The present invention relates to a device for making a pouch received in a wrapping, comprising a pouch making device which is adapted to produce a pouch containing brewable material in a water-permeable wrapping, and comprising a sealing station with two sealing jaws movable relative to each other for sealing the pouch in a wrapping formed by a wrapping material. This device is characterized in that it comprises a pouch handling device for removing the finished pouch from the pouch making device and a wrapping material handling device for handling the wrapping material during the U-shaped wrapping of the wrapping material, wherein the handling device and the wrapping material handling device are adapted such that the pouch held by the pouch handling device and the wrapping material held by the wrapping material handling device are introduced into the sealing station.

A machine for forming filter bags for infusion products including a first movement carousel rotating continuously about a first axis of rotation; a plurality of first gripping means positioned along, and movable continuously with, the first carousel; a plurality of first operating stations positioned along, and movable continuously with, the first movement carousel; each first operating station is associated with a corresponding first gripping means; each first operating station is configured to operate on the piece of filter material in order to form, at least partly, a filter bag along a predetermined angular stretch of rotation of the first movement carousel; and a plurality of first translation devices, associated with the first movement carousel and configured for translating, mutually, the first operating stations and the corresponding first gripping means along a direction parallel to the axis of rotation.

A machine for forming filter bags for infusion products includes a first carousel including a plurality of first stations for operating on pieces of filtering material. A transfer device transfers the pieces to a second carousel. The transfer device includes a first wheel, rotatable parallel to the carousels, and including units for receiving from the first stations and releasing to the second carousel, the pieces. Each receiving unit includes 1) first gripping and stabilising devices for retaining the pieces upright and positioned with a free head end directed towards the axis of the first wheel and 2) second gripping devices for positioning and retaining a tag on the piece, fed from a corresponding feeding station, to release to the second carousel the piece with a corresponding tag alongside the free head end of the piece.

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.
