, (b) a first clamping device (1, 01) that is arranged in the first actuating body (5) and that blocks and releases the movement of the draw wire or element (4), (c) a second actuating body (6, 7) into which the draw wire or element (4) is slidingly guided, (d) a second clamping device (2, 02) that is arranged, preferably, in the second actuating body (6, 7) and that blocks and releases the movement of the draw wire or element (4), (e) a telescopic tube (8, 08) that joins the first clamping device (1, 01) and the second clamping device (2, 02). The fact that the telescopic tube (8, 08) is rotationally fixed permits a problem-free introduction, even in difficult situations.
