Abstract: An electrostatic document copying system which includes an electrostatic plain paper engineering copying machine having a copy paper feed rack secured thereto, and copy paper guide channels adjustably secured thereto in copy paper-receiving alignment with copy paper rolls supported on the feed rack. The copy paper feed rack includes a frame attachable to the copier, and carrying a plurality of cantilevered, telescoping copy paper roll-supporting arms. These arms are individually selectively extensible. They are arranged to cooperatively cradle and support a plurality of continuous copy paper rolls to facilitate simultaneous feeding of copy papers from multiple rolls. A plurality of original documents can thus be simultaneously copied. The apparatus is especially adapted for copying elongated oversized documents, such as oil well logs.

Abstract: A system for passing long fan-folded documents and corresponding copy paper through a reproducing apparatus and including a collapsible, upright stand which carries a pair of copy paper roll supporting elements, a pair of paper guide plates pivotally and detachably connected to the top of the stand, and a guide bar for guiding copy paper from a roll on the stand to the guide plates. The system further includes an improved, two-part feed tray detachably mounted on the reproducing apparatus. Each part is selectively positionable on the reproducing apparatus to facilitate containment of a fan-folded document to be reproduced. Each feed tray part includes a base plate having a downwardly extending strap to locate the tray on the reproducing machine, and at least one upwardly projecting stop rib spaced from a paper discharge slot at the front side of each tray part, and acting as an indexing abutment for contacting and positioning the fan-folded document in the tray.

Abstract: A system for passing long fan-folded documents and correspondingly lengthy copy paper through a reproducing apparatus, and including a frame attachable to the reproducing apparatus and adapted to support a roll of copy paper, and further including a feed tray detachably mounted on a reproducing apparatus and having a partition plate selectively positionable in the feed tray to facilitate containment in the tray of a fan-folded document to be reproduced. The feed tray includes a bottom plate having downwardly projecting ribs to detachably mount the tray on the reproducing machine, and upwardly projecting ribs spaced from a paper discharge slot at the front side of the tray, and acting as an indexing abutment for contacting and positioning the fan-folded document in the tray. The copy paper roll supporting frame has mounted thereon a cutting wire detent stud and a pivotable cocking lever. A spring biased cutting wire has one end connected to the supporting frame and its other connected to the cocking lever.

Abstract: A system for passing long fan-folded documents and corresponding copy paper through a reproducing apparatus either concurrently or independently of each other, and including a collapsible, upright stand which carries a pair of paper roll supporting elements, a pair of paper guide plates pivotally and detachably connected to the top of the stand, and a guide bar for guiding paper from a roll on the stand to the guide plates. The system further includes a feed tray detachably mounted on a reproducing apparatus and having a partition plate selectively positionable in the feed tray to facilitate containment in the tray of a fan-folded document to be reproduced. The feed tray includes a bottom plate having downwardly projecting ribs to detachably mount the tray on the reproducing machine, and upwardly projecting ribs spaced from a paper discharge slot at the front side of the tray, and acting as an indexing abutment for contacting and positioning the fan-folded document in the tray.

Abstract: A method and system for producing elongated Z-fold copy paper having indicia emplaced thereon by xerographic reproduction. The method entails initially transversely scoring and folding an elongated sheet of paper at spaced intervals therealong with alternate adjacent score-fold lines being originated by pressures exerted on respectively opposite sides of the paper. The elongated scored sheet is then rolled up in a cylindrical roll, and is fed from this roll to a copying machine into close proximity to a rotating xerographic copying drum within the machine. After emplacement of indicia on the paper in the reproduction process, the paper may then be rolled up on a storage roll or Z-folded manually or by suitable apparatus.

Abstract: An apparatus for concurrently feeding elongated documents and substantially correspondingly sized copy paper to a reproducing apparatus which includes a collapsible, vertically extending A-frame having a pair of opposed, divergent sides each of inverted U-shape, and pivotally interconnected at the tops thereof. One of the sides of the A-frame journals a horizontal, paper roll-supporting element, and the other side of the frame carries a horizontal paper guide bar. At the upper side of the A-frame, the frame detachably supports one end of an elongated document-supporting tray which is adapted to support and feed a collapsed and folded original fanfold document of multiple superimposed layers. The other end of the document-supporting tray is aligned with feed rolls of a reproducing apparatus used to feed the document to be copied or reproduced to the reproduction section of the apparatus.
