  • Patent number: 6206006
    Abstract: Hand filling device for cigarette tubes, particularly for filter cigarette tubes, with a tobacco press chamber extending in the longitudinal direction thereof, which is formed by a casing (12) located in the base portion (14), a press head (16) provided on a lid (18) covering the casing (12) and hinged to the casing (12), an ejector slide (22) for ejecting a tobacco skein pressed in a tobacco chamber via an opening (24) provided in the casing (12) into a (filter) cigarette tube, of a clamp device (59), which holds the (filter) cigarette tube in a clamping manner on a socket (50) located at the outlet of the tobacco press chamber, and of a resiliently-engaging, snap-in or the like device (60) for detachable connection of casing (12) and lid (18).

  • Patent number: 5526825
    Abstract: Smoking tobacco is provided for self-making finished cigarettes. A tobacco unit (47) includes a plurality of sub-quantity portions (48 or 50, respectively) which are held together by inner and/or outer fixing means (49) to form a stack of separable portions. Each quantity portion (48 or 50) contains substantially the tobacco quantity required for a finished cigarette. The outer surface of the tobacco unit (47) and/or the sub-quantity portions (48 or 50) are all permeable to air such that the tobacco unit or each portion is not drawable as such and hence cannot be smoked. The tobacco portions of unit (47) are each configured like a rod and interconnected by paste to form a rod belt (51), or are configured as a flat oval tobacco unit comprising the plurality of sub-quantity portions (48) as a continuous mass.

  • Patent number: 4658837
    Abstract: In a manual apparatus for tamping cigarette tubes with tobacco, comprising a casing having a tobacco compressing chamber disposed in the longitudinal direction thereof, a cover-type press bar associated with this tobacco compressing chamber and located in a cover that covers the casing and being swingable about an axis, as well as an ejector slide, which is connected with a spoon 25 that carries a plug of tobacco, for introducing the pressed tobacco plug into a cigarette tube intermittently clampingly held against a short socket, a clamping element embodied such as to separate the clamping operation from the filling operation is provided. The clamping element (14) for a cigarette tube (4) mounted on the short socket (3) is independent of the cover (6) and is controlled by the ejector slide (7). It is spring loaded and disposed laterally beside the short socket (3).

  • Patent number: 4620551
    Abstract: In an apparatus for filling cigarette tubes in particular filter cigarette tubes, comprising a casing having a tobacco compressing chamber disposed in the longitudinal direction thereof, a coverlike press bar associated with this tobacco compressing chamber and located in a cover, that covers the casing housing and hinged on a shaft, as well as an ejector pusher for introducing a pressed plug of cut tobacco into a cigarette tube, that is intermittently retained by clamping on a short socket, the clamping device is intended to be embodied such that the clamping operation is completely divided from the filling operation, wherein the functional reliability of the individual elements of the filling apparatus is increased without making the apparatus less convenient to use.

  • Patent number: 4249546
    Abstract: An apparatus for filling empty cigarette blanks in which tobacco is placed in a tobacco magazine. When an operating lever is actuated, a pressure plate compresses the tobacco into a column. Upon further actuation of the lever, an elastic rack expels these columns so formed through a boss on which the cigarette blank is held by pincers. In order to adapt the apparatus to cigarette blanks of various lengths, in particular to cigarette blanks having single or dual filters, there is provided a movable slide which limits the amount of tobacco placed in the tobacco magazine to correspond to the amount required by a particular cigarette blank.

  • Patent number: 4167091
    Abstract: A chute filling device for handling cigarette filter tubes has a funnel and a chute divided by partitions, as well as a discharge opening and a pushing arm, wherein the partitions are loosely suspended with play in slots in a swing frame, the partitions being capable of being set to oscillating in such manner that the cigarette filter tubes are braked as they fall by frequent contact with the chute walls and move downwardly while maintaining their horizontal attitude.
