ABSTRACT:
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. The 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 each 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.
