Abstract: Systems and methods are disclosed for controlling the rotation of turrets with servo motors within a machine line used in the shaping of articles. Error conditions can be detected using the servo motors for resolving issues with the machine line. Control of the turrets by the servo motors allows for each turret to be rotated relative to the other turrets independently for resolving the issues. Absolute encoders are used to return the servo motors and their respective turrets back to being aligned with a virtual axis for synchronous rotation of the turrets within the machine line, despite the turrets not being mechanically coupled together by a series of gears.

Abstract: A defect tester for detecting a defect in an article in a machine arrangement includes a starwheel having one or more pockets configured to hold respective one or more articles. The defect tester further includes one or more disks. Each of the one or more disks has one or more openings. Each of the one or more openings includes a covering configured to form a seal with an open end of the article. The defect tester further includes one or more detector units configured to detect a range of radiation wavelengths in an interior of the article. The radiation wavelengths are directed on an exterior of the article. The one or more detector units are further configured to communicate to a controller whether a defect has been detected.
