The invention is directed to a thermoforming packaging machine (1) for producing sealed packages (2) having a planar surface (3) and a shaped recess (4) comprising a sealing station (6) with a lower sealing tool (7) comprising of a first part (8) provided with a first seal seam support (8a) for supporting a first sealed seam (9) at the outer perimeter (10) of the planar surface (3) of the moulded product (2a) and a second part (11) provided with a second support (11a) provided with a seal seam support opening (12). The second support (11a) supports a second sealed seam (12a) on the planar surface (3) of the moulded product (2a) following the perimeter (13) of the shaped recess (4). The first part (8) and the second part (11) are separate parts which are detachable connected.

A packaging material sealing device, in particular cross seam packaging material sealing device for a vertical packaging machine, includes a first sealing jaw and at least a second sealing jaw, at least one movement unit for actuating the two sealing jaws along a sealing direction, and at least one control unit. In at least one operating state the control unit controls a rotation of the two sealing jaws relative to a transport direction of a packaging material. At least two guiding rails of the movement unit for moving the two sealing jaws along at least the sealing direction each have clearance with respect to their bearings in order to allow rotation of the two sealing jaws relative to the transport direction.

A packaging material sealing device includes a first sealing jaw and at least a second sealing jaw and at least one movement unit, which includes a first actuator and at least a second actuator for actuating the two sealing jaws along a sealing direction, and at least one control unit. In at least one operating state, the control unit controls the two actuators for setting an asymmetrical sealing force for the two sealing jaws.

A heat-sealing device is capable of properly changing a pushing force applied from the heat-sealing roll to the packing film in accordance with the feeding rate of the packing film. A heat-sealing device for holding an elongated packing film with a pair of heat sealing rolls arranged in parallel to each other to form a heat sealed portion includes a pushing means made of a first cylinder and a second cylinder for holding the packing film with the heat-sealing rolls by pushing through an action of fluid pressure, a fluid pressure controlling means capable of adjusting the fluid pressure of the pushing means, and a superior controlling means for rendering a total value of pushing forces of the first cylinder and second cylinder into a proper pushing force and operating one or both of the first cylinder and the second cylinder in accordance with the feeding rate of the packing film.

Systems, apparatuses, and methods to secure a film to a container are provided. An example sealing device utilizes film from a supply of film to seal a lid onto a container. Various sizes of containers are usable with some example sealing devices. Additional features, such as printing on the film and piercing the film for ventilation and/or insertion of a straw are contemplated. One or more markings along the film may be utilized for confirming that an approved film has been loaded into the sealing device. In response, various components or features of the sealing device may be appropriately enabled or disabled. The one or more markings may also be utilized to convey data to the sealing device regarding the installed film, such as for improved operation thereof.

A hybrid electrofusion processor selectively operating on either battery power or AC power.

An installation for welding a stack of parts made of thermoplastic composite materials (20) in a local welding plane (P), this installation including an electromagnetic induction head (8), pairs of elements for guiding and pressing the workpiece stack (20) in this local plane (P), and, on each side of the induction head (8), at least one pair of guide elements, each pair of guide elements having a lower guide element (14) and an upper guide element (10) that are superposed, receiving between one another the stack of parts (20) by guiding it in the direction perpendicular to the local welding plane (P).

A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.

An apparatus may include a film support roller supporting a film roll and a housing that may include a sealing portion having an aperture sized to receive a top portion of a container. The housing may define a film path leading from the film roll to the sealing portion. A guide support assembly may have a ramp and at least one guide truss positioned along the film path. The ramp and the guide truss may guide the film across the aperture within the sealing portion, covering the aperture. The motor may advance the film along the film path. The heating element may emanate energy. The controller may cause the motor to advance the film onto the ramp and cause the heating element to emanate energy to cause the film to seal the top portion of the container.
