Abstract

In transporting sheets of paper it is useful to be able to accurately position them in the direction of travel. Reg-istration, as this is called, may be accomplished either against a moving barrier if the sheet is to subsequently be carried elsewhere, or against a fixed barrier if the stream of sheets is to be assembled into a stack. In either case, over-driving the sheet enough to get reliable registration tends to buckle the sheet.

In transporting sheets of paper it is useful to be able to
accurately position them in the direction of travel. Reg-
istration, as this is called, may be accomplished either
against a moving barrier if the sheet is to subsequently be
carried elsewhere, or against a fixed barrier if the stream of
sheets is to be assembled into a stack. In either case, over-
driving the sheet enough to get reliable registration tends to
buckle the sheet.

The arrangement shown provides adequate and controllable drive
force while constraining the sheet against buckling. Driving
force on the stack (3) is provided by the idle roller (4) due
to its weight and the weight of the connecting link (1) . Force
is also provided at the registration station (5) by the slight
wrap of the feed belt (6) and the tension on the belt. The
tension on the feed belt (6) is set by the counterweighted
link (2) . Alternately, the use of gravity for loading could
be supplanted by springs.
