The device for adjusting the lateral distance between a pair of parallel transfer bars of a transfer feeder for a transfer press comprises clutch means arranged in the driving means for driving toward and away a pair of slides slidably mounting thereon the transfer bars, respectively, so as to transfer work pieces to the succeeding working positions and separate driving means for driving the slides independently of the first mentioned driving means when the latter is disabled by the clutch means, so that the lateral distance is adjusted by driving the slides by the separate driving means while the first mentioned driving means is disabled. After disabling the separate driving means and the clutch means is engaged, the press is ready for operation with the newly adjusted lateral distance set between the slides and, hence, between the transfer bars. A set of limit switches are provided which cooperate with the driven member of the clutch means and operably connected to switching means of the clutch means and a clutch for the separate driving means so that the lateral distance between the slides can be automatically set by the actuation of the selected one of the limit switches which, when actuated by the driven member of the clutch means, actuates the switching means so as to engage the first mentioned clutch means while the clutch for the separate driving means is disabled after the clutch means has been disengaged and the slides have been driven by the separate driving means through the clutch.
