Conversions for Projectile Weaving Machines
Solution for the conversion from mechanical to electronic warp let-off system.
AN EXAMPLE OF THIS SOLUTION FAMILY:
ELECTRONIC WARP LET-OFF FOR FULL AND HALF WARP BEAMS
DESIGNED FOR PROJECTILE WEAVING MACHINES
OVERVIEW
Electronic let-off motions keep the warp tension at a constant level from full to empty beam; undesirable tension peaks are leveled out. The warp let-off requires no maintenance, facilitates operation and has a positive influence on fabric quality.
Today we can provide a conversion set not only for single but also for half width warp beams. Normally the half width warp beams execution are equipped with a mechanical differential gear to drive the second warp beam an equal tension on both warp beams are not ensured. With our conversion set we can replace the mechanical differential by a second warp let-off.
The speeds of both warp beams are controlled individually in accordance with the left and right control signals, respectively. The warp tension is measured by an absolute sensor independently of the backrest roller.
KEY ADVANTAGES
- Simple handling
- Maintenance-free
- Customized adaptation of let-off device with gear combination
- Varied parameter programming for quality optimization
- Higher fabric quality
