Abstract
Sidewalls of cans from one filling and closing line are magnetized to provide each with a north pole oriented toward the can top. Sidewalls of cans from another filling and closing line are magnetized to provide each with a south pole oriented toward the can top. These tagged cans are randomly merged into one line for further processing without mixing up can top orientations, for instance, for cooking in a conveyor-fed continuous cooker in order to keep the cooker operating nearer full capacity. Then, each can passes a magnetic sensing station where one (top) end of each can is investigated by a probe which senses whether that end is a north pole or a south pole. The sensing station commands a diverter downstream which shunts the cans sensed as having north pole ends into a different line from the cans sensed as having south pole ends.
