ABSTRACT:
An insertion machine has a plurality of gripper arms (16), each gripper arm including jaw members (24,26) between which inserts are engaged and from which engaged inserts are released in precise placement upon a transport means (18). Each jaw (26) is actuated by actuating means (28) acting through linkage means (30) to perform the engagement and release operations. Upon insert engagement the activation of the actuating means (28) is controlled to be dependent upon the operating speed of the insertion machine. Upon insert release the activation of each actuating means (28) is controlled so that release is delayed by three release time delay components. A first release time delay component is occasioned by a master presettable release delay means (322) which delays the release operation actuating means (28) of all insert stations in accordance with a preset input value. A second release time delay component is dependent upon the operating speed of the insertion machine. A third release time delay component, which varies from insert station to insert station depending on insert size, is occasioned by individual station presettable release delay means (338) which delays the release operation of actuating means (28) for its insert station.
