Apparatus for mounting finger for transfer feeder
 This invention relates to an apparatus for mounting fingers for transfer bars for use in a transfer feeder wherein each of the fingers serving as workpiece gripping means can be moved without causing any interference of the finger with an adjoining finger or upright. This apparatus comprises moving plates located on end bars arranged, respectively, behind the left and right uprights on the front side of the press body and which are each connected to a two-stage tandem cylinder mounted on each of the central bars adapted to be taken out of the press body together with the moving bolster so that the moving plates may be moved freely in the longitudinal direction of the transfer bars which are dividable into a plurality of segments by means of the cylinder, and fingers mounted on the moving plates. Each of the fingers has a misgrip detector. Further, transmission couplers and access switches are provided to transmit a signal generated by the misgrip detector in non-contact state.
