Abstract
A method for positioning articles to be processed by a machine is performed by apparatus comprising first and second article guide members which convergently extend into an article entryway along which articles are conveyed. The guide members are spring biased into an article positioning orientation across at least a portion of the entryway and maintained in that article positioning orientation by first and second levers extending beneath the article entryway and including an interlock. The interlock releases the article guide members only upon an article contacting both of the guide members. The interlock comprises a release slot and at least one locking notch extending from one side of one end of the slot on one lever and a pin for engaging the slot and locking notch on the other lever. When the pin is engaged in the locking notch, the first and second guide members are retained in a package positioning orientation such that an article engages one or the other of the package guides and is moved laterally to a desired position by the guide as the article is conveyed along the entryway. Upon engaging both guide members, the pin is removed from the locking notch and moves within the slot to release the guide members and permit the positioned package to progress along the entryway toward a processing station of the machine.
