Abstract
A sorting machine is disclosed based on a procedure utilizing standard length pulses initiated by the sensing of the leading edge of a sensed product and rejecting a defective product based on sensing where its trailing edge is or should be if covered up by a successive overlapping product. Such detection allows for rejecting products that are either too long or too short. The detection of the trailing edge location also is employed for the activation of a reject mechanism operated on a fixed delay from the occurrence of a defect signal for whatever reason produced from the sensing of a product in the product stream.
