The present disclosure relates to methods and apparatuses configured to bond elastic laminates together between a rotating drum and anvil. The drum includes a fluid nozzle and a press member. As such, a first elastic laminate and a second elastics laminate may be advanced in a machine direction onto the rotating drum. A fluid is heated to a temperature sufficient to partially melt substrate layers of the first and second elastic laminates. As the drum rotates, the press member shifts radially outward from the drum wherein a length, L, of the pattern surface extends in the cross direction across a plurality of elastic strands of first and/or second elastic laminates. And the partially melted portion of the substrate layers of the first and second elastic laminates and the plurality of elastic strands are then bonded together by being compressed between the pattern surface and the anvil roll.

There is described a forming assembly (10b) for forming a plurality of sealed packs (3) starting from a tube (2) of packaging material, comprising first conveying means (15b) movable along a first path (Q) comprising: a first operative branch (Q1), which has a main elongation direction parallel to an advancing direction (A) of the tube (2); and a first return branch (Q2) comprising an initial portion (35b) which is arranged immediately downstream of the operative branch (Q1) and extends transversally to the advancing direction (A); first conveying means (14b, 15b, 14b) comprise one of a sealing element (22b) or a counter-sealing element (22a); and a first half-shell (21b), which is movable along the operative branch (Q1) between: a first rest position, in which it is detached from the tube (2) or the formed pack (3); and a first operative position, in which it grips the tube (2) or the formed pack (3); the first half-shell (21b) is arranged in the first operative position along a first portion (34b) of the first operative branch (Q1); the first half-shell (21b) is kept in the first operative position along an initial portion (35b), so as to grip and convey the pack (3) in a staggered position with respect to the advancing direction (A); and moves, from the first operative position to the rest position at an end (36b) of the initial portion (35b) opposite to the first portion (34b), so as to discharge the pack (3) in a staggered position with respect to the advancing direction (A).

The pressure jaw assembly (1) comprises a pressure jaw frame (10), a pressure element (20) arranged to be moved relative the pressure jaw frame (10), a compressing means (40) arranged at least partly between the pressure jaw frame (10) and the pressure element (20). The compressing means (40) is arranged to influence the relative movement between the pressure element (20) and the pressure jaw frame (10). The pressure jaw assembly (1) further comprises a guide (50, 52) for guiding the pressure element (20). The guide (50, 52) is connected to the pressure jaw frame (10), and the guide (50, 52) is arranged externally of the pressure element (20).

An apparatus for joining substrate portions includes substrate portions being positioned such that the substrate portions overlap at an overlap area. The substrate portions each have a melting temperature and an outer surface. A fluid is heated to a temperature sufficient to at least partially melt the substrate portions. A jet of the heated fluid is directed from a fluid orifice onto the substrate portions at the overlap area. The heated fluid penetrates at least one of the outer surfaces of the substrate portions. The substrate portions are at least partially melted using the heated fluid. The substrate portions are compressed using a pressure applying surface adjacent the fluid orifice to join the substrate portions together at the overlap area.

An apparatus includes a drum that rotates about an axis and rotating an anvil roll that rotates about an axis of rotation. The drum includes a fluid nozzle and a press member, the press member having an outer surface. The anvil roll includes a compliant outer circumferential surface. First and second substrates are advanced in a machine direction onto the drum. The fluid nozzle moves radially outward and a jet of heated fluid may be directed onto the substrates. The fluid nozzle retracts radially inward and the press member may be shifted radially outward. The substrates may be compressed between the press member and the anvil roll such that the press member deforms the compliant outer circumferential surface of the anvil roll.
