Joining an endless web to a continuously transported mat

Abstract

Abstract 1. Process of applying at least one endless band (4) under tension, in particular a band of lining, to a material in the form of a sheet (1) transported continuously over a track, which band is unwound against braking forces which are greater than the force of traction acting at the point where the endless band meets the material to which it is applied, according to which the endless band (4) is carried against a transporting surface (7) which permits the passage of air and behind which a vacuum is produced and which moves in the sense of transport of the endless band (4) at a velocity at least equal to the velocity of the sheet, characterised in that the application is achieved by putting into operation the following measures, either jointly or separately : - the vacuum is adjusted to a value which allows for sliding between the surface of transport (7) and the endless band (4) so that the velocity of the surface of transport (7) may be greater than the velocity of transport of the sheet of material (1), - the surface of transport (7) is urged elastically both against the sense of transport of the band (4) and against the pressure of said band.
