Abstract: An apparatus (blank unit) for feeding blanks to an article to be wrapped is disclosed. In the feeding of blanks (13) or of a web of material (14) made from critical packaging materials (thin foils), suction conveyors (32 . . . 37) are used which transport, guide and retain the web of material (14). An optimum guidance of the web of material (14) is ensured when lateral elongated suction conveyors (32, 33) reach below a pack track (15). Additionally, shorter suction conveyors (34 . . . 37) are disposed above the pack track (15) in the region of the web of material (14). To adjust the blank unit to different widths of the web of material (14), the lateral elongated suction conveyors (32, 33) can be displaced transversely relative to one another. Moreover, individual shorter suction conveyors (34 . . . 37) can be removed.
Abstract: A method and apparatus for placing sleeves on bottles and other objects is disclosed. In particular, a high speed method and apparatus having a plurality of sleeving stations for placing sleeves on bottles is disclosed. Each sleeving station includes a circularly arranged set of relatively movable parallel pins which are operable to contract or expand. A label transporter deposits a sleeve on the pins when they are contracted. The pins expand to stretch the sleeve. A bottle and the pins are then moved relative to one another to place the bottle inside the stretched sleeve. A gas flow is provided between the bottle and the sleeve to reduce friction. The sleeved bottle is then stripped from the pins. The method occurs without starts and stops by the bottle or the sleeve and is thus capable of very high production rates.

An elongated perforated pipe is also positioned within the material in the bag and the bagging machine moves relative to the bag during the bagging operation. The presence of air in the channels created by the flutes and the air present in the perforated pipe ensures that sufficient air will be present in the mass to achieve complete decomposition of the material.
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.
