Abstract: 1292453 Electrophotographic element CANON KK 5 Sept 1969 [6 Sept 1968] 44145/69 Heading H1K [Also in Division B2] A photosensitive member for electrophotography is made by moving an endless surface past a knife blade set at a predetermined distance from the surface, feeding wet photosensitive material to the gap to coat the surface and thereafter controlling the flow of material with the same or another blade so that the excess of material flows down the blade to be removed and leaves a uniform coating on the surface. In the embodiments a cylinder 1 or endless-belt is first coated 3 with a photoconductive dispersion 31 using a knife blade 2 and then the blade moved through an angle so that the excess of the dispersion is removed from the coating over the blade at 32. The blade may be repositioned adjacent either of the lower quadrants of the cylinder (Figs. 7 and 8, not shown). In alternative embodiments a vessel-type blade (6) may be used for the coating step and the excess of dispersion removed either using the vessel or a knife blade (Figs. 9 to 15, not shown). The distance of the blade from the cylinder surface may be predetermined by providing the cylinder edges with discs (9) which protrude beyond the cylinder (Figs. 18 and 19, not shown). In another embodiment the coating is built up on the inside of a hollow cylinder (Figs. 20-22, not shown). A coating of constant thickness may be obtained by finishing the cylinder on a lathe to a given circularity and then coating the cylinder on the lathe without removing it from its centres. The cylinder may be of A1, plastics, glass, paper, wood or ceramics and may be coated with Ag, AgO, carbon black or A1. The photoconductive layer may comprise ZnO, CdS, CdSe or an organic photoconductor dispersed in a binder such as a silicone resin, copoly vinyl chloride-acetate or an epoxy resin. An insulating layer may be provided between the cylinder and the photoconductive layer or on top of the layer.

The knife holder 5 is moved downwardly to shear sheet metal by a crank 3, the connecting rod 4 engaging in a bearing 12 in the holder 5. The knife holder is returned by means of the cylinder devices 20-22. Each cylinder 27 is slidably mounted in bearings 23, 24 on the housing and urged upwardly by springs 25 and a piston-rod 28 is also urged upwardly by means of fluid fed to the lower end of cylinder 27 during shearing operations. The cylinder devices also act as damping means. The hold down 40 is slidably mounted on a frame 41 which is pivoted at 42 to the housing 1 and during downward movement bears against stops 48 on the upper knife holder until the hold down contacts the workpiece. Hydraulic cylinder means (44- 46), Figs. 1 and 6 (not shown) are actuated continuously during shearing to maintain the hold down in workpiece-engaging position. Thrust applied longitudinally of the upper holder 5 due to variations in the workpiece thickness is borne by plates (55), Fig. 4, adjustable horizontally by hydraulic piston and cylinder units (59) on the housing 1 and engaged in a recess (56) in the holder 5. To change the knife assembly, the hold down 40 is prevented from vertical movement relative to the frame 41 by means of a lock (49) (Fig. 1) and the crank is notched to its lower dead centre position in which the holder 5 is not in contact with the hold down frame 41 which is pivoted by an hydraulic cylinder 43 out of the opening 11. The supply of fluid to cylinders 27 is cut off, discharge valves are opened gradually and the holder 5 moves down under its own weight below its lowest shearing position until it engages stops 100 on the lower knife holder 7. The rods 28 continue to move leaving a clearance Y2 between them and the holder 5. The cylinders 27 are urged upwardly by springs 25, leaving a clearance Y1.
