Abstract:
1. A method for producing a plastic product with integrated reinforcing structure, comprising the steps of: providing a clamping unit having at least three half-molds, two platens and an intermediate and reversing plate arranged between the two platens and rotatable about an axis; securing a flexible fabric element of fibers or filaments upon a mold surface of a half-mold of two half-molds of a first mold in a working area between a first one of the platens and the intermediate and reversing plate; closing the first mold to define a first cavity; introducing a first plastic material into the first cavity in the same working area between the first platen and the intermediate and reversing plate to form a first layer only on one side of the fabric element and curing the first layer at least in part; opening the first mold after the first layer has at least cured in part only on the one side of the fabric element, with the fabric element staying on one of the half-molds of the first mold; positioning a third half-mold in opposition to the one half-mold with adhering fabric element to define a second mold; closing the second mold to define a second cavity which opposes the first layer; introducing a further plastic material into the second cavity in the same working area between the first platen and the intermediate and reversing plate to form a second layer only on another side of the flexible fabric element and curing the second layer at least in part; opening the second mold after the second layer has at least cured in part only on the other side of the fabric element.
