METHOD OF MAKING CARTON TUBES, APPARATUS FOR MAKING CARTON TUBES BY CARRYING OUT THE METHOD, AND TUBULAR BODY MADE BY CARRYING OUT THE METHOD

摘要

In a method of making a carton tube (8) by winding a carton strip (3) with a layer of adhesive (not shown) onto a mandrel (7), a supply of wide sheet carton material (10) is coated with exception of its peripheral areas (11) with an activatable adhesive, said wide sheet is divided into strips that are fed to the mandrel (7) whereby the adhesive is activated just before the strip (3) reaches the mandrel. By proceeding in this manner, a spillage of adhesive is avoided throughout the production process.
