Abstract
The present invention relates to a method for producing a textile product of the lapped/bonded type from fibres and/or filaments travelling in the direction of advance in the form of a web, this method comprising at least one step, called the “prelooping step”, in which the fibres and/or filaments individually undergo looping transversely to the direction of advance of the web, if appropriate accompanied by transverse drawing, characterized in that it subsequently comprises a step of confining the parallelized fibres and/or filaments in the form of loops, this latter confining step taking place directly on a support, without transport members, such as needles or transfer elements, being involved.

Method for producing a textile product of the lapped/bonded type from fibres and/or filaments travelling in the direction of advance in the form of a web, this method comprising at least one step, called the “prelooping step”, in which the fibres and/or filaments individually undergo looping transversely to the direction of advance of the web, if appropriate accompanied by transverse drawing, characterized in that it subsequently comprises a step of confining the parallelized fibres and/or filaments in the form of loops, this latter confining step taking place directly on a support, without transport members, such as needles or transfer elements, being involved.
Method according to any one of the preceding claims, characterized in that the support is the substrate of the final product.
Method according to any one of the preceding claims, characterized in that the speed of advance of the support is uniform or takes place in bursts.
Method according to any one of the preceding claims, characterized in that a second substrate is deposited onto the product comprising the basic substrate and the fixed loops, in order to produce a sandwich product.
Apparatus for carrying out the method according to any one of the preceding claims, comprising a set of discs (11) which are carried on a common transverse shaft (13) and are driven in continuous rotation and which are provided, on their periphery, with a toothing (15) which has an angle relative to the tangent and arranged between which are looping fingers (21), the ends of which are presented essentially tangentially relative to the discs, characterized in that it possesses, furthermore, in the extension of each looping finger (21), a detaching foot (31).
