Title: Improvements in and relating to wrapping machines
IPC: B65B11/22
Filed: 1934-12-17
Abstract: 436,487. Wrapping-machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Dec. 17, 1934, No. 36189. Convention date, May 5. [Class 94 (i)] A machine for wrapping loaves &c., of the kind in which a loaf with a superposed wrapper is raised vertically with respect to folding devices and is then moved horizontally with respect to further folding devices is adapted for manual operation, the vertical and horizontal movements being independently controlled. The loaves to be wrapped are placed on a table 176, Fig. 6, and are advanced by the operator until the leading loaf is on the lifting platform 99, 100 which is raised by means of a treadle 82 and held by the engagement of a latch 111, Fig. 4, on an arm 110 with a notch 112 in the lifter bar 90. Waxed paper or other wrapping material is fed from a reel R, Fig. 1, between feed rollers 151, 152 on to wires 159, Fig. 5, stretched between bars 158, 175. A handle 138 when depressed rocks a toothed segment 145 in mesh with a gear-wheel 146 which drives the feed rollers through a oneway clutch. The feed rollers 152 may be lifted when it is desired to introduce a fresh web. Raising of the handle 138 rocks an arm 166 on a shaft 129 to sever a wrapper length from the web by means of a knife 168. The leading end of the severed wrapper W is drawn manually over the bar 175 and placed on a plate 36. As the loaf is raised, the wrapper is draped about three sides of it, while tuckers 44 fold the top flaps against the ends, as in Fig. 7. A tension plate 177 holds the wrapper against the top of the loaf. The operator now pushes the handle 34 to move a plate 37 inwardly beneath the loaf, and a cam 122 acts on a roller 124 so as to withdraw the arm 105 slightly, allowing the lifter bar 90 to drop, as in Fig. 9, until the latch 111 engages a notch 113. The continued advance of the plate 37 completes the bottom fold, as in Fig. 10, and a second cam 123 acts on the roller 124 so as to allow the lifter bar 90 to drop to its original position, Folders 40, Fig. 11, carried by the plate 37 fold in the side flaps of the wrapper. The advance of the plate 37 is stopped when collars 117 on slide bars 28, 29 meet lugs 118, and further operation of the handle 34 results in sliding movement of a pusher plate 38 relatively to the bars 28, 29 against the action of springs 119. The loaf is thus moved on to the table 67, Fig. 13, the edge of which folds the hanging end of the wrapper beneath the loaf, and by cam action the folders 44 are swung out of position. The loaf is advanced from position A<1> to position A<11> when the next loaf arrives on the table 67, and the bottom flaps are folded against the ends by entering guide slots 57 in plates 56a. The wrapped loaves are advanced step by step between heat-sealing plates 60 and cooling plates 64 to a delivery table 73. The folding members 40, 44, 56a, as well as the side plates 60, 64 are adjustable to deal with packages of different sizes.
