ABSTRACT:
A flexible sheet stacker is described which includes a support surface disposed substantially at right-angles to a flowline along which flexible sheets are fed in spaced relationship. The support surface is adapted to support in a stack the leading edges of the successive sheets fed along the flowline. The pressure-member is arranged to contact a face of a first sheet fed to the support surface and is thereafter movable away from the flowline against biasing means as sheets are progressively fed to the support surface. A wedge shaped separation member is movable along a substantially rectilinear path in advance of a sheet approaching the support surface, the separation member contacting the face of the stack and maintaining the contact during rectilinear movement of the separation means up to the support surface, a face of the stack being thereby displaced laterally out of the path of the leading edge of the approaching sheet as the sheet is advanced up to the support surface.
