Patent DE-19801259-A1 (DE)
Title: Continuous winding of indigo dyed cotton yarns
Inventor: EIBEL JOACHIM DR
IPC: B65H55/04
Filed: 1998-01-15
Abstract: For the continuous winding of indigo-dyed cotton yarns, the feed speed of the cotton yarn is set by the rotary speed of a previous feed unit (10). Changes in yarn tension are registered shortly before the fixed point (5) of the direction change, in the reciprocating yarn guide action, to be converted into a rotary speed change signal for the drive motor (8) of the grooved roller (7) which gives the oscillating movement to the yarn winding guide. Periodic yarn tension changes, through the reciprocating yarn guide movements, are withheld from the rotary speed change signal. The rotary speed change signal remains constantly unchanged within a window with an upper and lower yarn tension threshold value, which can be breached by regular and periodic yarn tension changes.  The feed speed remains the same on a constant difference between the mean value of the upper and lower values and their levels, and the leading feed unit (10) is controlled at a constant speed. The cotton yarns are drawn by the feed (10) as a band of warps (41) from a warp beam (1), to be separated after the feed (10) to pass separately to the winding points (2) for winding into separate bobbins (9). The separate yarns at the sides of the band of warps can be deflected away to be wound into separate bobbins, while the yarns at the center of the band are wound on to a smaller warp beam. The separate yarns have temporary speed movement changes in their paths to the winding points by an intermediate yarn storage system which alters the yarn feed lengths. An Independent claim is also included for a bobbin winding assembly, with a yarn tension sensor linked to a converter to generate electric signals to be used by a control (15) to set the rotary speed of the drive motor (8) for the grooved roller (7) to the speed of the feed (10). Preferred Features: A filter separates out signals relating to periodic yarn tension changes, and an intermediate yarn storage system can be positioned in the yarn movement path between the feed and yarn tension sensor.

Patent DE-19813165-A1 (DE)
Inventor: KLICPERA UDO
IPC: B24B1/00
Filed: 1998-03-25
Abstract: The invention relates to a method and device for machining out of round contours by using a cone-shaped or truncated cone-shaped tool which is rotationally mounted on a spindle. The spindle is arranged at a certain angle in relation to the work piece axis on which the contoured work piece is mounted. During machining, the tool pivots around at least one first pivoting axis which deviates from the spindle axis. Alternatively, the work piece can be correspondingly moved, and the tool can remain oriented in the same position. The tool and the work piece can also undergo a corresponding movement since it is simply a matter of relative movement between the tool and the work piece. In addition, the invention relates to a device for carrying out said method.
