ABSTRACT:
The pusher mechanism (14) associated with an I.S. glassware forming machine (10) are controlled by a controller (30) which provides control signals which cause the mechanisms (14) to operate. The controller senses the passage past a particular location of ware (1 to 6) of ware as it is transported by a conveyor (16) on to which the pusher mechanisms (14) transfer the ware. The controller determines the spacing (s1 to S5) on the conveyor (16) of ware from different sections (12) of the machine (10), compares the spacing with a predetermined, desired, spacing and, in the event that said spacing differs from said predetermined spacing by more than a predetermined tolerance, advances or retards the supply of control signals to at least one of the pusher mechanisms (14) which transfers the ware concerned.
