Abstract (en)
In a method of making a carton tube (8) by winding a carton strip (3) with a layer of glue (not shown) onto a mandrel (7), the new feature is that the carton strip (3) has previously been coated with a layer of glue of a kind, that can be changed from an inactive into an active state and vice versa, the glue being in the inactive state until passing through an activating unit (5) situated close to the winding-on point (9) (or even at these points or downstream of it, if thermal activation is used). By proceeding in this manner, spillage of glue on the equipment used for carrying out the method is avoided, thus reducing the need for supervision. <IMAGE>
