Filed: 1954-11-26
Abstract: <PICT:0758317/IV(a)/1> <PICT:0758317/IV(a)/2> <PICT:0758317/IV(a)/3> In apparatus for casting films from a spreader box on to a rotating drum, the material passes from a receptacle to the spreader box, which has an adjustable slit orifice, via a flexible tube, the cross-section of the tube being adjusted by a float mechanism so as to maintain a constant level of material in the spreader box, whereby films of more uniform thickness are produced.  The invention is described in relation to the production of gelatine films suitable for making capsules.  As shown in Fig. 1, the gelatine is maintained at a suitable temperature in receptacle 12 by a heating element 36 and passes via stop-cock 14 and flexible tube 73 to the spreader box 16.  The spreader box rests on the rotating drum 18 at its slit orifice 56 and legs 50 and is anchored by a pair of bars 53 pivoted to the machine frame at 55.  The drum is driven by pinion 30 and may be internally cooled by a refrigerant.  The solidified film 20 is removed from the drum by driven roller 38.  The float mechanism for controlling the aperture of flexible tube 73 is shown in cross-section in Fig. 2 and in plan (enlarged) in Fig. 4.  The tube 73 is constricted between a pair of members 80, 91, the member 80 being fixedly supported from the machine frame by parallel guide bars 78, 79 and the member 91 forming part of a movable assembly comprising parallel bars 82, 83 and cross-member 86 which assembly is slidably mounted on the guide bars 78, 79. Movement of the assembly is controlled by float 74 attached to arm 75 pivoted at 76 and having a finger 90 which engages cross-member 86 so that as the level of gelatine in the spreader box rises finger 90 moves the assembly carrying member 91 to restrict the flow of gelatine through tube 73. The position of member 91 on the movable assembly may be adjusted by knurled nuts 94, 95.  The thickness of film may be varied by raising or lowering the doctor plate 47 by means of knurled nuts 66, 67, the doctor plate then being clamped in position by fixingscrews 62, 63, 64, 65.
