HUYS delivers custom-made machinery for clients’ every requirement. The basic version of the SIGMA warper covers as many application areas as possible. In addition the equipment is capable of satisfying all specific customer requirements with appropriate options.

The newly conceived and unique forward beaming operation eliminates any friction on the yarn sheet. This results in an unsurpassed beam quality which is particularly important when processing delicate yarns. Conventional beaming is also available whenever existing beam handling logistics should be preserved.

To provide the best possible beam quality HUYS broke new ground. The beamer of the SIGMA section warper can be positioned at the side of the creel. This results in the most efficient beaming operation by eliminating deflecting rolls and without having to reverse the warping direction. This beaming operation is particularly important when processing delicate yarns.

This forward beaming operation has a number of advantages:

- Friction between the yarns and the deflecting rolls is avoided.

- Crossed yarns will open up during beaming.
- The graphic touch screen terminal is within easy reach of the operator during warping and beaming.

The yarn build up is monitored right from the start of the warping process. All the sections are built in exactly the same way for an absolutely uniform warp quality.
After entering the basic warp data in the operator terminal, the machine defines automatically the initial reed headstock feed. This feed is controlled by the electronics system in the first section and adapted to the yarn behaviour for a perfect warp build. The feed pattern of the first section is memorised and reproduced in all following sections. The productivity is unsurpassed since the feed sensoring technology is contact-less and does not require any measuring stops.

The self compensating tensioners on the HUYS creels keep the yarn tension constant, independent of speed and package size.

The reed headstock movement is driven by a high precision stepper motor with traction on a steel reinforced toothed belt. This belt is absolutely maintenance-free.

Thus, an absolute cylindrical package build is obtained since:

• All the threads have exactly the same length
• All the threads are wound on under constant tension

• The sections fit together with ultimate precision

The machine is operated with multilingual operative prompting. The graphic touch screen operator terminal is the state of the art in man machine interface and is menu driven for all entries.

Hierarchic password protection, extensive help functions and automatic calculation of most of the process parameters guarantees a safe and reliable operation.

The machine can be operated within a few days and without any special training. The display text is available in more then 10 different languages.

All the data of a produced warp can be stored in a database for later use. This way a repeat job can be started within seconds.

Information messages assist continuously the operative. Messages appear whenever an out-of limit parameter is entered. Service and fault displays stating causes and indicating remedies are generated automatically.

Warping unit

• Waxing unit for uniform wax application to the yarns.

• Inversion bar for warping large symmetrical color patterns without recreeling. This way only half the repeat needs be creeled.

• Single or double ionization bars on the warping headstock for the elimination of static charges.

• High power drives.

• Increased section widths up to 700 mm.

Beaming unit

• Hydraulic beam loading and doffing. The beams are lifted in and out hydraulically without physical effort. Mounting, centering, as well as shifting the beam supports laterally are all powered.

• Pressing device for high winding densities. Optimum hardness is achieved on the weaver’s beam with minimal warp tension.

• Large beam diameters or technical textiles often call for very high beaming forces. For this the beamer may be provided with a number of high-power drive or dual drive (with a drive on each side)

• 1.1 and 1.25 meter beam flange diameter.

The SIGMA section warper is built using standard mechanical and electrical com-ponents. Consumer parts such as brake linings, bearings, belts, etc… are from the most reputed suppliers and readily available worldwide. As a result, the machine has a minimal operating and service cost. The inter-vention cost is practically reduced to zero.

The machine operation is controlled by standard electronic building blocks. The operator terminal interface uses a Windows software platform. This way, the machine can very easily be provided with a modem for rapid, low-cost remote diagnosis. Standard interfaces can be used for data acquisition or integration in plant supervision systems.
