ABSTRACT:
A sheet feed assembly for feeding sheets from a stack comprises a vacuum feed device which is movable to feed a sheet from the stack in the feed direction while the sheet is held on the feed device under vacuum. A sheet holding device is spaced from the vacuum feed device adjacent the stack in use for selectively preventing sheets from being fed from the stack. A control device coupled to the vacuum feed device and to the sheet holding device selectively supplies a vacuum to the vacuum feed device to cause the device to feed a sheet and, at substantially the same time, to deactivate the sheet holding device so as to allow a single sheet to be fed by the vacuum feed device.
