Abstract

Shown above is a guide fixture 10, a magnetic brush core 12 and a flexible magnet 14 that mounts on the magnetic brush core. The magnet 14 is C-shaped with an inner diameter slightly less than the outer diameter of the core 12. Guide key 16 and spreader 18 are used to guide permanent flexible magnet 14 over core 12. After the magnet has been slipped onto the core, the combined core and magnet assembly are removed from the fixture 10. The magnet may then be magnetized with the desired pattern for the copier magnetic brush.

Assembling Permanent Flexible Magnet on Copier Magnetic Brush. November 1982

Shown above is a guide fixture 10, a magnetic brush core 12 and a flexible magnet 14 that mounts on the magnetic brush core. The magnet 14 is C-shaped with an inner diameter slightly less than the outer diameter of the core 12. Guide key 16 and spreader 18 are used to guide permanent flexible magnet 14 over core 12. After the magnet has been slipped onto the core, the combined core and magnet assembly are removed from the fixture 10. The magnet may then be magnetized with the desired pattern for the copier magnetic brush.

The method of assembly includes the following steps. Core 12 of the magnetic brush is positioned on top of key 16 behind spreader 18. The permanent flexible magnet 14 is then positioned in front of the spreader so that it may be rammed forward onto the core 12. Magnet 14 is aligned so that the open section of the C aligns with the key 16. As the magnet 14 is pushed forward, key 16 and spreader 18 flexes the magnet 14 to a slightly larger inside diameter. Magnet 14 slips over the core 12 as it is pushed forward into the key and spreader 18.

Once the magnet 14 is positioned on the core 12, the assembled magnetic brush is removed from the fixture 10. The magnetic brush is placed in a magnetizing fixture (not shown) which will orient the magnetization in the permanent flexible magnet 14 mounted on core 12. The pattern depends upon the function of the magnetic brush in the c...
