Abstract: A detecting member for the height of the box with open side flaps is mounted in a vertically variable position on the closing assembly for the top flaps and is connected mechanically to the drive device which draws together the box conveyance units. In this manner drawing together of the conveyance units until they engage the sides of the box causes a corresponding movement of the detecting member which arranges itself in a position dependent upon the width of the box. Fall of the closing assembly starts simultaneously from a raised neutral position and continues until engagement of the detecting member so arranged with the top of an open side flap of the box. Braking means then stop the fall of the closing assembly. Appropriate sensitive means start operation of the closing assembly for the rear flap on the basis of the box length.

Abstract: A method and apparatus for increasing the performance and through-put of a high speed horizontal wrapping machine of the type having mechanically independently driven infeed, film drive and cut/seal head motors, each controlled by a shared programmed microprocessor whereby in the event that a product to be wrapped gets out of registration to the point where the machine's cut/seal head blades might otherwise engage the product being wrapped rather than only the film between two adjacent products, the condition is sensed and a software routine is called which causes the cut/seal heads to come to a stop in the open condition while the film tube continues to be fed until all the products, including the one out of registration and all those downstream from it, exit the wrapper, at which point the wrapper resumes its normal running mode. In this fashion, damage to the cut/seal head and associated down-time to clear the jam is avoided.

Abstract: An apparatus and method for transferring elongated parts, such as spark plug insulator bodies, travelling in a single row, end to end, on a first conveyor to a receptacle travelling on a second conveyor, the parts being placed each in a part-holding cavity in an insert in the receptacle, the part-holding cavity being disposed in consecutive rows. A part pick-up member picks up parts one at a time at the end of the first conveyor and transfers each part to the receptacle in which the part is placed substantially vertically with its end in a part-holding cavity in the insert. Sensors distinguish between good and defective parts at the location where the parts are picked up at the end of the first conveyor such that defective parts are rejected and the part pick-up member picks up only non-defective parts. Sensors detect fallen-over parts in the receptacle and stop loading in the event that parts are not properly placed in the holding cavities in the receptacle insert.
