SU7307A1 - Fixture for simultaneous writing through multiple-copy carbon copy paper - Google Patents

Description

The proposed fixture, intended for simultaneous writing through multiple-copy copying paper, is shown in a schematic drawing, in which FIG. 1 shows the general scheme of the device, FIG. 2 is a longitudinal section and FIG. 3 is a plan view.

The tool is a box, part of which is designed to hold paper wrapped in several rolls, depending on the number of copies of the document desired. The other part of the device is a device, basically consisting of a support board O (Fig. 2), on which the strips of paper are separated by copy layers from each other. At this point, the instrument is written on top of a paper tape in the cut-out of the frame holding the paper, and the writing will be repeated on all underlying paper strips with 0 copy paper. There is a special knife for cutting paper.

Paper tapes I, unrolled from rolls V (Fig. 1), are superimposed one on another and are held between the gears d, d, dj, dj, (Fig. 3) of the compressive tapes. Passing the gears, the paper strips pass between the frame K that holds them (Fig. 2) and the support board O. During the passage between the frame and the support board, the paper strips are separated by leaves t (Fig. 1) of copying paper.

Frame K, which includes the top pair of gears d, d, mounted on separate axes C, C, the distance between which exactly corresponds to the distance between the wheels dj, 1, fixed in the support plate of the device O on axes (7i , C. The frame is rotated on loops xg, which serve to connect it with the base plate O and with the side wall [.] When the lower and upper pairs of gears engage with teeth, which thereby encompass the previously removed on the support board O paper tapes. TERM with this frame to its clamps and presses and acting on the edges of the paper tape copying layer, wider than the paper tape.

The frame has a handle for opening and a large inner cutout B (Fig. 3),

at. which is used to write a document, and a small cutout g, in which paper sheets are available for grip with your fingers. The clamps (jf and together with the bends, s supporting on the board O serve to smooth the paper strips after the gears. After the rolls are fixed in the drawer, the ends of the paper tapes are removed from them and through the slot X of the drawer are brought to the supporting board O) where between they are copied paper, after which the frame is locked (lowered). Having appeared between boards, paper tapes have an exact channel for movement. In the large cut-out of frame B, the paper is visible from above and is available for writing.
