Apparatus for winding lightweight web

摘要

The apparatus serves for forming reels of lightweight paper intended for paper processing plant (rolls of toilet paper, paper towels and the like and for other products, such as nonwovens) where control of the density of the reel is critical. The tubular core or mandrel on which the paper is to be wound is held by driven mating centres 14 mounted on blocks 12 that travel up and down generally vertical guides 9; driven threaded columns 18 slowly raise the blocks 12 as a function of the instantaneous diameter of the developing reel. The load of the reel on the underlying rolls 3 is thus limited.
