In the rewind mode, the winder
runs until the dancer bar is brought to its highest position
whereupon the
motor stops running. When the process delivers paper to the
CI-750, the dancer drops, the motor runs, paper’s wound
and all’s well with the world.
In pay-off mode, the dancer dwells in the lowest position
when the downstream process is stopped. When the process
begins to draw paper, the dancer rises, and the motor begins
to turn. Paper feed is automatically synchronized to the
process.
In either take-up or pay-off mode, the amount of tension
on the paper is proportional to the position of the adjustable
weight on the dancer. Once the tension increases or decreases
causing movement of the dancer, the winding spindle changes
speeds accordingly. Hence, if the line speeds are modest
so that inertial effects can be ignored, the tension on
the paper rewound or dispensed is consistent regardless
of roll diameter.
The CI-750 may be built for either left-to-right or right-to-left
delivery. The shell is powder coated machinery gray. 12
or 18 inch tall mounting posts are available as optional
equipment.
