| 摘要 |
<p>The present invention relates to a method for forming imitation branches (1), wherein a polymer mass comprising an expandable plastic is melted under pressure to form a first mixture, is then driven through an extrusion head (2) and is drawn from this extrusion head (2) in the form of an elongate plastic strand (3), wherein the method further comprises the following steps: - the mixing of at least a quantity of particles comprising vegetable fibres with at least a quantity of polymer to form a second mixture; - the co-extrusion of the formed second mixture with the first mixture so that the polymer at least partially encloses the said particles; whereby, on the basis of the formed second mixture, a first layer (4) is formed on the plastic strand (3), which first layer shall at least partially cover the outer surface of this plastic strand (3).</p> |
