A thread spooler includes a plurality of spool units, each of which includes a thread defect sensor of a defect classification device which reacts to defects of the thread to be wound up. A large number of sets of predetermined operational parameters of the spool units and/or the defect classification devices can be recorded by a central input device into a central memory which stores all these data simultaneously. Each of the spool units includes a decentralized memory, into which one of the centrally stored operational parameter sets can be loaded individually for each spool unit by a call-up switch. A central control determines for respective groups of spool units a predetermined sequence, in which the operational parameter sets can be called up by the spool units. The classification device determines the thread defect, preferably individually for each spool unit, and indeed respectively referred onto the last wound gauged length of the thread. The winding device of the spool unit is operated with the maximum possible rpm. The rpm is reduced if a predetermined maximum thread speed is reached.

Thread spooler

In a draw-bar mechanism for moving the collet of a chuck or the like on a spindle of an automatic turning machine toward its axial clamping position and for thereafter closing the collet more slowly with greater force about a tool or workpiece to be clamped, motion is transmitted from an actuating sleeve to a draw bar or like control member by spherical thrust members movably confined between three faces obliquely inclined relative to each other. A first face is fixed relative to the spindle assembly and has one section parallel to the axis and another axially contiguous section obliquely inclined relative to the axis, the two sections merging in an exposed edge. A second face is fixed relative to the control member, and the third face is fixed relative to the actuating sleeve and has two axially consecutive sections obliquely inclined relative to each other. The faces are dimensioned and shaped in such a manner as to permit tilting of the thrust members about the exposed edge during movement of the control member in the axial collet-clamping direction while the thrust members engage the face of the actuating sleeve.
