Abstract: A single-lobe filter bag for infusion products comprises: a length (2) of filter material forming a chamber (3) containing a charge of the infusion product; the length (2) comprises a first closed top end (5) formed by a first join (S1) between two first end edges of the length (2); a second bottom end (7) closed by a second join (S2) designed to form a bottom surface (11) of the filter bag (1) and formed by two second end edges (7a, 7b) placed over each other to form a central extension of the second end (7); the second end edges (7a, 7b) are positioned face to face with each other and joined in such a way as to form a tab (12) that protrudes from the bottom surface (11); two sides (8, 9) which connect the first end edge (5) and the second end edge (7) and which are at least partly folded onto each other to form a fold towards the inside of the chamber (3); a string (13) joined, at one end, by a knot (A1) to the length (2) and, at the other end, by a knot (A2) to a tag (14), the string (13) being looped arou

Abstract: A machine (100) for making filter bags (1) for infusion products, the machine (100) being of the type comprising, one after the other along a production line (P), a plurality of operating stations designed to form the filter bags (1) and at least one operating outfeed station (7) for handling the filter bags (1) made; the operating outfeed and handling station (7) comprises conveying means (8) designed to successively pick up and withhold the filter bags (1) along a certain section (T1) of the line (P); supporting guide means (9) along which an ordered and continuous succession of filter bags (1) is formed and fed along another section (T2) of the line (P); and means (11) for picking up and transferring the filter bags from the conveying means (8) to the supporting guide means (9).

Abstract: A single-lobe filter bag for infusion products comprises a length (2) of filter material forming a chamber (3) containing a charge (4) of the infusion product. The length (2) comprises: a first closed top end (5) formed by a first join (S1) between two first end edges of the length (2); a second closed bottom end (7) and two sides (8, 9) connecting the two ends (5, 7) of the length (2); the two sides (8, 9) connecting the first and second edges (5, 7) are at least partly folded onto each other to form a fold towards the inside of the chamber (3) and the second bottom end (7) of the filter bag (1) is closed by second join (S2) designed to form a rigid flat bottom surface (11) of the filter bag (1) such as to define a stable base, with a substantially triangular cross section, for supporting the filter bag (1).
