Karl Mayer, Weftloc 3 E, Working Width 4320mm, Gauge E 28

Karl Mayer, Weftloc 3 E, Working Width 4320mm, Gauge E 28

Description

  1. Overview
    1. Raschel machine with magazine weft insertion for elasthane yarns
    2. Weftloc 3 E
    3. Weftloc-fabric is high-quality bi-directional elastic raschel fabric with good recovery properties due to high elastane content, body hugging and comfortable to wear
    4. The weft carrier endlessly fills weft ends in open transport hooks; weft clamps close automatically, keeping weft ends clamped with optimum tension during the entire knitting process
    5. Patented system (patent-no. DE 37 29 344) eliminates thread tension differences; welt threads are straight and parallel adjusted
  2. Specifications
    1. Working width: 170 in / 4320 mm
    2. Gauge: E 28
    3. Standard voltage / frequency according to DIN 40960 T2 3/N/PE = 50/60 Hz 400/250 V
  3. Yarnpath (yarn directing and tensioning devices)
    1. Turnable springloaded tension compensating bars stationary, turnable diversion bars
    2. 3 separators in lower position
    3. 3 separators in upper position
  4. Pattern drive
    1. 3 pattern discs (344 mm)
    2. Directly controlled motion, 4 tempt
  5. Main drive
    1. Squirrel cage motor, electronic frequency transformer for continuous speed control, with integrated soft start and adjustable runoff, as well as inching equipment
  6. Machine control
    1. Emc, computer control system with integrated lc-display for programming and monitoring of all machine functions
  7. Take-up
    1. Four roller take-up system, drive by speed change gear box, 1 set of change gears
  8. Fabric wind-up
    1. No. 2d, centre wind-up system, electrically tension controlled by a gear motor; winding tension of the fabric is automatically kept the same during the whole winding process
    2. Maximum fabric roll diameter 20 ½ in (520 mm)
  9. Knitting elements
    1. 3 guide bars with guides, hard-chromed (1 in leads), max shogging motion 1 in (25.4 mm); both guide bars 1 and 2 form stitch
    2. 1 needle bar with compound needles (individually inserted)
    3. 1 closure bar with wire closures (1 in leads)
    4. 1 knock-over bar with knock-over sinkers (1 in leads)
    5. 1 weft thread insertion bar with weft thread insertion sinker (single sinker)
    6. 1 holding down bar with holding down sinkers (1 in leads, 1 in-1 out)
  10. Yarn let-off system
    1. Pos. 1 – 3; eba, mechanical let-off system with electronic control of linear let-off speed with let-off stop device
  11. Magazine weft insertion system (ems)
    1. Computer controlled horizontal weft insertion system 30 threads in pitch 1/3 in
  12. Shogging rake system (ers)
    1. Computer controlled shogging rake system for parallel weft insertion; direction of rake can be set according to threading
  13. Weft thread cutting device / vacuum unit
    1. Thermal cutting device to cut off weft thread ends for weft yarn (elastomeric)
    2. 2 vacuum units, separately arranged, without signalization
  14. Weft thread inspection
    1. Electronic weft thread inspection lasertop 4080 with yarn inspection lasertop 4080 for L1 + L2
  15. Antistatic device
    1. 2 x underneath weft insertion area over the whole working width
  16. Creel for elastomeric threads (ewc)
    1. For 10 cones, positively driven by servo motor; yarn tension via change gear adjustable from – to 200%
    2. Rolling yarn deflections
