The present invention relates to a simplified device and a process-technically simplified and also more rapidly applicable method for transporting readily cut and filled hose pieces within a machine for producing pouches filled with brewable material. The device according to the invention has a transport wheel which has several supports distributed over its circumference, each holding a pouch which are pivotally mounted on the transport wheel. In the method according to the invention, a hose piece for forming a pouch with at least one chamber between a head and a bottom is inserted in the radial direction into a support of the transport wheel. In a removal station the pouch is removed radially from the transport wheel with the bottom leading.

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 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.

The invention discloses a manufacturing method for a tea bag folding structure comprising: a fold-to-overlap step and a press-to-fold step. The fold-to-overlap step is to overlap a sheet having a plurality of folding lines and join two opposite side edges thereof, and the press-to-fold step is to open the sheet into a hollow cylinder shape and fold the sheet into a cylindrical folding structure with openings at both ends along the plurality of folding lines. In the manufacturing method, after the tea bag folding structure is formed, one end opening of the tea bag folding structure is closed, the tea bag folding structure is filled with tea leaves, and the other end opening of the tea bag folding structure is closed.
