Abstract
L'invention concerne un appareil d'extrusion à cylindres. Ledit appareil comporte une paire de cylindres qui sont montés de façon à tourner et à céder obliquement sur un bâti placé à l'extrémité de sortie d'une boudineuse. Les cylindres sont retenus par une force dans le bâti de manière à leur permettre de se déplacer obliquement par rapport au sens d'écoulement de la matière extrudée, ce déplacement non perpendiculaire des cylindres facilitant leur réglage et leur nettoyage Application à l'extrusion de matières plastiques par des boudineuses à vis.The invention relates to a roll extrusion apparatus. Said apparatus comprises a pair of cylinders which are mounted so as to rotate and yield obliquely on a frame placed at the outlet end of an extruder. The cylinders are retained by a force in the frame so as to allow them to move obliquely with respect to the direction of flow of the extruded material, this non-perpendicular movement of the cylinders facilitating their adjustment and cleaning Application to the extrusion of materials plastics by screw extruders.
