ABSTRACT:
Apparatus for registering a pair of rectangular sheets includes a rectangular sleeve whose width is variable, and a retractable gate located at one end of the sleeve. In a first embodiment, fluid injected into the other end of the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls of the sleeve, and register the other of the sheets with the gate and the other narrow wall of the sleeve. In a second embodiment, the sheets are registered against a centrally disposed vented manifold and the gate. In a third embodiment, fluid drawn into the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls, and register the other of the sheets with the gate and the other of the narrow walls.
