Two methods are disclosed for forming wire bundles, one method for forming an elongated wire bundle longer than the conventional working table and a second method for forming a shorter wire bundle. An apparatus for carrying out both methods comprises an endless canvas belt stretched between two rollers mounted at the ends of an elongated table, a drawing on rollers at each end of the table and overlying and supported by the belt for moving therewith, and a plurality of wires from reels at one end of the table for being positioned over the drawing and held in precise position with detachable brackets during the forming of the wire bundle. Then after completion of the wire bundle, or portion thereof, the endless belt is started moving and as the completed wire bundle winds on to a storage reel, the brackets are released by a trigger device to permit the drawing to separate from the endless belt and wind up on a storage roller. For carrying out the former method, as the first portion of the drawing for which the wire bundle has been completely assembled, is wound on the storage roller, it pulls the second portion of the drawing and the wire related to that portion out over the table for being clamped to the endless belt so that the rest of the bundle may be formed thereover. This continuous forming and storing of the wire bundle portions is carried on until all of the elongated wire bundle is coiled on its storage reel before the next wire bundle is begun. For carrying out the latter method, as a complete wire bundle is formed over the drawing, the finished wire bundle is disconnected from the drawing and the endless belt, and wound on the storage reel as the drawing is wound on its storage roller. Then the drawing is reversed and rewound back on the table for permitting the forming of another wire bundle like the first. For ease of working on the wire bundles by human beings working over the drawing, the portion including the drawing and its rollers, the supporting endless belt and its rollers, the clamping brackets attaching all together, and the wires extending over the drawing may be tilted to a convenient angle. A quick opening bracket with a plurality of clamps thereon is disclosed which opens instantly upon contact with a trigger device at the end of the work table.
This application is a continuation of a copending application Ser. No. 55,502, filed July 16, 1970, now abandoned.
