Abstract
A device for feeding sheets of a recording medium from a stack to an office machine, having movable elements which are moved by way of driven continuously rotating traction devices in the feed direction over the respective top sheet of the stack. The movable elements are supported by guide skids and are in contact with the top sheet under pressure to separate the top sheet from the second sheet of the stack beneath it and displace the top sheet with respect to the second sheet in the direction of feed. The movable elements each have at least one roller arranged across the direction of feed, mounted so it can rotate freely on a traction device.
Claims14
A device for feeding sheets of a recording medium from a stack to an office machine, comprising:
- one or more shingling elements adapted to be moved along a non-circular path including a substantially linear portion extending parallel to the top sheet by one or more driven, continuously rotating traction belts in the feed direction over the respective top sheet of the stack, the shingling elements being in contact with the top sheet under pressure to separate the top sheet from the second sheet of the stack beneath it and displace the top sheet with respect to the second sheet in the direction of feed, wherein the shingling elements each have at least one roller arranged across the direction of feed, mounted so it can rotate freely on an axle, and the axle being secured on at least one traction belt and adapted to move slidably along at least one fixed, elongated guide skid extending in the feed direction, spaced apart from the top sheet and facing the top sheet of the stack.
A method of separating a top sheet from a stack, comprising:
- moving at least one shingling element along a non-circular path, said path including a substantially linear portion extending parallel to the top sheet in a direction of feed;
- and
- contacting said shingling element with the top sheet under pressure to separate the top sheet from the second sheet of the stack beneath it and displace the top sheet with respect to the second sheet in the direction of feed.
A device for feeding sheets of a recording medium from a stack to an office machine, comprising:
- at least one shingling element adapted to be moved along a non-circular path including a substantially linear portion extending parallel to the top sheet in a direction of feed;
- and
- shingling element driving means for moving said shingling element in the feed direction over the top sheet of the stack,
- wherein the shingling element is adapted to contact the top sheet under pressure to separate the top sheet from the second sheet of the stack beneath it and displace the top sheet with respect to the second sheet in the direction of feed.
