## Abstract

Disclosed is a sheet winder which enables a sheet roll paper wound in a roll shape to be used in manufacturing of a corrugated cardboard for packing cases, in which the sheet roll paper is obtained by laminating sheet papers printed one by one using a lithography technique as one of the most general and economical printing methods and a roll paper used as a material for manufacturing the corrugated cardboard for packing cases.

## Claims

### Claim 1

A sheet winder for winding a sheet as a material of a packing box, wherein:
sheet papers printed with characters and figures are supplied from a sheet paper supply part to a laminating part;
a roll paper supplied from a roll paper supply part is preheated by a first preheating roll and supplied to an adhesive coating part;
the roll paper coated with an adhesive by an adhesive coating roll in the adhesive coating part is preheated by a second preheating roller and supplied to the laminating part;
the sheet papers and the roll paper are laminated as a sheet roll paper while passing between a laminating roll and an auxiliary laminating roll in the laminating part;
the sheet roll paper is dried while passing through an infrared drying part in which infrared light is irradiated by an infrared lamp and a heating roll drying part in which heat is radiated by a heating roll;
the sheet roll paper is cooled while passing through a cooling part having a cooling fan, and wound in a winding part;
a cleaning roll transfers a cleaning solution of a cleaning solution container to the laminating roll so that the laminating roll is cleaned, and a scraper scrapes the cleaning solution on an outer circumferential surface of the laminating roll; and
a scraper cleaning roll transfers the cleaning solution stored in the cleaning solution container to the scraper so that the scraper is cleaned.
