Abstract: The present invention relates in particular to a set (2) of filters (10) made of cardboard or cellulosic material. In particular, the set is characterised by the fact that it is in the shape of a generally cylindrical stick which is made up of a plurality of individual filters (10), each formed of a winding on itself of a side made of cardboard or cellulosic material, said filters (10) being arranged in extension of one another and being partially connected in pairs by connecting means (3), such that it is possible to separate at least one filter (10) from. tile stick by removing or severing tile connecting means (3).

Abstract: The present invention relates in particular to a foldable container (1) for loose tobacco, which is delimited by two longitudinal walls (10, 11) which have a common longitudinal edge (101), and by two opposite transverse walls (12, 13) shaped like bellows, characterized by the fact that said transverse walls (12, 13) shaped like bellows consist of five successive pleats (P1, P2, P3, P4, P5), and that the two adjoining transverse wall elements (122, 123) which constitute at least one (P4) of said pleats are configured to occupy either a first position in which they form a re-entrant corner, or a second position in which they form an outer corner and thus constitute a pouring spout.

Abstract: The invention relates to a cardboard filter (1) for cigarettes, formed by folding, winding and gluing a cardboard strip (2). According to the invention, the cardboard strip (2) is folded to form a central portion (21) having a series of lobes (3, 4, 5, 6, 7) angularly equally distributed around a central axis (22) of the filter (2) and a peripheral portion (23) surrounding the central portion (21), the lobes (3, 4, 5, 6, 7) and the peripheral portion (23) delimiting gas passage channels (24) around the central axis (22).

Abstract: The invention provides a machine for filling cigarette tubes, the machine comprising a spoon (120) receiving a load of tobacco and shaping it into a cylinder, an endpiece (210) on which a cigarette tube is placed, a clamping device (330) suitable for clamping such a tube onto the endpiece, and a slide (200) which carries said endpiece and which is movable in translation along the spoon (120), the machine further comprising an end abutment arrangement (130) for the tobacco, the arrangement being directed in such a manner as to hold the tobacco in the direction of the tube to be filled, the machine being characterized in that said abutment arrangement (130) comprises a contact piece (131) making contact with the tobacco, which contact piece is movable between at least two positions, one position in which said contact piece (131) occupies a portion of the tobacco-receiving zone in the spoon (120), and another position in which it leaves said portion empty, such that the extent of the fill of tobacco introduced i
