A machine for grouping filter bags for infusion products includes: a movement wheel rotating about a first axis; a rotary transfer wheel, rotating in a synchronised fashion with the movement wheel, about a second axis; a device for collecting the bags; a plurality of gripping elements positioned along a circumference of the transfer wheel and movable with it for picking up, in a first angular position, a bag from the movement wheel and a release configuration of the bag in the collecting device, in a second angular position and after an angular stretch of rotation. A sensor detects possible defects of the bags, and identifies the defective bags before they reach the second angular position. A rejection area receives the defective bags. A locking control controls the gripping element to prevent release of the bag in the second angular position, when detected to be defective by the sensor.

Machine for grouping together filter bags for infusion products

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.
