Abstract:
A device (1) for feeding a product, in particular an infusion product, to a packaging machine is of the type comprising means (2, 6) for collecting and transporting the product and means (8) for conveying the product itself. The conveying means (8) are of the type with vibrating channelling means and are connected to the collection means (2, 6) to receive the product from the collection means (2, 6) and to feed the product to an operating station (10) of the packaging machine.
Abstract:
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.
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 (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).
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 (Sl) 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 (Al) to the length (2) and, at the other end, by a knot (A2) to a tag (14), the string (13) being looped around the length (2).
