ABSTRACT:
Magnetically actuated impact equipment useful for high speed printers, punches or the like, is disclosed. Actuating magnets formed of materials characterized by wide hysteresis loops such as samarium-cobalt and mischmetal cobalt are disclosed. As disclosed, these magnets are oriented with like poles facing one another along opposite sides of gaps which run lengthwise of a print line. Magnetically actuated devices are shown with coils extending into the gaps with the plane of each coil being parallel to the print line. In one embodiment of the invention the magnets are arranged in upper and lower banks with coils on different movable devices extending upwardly and downwardly into gaps between the magnets in each bank. Another embodiment discloses coil-carrying devices which are mounted so as to be stepped along the gaps to various printing positions.
