A sorter for sorting transversely-spaced articles moving along a direction of travel employs an array of fluid nozzles aligned transversely to the direction of travel for separating some of the articles from others, according to differences in their physical characteristics, by selectively directing respective streams of fluid toward some of the articles to deflect them from the direction of travel. The nozzles are arranged in a substantially linear transverse alignment relative to the direction of travel, each nozzle being connected to a respective selectively operable fluid supply valve. The valves are arranged in a nonlinear array in a common plane extending generally in the direction of alignment of the nozzles, and are connected to the respective nozzles by flexible tubes of equal length which interface the nonlinear array of valves with the linear transverse array of nozzles. The tubes are embedded in a hardened polymeric material which also forms the nozzles.
A sorter for detecting differences in physical characteristics of individual articles moving along a direction of travel while spaced transversely to said direction of travel, said sorter including an array of fluid nozzles distributed transversely to said direction of travel for separating some of said articles from others of said articles according to said differences in physical characteristics by selectively directing respective streams of fluid toward said some of said articles to deflect them from said direction of travel, at least a mutually adjacent group of said nozzles being aligned substantially linearly in a transverse direction of alignment relative to said direction of travel, each nozzle of said group being connected operatively to a respective fluid supply valve of a group of valves for selectively supplying or interrupting the supply of fluid to the respective nozzles in response to said differences in physical characteristics of said articles, said group of valves being arranged in a nonlinear array in a common plate extending generally in said transverse direction of alignment of said group of nozzles, and a group of flexible tubes, each interconnecting one of said valves with one of said nozzles, wherein said flexible tubes are embedded as a group in a mass of hardened polymeric material.
