​

Pile length at draw off:0.6875 to 1.375

17.5 mm to 35 mm

​

Tuft length

Kardax rug weave Loom speed:100 picks per minute Noise levels:not to exceed 85 dB Efficiency coefficient:(see below)

​

Weaving efficiencies ( hour to hour ) between 70 % and 80 % This figure will depend on the following variables:

•Correct tubing and creeling sequence

•Proper pile yarn quality

•Proper weft and warp yarn quality

•Knotless yarns

•Tuner / weaver / creeler skill and aptitude

•Proper utility services to loom and Jacquard

​

Production efficiencies ( month to month ): up to 80 % of weaving efficiency figure

This figure will depend on the following variables:

•Actual weaving efficiencies achieved

•Frequency and duration of creel changing

•Frequency and duration of pattern changing

•Frequency and duration of warp beam changing

•Time spent for maintenance / cleaning and other downtime

​

SHORT DESCRIPTION (FEATURES):

​

1. Total weaving machine, Jacquard and back half approximates to 25 tonnes total weight. Loom and Jacquard supplied as built-up integral unit.

Front view (right + left side)

​

2. Weft insertion by centre exchange rapiers, according to tip transfer technique, driven by conjugate cams in sealed gearboxes, through semi-flexible tape drive.

​

3. Many cam driven motions on loom and Jacquard use hardened and ground steel cams, operating in oil-filled, enclosed camboxes.

​

4. Weft Feeder by IRO.

​

5. Lay motion by conjugated cam drive, in fully enclosed oil-filled gearboxes, with 5 drives for 4 meter loom. Lay drives are incorporated in to the loom framing.

​

6. Warp shedding of the 3 heddle frames by 2 cams only.

​

7. Positively driven Gripper open and close motion, with controlled speed draw off to facilitate accuracy of tuft length and control of pile.

​

7. Knife drive and cutting by conjugated cam drive utilizing reduced size knife rail and knife carrier, and simple clamp-in type knife bit .

​

8. Loom back half supplied with standard warp beam stand warp beams included. Warp let off by individually controlled motorized drive units.

​

9. Carpet take up by servo-driven spiked roller.

​

10. Tuft rake driven from enclosed cambox drives

​

11. Fully flexible operational Electronic Jacquard, providing full 12 colour availability and operation, with provision for empty carpet backing frame.

​

12. On-loom control system features specifically designed MMI (Man Machine Interface), providing reporting on and adjustment to various loom settings and performance criteria.

​

14. Loom back half has been designed to accommodate a full 6 bar Grob warp dropper stop motion, integrated into the loom MMI.

​

15. Lubrication systems include for both centralized pumped lubricant controlled by loom

PLC, and fully enclosed oil-filled gear and camboxes.

​

16. Floor mounted, independently-driven carpet roll up unit.

​

17. The total number of warp beams supplied will be 9 (6 for use + 3 spares)

​

18. The yarn tube collector board, with supporting structure for mounting to the loom, clips, tubes and eyelets are included.

​

19. Whole creel construction is included
