Twin-belt drawing unit - has a fixed guide for one belt and a moving adjustable guide for the other belt

摘要

The angle of the movable belt guide allows a stepless adjustment of the size of the gap between the continuous belts at the outlet for the fibre material being drawn out of the feed rollers. This gives a lateral and longitudinal stepless adjustment, in relation to the movement of the fibre material, in their vertical planes. The system ensures that the whole of the fibre material can be given a controlled processing at the outlet, and also that there is the best possible distribution of the friction force fields in the fibre material being treated.
