Title:
FOIL SUPPLY DEVICE AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3784996
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a foil supply device and a method therefor capable of giving substantially fixed tensile force for a foil material at a previous step of a pull-out means.
SOLUTION: This foil material supply device consists of a supply roll 1, pull-out means 67a, 67b, a consumption amount sensor 81 which controls the drive of the supply roll 1 in accordance with a consumption amount of a foil material and is provided between the supply roll 1 and the pull-out means 67a, 67b, a deflection roller 19, a sensor roller 21, and a sensor means. The sensor roller 21 is supported and arranged in such a way that a distance from the deflection roller 19 is changed in accordance with a difference between a supply function and a pull-out function of the foil material 15. The sensor means senses changes of the distance from the deflection roller 19 of the sensor roller 21, accelerates the supply roll 1 when the distance from the deflection roller 19 of the sensor roller 21 is smaller than a first predetermined distance, and decelerates the supply roller 19 when the distance from the deflection roller 19 of the sensor roller 21 exceeds a second predetermined distance.
