Starred rolls

1. Starring is usually caused by greater tension on the outside edges of the roll than at the center.

2. Starred rolls can be prevented by applying higher riding roll pressure and torque differential at the beginning and then gradually reducing them to preset values before the roll diameter reaches 2/3m.

3. Starring puts a permanent kink in the paper that rarely comes out making it unsuitable for most uses.

— if only one end is starred, removing the soft, starred end can salvage much of the roll.
