  • LATERALLY ADJUSTABLE SIDE GUIDE ASSEMBLY FOR USE WITH FRICTION SHEET FEEDING MACHINES
    Publication number: 20090096157
    Abstract: A laterally repositionable side guide assembly for use with a friction sheet feeding machine. The side guide assembly includes (i) a support member, (ii) a carriage, (iii) a side guide, and (iv) a worm screw. The support member is configured and arranged for attachment to a friction sheet feeding machine. The carriage is repositionably mounted on the support member for selective lateral repositioning relative to the support member. The side guide is configured and arranged for laterally guiding sheets through a friction sheet feeding machine. The side guide is attached to the carriage for lateral repositioning with the carriage. The worm screw is in threaded communication with the carriage for effecting linear movement of the carriage along the length of the worm screw upon rotation of the worm screw.

  • Friction sheet feeding machine with reversible driven retard roller
    Patent number: 6932338
    Abstract: A friction sheet feeding machine having (i) a tray for holding a stack of sheets, (ii) a driven friction feed roller for contacting a downward facing major surface of a lowermost sheet in a stack retained within the tray and pulling the lowermost sheet in a machine direction from underneath the stack, (iii) a reversibly driven friction retard roller vertically spaced in parallel relationship above the friction feed roller for contacting a leading edge and any exposed upward facing major surface of a sheet immediately overly the lowermost sheet so as to retard advancement of the overlying sheet, (iv) a first motor operably connected to the friction feed roller for driving the friction feed roller, and (v) a second motor operably connected to the friction retard roller for driving the friction retard roller, wherein the first and second motors are operably associated such that the second motor is operational only when the first motor is operated.
