Claim Text:
1. A device for employment in a machine tool, including: a first unit, a second unit connected to the first unit, wherein the first unit is rotatable around a rotational axis relative to the second unit, a motor spindle connected to the second unit, a line feed-through extending along the rotational axis from the first unit into the second unit, lines extending from the interior of the first unit through the line feed-through as well as through the second unit into the motor spindle, and line guiding device formed in the first unit and serving for guiding a part of the lines disposed in the first unit immediately in front of the line feed-through, wherein the line guiding device is formed in a plane oriented perpendicularly to the rotational axis, and wherein the line guiding device feeds the lines upon rotation of the second unit with respect to the first unit such that twisting of the lines in the region of the line feed-through caused by the rotation is avoided or reduced, wherein the line guiding device can be guided back and forth upon rotation of the second unit with respect to the first unit between a first state, in which the line guiding device forms an arcuate segment, and a second state, in which the line guiding device forms a spiral.
