Abstract: An overwrap envelope (7) containing a filter bag (1) for infusion products comprises a sheet (2) of overwrapping material folded into a U shape along its transversal axis (X) around the filter bag (1). The overwrap envelope (7) has two longitudinal sides (3, 4) and one transversal side (5) sealed by at least two sealing lines (6) which are uninterrupted along the longitudinal sides (3, 4) and along the transversal side (5). Each scaling line (6) is defined by two longitudinal stretches and one transversal stretch which are joined to obtain an uninterrupted shape and which form an uninterrupted perimeter seal.

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 synchronized 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 beverage capsule machine for making single use capsules (1) for infusion beverages such as coffee, milk, chocolate, tea or combinations of these ingredients, comprises: a transport element (8) for transporting rigid containers (2) and being dosed in a loop around movement means (9), with a vertical axis (Z9), for continuously moving the transport element (8); the element (8) being configured to define a plurality of pockets (10) for receiving the rigid containers (2) and arranged in succession, each having a respective vertical axis (Z10); a plurality of stations which are positioned along a path (P) followed by the transport element (8) and which are configured for operating continuously in phase with the transport element (8) and comprising at least: a feeding station (11) for feeding the rigid containers (2) into the respective pockets (10) of the transport element (8); a dosing station (12) for dosing the infusion product into the rigid container (2); a closing station (13) where the open aperture (4) o

Abstract: A method for producing a single-use capsule (1) for extraction beverages comprises the steps of: positioning a flat piece (8) of filter paper over a cup-shaped rigid body (2); joining the flat piece (8) of filter paper along at least the rim (7) of the rigid body (2); forming the piece (8) of filter paper towards the interior of the rigid body (2) and by means of plastic deformation of the piece (8) of filter paper so as to define a containment chamber (5); filling of the containment chamber (5) with a dose (D) of product; closing of the chamber (5) and of the external rigid body (2) with a sheet lid (6). This invention also relates to a machine (100) which implements said method.
