Title:
METHOD AND APPARATUS FOR MANUFACTURING RESIN FILM
Document Type and Number:
Japanese Patent JP3674194
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a manufacturing method and apparatus with high productivity being inexpensive and having almost no changing losses by providing a winder with an automatic changing mechanism for winding up connected resin films on a waiting resin film winding roll.
SOLUTION: Rolling out shafts 1a, 1b of a release sheet 4 having a turret mechanism have winders 4a, 4b with release sheets 4 wound respectively. Those are the winding out shaft 1a being in the period of winding out a release sheet currently and the winding out shaft 1b being in the period of winding out a waiting release sheet currently. The winding out shafts 1a, 1b include each pre-driving unit that commonly acts as a primary driving unit for conducting pre-driving before primary driving by sequence control. The press mechanism 2 operates to press and superimposed the release sheet 4 of the release sheet winder 4a being wound out currently on the waiting release sheet winder 4b and then to join the sheets through adherence. Finally, the release sheet 4 from the winder 4a being currently in winding out period by a cutting mechanism 3a is cut off the winding shaft.
