Title:
プラスチック系有孔三次元構造体を製造するための方法およびこの方法を実施するための装置
Document Type and Number:
Japanese Patent JP2011511873
Kind Code:
A
Abstract:
Process for manufacturing a plastic-based perforated three-dimensional structure comprising: a step (1) during which a flat structure of a composition based on at least one thermoplastic polymer (P) chosen from amorphous and semi-crystalline polymers is continuously extruded; a step (2) during which the flat structure resulting from step (1) is fabricated in the form of a perforated three-dimensional structure; a step (3) during which the perforated three-dimensional structure is grasped using gripping means comprising two pairs of jaws that are applied to the two side ends of the structure on both sides of the latter, each pair having its jaws at a given distance from one another in order to apply a controlled compression ratio to the structure; and a step (4) during which the perforated three-dimensional structure is drawn by moving the two pairs of jaws relative to one another in a direction perpendicular to the extrusion direction and by keeping the distance between the jaws of one and the same pair constant.
