Abstract
Abstract By starting from a non-bound fibre fleece one manufactures a composition consisting of a fleece strengthened at the fibre junctions with a stiffening agent and a foil, by taking care to have a discontinuous pattern of said stiffening agent available at the moment of uniting said fleece with said foil; the discontinuous pattern is obtained with a cylindrical screen with internal squeegee.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A method for manufacturing a composite product of fibers laminated with a foil comprising the steps of forming a single layer of loose fibers as fleece in an unbound condition and devoid of binding agent upon a foil, applying a binding agent in a discontinuous pattern on the uncovered face of the fiber layer during or after the combining of the fibers and the foil by passing the same past a screen cylinder, the binding agent being caused to penetrate the fibers from the top of the layer of fleece to the foil to adhere fibers to the foil in said discontinuous pattern and to bind fibers to each other in an irregular pattern.
Claim 2
Independent Claim
114 words
A method for manufacturing a composite product of fibers laminated with a foil comprising the steps of forming a single layer of loose fibers as fleece in an unbound condition and devoid of binding agent upon a foil, applying a binding agent in a discontinuous pattern on the uncovered face of the fiber layer during or after the combining of the fibers and the foil by passing the same past a screen cylinder, the binding agent being caused to penetrate the fibers from the top of the layer of fleece to the foil to adhere fibers to the foil in said discontinuous pattern and to bind fibers to each other in an irregular pattern.
Claim 3
Dependent Claim
36 words
The method according to claim 1, in which a quantity of binding agent in a suitable pattern is applied to the fibre fleece that a part of the binding agent penetrates as far as the foil.
Claim 4
Dependent Claim
60 words
The method according to claim 1, in which the fleece is supplied at some pressure to a not yet dried, gelled or polymerised foil which is advanced on a temporary supporting belt, whereupon the binding agent pattern is applied to the uncovered face of the fleece and the entire aggregate is heated and/or dried and finally the belt is removed.
Claim 5
Dependent Claim
42 words
The method according to claim 1, in which the foil is passed past a screen cylinder in order to apply a suitable pattern of binding agent and that only thereupon the fibre fleece is supplied to the printed face of the foil.
Claim 6
Dependent Claim
36 words
The method according to claim 4, in which the adhering foil and fibre fleece are passed past a second screen cylinder in order to apply a binding agent pattern to the uncovered face of the fleece.
