Abstract
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.
