<p>The roller stacks (2, 12) include intermediate rollers (6, 16) in circumferential contact with further rollers (4, 5, 14, 15). These are located to the sides of the stack plane (S). They are displaceable, being mounted in a forked arrangement on either side of the intermediate rollers. Rollers forking on either side of the stack can be displaced selectively around the circumference of the intermediate roller they embrace. There two rollers in symmetrical, or asymmetric and flexurally-adjustable. The fork mounting is double ended. The stack is forked to a central intermediate roller. Two rollers of the stack are soft, with alternating gaps between them. Forked rollers adjust circumferentially through 30[deg] to 60[deg] with respect to the stack plane. Stack rollers are power driven with individually-adjustable torque. They are connected to a control circuit varying nip stretch loading, drive power and roller speed.</p> |
