Title:
DEVICE FOR MANUFACTURING FILM AND METHOD OF MANUFACTURING DOUBLE-SIDED LAMINATED FILM
Document Type and Number:
WIPO Patent Application WO/2019/187394
Kind Code:
A1
Abstract:
This device for manufacturing a film manufactures a long double-sided laminated film. The device for manufacturing a film includes: a laminating unit which produces a single-sided laminated film by laminating a first layer on one side in a thickness direction of a long base film and produces a double-sided laminated film by laminating a second layer on another side in the thickness direction of the single-sided laminated film; a delivery unit that delivers the single-sided laminated film and the double-sided laminated film in a delivery direction; a marking unit that marks the single-sided laminated film; a measuring unit that measures the physical properties of the laminated film and the double-sided laminated film; a detection unit which is disposed upstream of the measuring unit in the delivery direction and detects the mark; and a calculation unit that determines the physical properties of the first layer and the second layer on the basis of the physical properties of the single-sided laminated film at a first position and the physical properties of the double-sided laminated film at a second position. The calculation unit determines the second position as substantially the same position as the first position in the thickness direction on the basis of the mark.
