Abstract
This is a compiler tray with a Velcro® surfaced back guide enabled to be used with Birds Beak Edge Curl Suppressors to minimize up curl and down curl of sheets fed into the tray and improve Stapled Set Registration. The Velcro® is either fixed to the back guide or adjustably positioned on the back guide. The Velcro® is placed on the back guide in such a manner that the ribs and grooves of the Velcro® are at an angle significantly not parallel to the plane of the lead edge of paper sheets fed into the compiling tray.
Claims16
A finisher compiling tray or structure useful in a marking system which comprises:
- at least one paper sheets drive element,
- a compiler tray, and
- at least one set of bind edge curl suppressors acting perpendicular to the stack,
- said compiler tray enabled to collect and house a stack of said paper sheets,
- said compiler tray comprising a configuration with a tray base connected to a back guide or compiling wall,
- said compiling wall adapted to receive the leading edges of said stack of sheets, said compiling wall comprising a hook material of hook and loop-type fastener(s) surface which is set on said wall having its ribs and grooves at an angle not parallel to a plane of a lead edge of said paper sheets fed into said compiling tray,
- said bind edge curl suppressors configured to control bind edge quality for both up and down curl of said stack of sheets.
A finisher compiling station useful in a paper marking system which comprises:
- at least one paper sheet drive mechanism, a compiling tray and at least one set of bind edge curl suppressors acting perpendicular to the stack,
- said compiling tray comprising a back guide or compiling wall connected at one end to a tray base,
- said base tray having an open end adapted to allow paper to be pushed therein and its lead edge up against said compiling wall,
- said compiling tray adapted to receive and house a stack of paper, said compiling wall comprising a hook material of hook and loop-type fastener's surface attached thereto, said fastener's surface having a plurality of ribs and grooves set at an angle of from about 30-60 degrees from horizontal and not parallel to a plane of a lead edge of said paper, said bind edge curl suppressors cooperating with said fastener's surface in controlling the effect of down curled and up curled lead edges on said paper as it enters and stacks in said compiling tray and contacts said compiling wall.
