<p>PCT No. PCT/SE86/00133 Sec. 371 Date Jan. 27, 1987 Sec. 102(e) Date Jan. 27, 1987 PCT Filed Mar. 25, 1986 PCT Pub. No. WO86/05735 PCT Pub. Date Oct. 9, 1986.Indicator device for determining the distance between a workpiece set up in a working machine, and a tool set up in said machine. The device comprises a lower portion (2) with an underside (13) which is adapted to lie against the workpiece, and an upper portion (1) with a topside (8) against which the tool is intended to come into contact, the topside being parallel to the underside (13) of the lower portion and movable towards the underside against the efect of a resilient force. A voltage source (4) and an indicator (5) are provided. The underside (13) and the topside (8) are electrically conductive but are insulated from each other, and the indicator (5) and the voltage sorce (4) are electrically coupled so that the indicator (5) provides and indication when a circuit (16) between the topside (8) and the underside (13) is closed via the workpiece, the machine, the tool, the voltage source (4) and the indicator (5).</p> |
