Energy chains, namely chain parts, in particular chain link plates, therefor and guiding parts of a guide trough for an energy chain. The chain part or guiding part comprises a formed part made from plastic, on which a functional electric circuit with a sensor function is arranged. The functional circuit comprises at least one trace conductor structure, which is formed on the formed part as the carrier of the trace conductor structure, e.g. is applied by an additive manufacturing method.

A line guiding system comprising an articulated line guiding apparatus which, for guiding supply lines between two connection points that are movable relative to each other, is curved about a deflection axis extending in a transverse direction transverse to the longitudinal direction, and a separate guiding device for guiding the line guiding apparatus along at least a section of the travel path. The guiding device comprises at least one guide strand, which is arrangeable for predefining a desired course of the section of the travel path. The line guiding apparatus comprises external profile regions, which are arranged for lying against and/or on the guide strand and are shaped with a profile shape for a transversely stabilizing guiding against or on the guide strand by projecting and/or recessed interengagement of guide strand and profile shape to counteract a lateral deviation of the movable line guiding apparatus in the transverse direction.

A winding drum for a line and/or for a line guide device which is adapted to receive and guide at least one line, wherein the drum is rotatable about the longitudinal axis thereof, wherein a first end region of the line and/or line guide device is or can be fixed to the drum and the line and/or line guide device can be wound on to and unwound from the drum by rotation of the winding drum in a winding-on and an unwinding direction about the drum longitudinal axis, wherein there is provided a drive device engaging the winding drum in order upon rotation of the drum in the unwinding direction thereof to exert a return force on the drum for rotation thereof in the winding-on direction. The drive device is in the form of a torsion spring which upon rotation of the drum in the unwinding direction is subjected to torsional stress and by virtue of the torsional stress exerts a torque on the drum for rotation thereof in the winding-on direction and the torsional stress exerts the return force on the drum.

A machining unit for use on a machining tool has a head carrier that is attachable to the machine tool and has a head carrier housing , a swivel head that is provided to swivel relative to the head carrier about a swivel head rotation axis and has a swivel head housing, a spindle head that is attached to the swivel head and has a working spindle , and a cable run that extends inside the head carrier housing to the swivel head and has a plurality of members that are arranged in succession along the cable run and are connected movably together. Adjacent members are in this case able to rotate and swivel relative to one another and each member has a central piece and a sheathing spaced apart therefrom. The central piece is connected to the sheathing via one or more connection elements.

A line guide device comprising an envelope for supply lines and an articulated support chain. One chain link has an inside projection in a first longitudinal portion and an inside cross-bridge with an extended stop face and a recess adjoining the cross-bridge in a second longitudinal portion. In the extended position, the projection of one chain link engages in the recess of the following chain link and on the cross-bridge thereof. A support chain, in which each chain link has, in its second longitudinal portion, an outside cross-connection which in the arcuate position interacts with an outside arc stop face of the first longitudinal portion and has an inside cross-connection which in the extended position interacts with an inside extended stop face of the first longitudinal portion.
