  • Patent number: 4096937
    Abstract: An article transport system employs a rail assembly and a holder rotatably mounted on a conveyor. The assembly is comprised of a series of interconnected, axially-aligned, generally cylindrical members, which are relatively free to move independently of one another. Relative movement of the holder and rail assembly causes, through frictional engagement therebetween, the uniform rotation of an article mounted on the holder; the system has particular utility for transporting decorated can shells through ultraviolet curing ovens.

  • Patent number: 4037329
    Abstract: A shutter, adapted for use in a system for the radiation curing of a line of articles, includes a number of adjacent baffle units, the blades of which are configured and spaced to substantially prevent the passage of radiation, while permitting the flow of air through the shutter. To minimize the tendency of thermal expansion to distort the shutter, the units are expandably mounted along the length of the supporting frame, and the blades extend transversely thereof.
