ABSTRACT:
Apparatus in the form of a vacuum bar for picking up a full row of newly formed glass containers from a moving conveyor on which the containers are sitting and transferring the containers onto a moving lehr mat. The container engaging system is formed of a pair of heat resistant, air impervious curtains that are supported in opposing relationship and are mounted to be movable toward and away from each other by the introduction of a vacuum to the area therebetween, from above, while they are positioned on each side of the row of containers, to cause the curtains to engage and grip the entire row of containers. The bar is moved with the containers to a position above the lehr mat and released thereto when the vacuum is interrupted, the bar elevated to clear the curtains from the containers, retracted into position above the cross conveyor and next full row of containers forming thereon preparatory to being picked by the vacuum actuated bar and curtains.
