Scale |
- A motor drives the take-down rollers (1).
These provide the take-down tension and guide the finished fabric into the fabric collection chamber. - The contact pressure can individually be adjusted with knurled screws (2).
- The scale (3) simplifies the adjustment.
Take-down tension
The take-down tension consists of:
- Pretension at the carriage reversing point (WMI)
- Take-down tension during knitting (WM)
You can set both take down values independently of each other.
The optimum value for the take-down tension depends on:
- Working width
- Yarn
- Pattern
Premature wear of the take-down rollers
The roller rubber of the take-down roller (1) is prematurely worn by:
- Fabric take-down values too high (roller spins)
- Contact pressure too high
- abrasive, sanding yarns
- yarn finishes such as greases or oils
- UV radiation
- Cleaning agents harmful to rubber.
