Disclosed is a device (10) for producing cross-finned pipes, which exhibits molding cheek halves (12) lying adjacent to each other along a common molding segment and forming a molding channel (18) in-between the latter. A stationary linear guiding device (42) is provided along the molding segment in order to guide the molding cheek halves (12). Said device exhibits an elongated central sliding body (44), preferably made of a sliding metal alloy, and two guiding oil-lubricated bodies (46) placed laterally adjacent to the sliding body (44), said bodies being made preferably of an abrasion-resistant metal.
L'invention concerne un dispositif (10) pour produire des tubes à nervures transversales, lequel comporte des demi-mâchoires (12) qui sont adjacentes le long d'une section de moulage commune et qui forment un canal de moulage (18) intermédiaire. Un système de guidage linéaire fixe (42) est disposé le long de la section de moulage afin de guider les demi-mâchoires (12). Ce système comprend un élément coulissant central allongé (44), constitué de préférence d'un alliage de métaux antifriction, et deux éléments de guidage (46) lubrifiés à l'huile et placés latéralement au voisinage de l'élément coulissant (44), ces éléments étant constitués de préférence d'un métal résistant à l'abrasion.
