Method and an apparatus for producing exam table paper rolls
Abstract:
A method relates to the production of paper rolls for examination tables, obtained from a tape (100) of embossed paper, having two layers (10, 20), joined together. The band (100) is obtained in known way from two continuous webs (1, 2), subjected to subsequent steps of embossing, glue (C) application, coupling and stabilization. The method includes applying measured quantities of a sanitizing and/or disinfectant substance (S) between the two layers of embossed paper (10, 20) before their joining; preferably, the substance (S) is applied to the same continuous web (1) that is aimed at receiving the glue (C), after the embossing step and contemporarily with the glue (C) application, by spot-application of a mixture (M) in aqueous solution containing suitable percentage of the glue (C) and sanitizing substance (S) to the tops (11A) of the embossing relieves (11.) In this case, the application means (240) for sanitizing substance (S) are formed by the same means (220) for applying the glue (C).
