The operation of the arrangement of the invention is in a cyclic manner as described below during which valve 21 remains open.

[0011] At the beginning of a half cycle of operation of the arrangement, pinion 121 of the Geneva driver 117 is positioned at the mouth of slot 119a of the Geneva wheel 116 (Fig 15). During rotation of the Geneva driver in the anticlockwise direction pinion 121 travels away from slot 119a as shown in Figs 16 and 17 and no drive is transmitted to the Geneva wheel 116 and the solid cleanser feed conveyor 2, solid cleaner holder forming unit 31 comprising contrarotatable conveyors 32 and 33, film pulling units 100a, 100b, 100c and 100d, film scoring unit 84 and waste film carrying conveyor 98 remain stationary. Ports a and e and ports b and d of valves 20 of the film lamination units 11a and 11b are connected. Air flows into the piston side and air flows out into the atmosphere from the cylinder side of the cylinders 12. Pistons 15 of the cylinders 12 along with the movable laminator plates 23 move down towards the stationary laminator plates 27 of the film lamination units. Both the movable laminator plates 23 and stationary laminator plates 27 are being heated by the electric conductors 30 running therethrough. Both the films 156, 156 from top unwind rolls 5 positioned in the top lamination unit 11a are hot pressed together and laminated into a single top film along the lamination ridges 29 of the movable laminator plate 23 and stationary laminator plate 27 of the top lamination unit 11a. Similarly both the films 156, 156 from the bottom unwind rolls 6 positioned in the bottom lamination unit 11b are hot pressed together and laminated into single bottom film along the lamination ridges 29 of the movable laminator plate 23 and stationary laminator plate 27 of the bottom lamination unit 11b. The laminated top and bottom films emerging from the lamination units are marked 157. The films on the unwind rolls may be of the same or different materials, textures or colours as required. Ports b and d and ports a and e of valve 49 of the solid cleanser sealing unit 41 are connected. Air flows into the piston side and air flows out into the atmosphere from the cylinder side of the cylinder 42 of the solid cleanser sealing unit 41. The piston 45 of cylinder 42 along with the movable die plate 51 moves down towards the stationary die plate 55. Both the die sockets 57 in the movable die plate 51 and stationary die plate 55 are being heated by the electric conductors 58 running around them. The movable die plate 51 closes on the stationary die plate 55 and holds the solid cleanser holder positioned therebetween within the die sockets 57 and heat seals together the bottom and top films around the solid cleanser at the peripheries of the die sockets. Ports b and d and ports a and e of valve 67 of solid cleanser holder cutting unit are connected. Air flows into the piston side and air flows out into the atmosphere from the cylinder side of cylinder 60 of the solid cleanser holder cutting unit. The piston 63 of cylinder 60 along with the punch plate 69 moves down towards the stationary die plate 80. The punch plate 69 closes on the die plate 80 and holds the solid cleanser holder positioned therebetween within the die cavities and cuts the solid cleanser holder at the peripheries of the die cavities. On being cut and separated from the bottom and top films, the solid cleanser holder 160 falls down through the open bottom of the die cavity 82 in the die plate 80 and corresponding opening 83 in the base 81 of the supporting structure 62. While the punch plate 69 closes on the die plate 80 and cuts and separates the solid cleanser holder from the films, the retainer flange 78 presses against the films under spring tension and holds the films in position to facilitate cutting of the solid cleanser holders. The retainer flange slides in and out on the punch plate due to its being tensioned by springs 79 and fixed to the screw members 75 which are movably disposed in the holes 73. The outward movement of the screw members in holes 73 and hence that of the retainer flange is restricted by shoulders 77 as the heads of the screw members abuts the shoulders at the extreme outward position of the screw members. The size of the edges or frills of the solid cleanser holder from the sealing point thereof depends on the larger peripheries of the die cavities as compared to the die sockets. At the end of the half cycle of operation of the arrangement, the position of the pinion 121 of the Geneva driver 117 is as shown in Fig 17. The pinion 121 is about to enter slot 119f of the Geneva wheel 116. During further rotation of the Geneva driver in the anticlockwise direction the pinion 121 travels into the slot 119f of the Geneva wheel (Fig 18) and travels back from the slot 119f of the Geneva wheel and positions itself at the mouth of slot 119f of the Geneva wheel as shown in Fig 19. During this half cycle drive is transmitted to the Geneva wheel and it rotates in the clockwise direction. Consequently drive is transmitted to the solid cleanser feed conveyor 2, solid cleanser holder forming unit 31 comprising contrarotatable conveyors 32 and 33, film pulling units 100a, 100b, 100c and 100d and film scoring unit 84 and waste film carrying unit 98. Solid cleansers 158 being fed from the feed end of the conveyor 2 in the pockets formed by pairs of spaced upright members 4, are moved forward by the feed conveyor. Due to momentum of movement of the feed conveyor, the solid cleanser at the discharge end of the infeed conveyor is pushed by the advancing upright member 4 at the rear side of the solid cleanser 158 into the laminated bottom film 157 at the feed end 37a between the contmrotatable conveyors 32 and 33 over the flat protrusion 40. The contrarotating rollers of the film pulling units 100a and 100b pull the laminated bottom and top films from the lamination units 11a and 11b and keep them taut. In the solid cleanser holder forming unit 31, the bottom film 157 carrying the solid cleansers and the top film 157 overlying the solid cleansers form holders for the solid cleansers and are moved forward by and between the contrarotating conveyors 32 and 33. The bottom and top films having the solid cleansers interposed therebetween enter the solid cleanser holder staling unit 41. The contrarotating rollers of the film palling unit 100c pull the bottom and top films with the sealed solid cleansers holders emerging from the solid cleanser holder sealing unit and feed them to the solid cleanser cutting unit 59 one at a time. The contrarotating rollers of the film pulling unit 100d pull the bottom and top films from the solid cleanser cutting unit 59 through the film scoring unit 84 in which the rotary disc cutter 91 cuts or scores the waste films into two lengthwise, which remain as webs between adjacent cutouts of solid cleanser holders after they are cut and separated. The waste films emerging from the pulling unit 100d are carried onto the waste film carrying conveyor 98. The waste films are cut and removed from the waste film carrying conveyor as and when required.
Simultaneously ports b and c and ports a and d of valves 20 are connected. Air flows into the cylinder side and air flows out into the atmosphere from the piston side of the cylinders 12 of the film lamination units 11a and 11b. The piston 15 of the cylinders 12 move up into their original position. Ports b and c and ports a and d of valve 49 are connected. Air flows into the cylinder side and air flows out into the atmosphere from the piston side of cylinder 42 of the solid cleanser holder sealing unit 41. The piston 45 of cylinder 42 moves up to its original position. Ports b and c and ports a and d of value 67 are connected. Air flows into the cylinder side and air flows out into the atmosphere from the piston side of cylinder 60 of the solid cleanser holder cutting unit 59. The piston 63 of the cylinder 60 moves up to its original position. The arrangement is now ready for the next cycle of operation.

[0012] Due to the intermittent drive and feeding of solid cleansers into the solid cleaner holder forming unit in a cycle of operation of the arrangement a gap is maintained between two solid cleansers in the solid cleanser holder forming unit. The temperature controllers sense the temperatures of the laminator plates and movable die plate and corresponding stationary die plate through the thermostats and cut of the power supply when the temperatures exceed the set limits. The film tensioning rollers keep the films under tension. The bushes are to minimise friction between the guide plates and respective guide rods and render the up and down movement of the guide plates smooth.

[0013] The film lamination units, solid cleanser holder forming unit, solid cleanser holder sealing unit, solid cleanser holder cutting unit, film pulling units, film scoring unit and solid cleanser pockets may be of different constructions. There may be more than four film pulling units. Instead of pneumatic cylinders, hydraulic cylinders may be used. There may be more than two film unwind top rolls and more than two film unwind bottom rolls and corresponding number of films to be laminated. The waste film carrying conveyor and film scoring unit are optional. Instead of waste film carrying conveyor some other arrangement may be used to carry the used films. The sizes and profiles of the die sockets and die cavities will change depending upon the sizes and profiles of the solid cleansers and solid cleanser holders. The arrangement may include a solid cleanser feeding unit. Instead of film unwind rolls, the film feeding arrangement may be different. Such variations of the invention are to be construed and understood to be within the scope of the invention.
