The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

Provided is a production method for a freshness-keeping bag capable of reducing the inflow of oxygen from the outside of the bag to a very low level, and thereby keeping the freshness of a content thereof for a long period of time. The present invention provides a method for producing a freshness-keeping bag formed of a film, wherein the freshness-keeping bag has a band-shaped joining region in which two ends of the film are overlapped and joined together, the joining region comprising a plurality of joined parts in which the two ends of the film are joined together, and a non-joined part which is located between adjacent ones of the joined parts and in which the overlapped ends of the film are not joined together, the non-joined part composing a non-linear ventilation passage communicating between an internal space of the bag and the outside of the bag, the method comprising the step of forming the joined parts by ultrasonic welding, wherein the step of forming the joined parts includes continuously forming the joined parts in the film, while rotating a disk-shaped ultrasonic welding anvil with respect to the film, wherein the ultrasonic welding anvil has a plurality of protrusions formed on an outer periphery thereof continuously at given intervals and correspondingly to the configuration of the joined parts of the bag.

Interfaces for positive pressure therapy having a mask assembly, a headgear assembly and a connection port assembly are disclosed herein. The connection port assembly has a ball joint connection with the mask assembly and includes a quick release button for easily disconnecting the gases source conduit from the mask assembly. The mask assembly may include a bias flow vent that is formed separately and attached to the mask assembly. The headgear assembly encircles the rear region of the user's head and may include at least some portions that are substantially non-stretchable.

A method of joining overlapping thermoplastic roofing membrane components in which a first thermoplastic roofing membrane component and a second roofing membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces. Heat is generated in a metal substrate and transferred by thermal conduction from the metal substrate to overlapping portions of the first and second thermoplastic roofing membrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic roofing membrane component and a portion or more of the thermoplastic material of the second thermoplastic roofing membrane component. The molten thermoplastic material of the first and second thermoplastic roofing membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

A method of joining overlapping thermoplastic geomembrane components in which a first thermoplastic geomembrane component and a second thermoplastic geomembrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with one or more of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic geomembrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic geomembrane component and a portion or more of the thermoplastic material of the second thermoplastic geomembrane component. The molten thermoplastic material of the first and second thermoplastic geomembrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

A melting heater configured to melt joining end surfaces of a pair of semi-molded products in a case where the joining end surfaces are melted and joined to manufacture a molded product, the melting heater including: two glass plates arranged in parallel to each other; and a plurality of element heaters arranged in a unit having a flat plate shape as a whole between the two glass plates, in which the glass plate is subjected to surface processing for controlling infrared rays emitted from the plurality of element heaters.

The present invention relates to a simplified device and a process-technically simplified and also more rapidly applicable method for transporting readily cut and filled hose pieces within a machine for producing pouches filled with brewable material. The device according to the invention has a transport wheel which has several supports distributed over its circumference, each holding a pouch which are pivotally mounted on the transport wheel. In the method according to the invention, a hose piece for forming a pouch with at least one chamber between a head and a bottom is inserted in the radial direction into a support of the transport wheel. In a removal station the pouch is removed radially from the transport wheel with the bottom leading.

The present invention relates to a device for manufacturing a pouch containing a brewable material accommodated in a wrapping, comprising a pouch manufacturing device adapted to manufacture a pouch containing brewable material, and a sealing station with jaw elements forming opposing sealing surfaces acting on the wrapping from opposite sides for sealing the pouch. The device according to the invention allows a more economical production of a packaging unit comprising a pouch in the wrapping and has a trough-shaped recess in which a helically laid heating conductor is accommodated.
