  • Contact-free plate conveyor
    Patent number: 7108123
    Abstract: In a contact-free plate conveyor including an arrangement of nozzles each having a cup-like shape widening to a planar rim thereof, air under pressure is supplied to the nozzles such that an air flow is generated toward and through a gap formed between the rims of the cups at high speed which generates a vacuum between the cup rims and the plate so as to hold the plate at a predetermined distance from the nozzle arrangement.

  • Transport diverter for plate material conveyor, particularly a plate glass conveyor
    Patent number: 6669003
    Abstract: In a transport diverter for diverting plate material from a supply conveyer to take-off conveyor branches, the transport diverter comprises a series of short conveyor segments, which can be raised in unison for the transfer of a plate from the supply conveyor to a conveyor takeoff branch, which extends at a higher level than the supply conveyer, and which can subsequently be lowered individually one after the other to the level of the supply conveyor as the plate moves off the conveyor segments.
