Abstract

A slider assembly for the actuator of a print system is shown in the figures. Referring to Fig. 1, the slider assembly 1 is manufactured by pre-forming magnetically permeable bars 2, such as by cutting them from continuous wire. The pre-formed magnetic bars are then held in position by a temporary clamp to permit a strand of non-magnetic high strength wire 3 to be looped around the magnetic bars. The wire 3 and magnetic bars 2 are attached at points of contact 4 by spot-welding or other suitable means. This wire and magnetic bar unit 5 is then inserted into a slider mold 6 and held in place by locating pins 7. Molding material is then injected to form the slider. (Image Omitted) The slider assembly 1 can be employed in a print system, such as shown in Fig. 2.

Slider Assembly for Better Magnetic Properties and Higher Mechanical Strength

A slider assembly for the actuator of a print system is shown in the figures. Referring to Fig. 1, the slider assembly 1 is manufactured by pre-forming magnetically permeable bars 2, such as by cutting them from continuous wire. The pre-formed magnetic bars are then held in position by a temporary clamp to permit a strand of non-magnetic high strength wire 3 to be looped around the magnetic bars. The wire 3 and magnetic bars 2 are attached at points of contact 4 by spot-welding or other suitable means. This wire and magnetic bar unit 5 is then inserted into a slider mold 6 and held in place by locating pins 7. Molding material is then injected to form the slider.

The slider assembly 1 can be employed in a print system, such as shown in Fig.
2. The slider assembly 1 is located between a dual coil/stator assembly 12 and is free to translate left to right. The slider is connected to a print hammer actuating lever 13. By applying electric current to the coils of the stator, the magnetic bars 2 of the slider are drawn into alignment with the magnetic poles of the stator, as shown by the arrow A, moving the slider, actuating lever and print hammer 14 toward the paper and print band to imprint the desired character.
