Patent number: 6372294Abstract: The method for the manufacture of unidirectionally fiber reinforced thermoplastic bands comprises a pressure impregnation of a fiber strand in a bath with a dispersion of thermoplastic particles. Heat treatments for the drying of the strand and a melting on of the particles taken up by the strand follow the pressure impregnation. The strand is drawn through the bath at a predetermined draw-off speed about a plurality of deflection elements. The dispersion of the bath is largely held in a stationary state, namely through the supply of an infeed dispersion with a first particle concentration and through an initial setting of a second particle concentration in the bath: The infeed dispersion is fed in continuously or periodically, with the first particle concentration being held constant. A corresponding feeding in of a dispersion of higher particle concentrations as well as an additional amount of dispersing medium is possible.Type: GrantFiled: February 19, 1999Date of Patent: April 16, 2002Assignee: Sulzer Innotec AGInventors: Albert Maria Vodermayer, Jens Kärger, Stefan Kaufmann, Hans Erlach
