摘要： A machine for making filter bags of different shapes for infusion products includes: a wheel defining a work surface and rotating about a relative axis; feed stations for placing tags on the work surface, a continuous thread, along a weave path, and a strip of filter material superposing the weave of thread and the tag. A sealing device is located downstream of the feed stations for sealing between the thread, tag and strip of filter material. A feed device moving the strip along a feed line is positioned downstream of the wheel. A station introduces a dose of infusion product in bag and closes the bag. The feed device has two feed rollers, for unwinding the strip, controlled by a control system for adjusting the speed of rotation of the feed rollers as a function of the length of the filter material needed to form the bag.

摘要： A machine for forming bags with infusion or extraction products includes a station for forming and feeding single sheets; a U-shaped folding station for folding the sheet; a unit for sealing the two lateral edges the sheet to create a bag with a closed bottom and side and an open end opposite the bottom. A second carousel includes radial grippers each configured to receive a bag. A dosing station includes a first device for dosing a first product along a dosing trajectory towards the opening and a second dosing device for dosing a second product. A transporting element positioned between the dosing devices includes a container for receiving the second product. The transporting element moves the container from a second product dosing position to a position for unloading the second product coinciding with the dosing trajectory from where the container discharges the dose of the second product into the bag.

摘要： A dosing device for feeding an infusion product includes: a tower for containing loose infusion product, tubular channels for feeding and discharging the product, first containers for receiving the product from the channels; each channel actuated by an actuation device for releasing a quantity of product; a fixed platform supporting the first containers, a plurality of elements for weighing the product in the containers and supported by the platform; a control unit in communication with each actuating device and with each weighing element, to detect the value measured by each element and actuate the corresponding channel until reaching the quantity of product. Reference elements are independent of the weighing elements are associated with the platform each supporting a weight of predetermined value; each reference element is in communication with the control unit to transmit a signal equivalent to the measured value of the reference weight by the reference element.

摘要： A forming tube for making filter bags of tetrahedral shape for infusion products including a forming element, which is elongate and hollow, which defines a longitudinal axis and which has a first opening through which the product enters in the forming element, a second opening through which the product leaves from the forming element to be dosed inside a filter bag being formed, and an inner through cavity which connects the first opening to the second opening and inside of which flows the infusion product. The forming element includes a main body substantially tubular including the first opening and a forming end including the second opening and mobile in rotation with respect to the main body about the longitudinal axis.

摘要： An automatic machine includes a load-bearing frame having a base, a vertical side wall, a horizontal wall facing the base, a vertical front wall, defining a machine front with a protruding motor-driven shaft supporting a respective reel of wound material. A plurality of operating stations positioned on the front wall through which a processing path extends along which said material proceeds whilst it is unwound from the reel. A storage unit houses replacement reels is positioned directly associated with the frame close to the shaft. A device picks up reels and positions them on the shaft. The device is positioned directly associated with the frame close to the storage unit. A control unit activates the device in response to a run out signal of the reel present on the shaft.

摘要： A unit for over-wrapping filter bags includes a carousel rotating about a first axis with first and second grippers along a closed circular trajectory. A forming station for forming single sheets of over-wrapping material is arranged near the trajectory and includes a feeding device for feeding the sheets in a U-shape, synchronized with the first grippers. A first drum transports formed bags, rotates about a second axis and has grippers receiving the bags from a preceding station and releasing the bags from the first grippers with the U-shaped sheets in synchronization. A closing station includes a sealing gripper movable from a first position near the carousel, for picking the bag with the sheet the first gripper, to a second away position for closing the sheet and, lastly, to a third position near the carousel, for release of the enclosed bag to the second gripper.

摘要： A machine for making filter bags for infusion products includes a first carousel for continuous rotary movement about a first axis and having first operating stations movable therewith, each first operating station configured to operate on a corresponding piece of filter material fed along an angular stretch of the first carousel, to lift two chambers to a position side by side. A second carousel positioned alongside the first carousel and rotating continuously about a second axis parallel to the first axis has a plurality of joining elements positioned along, and continuously movable with, the second carousel. Each joining element is connected to corresponding control devices for actuating, in a synchronized fashion, a succession of movements of the joining element to intercept free ends of erect filter material, positioned on an operating station and joining them, towards one of the two chambers containing a dose of product.
