Abstract: The wire cutting, skinning and wrapping tool includes a hollow sleeve, a knife carried by the sleeve, a bit provided with a longitudinal groove which is able to slide in a forward and backward direction in the sleeve, the bit and the knife skinning an insulated wire over a predetermined length and a means to move the bit from a backward to a forward position during the skinning operation. The sleeve is provided by normally closed sleeve halves with the insulated wire opening the sleeve halves during the skinning operation and with the sleeve halves closing again when the bit is in the forward position after each skinning operation. The length of skinned wire is captured between the bit groove and the closed sleeve halves.

Abstract: The valve includes an input port and two output ports and an arrangement to cause fluid pulses to appear at the output ports as a result of the appearance of fluid pulses alternately at the inlet port. The fluid pulses fed to the inlet port directly appears at the outlet ports and directly causes the valve to pass at least through three successive positions for every two successive pulses at the inlet port. This valve controls the operation of a pneumatic control circuit of a wire cutting, skinning and wrapping tool which is mounted in the handgrip of the tool.
