Radioactive isotopes at relativistic energies: model predictions

In an inserting machine, guide apparatus for maintaining control of individual sheets and collations that are conveyed along a transport deck by at least one pair of pushers, comprises a mounting beam coupled to a frame member of the inserting machine, and a plurality of guide arms pivotally mounted at one end to the mounting beam and biased against the transport deck. Each of the guide arms has a second end resting against the deck between the pair of pushers. Each of the guide arms has a curved shape for engaging a collation gradually An idler roller is rotatably mounted to the second end of each of the guide arms. The mounting beam is pivotally mounted at one end to the frame member of the inserting machine, whereby the other end of the guide apparatus is pivotable away from the transport deck.
