APPARATUS FOR DEPOSITING FLUID MATERIAL ONTO A SUBSTRATE

摘要

Apparatus for depositing fluid material onto a moving substrate includes at least two nozzle units (N1, N2) substantially aligned along a direction of alignment. The nozzle units are mounted on a transfer plate (TP) secured to a manifold (159) used to deliver fluid material to the nozzle units. The transfer plate is mounted on the manifold by a mounting system (211, 215) which allows adjustment of the transfer plate position (and nozzle units thereon) relative to the manifold in the direction of alignment. Supply ports (SP1, SP2) in the manifold remain in fluid communication with a number of stacked supply channels (SC) in the transfer plate during such adjustment. In another embodiment, recirculation units (R1, R2) are attached to the transfer plate. The transfer plate has an inflow recirculation passage providing fluid communication between the manifold supply ports and the recirculation units and an outflow recirculation passage providing fluid communication between the recirculation units and return ports of the manifold.
