Title: Extrusion of sheathing using shallow die gaps - to produce non-oriented coating free from potential retraction
IPC: B29C48/09
Filed: 1976-04-06
Abstract: Extrusion die for applying thin wall sheathing to a continuous substrate, where the die lip gap is less than the final thickness of the sheath, pref. by 5-35%. Used esp. for applying cable sheathing or for coating strip profiles with thermoplastic or elastomeric materials, esp. materials which may be crosslinked by treatment with moisture due to the presence of e.g., silane derivs. on a polyethylene. Extruded coatings having a thickness (a+x) after recovery from the initial die swell (a+x+y) which is greater than the original extrudate thickness (a) are alsmot free from molecular orientation. Insulation sheathing so made is not prone to subsequent longitudinal contaction which could expose core conductors or terminals, even if the coating is applied at high throughput rates.
