METHOD AND DEVICE FOR THE PRODUCTION OF A PLASTIC PROFILE

Straight plastic profiles from a plastics material and a continuous reinforcement are predominantly produced continuously in a strand, usually by the pultrusion method. As the plastic profile is pulled through a mold, only straight plastic profiles are formed in known pultrusion methods. In the production of plastic profiles using semi-finished products or complex fibrous constructions, congestion of the fibrous constructions or of the semi-finished products, and thus solidification of the material, may arise when entering the mold, such that the process has to be stopped. A method and a device for the simple production of individually molded plastic profiles is provided in that the mold is formed from at least two mold parts that in relation to the cross section of the plastic profile are split and are moved in a temporally offset manner counter to a production direction of the plastic profile along a portion of the plastic profile.
