A star construction having variable pitch arms for a rotary molding machine for making plastic vessels and bottles, comprises a plurality of arms including gripper elements and a system including two levers which engages with the grippers, while cooperating with respective cam contours, the lever and cam system being reciprocatedly driven for providing a pitch variation and controlling the positions of the gripper elements. With respect to prior solutions, the variable pitch arm star construction according to the invention allows to quickly and simple perform the operations necessary for modifying the arm pitch.
Dispositif en étoile comportant des bras à pas variable pour moule à carrousel destiné à la fabrication de récipients et de bouteilles en plastique. Le dispositif présente de multiples bras comprenant des éléments préhenseurs et un système composé de deux leviers s'engageant dans ces éléments et travaillant de concert avec les cames correspondantes. Le système leviers-cames se déplace dans les deux directions afin de permettre la variation du pas et le réglage de la position des éléments préhenseurs. La construction en étoile permet un changement simple et rapide du pas des bras.
