    摘要： An apparatus and method are disclosed for inspecting a series of can ends as they come off a forming press wherein the can ends are carried on a continuous belt which moves them through the forming press and then past a light source and a light detecting means which senses any light passing through each of the can ends as they are presented seriatim to the light source and sensing means. The light source is fixedly positioned on one side of the continuous belt and the sensing means is fixedly positioned on the other side of the belt. An extensible bellows, sealed against the light sensing means, is connected to a ram on the forming press which extends and contracts the bellows into and out of light tight sealing engagement with each of the can ends as it is presented for inspection. The light source and the light sensing means are both activated when the bellows is in light tight engagement against a can end to expose one side of the can end to light and sense whether any light passes through such can end.

    摘要： Method and apparatus for detecting insecurely glued closure flaps on wrap-around paperboard cartons and for diverting defectively sealed cartons from the packaging line. A striking device in the form of an impact roller strikes the leading edge of each carton as it moves along a conveyor belt. Loose or insecure flaps opened by the impact are detected as the carton passes through a photocell station. Upon identification of an open flap condition a pivotal eject chute forming a part of the conveyor table is actuated downwardly to divert the rejected carton to a remote location for inspection and resealing or replacement.
