Abstract: There is disclosed a vacuum table (400) comprising a vacuum plate (402) separating a first vacuum chamber (406) from a substrate zone (60) for receiving a substrate (50). The vacuum plate has a plurality of suction holes (404) for conveying a gas flow from the substrate zone (60) to the first vacuum chamber (406). There is an evacuation port (422) in communication with a second vacuum chamber (420) to evacuate gas from the substrate zone (60) when a substrate (50) is received over the suction holes (404) of the vacuum plate (402), and a vacuum port (424) for discharging gas received in the second vacuum chamber (420) to a vacuum source. The first vacuum chamber (406) and the second vacuum chamber (420) are in fluid communication via a valve (430) so that gas flows from the first vacuum chamber (406) to the vacuum port (424) via the second vacuum chamber (420). The valve (430) is controllable to vary a gas flow rate through the vacuum plate (402) and thereby vary a retaining force on a substrate (50) received thereon.

Abstract: A sheet handling device for a printer, such as a silkscreen printed circuit card printer, includes a pick-up and hold device that translates between a register position on the printer and one or more stacks of cards. Adjustable limit switches on a transport track for the device determine the positions at which its movement is interrupted. Plural knobs on a controller for the device are each assigned to one of the operations of picking up or releasing a card, and is set to one of the positions of the limit switches. The controller senses the assigned operation and position setting of each knob in sequence, and carries out the card transport operations accordingly.
