I wove a 40 inch blanket on my AVL, I found the tension at the selvedges to become progressively loose as I wove causing the fabric to become "wavy". I checked the tension at the beam and it was consistent. The tension at the fell is not.
I noticed that the cloth apron for the auto advance is very loose at the outer edges, almost wavy? I Had recently washed the apron and wonder if this caused the apron to become saggy? Any input would be appreciated. I had this problem on a run of narrow towels but thought it was poor beaming. I am going to weave a blanket using the sticky beam and see if it is indeed the beaming, the issue appeared to get progressively worse after several inches of weaving. The sag was very noticeable at the outer edges of the apron. Any input appreciated?
