PROCESS AND APPARATUS FOR PRODUCTION OF TOILET PAPER ROLLS HAVING NO CORE

摘要

Rolls of toilet paper are produced by winding a paper web around each of a plurality of air permeable cylindrical cores each having a fixed, outer diameter while applying a liquid to only a leading portion of each web so that wound webs each having a wet inner portion are formed. After drying the wound webs to integrally bind the inner portion, the core is separated from each of the wound webs. T he above method is carried out using an apparatus including a winding device having a shaft to which the cylindrical cores are detachably fitted in a row, a drive device for rotating the cores supported by the shaft and to wind a paper web around eac h of the cores, an applying device for wetting only a leading portion of each to form a wet inner portion, a releasing device for releasing the wound web-bearing cores from the shaft to obtain arrays of the released, wound web-bearing cores, a drying device for drying the wet inner portion of each wound web, and a separating device for separating the wound webs from the cores. In one embodiment a fusible powder adhesive is applied to only a leading portion of the web.
