Main take-down
A motor drives the take-down roller (1). The motor can individually be
adapted to the knitting situation. The take-down roller guides the finished
fabric into the fabric collection chamber. There the fabric is protected from
soiling.
Take-down tension The take-down tension consists of:

Pre-tensioning when the carriage assembly is at the reversing point

Take-down tension during knitting
Both tensions are independently set of each other. The optimum value for
the take-down tension is dependent on the working width, yarn material and
pattern.
The fabric is pressed onto the take-down roller (1) with counter-pressure
rollers (2). The contact pressure can individually be adjusted with knurled
screws (3). The counter-pressure rollers (2) can be continuously swiveled
with the key (4). Press the key (4) to open or close the counter-pressure
rollers with the motor.
Premature wear of the take-
down roller
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

Yarns harmful to rubber, e.g. abrasive, sanding yarns or yarn finishes
such as greases or oils

UV radiation

Cleaning agents harmful to rubber, e. g. ether or fuels.
Recommendation: Use cleaning petrol for cleaning
