Title:
LAMINATOR FOR CORRUGATED CARDBOARD SHEET
Document Type and Number:
Japanese Patent JP3243513
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To correctly and effectively overlap by cutting a single faced web in accordance with a cover sheet so that the cover sheet which is printed in advance and supplied continuously and intermittently and the single faced web pass through a laminating nip and are bonded.
SOLUTION: In a state in which a single faced web 12 coated with a contact agent by a glue applicator 18 is moving, a sheet 10 is sent by a sheet feeder 14 synchronously with a downstream side vacuum conveyer 17 through upstream side vacuum, and guide conveyer 15, 16 at appropriate speed and intervals for the length of the sheet. When the front margin of the sheet reaches a branch photo-eye 46, it is decelerated and stopped at a prescribed position upstream from a positioning nip 33. The end of the sheet 10 is conformed to the approaching single faced web 12 by a laminating nip 11, and the single faced web 12 is cut into the sheet length by a cutting knife 20. The moving web is removed from a system by a diverter 45. A sheet feed system is reopened by a front margin photo-eye 35.
