    The present invention relates to an apparatus and method for making sheets from reinforced elastomeric ribbon. The apparatus has a lead-in mechanism on which the ribbon is received for preliminary orientation. The apparatus also employs a transfer mechanism that incorporates a shuttle head which is supported by a primary carrier disposed over the assembly mechanism. The shuttle head is capable of being protracted from its normal position over the assembly mechanism to a position over the lead-in mechanism where it is also engaged by a stabilizing carrier which assures precise orientation of the shuttle head during its operative movements with respect to the lead-in mechanism. So stabilized the shuttle head: engages and grasps the ribbon presented by the lead-in mechanism; raises the ribbon off the lead-in mechanism; retracts to position the ribbon above the assembly mechanism; and, accurately deposits the ribbon on the assembly mechanism. A guillotine mechanism severs the incremental strip deposited on the assembly table from the ribbon. After the shuttle head disengages from the incremental strip the guillotine mechanism is moved out of contact with the incremental strip so that the incremental strip can be transferred laterally by an indexing mechanism to the degree required for receipt of a successive incremental strip without inadvertent interference between the strip, or strips, being indexed and the guillotine. To achieve indexing the assembly mechanism employs a continuous belt that is accurately indexed by a unique arrangement of interacting brake and transport clamps. For most purposes, successive strips will be deposited in continguous, lateral juxtaposition, and in order that the successive strips stick together a stitcher is provided to cycle a stitching roller along the abutting edges of successively deposited incremental strips.

    This invention relates to the manufacture of a green cord used to make tires for pneumatic tires.
    A known method for the manufacture of rubberized cord fabric, in which rubberized tape is supplied with a longitudinal arrangement of reinforcing threads, is laid on the have-a. 1IJA transporting working surface of the docking table with a parallel arrangement of the longitudinal edges of the previous and subsequent sections of the tape, cut the ribbon by transversely cutting it at the trailing edge of the previous section, joining the subsequent and previous sections along the longitudinal edges and moving the working surface of the LINKING table in the direction of web selection to step corresponding to the width of the yi 1 supplied.
    A device for carrying out the aforementioned method comprises a docking table mounted on a frame with a working surface in the form of a driving belt conveyor, an introductory table, a cutting mechanism for cross cutting in the form of a guillotine mounted on a frame, a mechanism
    2
    for the step-by-step adjustment of the docking table and the feeding mechanism / including the supporting beam, the main supporting element moving along its assembly carriage for laying the cord band from the driving gear,. the table on the docking with the grip to hold the rubberized tape and the reciprocating drives vertical
    10 move the movable carriage 21.
    When implementing a known method on a known device, there is the possibility of interaction after cutting between the cut off section
    J5 and the ribbon or between the cut section and the lower knife. In this case, the reinforcing elements of the cut-off area and the tape are captured when the cut-off area is fed to the docking
     table that causes improper installation of at least part of the site. As a result of a proper, no engagement with the previous section on the docking herd occurs, therefore 25 iviy when joining there is no continuous web. It is necessary to stop the device in order to manually align these sections of the belt properly. The widespread use of metal reinforcement
    erne elements exacerbate this problem more. In addition, when the yarn is grabbed, the subsequent advancement of the tape by the feeding mechanism carriage is accompanied by a break.
    When cutting a KOHeii cut, the stock is often crushed or deformed, pressing against the bottom kn. Friction, see that section of the sheet. About the lower knife also leads to the wrong arrangement of consecutive sections of the tape.
    In the known device, the step-by-step movement mechanism of the docking table consists of a row of double action cylinders, which, when operated in the same direction, drive the gear rack, the rotating driven gear, and the corresponding conveyor means moves the docking table conveyor forward during the return stroke, during which the electric conveyor is released. It is released from the coupling means. Such a structure does not provide an accurate movement of the docking table at a predetermined pitch, which also leads to improper placement of the cut sections on the docking conveyor. -.
    All of the above disadvantages lead to a decrease in the quality of the rubberized cord fabric.
    The aim of the invention is to improve the quality of rubberized cord fabric.
    This is achieved by the fact that when implementing the method of manufacturing rubberized cord fabric, in which the rubberized tape with longitudinal reinforcement yarns is placed, it is placed on a connecting table with a parallel arrangement of the longitudinal edges of the previous and subsequent uchestkov tape, which has a transporting working surface, cutting the ribbon at the level of the rear edge of the previous section, join the next and previous sections along the longitudinal edges and move the working surface the docking table in the direction of selection of the web by a step corresponding to the width of the fed tape, after transverse cutting of the tape, first take it away from the cut section, and then move the working surface of the butt-end table.
    In the case of transverse cutting, the tape is fixed in the cutting zone by creating a vacuum under it.
