Main Structures and Technical Parameters:
1. Reed width:
Nominal reed width: 190, 230, 250, 280, 320, 340, 360 (cm);
Effective reed width: minus 0~60cm (190~250cm), minus 0~80cm (280~360cm).
2. Weaving scope: staple: 100~5s filament: 50~900D
3. Weft selecting: double-jet and four-jet (optional).
4. Main drive: super-torque motor; the loom stops by electromagnetic brake positioning;
power of main motor: 2.7KW (190-230cm), 3.0KW (250-280cm), 3.7KW (320-360cm).
5. Loom speed: 500-800rpm
6. Weft insertion: with parallel type of auxiliary main nozzle, main nozzle, auxiliary nozzle and stretch nozzle
controlled by electromagnetic valve, the computer uses irregularly shaped reed to control airflow
and weft yarn.
7. Shedding: negative cam shedding (eight heald frames at most), positive cam shedding (eight heald
frames at most),and dobby shedding (sixteen heald frames at most).
8. Take-up: Electronic take-up.Max. cloth rolling diameter: 600mm.scope of weft density: 25-300 picks/inch.
It has functions of electronic length-counting and stopping at fixed length.
9. Beating-up: beating-up mechanism with crank-type multi-slay sword; the crank is lubricated with oil bath.
10. Length measuring and weft storing: electronic control drum weft storing.
11. Weft stand: floor 2 and 4 cylinders.
12. Selvedge: planetary gear selvedge and independent electronic selvedge (optional).
13. Auxiliary edge: multi-cylinder type; parallel-cylinder type.
14. Weft cutting: mechanical cutter and independent electronic cutter (optional).
15. Lubricating system: closed oil-bath form for main driving parts; handle centralized lubrication for the
others.
16. Auto-stop device:
Weft yarn breakage: controlled by 2 photoelectric bobbin feelers;
Warp yarn breakage: controlled by electric 6-line droppers;
Others: broken ends of leno selvedge yarns and auxiliary selvedge yarns are controlled by different
electronic switches;
Display of the cause of loom stopping: messages are displayed on the display screen; multi-functional
4-color lamp stopping display.
17. Automatization: multi-functional computer control system (functions of condition setting, controlling,
monitoring and auto diagnosing etc.); automatic cloth-fell fitting: slow dot motion by converter (positive
and negative rotation); function of memory card.
18. Weight: 3.5~4.8T
19. Site area: positive shedding: (4330~6030) ×1860 (mm).
