    • The present invention relates to a process for depositing particulate material in a predetermined pattern onto a moving surface comprising the steps of: feeding the particulate material under gravity from a hopper to a discharge zone containing an feed opening; supplying a gas under pressure to the bulk of particulate material within the hopper discharge zone; transferring the particulate material through the feed opening to the surface of a transfer device, wherein the outer surface of the transfer device contains a pattern of particulate-receiving recesses; rotating the transfer device to a deposition zone and transferring the particulate material to a carrier layer. The present invention further relates to an apparatus comprising: a hopper comprising a discharge zone, the discharge zone comprising a feed opening, and wherein the discharge zone further comprises a gas supply assembly to supply gas under pressure into particulate material within the discharge zone; a transfer device adjacent to the feed opening, wherein the outer surface of the transfer device contains a pattern of particulate-receiving recesses.
    • 本发明涉及一种将预定图案中的颗粒材料沉积到移动表面上的方法,包括以下步骤:在重力下将颗粒材料从料斗送入包含进料口的排放区; 将压力下的气体供给料斗排出区内的大部分颗粒材料; 将颗粒材料通过进料口转移到转移装置的表面,其中转移装置的外表面包含颗粒容纳凹槽的图案; 将转移装置旋转到沉积区并将颗粒材料转移到载体层。 本发明还涉及一种装置,包括:料斗,其包括排放区,排放区包括进料口,并且其中排出区还包括气体供应组件,用于在压力下将气体供应到排放区内的颗粒材料中; 与所述进料口相邻的传送装置,其中所述传送装置的外表面包含颗粒容纳凹槽的图案。
