A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

A system includes a source, a detector, and a controller. The source is configured to emit electromagnetic energy toward two plies of film. A portion of the emitted electromagnetic energy is within a range of wavelengths. The detector is arranged to detect electromagnetic energy propagating away from the two plies of film. The detector detects electromagnetic energy within the range of wavelengths and generates signals indicative of intensity of detected electromagnetic energy. The controller controls operation of the foam-in-bag system based the signals from the detector. The film is transmissive of electromagnetic energy in the range of wavelengths. When dispensed between the two plies of film, one or both of foaming chemical precursors or foam formed from a reaction thereof is opaque to electromagnetic energy in the range of wavelengths.

A system includes a dispenser, first and second feed lines, and heating zones. The dispenser dispenses a first chemical precursor and a second chemical precursor. The first feed line permits flow of the first chemical precursor from a first source to the dispenser. The second feed line permits flow of the second chemical precursor from a second source to the dispenser. The heating zones are located along the first and second feed lines. The heating zones include a first heating zone located around a first portion of the first feed line and a second heating zone located around a first portion of the second feed line. The first heating zone and the second heating zone are independently controllable to independently control temperature around the first portion of the first feed line and temperature around the first portion of the second feed line.

A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

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 system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

The present invention relates to a nozzle for cleaning a substrate capable of spraying deionized water for cleaning a substrate to the substrate, the nozzle including a first body made of a resin material and provided with a first part of a deionized water passage and a deionized water supply hole to supply the deionized water, a second body made of a resin material and provided with a second part of the deionized water passage and a plurality of spray holes to spray the deionized water to the substrate, a fusible protrusion provided in the first body or the second body along the deionized water passage and configured such that a part thereof is fused during ultrasonic welding, so as to couple the first body and the second body together, and a fusible protrusion accommodating part formed in the first body or the second body to accommodate the fusible protrusion.

Systems and methods are presented herein for a method of attaching a strip to a housing. An internal support member is inserted into a collapsible housing, such that it is arranged along a longitudinal axis of an inner surface of the collapsible housing. An outer support member is arranged along an outer surface the collapsible housing opposite the internal support member. A strip is positioned along the outer surface using the outer support member and the internal support member. Then the strip is permanently welded to the outer surface using a welding element. Welding is performed by a welding element located in one (or both) of the internal support member or the outer support member.

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.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.
