Abstract
A tool for impregnating a reinforcing fiber material with plastic comprising a support element supporting face facing and spaced from a cover element covering face. A receiving space, between the supporting and covering faces, is connected to an injection channel for supplying the plastic into the space and comprises an inlet opening for continuously feeding the fiber material into the space, as well as an outlet opening for continuously removing plastic impregnated fiber material. The distance between the supporting and covering faces is constant, perpendicular to a feed direction of the fiber material and parallel to a plane defined by at least one of the supporting and covering faces. The support and cover elements are movable relative to one another such that the distance between the supporting and covering faces in the feed direction is adaptable to a varying thickness of the fiber material fed through the receiving space.
