MANUFACTURING DEVICE AND PREPARATION METHOD FOR CIGARETTE PAPER HAVING FLAME-RETARDING STRIPES

摘要

A manufacturing device and preparation method for cigarette paper having flame-retarding stripes. The device comprises a first coating press roll and a second coating press roll, the first coating press roll and the second coating press roll being in contact with and parallel to each other and having opposite axial rotary directions. The cigarette paper passes through at the position where the first coating press roll and the second coating press roll come into contact. A feeding tube is provided at the outside of the first coating press roll and/or the second coating press roll. The feeding tube is provided with multiple feeding nozzles. The method comprises first applying on the surface of the raw paper of the cigarette paper a coating of diffusion-resistant, permeation-resistant coating material such as oxidized starch or sodium carboxymethyl cellulose so as to reduce wrinkles during flame-retarding stripe printing, and then printing flame retardant on one or both sides thereon.
