摘要：
A process and apparatus for depositing particulate material in a predetermined pattern onto a moving surface is disclosed. A particulate material may be fed under gravity from a hopper to a discharge zone containing a feed opening. A gas may be supplied, by a gas supply assembly, under pressure to the bulk of particulate material within the hopper discharge zone. The particulate material may be transferred through the feed opening to the surface of a transfer device, which contains a pattern of particulate-receiving recesses. The transfer device may rotate to a deposition zone and transfer the particulate material to a carrier layer.
