Title:
SYSTEM FOR WINDING ROLL OF THERMOPLASTIC MATERIAL INTERLEAVED WITH POROUS MATERIAL AND ASSOCIATED METHOD
Document Type and Number:
Japanese Patent JP2018058704
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To align edges of a second material.SOLUTION: A device (un-interleaver) for unwinding a roll of a material interleaved with another material and separating the material, includes a first platform, a second platform, a tension sensor, an edge sensor, and a controller. The controller monitors a signal generated in a tension sensor and an edge sensor, and in response to the signal, the controller a) changes a speed at which the second platform is rotated to maintain a predetermined tension of a second material when the second material moves from the first platform to the second platform, and b) moves the second platform relatively to the first platform, and aligns an edge of the second material moving in a direction of a roll of the second material to an edge of the second material in the roll.SELECTED DRAWING: Figure 2
