Abstract
Official abstract text for this publication.
An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension-sensor and the edge-sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, the apparatus comprising: a first platform configured to: hold a roll of first material interleaved with a second material such that a longitudinal axis of the roll is vertical or substantially vertical, and rotate to unwind the first and second materials from the roll; a second platform configured to: hold a roll of the s…
