摘要： The invention concerns a machine for making thermoplastic containers by stretching and blowing a preform (10), comprising several moulding stations (12) mounted on a rotary carrousel (14), each station (12) being provided with at least a stretch rod (20) whereof the sliding movement is controlled along an axis (An). The invention is characterised in that the stretch rod is controlled by a magnetic device comprising at least a fixed magnetic guide (36, 38, 40, 42) arranged about the axis (A1) of the carrousel (14) and a slide (24) which is integral with the stretch rod (20) and bears at least a magnetic shoe (32, 34) and the shoe and the guide co-operate by magnetic coupling such that the guide imposes a predetermined axial movement on the slide (24)

摘要： The invention concerns a method for blow moulding plastic hollow bodies which consists in: associating with each mould (7) a particular compression chamber (21), consisting of a cylinder (20)-piston (19) assembly; initialising the pressure in the chamber; compressing the fluid in the chamber; communicating (22, 24, 25) the chamber with the blank (9) when the position of the piston reaches a predetermined position and keeping on reducing the chamber volume to complete the blow moulding. The invention is particularly useful for blow moulding hollow bodies with a small volume.

摘要： The invention relates to a machine for blow-molding thermoplastic products. This type of machine has a molding unit comprising two mobile supports (12), which are hinged in relation to each other and which are controlled by a mechanism comprising a traveling slide (16), between an open position and a closed position. Each support (12) is connected to the slide (12) by at least one associated connecting link (36). The inventive blow-molding machine is characterized in that in its closed position, the main axes of the connecting links (36) are oriented in the same direction, perpendicular to the hinge axis (A1), in such a way that the control mechanism can cause the molding unit to be locked in this closed position.

摘要： Device (1) for supporting a preform in an endless chain for conveying preforms that rotate simultaneously about themselves. The device comprises a plate (2) hingedly coupled to two adjacent plates and supporting a rod (5) removably fastened to the open end of a preform (8). The plate includes a linking stem portion (11) supporting a dome-shaped surface forming a coupling head (12) for contacting the associated adjacent plate, and a spherical seat portion (13) with a central axial opening (14) for the free passage of the linking stem portion (11) of the associated adjacent plate. The device is characterized in that the dome-shaped surface forming a coupling head is mounted free to rotate on said linking stem portion. A contact plate (16) is fastened to the free end of the linking stem portion (11) and extends transversely thereto substantially parallel to the side of the coupling head (12) opposite the side of the spherical cap. An annular bearing (17) is placed coaxial to the linking stem portion between the sides mutually opposite the coupling head (12) and the contact plate (16).

摘要： The invention concerns a cam-operated guiding device for controlling a related movement of a member (9) which is moreover continuously displaced, the device comprising two mutually transversely offset parallel cams with which co-operate respectively two coaxial rollers (6, 7) for bilaterally guiding said member. The invention is characterized in that one of the cams (4) is mounted via elastically deformable means (10, 12) designed to allow an elastic displacement of said cam (4) relative to the other cam (5).
