Abstract

A press line system in which there is provided a series of individually driven presses arranged in a line and each having a work loading means and an unloader and in which each of said presses is fed with a workpiece by activation of its associated loading means. As the loading means returns to its initial position, a signal is generated for operating the press for a stroke of operation. After the stroke of operation has been completed, a further signal is generated for actuating the unloader associated with the press for discharging the work from the press. An intermittently driven conveyor is arranged between adjacent presses for conveying the work from the preceding press to the succeeding press, said conveyor being advanced in increments in response to a signal generated as the conveyor receives the work from said unloader associated with the preceding press until the work on said conveyor reaches a predetermined work feed position with respect to the succeeding press whereby the succeeding press can be operated in synchronization with the preceding press without being affected by the operation of the preceding press.
