Abstract: An inverter unit for a hollow glassware forming machine comprises a supporting structure; a first and a second pick-and-place arm having one or more recesses for picking up glassware and coupled to such supporting structure so as to rotate about a first axis and so as to translate along such first axis between an open position and a closed position; and a centering device having a head, which can rotate about a second axis. The centering device also has a transmission mechanism, which converts the rotary motion of the head into a translational motion of the supporting structure along the first axis with respect to a fixed base.

Abstract: An assembly for controlling the weight of a glass gob on a glassware molding machine has a punch for at least partly penetrating the gob and controlled by a fluidic linear actuator having an outer sleeve of paramagnetic material, and a piston which slides inside the sleeve; the piston being connected integrally to the punch; and movement of the piston being controlled by a linear transducer having a movable member fitted to the piston, and a fixed member located outside the sleeve.

Abstract: The present invention relates to a system for aligning and positioning a male mechanism-pneumatic or servo-electric-to be used at the blank station side of a section of a hollow glass forming machine. The system comprises a mechanism, comprising at least one plunger or a driving unit driven by a servomotor, a guide flange composed of an internal flange for retaining the mechanism in position, and an external flange. The system further comprises a base plate for supporting the mechanism. The plate is mounted on at least one guide bar, rigidly fixed to the resting face of the external flange and intended to allow the base plate to slide along a sliding direction substantially orthogonal to the plane wherein the external flange lies. The base plate rests on a height adjustment group, suspended to said upper plane and intended to move the plate along the guide.

Abstract: An infeed mechanism for a glass container inspection machine which will receive bottles on a linear conveyor and which has a support to which the infeed mechanism can be secured. The infeed mechanism has a timing cam and a frame is provided for supporting the timing cam at the bottom thereof which includes a first box like frame for rotatably supporting the timing cam at the bottom, a servo motor secured to and within the first box like frame, a vertically extending transmission supported by the first box like frame for transferring the output of the servo motor downwardly to the rotatable timing cam, a second frame, above the timing cam for supporting first frame for relative vertical displacement, and a mounting plate located vertically above the second frame for supporting the second frame for relative horizontal displacement transverse to the linear conveyor so that the infeed mechanism can be mounted by securing the mounting plate to a machine frame with the infeed mechanism above the linear conveyor.

Abstract: A glass container inspection machine which has a machine frame having a horizontal upper portion, a horizontal lower portion, and a vertical portion interconnecting the horizontal upper and lower portions for defining a rear, side to side, stepped in configuration for defining a volume into which a linear conveyor can be located by displacing the inspection machine frame rearwardly. An infeed mechanism is suspended from the horizontal upper portion above the linear conveyor when the frame is displaced rearwardly to locate the linear conveyor in the volume, and an outfeed mechanism is suspended from the horizontal upper portion above the linear conveyor when the frame is displaced rearwardly to locate the linear conveyor in the volume.

Abstract: An on-off valve for use in an air line of a cooling system of a glass container manufacturing machine comprises an integral frame defining an opening, a generally planar sealing member adapted to engage the frame, and a piston and cylinder device which moves the sealing member perpendicular to its plane between an open and a closed position.

Abstract: A transfer mechanism for transferring glass parisons in an I.S machine from a blank station to a second station comprises two neck-ring mechanisms which operate alternately. While one neck-ring mechanism carries parisons from the blank station in a vertical plane to the second station, the other neck-ring mechanism rotates about a vertical axis to move out of the way of the first while moving from the second station back to the blank station.

Abstract: An arrangement in a glassware forming machine for connecting a supply of operating air to a mechanism mounted in a frame of the machine, which mechanism may need to be adjusted in position vertically in the machine comprises a flexible pipe which connects the mechanism to a supply of operating air, and a sleeve for permitting a change of length of the pipe so that adjustment of the mechanism can be accommodated.

Abstract: An operating mechanism for a glassware forming machine is located on a horizontal table of the machine. A locating sleeve is secured to a lower face of the table and serves to determine the vertical alignment of the operating mechanism while a clamping device determines the vertical location of the mechanism.

Abstract: A pneumatically operated mechanism for a glassware forming machine is located in an aperture in a top plate of the machine and comprises entry ports in a downwardly facing surface which mate with exit ports for air supplies located in an upwardly facing surface of the top plate.
