Abstract: front page image
(EN)An extrusion apparatus is used for extruding material through a nozzle (10) for forming a product In the nozzle (10), the material is pressed around rods (9) so that tubular cavities (13) are formed in the wall of the product. The rods (9) are hollow and the apparatus comprises channels (14) connected to the hollow rods (9) to enable flow in the tubular cavities (13).
(FR)La présente invention concerne un appareil d’extrusion servant à extruder un matériau par une buse (10) afin de former un produit. Dans la buse (10), le matériau est pressé autour de tiges (9) de manière à former des cavités tubulaires (13) dans la paroi du produit. Les tiges (9) sont creuses et l’appareil comprend des canaux (14) reliés aux tiges creuses (9) pour permettre un écoulement dans les cavités tubulaires (13).
