A machine for forming filter bags for infusion products, starting from pieces of filter material feeding along a feed line, includes: a movement carousel rotating continuously about an axis; a plurality of grippers positioned along, and movable continuously with, the carousel, each gripper configured for retaining a respective piece of filter material; a plurality of operating stations positioned along, and movable continuously with, the carousel; each operating station associated with a gripper and configured to operate on the piece of filter material to form, at least partly, a filter bag along a predetermined angular stretch of rotation of the carousel; a plurality of translation devices, associated with the carousel and configured for translating a gripper along a direction parallel to the axis to bring the corresponding gripper to the respective pieces of filter material at least for a stretch of the feed line.

A machine for forming filter bags for infusion products includes a carousel and a transfer wheel with a plurality of gripping devices. A plurality of control devices control the gripping devices between a first operating position for receiving a filter bag from the carousel or for releasing the filter bag in a collection zone, and a second operating position for retaining the filter bag. A control unit measures defects in the filter bags. An auxiliary control device is located on the transfer wheel and connected to the control unit for controlling, selectively, the passage from a second operating retaining position to a first release position on a predetermined gripping device and along an angular stretch of rotation of the transfer wheel, at a control signal of the control unit generated in the presence of a defective filter bag, to release the defective filter bag in a different collecting zone.

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 machine for manufacturing pouches containing a cohesionless material, including feed means for feeding the cohesionless material to a pick-up station, a transfer drum by which the material is picked up at the pick-up station and transferred to a release station, delivery means operating at the release station and by which portions of the material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches, and a mixer located at the pick-up station for performing a mixing action on the material at the pick-up station before the material is picked up by the transfer drum.

Packaging apparatus comprises two counter-rotatable sealing dies for pressing together two tissue webs to produce pockets for containing a substance for preparing beverages and to seal around said pockets, and two heating drums for heating the sealing dies and each being positioned inside a respective sealing die, wherein a first heating zone of each heating drum comprises a first plurality of circumferentially distributed infrared heating elements, and a second heating zone of each heating drum comprises a second plurality of circumferentially distributed infrared heating elements.

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.

The disclosure relates to a method for unpacking and separating infusion bags into singles for supplying the bags to a device for further processing. It includes the following steps: Opening an outer packaging, in which the infusion bags are present, by an opening device, wherein the infusion bags are fastened in groups to a holding device inside the outer packaging. Separating the group of infusion bags, which are fastened to the holding device, from the outer packaging by a separating device. Position the holding device with the infusion bags fastened thereon in a transport device by a positioning device. Processing the infusion bags by device for further processing.

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.

The present invention relates to a device for transporting ready-cut and filled pieces of tube. In order to simplify the structural design of a device for transporting ready-cut and filled pieces of tube within a machine for producing double-chamber bags filled with brewable material, having a transport wheel, which has distributed over its circumference a plurality of double-chamber bag forming sets comprising a leading arm and a trailing arm and a profile part provided therebetween and being radially movable and supporting a bottom of a double-chamber bag, and which is rotatably mounted under a cover arranged in the vicinity of the upper vertex of the transport wheel, the present invention proposes that the arms are swivelably mounted eccentrically to the axis of rotation of the transport wheel and that the arms of adjacent double-chamber bag forming sets are swivelably mounted on a common swivel axis.
