Abstract: A sterilization system for sterilizing surface areas of a packaging material in a packaging machine is set forth. The sterilization system comprises an ultraviolet lamp including a housing and an ultraviolet light transmission portion. A support assembly is connected to support the ultraviolet lamp. The ultraviolet lamp is connected to the support assembly so that it is pivotable with respect to the support assembly from a first operating position in which the ultraviolet transmission portion of the ultraviolet lamp is disposed to irradiate the surface areas of the packaging material and a second position in which the ultraviolet transmission portion of the ultraviolet lamp is disposed at an angle for cleaning or service. A latching mechanism may be used to secure the ultraviolet lamp in the second cleaning position. Alternatively, the ultraviolet lamp assembly may be automatically moved between the first and second positions using an automatic drive.

Abstract: A workpiece holding apparatus for spindle finishing machines and the like, the apparatus including a plurality of radially arranged workpiece holders mounted for rotation about a first axis and including cooperating gear elements for rotating each of the holders about its respective longitudinal axis in response to rotation of the entire assemblage of holders about the first mentioned axis; a cam arrangement is provided whereby each of the holders may be actuated between a first condition securing workpieces on the holders and a second condition permitting workpieces to be removed, such as after a finishing operation has been completed.
