ROLL OF ELONGATED MATERIAL, METHOD FOR THE PRODUCTION THEREOF AND MEANS FOR CARRYING OUT THE METHOD

摘要

The invention relates to a roll of elongated material, for example soft paper. The roll is rolled on a core at the centre of the roll, which core consists of a number of turns of the material and are fixed in relation to each other. The invention is characterized in that the roll is present in a compressed elliptical or oval form and that the core is elastic in such a way that it can be opened from the compressed state by pressure against the shorter sides of the ellipse. The invention also relates to a method for the production of a roll and a means for performing the method, which means is characterized in that two converging synchronically driven conveyor bands at one end of the winding shaft compress the roll immediately after the winding.
