Abstract
System for the continuous winding of laminar bands, of the type qeu contains heat-sealing materials, characterized in comprising the steps of grooving the laminar band partially and longitudinally; start rolling on itself along its longitudinal axis; complete the rolling until obtaining a tube with the two overlapping edges; and welding said edges to form a stable tubular element.
