Abstract
Process for the manufacture of a sheet of thermoplastic material, with piliform projections, on at least one of the two surfaces, using a molding plate with a plurality of conical depressions, characterized in that a sheet is placed on it, at least , of thermoplastic material, then applying heat and pressure to said sheet, in proportions sufficient to soften it and so that a part of one of the surfaces of this sheet is introduced, in the conical depressions, stopping the application of heat and pressure, and cooling then the sheet and plate under pressure, to prevent the piliform projections of the sheet from being broken and retained inside the conical depressions, and cooling and pressure then ceasing, to separate the sheet, already with the piliform projections molded.
