Abstract: 922,898. Feeding webs. WALKER (ENFIELD) Ltd. Aug. 24, 1959 [May 22, 1958], No. 16461/58. Class 100 (1). A web splicing apparatus for joining a first strip of material to a second strip of material whilst a length of the latter continues to pass through a processing machine, comprises a strip-supporting surface 15 conversely curved in the longitudinal direction of the strips, a splicing head 24 adapted to perform, in conjunction with the supporting surface a splicing operation on the two strips, means for creating a reserve length of the second strip between the strip supporting surface and the machine, and means for feeding the reserve length to the processing machine while the two strips are maintained stationary during splicing. As shown, strip is drawn from a roll 12 carried by one arm 13 of a roll support pivoted at 14. The strip passes over the surface 15 having a lateral groove 16 housing a cutter bar 16a and flanges 11 to maintain the strips in correct alignment. Primary draw rollers 18 draw the strip around a roller 17, the top roller being raised by an hydraulic cylinder 23 prior to a splicing operation. The roller 17 is driven through a freewheel by an hydraulic motor 32. The strip forms a loop 19 between the rollers 18 and secondary draw rollers 22 of sufficient length to provide a sufficient length for supply to the machine during splicing. The splicing head 24 is rocked into operative position by an hydraulic cylinder 25 and is then caused to move transversely of the strips to cut both the strip from the roll 12 and a replacement strip from a roll 29 and apply adhesive tape to the join. The head 24 comprises a carriage 50 Fig. 2 (not shown) slidable on a cross-slide 51 and carrying a cutter wheel 52 and a tape ironing wheel 53 which draws adhesive tape from a roll 54. A roller 26 Fig. 1 is swung towards the strip by an hydraulic cylinder 28 to apply adhesive tape to the underside of the splice. The splicing apparatus is controlled by a timing device (not shown) which operates by means of electrical contacts actuated in the required sequence. In a modification Fig. 4 (not shown) the strip is formed into a series of loops by rolls 40 movable by an hydraulic ram 41. The rolls 12 and 29 are mounted in bearings attached to a pair of endless chains 33 driven by a motor 34.

Filed: 1959-05-13
Abstract: 846,855. Filters. KOMLINE-SANDERSON ENGINEERING CORPORATION. May 13, 1959, No. 16493/59. Class 46. The mixture to be filtered is delivered by a pipe 27, Fig. 1, to an open-bottomed hopper 28 having sealing engagement with the upper run 10a of an endless filter belt 10 which is driven intermittently by clockwise rotation of a roller 12 through actuation of a ratchet wheel 35 by pawls 36, 37. A cycle of operations is performed automatically by a motor 92 which drives continuously a wheel 88 having linked to it a segmental rack bar 85, Fig. 6. From the Fig. 6 position, the first movement leftwards of the rack bar serves to rotate a valve 60 which thereupon connects to atmosphere a header 62, Fig. 1, communicating by pipes 63 with a series of suction boxes 33 arranged on the underside of the upper run 10a of the belt. Valve 60 is left in this position, whilst the rack bar rotates a valve 78 which thereupon directs hydraulic fluid from a pump 55 to the upper end of a cylinder 72, Fig. 6, whereby through piston rod 74 a frame 68 sliding on bearings 69, Fig. 3, is moved downwards to the left and through links 70 moves a frame 65, carrying all the suction boxes, downwards vertically to the position of Fig. 3. The suction boxes are thus moved out of contact with the belt 10. Next, a valve 47 is rotated by the rack bar so as to cause fluid to be admitted to the lower ends of cylinders 42, 43, Fig. 1, and drained from the upper ends, to bring about movement of the belt 10, through actuation of ratchet wheel 35 by pawl 36 only, a distance equal to half that between suction box centres. The rack bar is now in the Fig. 1 position, and its first operation on the return movement is to restore valve 47, which reverses the fluid flows in cylinders 42, 43, and completes the movement of the belt 10 by ratchet 37. Then valve 78 is restored to effect the return of the suction boxes to contact with the belt 10, and finally valve 60 is restored to connect the suction boxes to vacuum and thus effect filtration. This continues until the rack bar rotates valve 60 once more on its next leftward movement and the cycle is repeated. Cake not falling from the belt at roller 12 is removed by a scraper 25.
