Abstract
The apparatus comprises a vacuum channel (15), and two parallel endless belts (3), which extend on opposite sides of said vacuum channel. The working courses (3a) of said belts have forward surfaces which extend substantially in a common plane (6). The belts (3) are synchronously driven in the same direction. The vacuum channel is provided on the forward side of an elongate carrier (1) and communicates through at least one suction port (21) with a vacuum source. The working course (3a) of each of said belts (3) is in contact on the rear with backing rollers (14).
Claims34
In apparatus for a slipless conveyance of discrete articles, particularly of glass plates in a predetermined direction of travel, comprising
- an elongate carrier, which extends in said direction of travel and has a forward side and is provided on said forward side with a vacuum channel, which is forwardly open and has at least one suction port,
- a vacuum source communicating with said suction port,
- two parallel endless belts, which extend on opposite sides of said vacuum channel in said direction of travel and comprise each a working course, which has a forward surface, said forward surfaces extending substantially in a common plane of travel and being adapted to contact one of said discrete articles so as to receive all the suction force exerted on the discrete articles, and which working courses are so arranged with respect to the vacuum channel that they form sealing elements to laterally seal the vacuum channel where it is covered by the discrete articles, and
- drive means operable to move both said belts in said direction of travel at the same velocity, and a plurality of backing rollers are provided, which are in contact with said working course of each of said belts on the rear thereof.
