SWITCH SHEET MANUFACTURING METHOD AND APPARATUS

WIPO Patent Application WO/1996/011794

A1

This invention relates to a method of manufacturing a switch sheet, a constituent part of a touch sensitive switch, and an apparatus therefor. According to the present invention, a trash removing tape (7) is pasted on a lower surface of a film separator (4) so that an adhesive surface of the former is fixed closely on the latter, and a first hole is formed in the film separator (4) by a first punch (14). A processing tape (5) is then pasted on an upper surface of the resultant film separator (4) so that an adhesive surface of the former is fixed closely on the latter. This processing tape (5) is then punched to a set shape by a second punch (15), and a second hole is formed at the same time through the processing tape (5), film separator (4) and trash removing tape (7). When the film separator (4) and trash removing tape (7) with the processing tape of a set shape pasted on the film separator are drawn out, the punched processing tape (5) is separated by taking up the same, whereby the above-mentioned switch sheet is manufactured. Thus, the switch sheet can be manufactured automatically.
