Abstract: A container treatment machine having a frame, a table top inclined to the horizontal being attached to the topside so that at least one collecting opening for fluids, container fragments or similar foreign bodies is formed in the table top, and the areas of the table top connected to the collecting opening are inclined with a downward slope to the collecting opening.

Abstract: A blow moulding machine comprising a heating wheel provided with a plurality of reception means for preforms and having a substantially vertical axis of rotation, and a blow wheel provided with a plurality of blow stations for hollow bodies such as for bottles, and having a substantially vertical axis of rotation. The heating wheel and the blow wheel are arranged on different levels and overlap each other at least partially. The preforms are moved from the level of the heating wheel to the level of the blow wheel by means of a transfer device. A substantial reduction of the floor space and of the production costs for the blow moulding machine is achieved in this way.

Abstract: An inspection machine for transilluminatable bottles inspects the sidewalls of bottles by transmitting a diffused beam of light through the sidewall and using a plurality of mirrors appropriately arranged for detecting or recording the images emergent from the bottle in different directions in the same image recording camera. The arrangement requires at least two separate beam paths and mirrors in each path directing the bottle emergent beams to the camera while the bottles are being conveyed through a position in which they are illuminated. In an improved arrangement, there is a separate cooperating series of beam deflecting mirrors which generate at least three independent beam paths that impinge from different directions on the sidewall of the bottle being inspected. The recording device is preferably a camera having a charge coupled device image plate.

Abstract: Bottles made of transparent plastic material or glass are subjected to at least one stationary examination device and further for detecting impurities or damage to the bottom, side wall or mouth regions of vessels. To be able to detect defects which may cause the bottles to leak, and which cannot be detected reliably by optoelectronic devices, the vessels are inspected additionally using a leak test by developing pressures.

Abstract: First, second and third linear conveyors are arranged in alignment with each other in the stated order. Bottles to be inspected are conveyed standing on their bottoms on the first linear conveyor through an inspection station followed by an ejector for those bottles which fail to match specified characteristics of an acceptable bottle model. The second conveyor has spaced apart parallel translating conveyor belts for frictionally gripping the bottles by their bodies between them to make their mouth ends and bottoms clear for inspection. The bottle discharge end region of the first conveyor and the bottle inlet end region overlap to achieve an overall shorter machine. The second conveyor has a bottle discharge region that overlaps the bottle inlet end region of the third conveyor to achieve a shorter machine.

Abstract: Empty bottles are checked for foreign bodies and other contamination by passing the bottles successively through two inspection zones in which they are optoelectronically scanned while they are on rotating disks that are mounted on a rotating table. When in one inspection zone a bottle is held stable on the disk by a rotatable socket that grips the bottle mouth to allow a clear view for inspecting down to the bottom. When in the other inspection zone the bottle is engaged by a ring at about shoulder height so there is a clear view for inspection of the bottle portion from the shoulder to the mouth. In transition regions between inspection zones the ring and socket both engage the bottle for a moment and then one gripper is withdrawn while the other remains to hold the bottle in the forthcoming inspection zone.
