Abstract
A stalled roll registration system includes a mechanism that allows for pivoting deskew action in a pre-registration nip. A ball-on-roll pre-registration transport is used in combination with a stalled roll registration nip. Any initial buckle is depleted rapidly as the body of a sheet straightens out at the registration nip under the influence of the ball-on-belt transport.
Claims11
An apparatus for registering a sheet in a path, comprising:
- a registration nip located in the path;
- and
- a rotationally compliant input pre-registration transport, and wherein said rotationally compliant input pre-registration transport includes at least one ball-on-belt nip that facilitates sheet pivoting therein.
A printing machine in which a sheet is driven along a path and fed in a timed relationship and registration position to a process station, comprising:
- a registration nip located in the path;
- and
- a ball-on-belt input transport that facilitates pivoting of a sheet therein in order to register a sheet within said registration nip.
A method for registering a sheet transported in a path to a downstream registration location, comprising:
- providing a registration nip located in the path;
- providing a ball-on-belt input transport;
- feeding a sheet into said registration nip with said ball-on-belt transport;
- and
- pivoting the sheet within said ball-on-belt transport in order to register the sheet within said registration nip.
