Abstract: In order to permit more effective cooling in comparison to the prior art, in particular in its floor area, of a hollow glass article (1) standing upright on the base (2) of a setting plate (4) provided with transcurrent orifices (9, 9?, 9?) forming a cavity (8) between a base (2) and the facing surface of the setting plate (4) of the standing surface (2?), it is proposed to utilize a part of the orifices (9) situated inside the standing surface (2?) for the supply of cooling air into the cavity (8), and to utilize the remaining orifices (9?) inside the standing surface (2?) only for the extraction of cooling air from the cavity (8).

Abstract: A process and a device for pushing hollow glass objects off a glass forming machine onto a moving conveyor belt are disclosed. Each hollow glass object is pushed by a push-off unit from a dead plate along a curved path onto the conveyor belt in such a way that the curved path is brought tangentially to a contact point in a movement direction of the conveyor belt. Subsequent to the contact point each hollow glass object is pushed further by the push-off unit by a further linear path portion in the movement direction of the conveyor belt as far as a release point at which the push-off unit is released from the hollow glass object. The push-off unit is then moved back to dead plate.

Abstract: A device for transferring an object from a dead plate of an Individual Section glass-forming machine to a conveyor belt is disclosed. The device includes a first shaft rotatable about an axis. A housing is attached to the first shaft. A carrying arm is slidably mounted on the housing and has a finger at one end for engaging the object. A guide piece having a groove is attached to the other end of the carrying arm. A crank arm engages the groove. The crank arm is connected to a second shaft coaxial with the first shaft. The shafts rotate independently of one another. Each shaft has its own drive unit. Rotation of the first shaft rotates the carrying arm about the first axis and rotation of the second shaft causes sliding motion of the carrying arm along its longitudinal axis.

Abstract: A for horizontally transferring at least one hollow glass object from a dead plate of each section of an I.S. (Individual Section) glass-forming machine to a conveyor belt which is common to all sections is characterised by a transfer device (30) which is connected via a carrying bar (42) to a guide piece (35) which can be displaced along two guide rods (36) which are disposed in a housing (13) in parallel with each other at a mutually spaced disposition and extending in a horizontal manner. A freely rotatable roller (32) which is disposed on one end of a crank (28) engages in a groove (34) of the guide piece which extends in a perpendicular manner with respect to the two guide rods (36), wherein the crank (28) can rotate about an axis (8) which extends in parallel with the axis of the roller (32).

Abstract: Each hollow glass object (7) is pushed by a push-off unit from a dead plate (1) along a curved path (10) onto the conveyor belt (5) in such a way that the curved path (10) is brought tangentially to a contact point (11) in a movement direction (6) of the conveyor belt (5). Subsequent to the contact point (11) each hollow glass object (7) is pushed further by the push-off unit by a further linear path portion (12) in the movement direction (6) of the conveyor belt (5) as far as a release point (13) in which the push-off unit is released from the hollow glass object (7). The push-off unit is then moved back to the starting point (8).

Abstract: Method and apparatus for pressing a parison. A parison mold is composed of neck tool halves and parison mold halves. A gob of molten glass had first been introduced through an upper loading orifice into a cavity of the parison mold, while a pressing plunger was located in a lower loading position. An assembly consisting of a pressing element, a guide sleeve and a piston-cylinder unit was introduced into the loading orifice. Subsequently the pressing plunger was raised from its loading position into the illustrated upper end operating position until its annular end face had moved into position against a stop surface of the neck tool. Following the preliminary pressing process a neck chamber in the cavity is still free from molten glass. It is only at this point that the pressing element exerts pressure on a base of the parison which is being produced. The molten glass is also pressed into the hitherto still free neck chamber of the cavity.

Abstract: Containers (2) arrive on a first conveyor belt (3) at comparatively large initial spacings (8) from one another and at comparatively high speed in a first direction of movement (4). The containers (2) are routed on a continuously curved path (11) into a second direction of movement (5) onto a second conveyor belt (6). Between the conveyor belts (3, 6) is arranged an intermediate belt (14) whose upper run (15) is driven in a third direction of movement (16) with a lower speed than the first conveyor belt (3). The second conveyor belt (6) likewise runs at lower speed than the first conveyor belt (3), so that finally a comparatively small second gap (7) results between the containers (2). A drive member (10) carries on the one hand transportation fingers (9) which engage between successive containers (2), and on the other hand stopping members (13) of a support device (12) with which the containers ( 2) are kept in continuous contact up to their delivery on to the second conveyor belt (6).

Abstract: An arrangement for adjusting the mass of gobs of thermoplastic material, especially molten glass, which are deformed in a positive manner in the mold of a molding machine by means of a pressing member which penetrates into the gobs. A distance transducer mechanically detects the maximum depth of penetration reached by the pressing member during each molding-machine operating cycle. The distance transducer is connected with a metallic actuating element for a differential transducer, at whose output is produced an electrical signal proportional to the maximum penetration depth reached, this signal being applied to an automatic regulating circuit which adjusts the setting of a dosing structure which controls the mass of the gobs.

Abstract: Each station has a push-off unit which transfers glass articles produced at such station onto a common outfeed conveyor. Each push-off unit comprises a cylinder-piston unit mounted for swinging movement on a vertical swing shaft, the piston thereof carrying a push-off arm. The push-off arm extends and engages the articles to be transferred, the cylinder swings towards the belt transferring the article, and the push-off arm retracts and the cylinder swings back. The push-off units of the plural stations are activated sequentially, in correspondence to the sequence in which glass gobs are fed into the respective machine stations. Plural electric motors are provided, one per station, and the swing motion of the push-off unit is generated by the respective electric motor. The rotation of each electric motor is controllable, by open- or closed-loop control, independently of the other electric motors. The operator selects the sequence in which the electric motors are to be activated.
