Abstract: A molding device for manufacturing thermoplastic containers by blow-molding or stretch-blow-molding heated parisons. The molding device having a blow-molding mold of the hinged mold type with at least two mold halves which can be separated from one another by rotation about a common axle of articulation under the action of an actuating device. The actuating device is designed in such a way that the two mold halves have respective angles of opening on each side of the parting plane of the mold which are not equal.

Abstract: Device for conveying objects, includes a rotating support having a transfer arm which consists of a plate and a gripper head which can bear at least one object and which is slidingly mounted in relation to the plate according to a direction. The gripper head (20) is coupled to a slider sliding in a slide rail fixed to the plate, and including a first and second cam system in order to respectively slidingly drive the gripper head and to pivotingly drive the plate, according to the angular position of the arm around the axis of rotation of the support. The slider is constructed as a single part which has an overall rail shape, and the profile of the slider is complementary with respect to the profile of the slide rail. The gripper head is fixed such that it overhangs on the distal end section of the slider.

Abstract: A rotary machine for producing recipients made of a thermoplastic material by drawing and blowing performs by a molding device which is provided with an openable mold and a movable drawing rod, a device for supporting and driving the drawing rod, which is embodied in such a way that it is mechanical and includes a power take-off device for generating, on the basis of a monodirectional rotary rotation, two rotary motions of given angular amplitudes of a rocker in two predetermined angular places of a merry-go-round path and a device for converting the two rotary movements of the rocker into two opposite linear alternately descending and ascending displacements of a drive unit connected to the drawing rod.

Abstract: A method of controlling the opening and closing of a book-type blow mold that is used to produce containers from a thermoplastic material, such as PET, by blowing or blow-drawing heated preforms. The mold includes at least two mold halves which can be moved away from one another by rotating the same around a shared fixed pivot pin. The two mold halves are opened asymmetrically on either side of the parting plane thereof and, as a result, the mold half that is open the most forms a larger passage for introducing an auxiliary member, such as a clamp arm, into the mold.
