Abstract:
A method of producing a stabilized extensible necked material comprising the steps of:a) providing a neckable material; b) feeding the neckable material in a first direction; c) subjecting the neckable material to incremental stretching in a direction perpendicular to said first direction; d) applying a tensioning force to the neckable material to neck the material in a direction perpendicular to the first direction; e) subjecting the necked material to mechanical stabilization to provide a stabilized extensible necked material; f) passing said stabilized extensible necked material between a peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder; g) retarding the passage of stabilized extensible necked material by a retarding member; and h) directing the stabilized extensible necked material away from the peripheral surface of the cylinder.
