Disclosed is a method for controlling a conveyor for conveying hollow bodies through a hollow-body heating station including: &#x2014;a heating tunnel defining a heating path, &#x2014;a conveyor including at least one travel track and shuttles capable of moving along the track while picking up at least one hollow body, the movement of each shuttle being controlled individually, &#x2014;a travel-track loading portion on which two consecutive shuttles move at a first predetermined input separation, and a travel-track unloading portion. Two consecutive shuttles moving on this unloading portion are spaced apart by a predetermined output separation that is different from the first input separation.

Method for controlling a conveyor for hollow bodies through a heating station and associated conveyor

A mould carrier unit having a stretching rod () borne by a slide () mobile between an inactive position and an active position where its free end reaches the bottom of the mould (); a nozzle () including a fixed body () extended by a bell (), which is mobile from an inactive position where its free edge () is held substantially at the same level as the free end () of the stretching rod () to an active position where it is sealingly applied against the inlet surface () of the mould (), to close the circuit of the blowing fluid. The bell () includes a bar () provided with a stop (), which stop () cooperates with a support () formed on the slide () to permit the bell () to pass from its active position to the inactive position with the same law of motion as the stretching rod ().

Disclosed is a blowing device () for forming containers () from thermoplastic material preforms. The device () includes a blowing nozzle () including a bottom outlet opening () for a pressurized blowing fluid to leave along a vertical outlet axis () and a single duct () for supplying the nozzle () with blowing fluid that leads into the nozzle (), via a top supply opening (), along an axis that is completely radial relative to the outlet axis (A) of the nozzle (). The blowing device is characterized in that the upstream end section of the supply duct () leads into the nozzle () along a branching axis (B) that forms an obtuse angle (a) with the outlet axis (A) of the nozzle () such that the blowing fluid leaving the supply duct () is directed downward.

Blowing device comprising a nozzle and a supply duct forming an obtuse angle

The mould carrier unit for manufacturing containers by a stretch blow-moulding operation of preforms () arranged in moulds (), comprises: and said bell () comprises a bar () provided with a stop (), which stop () cooperates with a support () formed on said slide () to permit said bell () to pass from its active position to the inactive position with the same law of motion as said stretching rod ().

Method for changing the pitch between discrete entities conveyed in succession between a device for feeding the entities at an initial spacing pitch provided between two entities fed in succession and a device for receiving the entities at a final pitch substantially greater than the initial pitch. The method including transporting the discrete entities by a variable pitch feed screw device configured to receive the entities downstream of the device for feeding the entities, the screw including a groove in which the entities are capable of being housed and displaced, so that the pitch between two entities received by the screw is increased downstream of the screw as far as an intermediate pitch; and transferring and gripping the entities at the intermediate pitch by a wheel for changing the pitch, configured to transfer the entities into the receiving device at the final pitch.
