Abstract

A process for the manufacture of sheets of spongy plastic material, characterized in that it comprises the extrusion of a hollow tube of spongy thermoplastic material, with the simultaneous inflation of this hollow tube, immediately applying a coating film to the spongy hollow tube, in a continuous manner, with the extrusion of the spongy material, by passing said coating sheet and the inflated hollow tube while said tube is under said inflation conditions, through a pair of rollers, the surface of the hollow inflated tube being facing the sheet of coating, at a temperature above the softening point of the thermoplastic sponge material and simultaneously during the passage of said coating sheet and said inflated hollow tube through said rollers, cause the joint thermal fusion of the contact surface of said cover sheet and said hollow tube menc this is done by firmly pressing the lining sheet and the hollow sponge tube together to the point that the spongy tube is compressed by more than 75% of the thickness it has before it is pressed.
