Abstract

The invention relates to an arrangement in a machine tool having a raw-material gripping or releasing device, a material machining tool (6), and a stirrup device (7) having mutually opposed legs (7a, 7b) intended for coaction with the raw material (3), wherein the arrangement is effective in moving the raw material (3) axially in relation to the gripping or releasing device (2) when the raw material (3) is loosened therein. The distance (a) between the mutually facing surfaces (7a', 7b') of the legs is adapted to correspond to the distance (c) between the outer surfaces (3c, 3d) of the material, with small selected tolerance limits. The surface parts (7a', 7b') of the mutually opposed legs facing towards the material have a longitudinal extension (d) related to the surface parts (3c, 3d) of the material such that tipping of the material (3) caused by loosening the material in the gripping or releasing device (2) will generate increased force interactions between the mutually opposed surface parts (7a', 7b') and the surface parts (3c, 3d) of the material; wherein the increased force interactions create slip-free coaction between the surface parts (7a', 7b') and the surface parts (3c, 3d) of the material, so as to enable the material (3) to move axially in relation to the gripping or releasing device.
