Technical Examples

A machine (1) for making filter bags (4) of tetrahedral shape for infusion products comprises a revolving conveyor drum (15) driven by a first drive shaft (16) to feed a web (5) of filter paper along a path (P) on which there are positioned: a station (25) for feeding the filter paper web (5); a station (21) for feeding a succession of tags (6); a station (22) for feeding tie string (7) connecting the filter bags (4) to the respective tags (6); a station (23) for arranging the tie string (7) according to a defined pattern on the path (P); and a plurality of sealers (24) facing the path (P) to attach the tie string (7) and the tags (6) to the filter paper web (5). The sealers (24) perform a defined movement between a sealing position and a waiting position, and this movement, which is performed simultaneously and synchronously by all the sealers (24), is imparted, through a transmission element (39) shared by all the sealers (24), by a second cam drive shaft (36) connected to the same source of motion (18) to which the first shaft (16) that drives the conveyor drum (15) is connected.
