Abstract
A packaging machine for making filter bags with infusion products includes a plurality of processing stations defining a processing path for making filter bags with infusion products and an extraction station situated immediately downstream of the processing path. The extraction station comprises a stacking unit having a guide channel to allow the ordered and continuous feeding of the filter bags and a transfer device for transferring the filter bags coming from the processing path to the stacking unit. The stacking unit includes a connecting element positioned downstream of the processing stations and upstream of the guide channel for receiving as input from the transfer device the filter bags coming from the processing path. The connecting element is connected at the outlet with the guide channel and includes a chute surface having a curved stretch shaped to allow feeding of the filter bags along a feed direction.
