Abstract

909,101. Wrapping-machines. VAN BUREN MACHINE CORPORATION. April 29, 1959, No. 14625/59. Class 94(1). A machine applies inner and outer wrappers simultaneously to an article such as a bar of soap, the inner wrapper B being in the form of a carton blank with end closing flaps 45-48, the wrappers being juxtaposed by the machine before application to the article. The outer wrapper W is cut from a web S and fed between rolls 38, 39 to rest on a stop 55. The blank B is also fed between rolls 38, 39. A heater 35, in one embodiment, activates a wax coating beneath a porous surface of the wrapper so that blank and wrapper adhere to each other as they pass between the rolls. In an alternative form of locating apparatus, Fig. 9 (not shown) a pair of horizontally reciprocating pins 100, 101 engage beneath the flaps 45, 46 to support the blank relative to the wrapper in the position shown in Fig. 10, A plunger 21 forces the article C and wrapper between plates 22, 23 in a rotatable folding box, members, Fig. 2 (not shown) forming and tucks and folding in flaps 45, 46. The box rotates through 90 degrees and an ejector 62 thrusts the article and wrappers into a folding channel 72, a member 70 and the side 74 of the channel completing the tubular formation of the wrappers and a heater 73 sealing the overlap. Folders 81, 82, 90 complete the end folds. The part 75 of the wall 74 is cooled to consolidate the overlap seam. The package is then ejected past end sealing and cooling plates 115, 116. Specification 901,471 is referred to.
