Abstract: 414,492. Wrapping and packeting machines. BUREN, J. VAN, 750, Grand Street, Brooklyn, New York, U.S.A. June 7, 1933, No. 16374. [Classes 18 and 94 (i).] Articles such as cakes of soap are wrapped in paper wrappers and enclosed singly or otherwise in boxes or cartons formed by folding blanks into tubular open ended containers, and closing the ends. Wrapping. The articles are fed into the machine over a table 69, Fig. 25, by a chain 65, and the left hand one is raised by a plunger 91 to a position between horizontally movable members 100, 101. Meanwhile, a wrapper has been fed from the bottom of a pile in a magazine H by an arcuate lug 50 of rubber &c. on a roll 51 between rolls 54, 55, and is disposed in the path of the article so that, when the member 100 moves to the left, it pushes the article, with the wrapper partly applied to it, into a pocket P<1>, of which the member 101 forms the movable base. The pockets P<1>, P<2> are formed with resilient walls 117 and are mounted for oscillation between a horizontal position, as shown in Fig. 25, and a vertical position as shown in Fig. 30, in which the mouths of the pockets are in opposed relation. After turning to the latter position, the wrapper W has been applied, by the walls of the pocket, to three sides of the article and a flap W<1> is left projecting. A lever 126, Fig. 25, is now actuated to feed the article and wrapper into the upper pocket P<2>, the flap W<1> being folded in to surround the article with an openended tubular wrapper formation. The base 120 of the pocket P<2>, which is frictionally held in position by a sliding rod 101, recedes as the article enters the pocket. The pockets swing back into horizontal positions again, and crimping members 135, 136, Fig. 29, turn in the ends of the wrapper and press them against the sides of the article, the action being assisted by spring members 142, 143 which press the wrapper against the ends of the article. The wrapped article is now ready for insertion into a carton. Forming cartons. The carton blanks, which are of the form shown in Fig. 16, are fed from a hopper J, Fig. 6, by a feed member 175 and rolls 185, 187, through a guide 196 and on to a hollow rectangular support 199. Adhesive is applied to the flap C by a roll 191. The panels E, K, K<1> of the blank coincide with the top surface 198 of the support 199. The blank is fed along the support by feed rolls 208, Figs. 3 and 8, co-operating with rolls engaging the panels F, G of the blank. Rotating blades 211, 212 fold down the panels C, D. At a subsequent stage, Fig. 9, feed rolls 215 engage the panel E, while the panels F, G are folded down by blades 217, 218 and finally the originally folded parts C, D are turned up against the underside of the support by folding blades 220, 221. The carton blank has now been formed into a complete tube about the support and members 225, 226 exert pressure in order to secure adhesion. The leading flap K<1> of the carton is raised from the support, and a reciprocating arm 250 moves to its right-hand position, Fig. 21, in which a lug has turned the flap back so that it can be engaged by a lug 266 for feeding the carton to the left on the return stroke. The carton is now over a portion of the support which is open at the side, and a wrapped article has been ejected from the upper pocket through the open side so that the carton when moved to the left by the arm, embraces the article. A plunger 270, Fig. 6, feeds the article, at the same time as the carton, and within it, on to a table 290, Fig. 3. The table rises to the level of a table 300, Fig. 34, along which the carton is moved by a transporter bar 301 having tabs 305 which turn in the tabs N, N<1> of the carton. The tabs R, R<1> are turned down by the ends of receiving walls 308. The flaps K, K<1> are initially turned down by guide flanges 319 and subsequently by the successive action of rollers 325-329. The extension flaps are guided into the openings in the ends of the cartons by cam strips. The cartons are moved by the succeeding ones until they arrive upon a conveyer which takes them out of the machine. The Specification also describes a modified machine for wrapping and boxing two articles in one carton.
