Method and apparatus for feeding sheets to be applied to a wiring harness, sheet cutting apparatus and tape adhering apparatus

A method for assembling a wiring harness, comprising the steps of:

• providing a conveyor with a plurality of harness-assembling boards for assembling wiring harnesses, each said harness assembly board being associated with an index for identifying size data for at least one said sheet required for the wiring harness to be assembled on the harness-assembling board;
• conveying the harness assembly boards along the conveyer to each of a plurality of positions;
• assembling a plurality of wires and connectors on the harness-assembling boards at each of a plurality of said positions;
• providing at least one sheet feeding apparatus fixed at at least one fixed position along the conveyor;
• recognizing the index associated with the harness-assembling board aligned with the sheet feeding apparatus for identifying the size of at least one sheet necessary to assemble the wiring harness, and generating a recognition signal;
• dispensing at least one sheet of a specified size from a corresponding sheet roll in accordance with the recognition signal, and simultaneously applying an adhesive double coated tape provided with a separable strip to a side edge portion of the sheet;
• peeling off the separable strip from the double coated tape;
• cutting the sheet dispensed from the corresponding sheet roll to the specified size to form a sheet piece in accordance with the recognition signal;
• dropping the sheet piece gravitationally to a location on the harness assembly board in proximity to the respective wiring harness;
• and
• wrapping the sheet piece around a plurality of a wires at a selected location on the wiring harness.
