Description of problem:
“Long” on the tooth edge is a term used to describe the straightness of the band. The teeth are on the outside of the arc when the strip is lying on a flat surface.
Likely causes:
- Side guides are too tight – causing rubbing near gullets.
- Excessive “preload” – causing the band to ride heavily against the back-up guides.
- Worn band wheels causing uneven tension.
- Excessive feed rate.
- Guide arms are spread to maximum.
- Improper band tracking – back edge rubbing heavily on wheel flange.
