Claim:
1. A process for the production and the use in moulding of a fiber-based armature particularly adapted to be embedded in a matrix or a mixture of matrices, comprising the steps of: preparing a layer of fiber-based non-woven material having one exterior surface of fibers; depositing a repositionable hot melt glue in liquid form on said one exterior surface of fibers to form one adhesive exterior surface on the layer of fiber-based non-woven material, the hot melt glue having an almost instantaneous setup on the one exterior surface of the fibers; pressing a removable separator onto the one adhesive exterior surface so that the removable separator adheres to the one adhesive exterior surface; removing the pressed separator from the one adhesive exterior surface; cutting a piece from the layer of fiber-based non-woven material to conform to the configuration of a mould to enable positioning of the cut piece in the mould, said piece having one adhesive exterior surface; positioning the piece on a wall of the mould or on another piece of fiber-based non-woven material previously positioned in the mould such that the one adhesive exterior surface of the piece directly contacts either the wall of the mould or the another piece of fiber-based non-woven material; wherein removing the pressed separator from the one adhesive exterior surface is carried out after cutting the piece from the layer of fiber-based non-woven material to conform to the configuration of a mould to enable positioning of the cut piece in the mould; and wherein the repositionable glue provides the one adhesive exterior surface with a repositionable nature such that the piece can be adhered upon contact with either the wall of the mould or the another piece of fiber based non-woven material, positioned and subsequently partially or completely removed from the wall of the mould or of the another piece of fiber-based non-woven material and re-positioned during the positioning step without any degradation of the piece or of the already positioned fiber non-woven material.
