A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

The invention pertains to a method for manufacturing a tampon packaging (24), comprising the steps of: a) wrapping a strip of heat-sealable film (23) around a holding means (1, 18), whereby a first transversal end (27) of said strip overlaps with a second transversal end (28) of said strip; b) heat sealing said first transversal end (27) to said second transversal end (28), thereby forming a tube of film, and c) removing said tube of film from said holding means, thereby obtaining a tampon packaging, characterized in that said heat sealing step (b) is performed at least partly during a combined movement of said holding means (1, 18) and said strip (23). The invention further pertains to related apparatuses, systems of tampon and tampon packaging and methods for manufacturing a packaged tampon.

Herein are disclosed apparatus and methods for impinging fluids, e.g. heated fluids, onto the surface of substrates and then locally removing the impinged fluid. The apparatus may comprise at least first and second fluid delivery outlets that are in diverging relation to each other. The apparatus may comprise at least first and second fluid capture inlets that are locally positioned relative to the first and second fluid delivery outlets, respectively. The apparatus and method may be used e.g. to impinge fluids onto two converging substrates and may be used to heat the surfaces of the substrates so as to facilitate melt-bonding the substrates to each other.

A methods of executing start, run, and stop sequences on a machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge.

The present invention provides a device which can uniformize heat distribution by using an existing heater mat for repairing or joining members. A heat dispersion device includes a bag with a fluid sealed inside, and is disposed on a second surface of a heater mat which has a first surface to be directed toward an object to be heated and the second surface opposite to the first surface. The fluid inside the bag is preferably heated with a heat source.

A laminate is provided comprising at least one polysulfone and/or polyethersulfone porous membrane heat bonded to a polyvinylidene fluoride substrate.

A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.

A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

Unit and method for applying a wall to a hollow body in a manufacturing process for producing a beverage capsule; are provided: a sealing conveyor which advances along a sealing path; a sealing head conveyed by the sealing conveyor and which supports a gripping device for gripping the wall and a retaining device suited to retain the hollow body; a first feed station for feeding the wall to the sealing head, so that the wall is gripped by the gripping device; and a second feed station arranged downstream from the first feed station along the sealing path, for feeding the hollow body to the sealing head, so the hollow body is coupled to the wall gripped by the gripping device, and is retained by the retaining device.
