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 a 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).

Abstract:
A dosing device (1) for feeding an infusion product comprises a rotary drum (2) positioned between a web (3) of filter material and a hopper (4) for containing the infusion product; the drum (2) having a plurality of radial cells (5) made in it for containing the infusion product and in which there slide piston type dosing means (6); each dosing piston (6) being driven axially by respective eccentric cam actuating means (7) between two end positions, one of which corresponds to a top dead centre (PMS) where each dosing cell (5) faces the hopper (4) in order to receive a quantity of the infusion product, and the other corresponds to a bottom dead centre (PMI) where the dosing cell (5) faces the web (3) of filter material in order to discharge the quantity of infusion product onto the web (3) of filter material. Between the actuating means (7) and each piston (6) there are crank mechanisms (8) designed to act coaxially on the piston (6) in such a way as to enable the piston (6) to move in a direction that is perfectly aligned with a longitudinal axis (Z) of the respective dosing cell (5).
Abstract:
A machine for making filter bags (1) with infusion products comprises: a feed station (3) for a continuous web (S) of filter paper; a station (4) for forming and joining the continuous web (S) in a closed tubular shape which is fed along a vertical feed axis (Z); a station (5) for filling the product with a pusher element (9) able to move along the vertical feed axis (Z); a station (6) for joining an open lower end of the continuous tubular web (S) forming, alternately, the bottom end (F) and the top end (T) of individual filter bags (1); a handling and control unit for the bottom end (F) able to move in such a way that it is synchronised with the joining station (6) along the vertical feed axis (Z) for pulling the web of filter paper (S) and controlling the position of the bottom end (F) of the filter bag (1) being formed.
Abstract:
A machine for making outer envelopes (101) in which a filter bag (103) for an infusion product is wrapped in an overwrapping (S) comprises: stations for making the filter bags (103), means (106) for moving the filter bag (103) towards a station (107) for wrapping a sheet (S) of overwrapping material around the filter bag (103); and a station (109) for closing longitudinal end edges (S1, S2) and a transversal end edge (S3) of the "U"-wrapped sheet (S) to form an outer envelope (101); the closing station (109) comprises a joining carrousel (110) equipped with a plurality of sealing elements (112) which are movable in rotation with the joining carrousel (110) and designed to receive respective single filter bags (103) with the folded overwrapping sheet (S) and to allow simultaneous closing of the longitudinal edges (S1, S2) and the transversal edge (S3) of the sheet (S).

Abstract:
A machine (100) for making filter bags (1) of tetrahedral shape for infusion products (P) comprises a production line (L) defined by a series of operating stations (50, 9, 10, 14, 11, 12, 13) where filter bags (1) made from a continuous flattened tube (2) of filter paper are formed, filled with respective doses of infusion product (P) and subjected to successive cuts and closing seals (SL, ST, SC). The production line (L) extends in a direction parallel to the direction (A) and comprises, in succession, a first sealing station (50) for making the first longitudinal seal (SL) to form the tube (2) so that it extends in the horizontal direction (A); a second tube (2) sealing station (9) for making a succession of transversal seals (ST) on the tube (2) transversally to the horizontal direction (A); a cutting station (10) for cutting the tube (2) at the transversal seals (ST) so as to create a succession of filter bags (1) in the process of being formed, each having a sealed bottom end and an unsealed end (7); a station (11) for opening the unsealed end (7) of each filter bag (1); a station (12) for dosing the infusion product (P), where a dose of the product (P) is inserted into the filter bag (1) through the unsealed opened end (7); and a third sealing station (13) for making a seal (SC) that closes the end (7) of each filter bag (1) that is still open; the closing seal (SC) extending in a direction transversal to the aforementioned longitudinal seal (SL) and to the aforementioned transversal seal (ST).
