A glass tube forming device adapted to be used in a forming machine of glass containers for medical use includes a parallelepiped base block supporting a pair of arms each bearing a flat roller or idle deforming disc. The arms are L-shaped and are arranged in the upper part of the base block, and can be moved closer to, and farther away from, each other to be arranged to respectively engage on and disengage from a glass tube to be shaped. The deforming disc hangs from the free end of each arm and placed idle underneath the respective arm. Each arm has channels for oil and ducts for cooling air therein, ending at and above each deforming disc.

A device for manufacturing hollow glass articles, namely an IS machine, is characterized by a plurality of adjacent stations (3), which form a row and respectively accommodate at least one blank mold that encloses a mold cavity, the inner walls of which have to be coated with a lubricant in accordance with a defined spray pattern by means of a spraying device (8) that can be moved along the row during the course of the glass forming operation. In order to ensure a reproducible spray pattern, a calibration station (10) is provided and equipped with a test mold (12), wherein the spraying device (8) can be displaced up to an inspection position, in which it is arranged opposite of the calibration station (10), in order to verify the correct function of a lubrication process based on a spray pattern in the test mold (12) and, if necessary, to correct the lubrication process.

A device for manufacturing hollow glass article consists of a plurality of modular stations that, among other things, comprise blank molds and finish molds, wherein a housing (6) is provided and can be displaced along a blank mold side (3) in order to carry out at least control and servicing functions, and wherein said housing is formed by a key-like structure that is open in the direction of the blank mold side (3) and serves as a carrier for at least one manipulation element (7) consisting of multiple sections. On its free end, this manipulation element carries a tool or a device that is ready for use after it has reached the respective station. The shielding effect of the housing (6) reliably protects an operator side against accidents due to inadvertent interventions in machine motion sequences.

The invention relates to a closing mechanism for the mold halves (5) of an I.S. machine, consisting of two yoke-like mold holders (3, 4) which are mounted on parallel guides (1, 2) and can be moved along said guides between a closed position and an open position by means of a drive. A spindle transmission (13) is provided laterally to the guide (1) so as to extend parallel to said guide, consisting of a threaded spindle that is connected to the drive via a transmission (15) and is in engagement with two threaded sleeves, each of which is connected to one of the two mold holders (3, 4), via two threaded sections running in opposite directions for the purpose of producing an opening or closing movement of the mold holders (3, 4). By means of the drive, a servomotor, the opening and closing movement of the mold holders (3, 4) is carried out. Two pneumatically actuated piston-cylinder units (22) are provided in order to apply the clamping force required between the mold holders (3, 4) or the mold halves (5) in the closed position, said units likewise being connected to the mold holders (3, 4) via an interposed toggle lever mechanism. A more structurally simple and reliable design is provided for the closing mechanism, said design also being free of thermal stresses on the basis of a coolant network integrated at least into the mold holders (3, 4).
