Abstract
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.
