Abstract: A control system for controlling a plurality of automatic working apparatuses for performing different types of specified operations, respectively, so as to produce different types of, but functionally the same, work units for different types of products has a first data memory, provided for each of the working apparatuses, which controls each working apparatus independently from the other so as to perform a specified operation and a second data memory sharing a common memory area of the first data memory which stores operation data indicating types of operations of the respective working apparatuses and governs the first data memories so as to transfer the operation data to the first data memories therefrom all at once, whereby causing the working apparatuses to perform the different types of specified operations so as to complete a work unit.

Abstract: An apparatus for assembling a coil spring on a damper strut to manufacture a damper strut assembly. The apparatus includes a clamp for holding the strut in a vertical direction with the lower end of the spring attached to a lower spring seat provided on the strut. A caliper type spring depresser is provided. The depresser is mounted on a plate for movement along a substantially vertical guide rail mechanism. The plate is swingable in a substantially vertical plane so that the direction of movement of the depresser can be adjusted so as to coincide with the direction of the axis of the spring.
