    Abstract: A method for making sheets and/or plates that are thermoformable as of a temperature of 80-90° C. and heat-tackifiable as of 80-90° C., and suitable for use as a heat-tackifiable reinforcing material. According to the method, 30-70 wt % of granules of one or more polymers that have a low melting point (50-90° C.) and are thermoformable as of 80-90° C. are mixed with 70-30 wt % of one or more polymers with a higher melting or softening point, in the form of granules or a powder having a particle size greater than around 500 &mgr;m, and preferably of 500-1000 &mgr;m, both kinds of polymers being thermoplastic and at least partially compatible, and optionally with the usual additives; the mixture is extruded under low-shear conditions at low temperatures of 100-140° C. to give a mixture having a pasty consistency that is insufficient to form a uniform mixture of molten polymers; and, after extrusion, and optionally once a fabric base (9,12) has been added to the extruded product, the product is laminated or calendered at a high pressure and at a temperature of around 100° C. to reduce the thickness thereof, then cooled to less than 30° C. before the end of the lamination or calendering process.

    Abstract: The invention relates to a method for coating fibers shaped as fiber strands (roving and mats) using a fluidized bed techniques, wherein (i) the desired composition of the individual coating constituents is directly applied from the fluidized bed without previous compounding and (ii) the individual coating constituents contained in the fluidized bed are additionally mixed in the mass so that dissociation of individual constituents is substantially avoided. The invention also relates to a device for implementing the method.
