  • Patent number: 9352859
    Abstract: A device for feeding charges of non-homogeneous infusion material to a packaging machine includes a metering device for the charges and transfer system for the charges which is positioned downstream of the metering device and which feeds the charges to the packaging machine. The transfer system includes a charge adjustment system equipped with a drum which is rotatable about its own axis A and at least one roller which is rotatable about its own axis B and which is located upstream of the drum. The drum includes a chamber for receiving the charge from the roller. During adjustment of the charge, the chamber is variable between a maximum value coinciding with the receiving step and a minimum value when the charge has been adjusted.

  • Patent number: 8985642
    Abstract: A method for applying a component of a package for a substance for infusion having a filter bag for containing a substance and a pickup tag for manually picking up the filter bag includes a method for knotting a string to at least one of the components, which has the steps of interposing, between a string which is held taut along a first axis and a needle having an open lateral eye and angled transversally to the axis of the string, at least one of the components of the package, the component being angled so that the plane in which it lies is substantially parallel with the axis of the string; hooking the string with a single needle and using a sequence of passes through the plane in which the component lies forming stitching, which knots at least two loops of the string that are linked together one after another; and tightening the stitching to stably knot the string to the one or each component of the package.

  • Patent number: 7434374
    Abstract: A method and a line for the high-speed packaging of filter bags (1) containing an infusion product comprises at least three successive operating steps whereby: the filter bags (1) are wrapped in a continuous protective tubular envelope (2) by sealing a continuous V-shaped folded strip (3) along a longitudinal sealing line (5) and transversal sealing lines (6); the tubular envelope (2) is cut into lengths; and the filter bags (1), individually wrapped in respective envelopes (2), are placed in cartons. In the method and line (26) according to the invention, the transversal seal (6) is made in two successive steps as the continuous folded strip (3) moves through two separate consecutive sealing stations (7, 8), the first station (7) making a part of the transversal seal (6) and the second station (8) completing the same transversal seal (6).

  • Patent number: 6871475
    Abstract: In a machine for making filter bags for infusion products, a flattened tube (34) is used which is made from a web (17) of filter paper that: is heat-sealable by thermal reactivation of a layer of glue; is fed continuously in the horizontal position; has individual charges (19) of the infusion product placed on its top surface at suitable intervals; and, lastly, is gradually folded onto itself until its longitudinal edges (18) are juxtaposed. An apparatus (250) for sealing the tube (34) comprises an operator block (94) bearing two rows (251) of emitters (96) designed to give off a gaseous fluid heated to a suitable temperature. The operator block (94), accommodated inside the tube (34) with the emitters (96) aligned and juxtaposed with the edges (18), directs the fluid against internal faces (97) of the tube (34) directly at the layer of glue on the web (17) which is simultaneously folded around the operator block (94) itself.

  • Patent number: 6122894
    Abstract: An apparatus for making a wrapper for a product comprises: a feed device; an area for unwinding a web of heat-sealable paper; a station for feeding products which continuously receives and feeds out a first web of paper while placing the products on the web in succession and spaced equally apart; a station for feeding a second web of heat-sealable paper, where the second web of paper, fed by the feed device, is laid over the products and moves along continuously together with the first web of paper below it; a sealing station where the two webs of paper are joined crossways and lengthways to form a chain of closed wrappers, each containing a product. The apparatus comprises a single pair of feed rollers equipped with sealing elements and means for automatically detecting and correcting the misalignment of the sealing elements relative to the webs of paper by causing the rollers and the webs of paper to slip relative to each other.

  • Patent number: 6102189
    Abstract: A device for positioning products in succession and equally spaced on a conveyor belt comprises: a first rotor which rotates about a fixed horizontal axis of rotation, with a radial pusher which, when the first rotor rotates, intercepts the back of a product, accelerating it along a feed line towards the conveyor belt; and a second rotor which rotates about a fixed axis of rotation parallel with the axis of the first rotor and has a stop which, when the second rotor rotates, periodically intercepts the product feed line. The second rotor is located above the conveyor belt and rotates in such a way that, when it intercepts the feed line, it causes the stop to rotate at a peripheral speed identical to the belt feed speed. The stop on the second rotor intercepts the products accelerated by the first rotor, slowing them and depositing them on the belt in succession and spaced equally apart.

  • Patent number: 6041578
    Abstract: The invention relates to a device for a packaging machine to form groups of products and insert them into cartons at a cartoning station. The device comprises a stacking line equipped with a controlled outfeed hopper in which an alternating product presser operates. The stacking line comprises a container located at the bottom of the hopper and having a tongue inside it designed to retain the products forming the group which thus grows downwards towards an endwall of the container. The container moves alternately from a position in which it is connected with the hopper to a position in which it is connected with the cartoning station where the group is extracted from the container and transferred to the carton. The tongue is actuated by linear actuating means synchronized with the packaging machine by programmable control means and providing the enable signal to cut off the hopper to allow the container to move to the cartoning station.
