Highlights

The integrated system solution for automating the beam frame offers:

• Interlock and safety functions on the machine through digital I/Os
• Acquisition/preparation of all relevant actual value parameters
• Control of drum and beam drives and roller unit
• Position control system for cross-feeder and linear drum movement
• Closed-loop control of layer thickness
• Definition of process parameters
• Beam logging
• Shift data acquisition.

Область применения

The warping frame is used to draw off a large number of individual threads from bobbins and wind them onto warp beams for use as a starting product for knitting or weaving machines. The special feature of the warping frame is that the warp yarn is wound with an absolutely uniform distance and tension, thus ensuring the consistency of further processing.

There are two parts to the production process:

• Warping
  The warp yarn, which is fed across the roller unit from the bobbin creel, is wound onto the drum in sections. A cross-feeder ensures that the yarn is wound correctly as the drum rotates. The roller unit produces the necessary yarn tension.
• Beaming
  The yarn, which has been wound in sections, is wound onto the beam by the drum. The beam is moved in order to tension the yarn. The drum drive uses a brake to generate a counter-torque.
