Abstract
A gripper arm includes jaw members (24,26) between which articles are engaged and from which engaged articles are released in precise placement upon a transport means. Jaw (26) is actuated by solenoid actuating means (28) acting through linkage means (30) to perform the engagement and release operations. The activation of the solenoid actuating means (28) is controlled to be dependent upon the operating speed of a machine in conjunction with which the gripper arm is used. The solenoid actuating means (28) is assisted by biasing means (122) which is preloaded to facilitate the application of a desired holding force on articles engaged between the jaw members (24,26). The jaw member (24) has a piece (162) of high coefficient of friction material embedded in a surface oriented to contact articles engaged between the jaws (24, 26).
