something (folded paper or
cloth) in the areas on the

looser. You will have to move
your paper every time you

shuttle to pass freely. However, because the shed on AVLs is so precisely
calibrated, you do need to be sure that you’re getting all that the loom can
deliver.

The advantage of an end-feed
