Abstract
A machine and a method produce strips from a fiber-reinforced plastics composite material. The machine includes a housing through which fibers pass and in which profiled bars are fixedly or rotatably mounted, which are oriented perpendicularly to the passing direction of the fibers and by which forces can be applied alternately to the top and bottom of the fibers and to their coating with a plastics material in order to impregnate the fibers and to consolidate the plastics material between the fibers. The ratio of the average total contact length of all the profiled bars used in the impregnation in millimeters to the number of profiled bars is between 2:1 and 1:400, preferably between 1 and 1:200 and particularly preferably between 1:10 and 1:100.
Claims16
A machine for producing strips from a fiber-reinforced plastics composite material, comprising a housing through which fibers pass and in which a plurality of profiled bars are fixedly or rotatably mounted, which are oriented perpendicularly to and/or vertically relative to the passing direction of the fibers and by means of which forces can be applied alternately to the top and bottom of the fibers and to their coating with a plastics material in order to impregnate the fibers and to consolidate the plastics material between the fibers, wherein the ratio of the average total contact length of all the profiled bars used in the impregnation in millimeters to the number of profiled bars is between 2:1 and 1:400, wherein the machine comprises at least 10 profiled bars.
