Abstract

889,202. Endless conveyers. KOLB, O. K. (Haloid Co.). June 5, 1958, No. 18009/58. Class 78 (1). [Also in Group XX] In a xerographic printing apparatus (see Group XX) a powder 24 containing ferromagnetic particles is carried into contact with a relatively moving drum 10 by a magnetic conveyer having an endless magnetic belt 21 and an endless non-magnetic belt 18. Container 25 is agitated by solenoid 28 so that powder 24 is kept well mixed and in contact with non-magnetic belt 18 having transverse slats 20 of wood, metal or plastic which project at either side of the cloth or plastic web of the belt and rub against flanges 11 of the drum 10. The cloth or plastic web of belt 21 projects at either end of trough-shaped permanent magnets 23 which are attached to it and runs on flanges 14 of driven rollers 13. Roller 27 is also driven and the belt 18 returns the ferro-magnetic particles to the container 25.
