A device for joining filter bags includes two operating units located on opposite sides of a continuous tubular strip of filter material movable along a feed direction; each operating unit includes a supporting body, a sealing head connected to the supporting body and two kinematic units equipped with a corresponding eccentric rotary system for moving the supporting body along a first trajectory and to move the sealing head between a position of contact with the strip and a position away from the strip; each operating unit includes a carriage associated with the sealing head for and slidably connected to the supporting body to translate in both directions along a second trajectory.

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.

A biodegradable whole leaf pillow tea bag is provided, along with a system and method for manufacturing biodegradable whole leaf pillow tea bags. The method for manufacturing the whole leaf pillow tea bags includes the steps of providing a biodegradable infusion substrate having two opposing edge; creating a sleeve from the biodegradable infusion substrate by infusing the two opposing edges of the substrate together and closing the sleeve at its bottom; placing whole leaf tea in the bottom of the sleeve; vertically feeding the sleeve containing the whole leaf tea into a heat sealing machine that will, at predetermined intervals create heat seals across the sleeve to create pillow bags; cutting the pillow bags from one another across the heat seal. In one example, the biodegradable infusion substrate may contain hemp and/or the whole leaf tea may be infused with CBD oil or other supplements. The same method of manufacturing may be used to create a biodegradable pillow bag containing coffee.

A machine for forming filter bags for infusion products starting from pieces of filter material each containing a dose of infusion product and having, the pieces, a corresponding longitudinal axis of extension, including a carousel rotating about a main axis of rotation and including gripping elements movable in rotation about the main axis along a closed circular trajectory; each gripping element configured to receive and retain a piece of filter material along an operating path; an operating station configured to perform an operation on the piece of filter material retained by a corresponding gripping element; each gripping element including an articulation device configured for obtaining a further rotation about a secondary axis of rotation, transversal to the main axis of rotation, to rotate and position the corresponding piece of filter material with its longitudinal axis of extension parallel to the main axis of rotation at the operating station.

Described is a device for feeding and dosing infusion or extraction product of a machine (100) for making filter bags (S) containing the infusion or extraction product comprising a space (2) for containing infusion or extraction product defined by an outer lateral wall (3) and by an inner lateral wall (4) comprising openings (7) for the passage of the product; a feeding chamber (6) made inside the inner lateral wall (4), communicating through the openings (7) with the containment space (2) and equipped with an outlet (8) leading outside the containment space (2); a shutter (9), which is movable inside the feeding chamber (6) at least between a closed lower end position (P1), wherein it occludes the openings (7), and an open upper end position (P2), wherein it allows the passage of the product from the containment space (2) to the feeding chamber (6) through the openings (7) towards the outlet (8) to fill the filter bags (S) being formed.

Described is a machine for forming filter bags (1) for infusion products, starting from pieces (1a) of filter material feeding along a feed line (A), comprising: a first movement carousel (2) rotating continuously about a first axis (2X) of rotation; a plurality of first gripping means (3) positioned along, and movable continuously with, the first movement carousel (2), each first gripping means (3) being configured for retaining a respective piece (1 a) of filter material being formed; a plurality of first operating stations (4) positioned along, and movable continuously with, the first movement carousel (2); each first operating station (4) being associated with corresponding first gripping means (3) and configured to operate on the piece (1 a) of filter material in order to form, at least partly, a filter bag (1) along a predetermined angular stretch of rotation of the first movement carousel (2); a plurality of first translation devices (5), associated with the first movement carousel (2) and configured for translating corresponding first gripping means (3) along a direction parallel to the axis (2X) of rotation of the first movement carousel (2) to bring the corresponding first gripping means (3) to the respective pieces (1a) of filter material at least for a stretch of the feed line A.
