Abstract: The closing of the end edges of the wrapper (5) which is wrapped around the product in a shape made tubular in a known manner, is performed by folders, some of which are dynamic (15, 15' and 17, 17' ), located in different stations, and some static (8, 8' and 18, 18'). The first pair of dynamic folders (15, 15}') is mounted on the same dynamic folder (14) that folds the first lateral edge (505) of the wrapper. A possible option is to replace the last pair of dynamic folders (17, 17') with a pair of static folders (25, 25'). Before the final rolling stage, the wrapped product passes through a shaped channel (19) that keeps the end folds of the wrapper correctly arranged. The last pair of static folders (18, 18') may be incorporated in this channel. The end edges of the wrapper may be folded in three or in four consecutive portions laid over each other.

Inward movement of a pair of folding blades creates additional top flaps on the sheet, which are then folded down by pivotal plates to complete the wrapping process.

Abstract: A method of overwrapping packets of cigarettes is implemented utilizing a machine by which packets and respective sheets of wrapping material are fed singly and in timed succession to a folding station where each packet is directed against a central portion of the corresponding sheet and advanced together with the sheet through a tubular duct of proportions such that the sheet is constrained to fold into a U formation around the packet. To optimize the folding action, the duct is fashioned with two longer side walls of convex profile by which the two lateral portions of the sheet flattened over the main lateral faces of the respective packet are engaged and compressed only along a limited central band of their full advancing width, and caused as a result to spread gradually into uniform contact with the overwrapped surfaces, without creasing.

Abstract: The present invention relates to a cartoning machine in which box-like (i.e., generally rectangular) contents with a carton positioned therearound are fed, and when the box-like contents with the carton have passed a pivotable face of a conveyance pocket positioned on the most upstream side in the conveyance direction, a fold-down piece operates to fold down an upper body flap of the carton. After this operation, the pivotable face is raised from a lower position to fold up a lower body flap, whereby the lower body flap is overlapped on the outside of the upper body flap to complete the body folding of the carton. Thereafter, a plurality of conveyance pockets are conveyed simultaneously by intermittent operation of endless flexible members, whereby side flaps of each carton, which has gone through the body flap folding operation, are folded in successively to complete the cartoning.

Abstract: The present invention comprises a device and method for feeding a cut loose-leaf material such as, for example tobacco, from a weight scale; dropping the tobacco into a hopper; compressing the tobacco into the desired size, shape, and density; and packaging the loose-leaf tobacco product. Packaging is accomplished by wrapping an inner foil and overwrap label around an arbor on a rotating arbor wheel. The package is constructed in various stages as the arbor wheel rotates to various positions. The inner foil is fed and wrapped around the arbor without extending the foil below the body of the package so that the foil does not form a bottom end. The foil extends above the body of the package and is folded to form a top end. An outer label having a sufficient length to extend past the top and bottom of the arbor is overwrapped about the foil innerwrap. The overwrap label extending past the bottom of the arbor is folded and glued over the foil innerwrap to form a top end to the package.

Abstract: A process and an apparatus for rejecting defective packages in the region of a packaging machine are disclosed. In the production of bundles formed from several individual packages, especially from a group (11) of cigarette packages (10), it is required to inspect the cigarette packages (10) as regards completeness of the group. Packages (13) which are thus found to be defective are marked in an exteriorly visible manner and are rejected at a later stage, especially in the region of a discharge track (26). The defective package (13) is marked by way of folding over a folding tab of an outer wrapping (12), especially a lower tab (33) in the region of a rearward side wall with respect to the conveying direction. The lower tab (33) forms a gusset (36) which is folded over to the outside.

Abstract: A package wrapping apparatus and method compresses a package of napkins or a similarly soft bulked product during the wrapping operation to provide a tight wrapped package which does not become loose with settling. An air activated expandable elevator plate allows the bottom of the napkin package to be completely supported during the wrapping operation, and contracts to allow the plate to be lowered between front and rear underfolders. This allows the napkin stack to undergo a greater degree of compression without defects, since folding or curling of the napkin edges over the elevator plate is avoided. An air activated movable top compression plate applies variable downloading against the top of the package. As the elevator plate is raised, the package presses against the top compression plate and is thereby compressed.

Abstract: The invention is a package including a bundle of shirred casing sticks disposed and held together by a container which completely encloses the bundle. The container is formed insitu about the bundle from a heat shrink film which stiffens on heat shrinking to provide a self-supporting container conforming in shape generally to the bundle shape. During heat shrinking, portions of the film are insulated to prevent welding of these portions so they provide flaps which open to permit removal or replacement of sticks.

Abstract: Apparatus (packaging machine) for the packaging of articles of differing size. In packaging technology, it is often necessary to solve the problem of producing packs of differing size on one and the same packaging machine. As a rule, adapting this to the different pack formats requires considerable conversion work. This in turn involves lengthy standstill phases of the packaging machine. To make it easier for the packaging machine to be changed over to different pack formats, packaging members, especially folding members, critical for the packaging process are provided in the form of a plurality of, preferably two sets (40, 41). A particular set of packaging members is in the packaging position (43). A further (part) set is in an exchange position (44) for the exchange of individual or all packaging members for other formats.

Abstract: Reams of paper advancing in a horizontal direction on a first belt are straightened initially by interaction with a transverse vertical barrier, while wrapping paper is drawn out from below the first belt and directed onto a third belt; the paper is pulled upright into the path of the ream by the elevation of a first gate affording a gap of height at least equal to that of the ream whereupon the ream is directed through the gap, becoming partially enveloped by the paper, then stopped on the third belt while the wrapping paper is cut near to the gate and the trailing edge simultaneously moistened with gum. Finally a second gate identical to the first is raised at the entry to the third belt, drawing up the remaining portion of the paper, and the conveying direction is reversed to take the ream back through the relative gap; the ream is thus enveloped completely and the gummed edge of the wrapping paper flattened and secured.
