Abstract
A conveying system for pneumatically conveying fragile, light weight workpieces by timed pulses of compressed air. Each pulse of air is used to propel a workpiece along a path that leads into a downwardly sloping chute and to decelerate the workpiece after it travels a selected distance down the chute so that all the initial momentum given the workpiece by the pulse of air is removed such that the workpiece will continue down the chute only under the influence of gravity. By decelerating or retarding the propelled workpiece it is prevented from impacting against queued workpieces, that proceeded it down the chute, with a high velocity that can cause breaking, chipping or jamming of the workpieces.
