The present invention relates to a device and a method for manufacturing a bag received in an envelope and containing a brewable material with a bag manufacturing means which is configured to manufacture a bag containing brewable material, and with a sealing station with a sealing jaw element and a counter-jaw element which act on the envelope from opposite sides to seal in the bag. The device is further developed for a reliable and safe manufacture of the packing unit consisting of a bag and an envelope by the sealing jaw element being fixed to a sealing jaw swivel arm at which a sealing jaw connecting rod is applied, and the counter-jaw element being fixed to a counter-jaw swivel arm at which a counter-jaw connecting rod is applied, and by the sealing jaw connecting rod and the counter-jaw connecting rod being each eccentrically connected to a common drive shaft of a servomotor. In the method according to the invention, the contact force between the sealing jaw element and the counter-jaw element is controlled via the torque of the servomotor actuating the sealing jaw element and/or the counter-jaw element.

A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

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.
