Abstract: Embodiments include a method or a device for a cartoning machine for transferring a leaflet from a first transportation device to a leaflet holder in a second transportation device. Embodiments include a transferring device which is arranged to straighten up and position the leaflets in such a way that the leaflet holders can take hold of the leaflets. The transferring device has a base surface with one or more carriers placed in a line at right angels to the direction of transportation, so that the leaflet, as a result of being able to slide against the base surface, is pressed back against the carriers as a result of air resistance friction against an adjacent cover plate and/or centripetal forces. The base surface of the transferring device is preferably provided with several lines of carriers which are adjusted to match the distance between the leaflet holders on the second transportation device.

Abstract: The invention provides tube-filling machines and methods for, in such machines, end sealing of double tubes (10), that is to say the tube type which has concentric packing tubes (11, 12) which are connected to a common tube shoulder (13) provided with a dispensing opening. The invention provides a two-part hot-gas nozzle (22) with individual supply of hot gas to the inner side of the inner tube and the outer tube for thermal activation of the scaling end of the double tube intended for heat sealing.

Abstract: Methods for filing tubes having inner and outer tubes separated by a predetermined gap are provided including delivering the tube to a tube filling station, filling the predetermined gap at the tube filling station by centering the outer tube with respect to an elongated nozzle including a plurality of filling pipes corresponding to the predetermined gap and a mandrel for insertion into the inner tube by means of a centering sleeve disposed externally around the elongated nozzle to provide the outer tube with a nominal cross sectional shape and centering the inner tube with respect to the elongated nozzle by means of the mandrel disposed within the inner tube to provide the inner tube with its nominal cross sectional shape, positioning the elongated nozzle proximate to a common tube shoulder at the first end of the tube connecting the inner tube to the outer tube, filling the predetermined gap with the plurality of filling tubes while guiding the elongated nozzle out of the second end of the tube while retain

Abstract: The invention relates to a synchronizing method and transfer arrangement for synchronizing the patterns of movement between two units included in a packaging line, where one unit is driven intermittently and the other continuously. The invention relates in particular to a transfer arrangement between an intermittently operating tube filler and a continuously operating cartoning machine. The transfer arrangement has a frame arrangement (13) intended to support tube pickers/placers (28) and arranged for a pivoting movement about a horizontal axis (16) and for a turning movement about a vertical axis (17). The turning movement about the axis (17) gives an acceleration course for the frame in a position in front of the tube release station, and this turning movement generating acceleration is obtained by an axially acting cam guide (32). The latter is designed so that the tube pickers/placers in the release position are given the same speed as the case conveyor of the cartoning machine.

Abstract: The present invention relates to feeder assemblies, and more specifically, relates to feeder assemblies for a tube-filling machine. The present invention includes at least one robotic arm capable of moving tubes and tube holders between two locations. The robotic arm may also move the tubes and tube holders relative to one another in order that the distance between adjacent tubes is substantially equal to the holders which carry and house the tubes.

Abstract: A method and apparatus for the end closure of packaging tubes is provided. In one embodiment, the tube which is to be sealed presents an intermediate wall having a surplus length across the tube cross-section, and the intermediate wall is fixed at the filling end of the tube to the tube wall and along two joining locations extending along the length of the tube. A hot air nozzle with two sub-members forming a gap therebetween is inserted into the opening in the filling end, and parts of the intermediate wall and the inside of the tube intended for sealing are heat activated in a non-contacting manner. Apparatus for producing a clamping action is pressed against the heat activated tube end and the intermediate wall. This apparatus includes a pair of clamping jaws arranged for translatory motion perpendicular to the tube axis and initially in a direction at an angle to a line through the joining locations.

Abstract: The invention relates to a device for extending an intermediate wall arranged in a packaging tube's longitudinal direction with a surplus of material as measured between the attachment locations of the intermediate wall. Means arc provided for orientating the intermediate tube's attachment locations to predetermined positions and application means (13) is introduced on either side of the intermediate wall and has means (12c, 12d) for extending the intermediate wall. External welding jaws (15, 15a) are provided at the attachment locations and are arranged to attach the extended intermediate wall to the inside of the tube.

Abstract: Cutters are disclosed including a pair of cutting blade holders and a pair of cutting blades mounted for movement in a cutting direction with respect to each other, at least one of the blade holders comprising a sprung holder.

Abstract: Hot gas heating devices are disclosed for heating an end of a tubular body before it is heat sealed, including a nozzle casing having a nozzle cavity, a heating nozzle disposed within the nozzle cavity, whereby the heating nozzle can be mounted at a predetermined location within the end of the tubular body, the heating nozzle including a hot gas outlet for directing a hot gas in order that a predetermined region of the end of the tubular body can be heated, a hot gas exhaust for exhausting the hot gas from the end portion of the tubular body, the hot gas exhaust including an ejector for creating a substantially uniform pressure drop at the predetermined region of the end of the tubular body in order to create a uniform distribution of the hot gas on the predetermined region of the end of the tubular body, and a cooling and centering body disposed on the exterior of the end of the tubular body for cooling and centering the outer surface of the tubular body.
