Chemical barrier fabric
A chemical barrier fabric and a method of manufacturing the fabric is provided. The chemical barrier fabric includes at least first and second chemical barrier layers which have an interfacial region therebetween and which are intermittently point bonded providing a point-bonded area which is in the minority and an un-bonded area which is in the majority in the interfacial region. The chemical barrier layers typically comprise single layer polymer films and/or co-extruded layers. A non-woven layer may also be point-bonded to either the first or the second chemical barrier layer to give support to the fabric.
Method for producing layered article
Provided is a method of producing a layered article by which a sufficient production speed can be achieved, and preferably, a variation in fusion strength can be suppressed and hence a variation in product quality can be reduced. The method of producing a layered article of the present invention includes fusing at least part of a single-layer body or a laminate including at least one layer including a non-woven fabric of fiber having a fiber diameter of 100 m or less through ultrasonic welding.
ELECTRODE PACKAGE AND SEALING APPARATUS
An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.
SYSTEM AND METHOD FOR SEALING A PLASTIC ENCLOSURE
A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.
POLYMER FABRICATION METHODS
There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.
Electrode package and sealing apparatus
An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.
Method and apparatus for manufacturing a tampon packaging
A method and apparatus for manufacturing a tampon packaging where the packaging is manufactured separately from the tampon. A first transversal end is overlapped with a second transversal end of a strip of heat-sealable film. The first transversal end is heat sealed to the second transversal end of the heat-sealable film, thereby forming a tube of film.
AIR CUSHION INFLATION MACHINE
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.
Sealing device
A sealing device incorporated in a packaging machine heat-seals a vicinity of a bag mouth of a packaging bag. Paired heater bars are disposed opposite each other so as to be openable/closable and hold the vicinity between them when closed, thereby heat-sealing the vicinity. A link mechanism converts rotation of an output shaft of a servomotor to an opening/closing operation of the heater bars. A storage unit stores seal patterns, each of which includes a sealing pressure applied to the parts and a sealing time period for which the parts are continuously held. A selection unit is configured to select one seal pattern. The output shaft is rotated by a predetermined closing angle according to the sealing pressure of the selected seal pattern to close the heater bars. The heater bars are maintained in the closed state for the sealing time period of the selected seal pattern.
Laminated foam product and methods for making laminated foam products
Thermally laminated foam boards, methods for making thermally laminated foam boards, apparatus for making thermally laminated foam boards, smaller foam pieces made from thermally laminated foam boards, methods for making smaller foam pieces from thermally laminated foam boards, parts made from thermally laminated foam boards, methods for making parts from thermally laminated foam boards, and tools for making parts from thermally laminated foam boards are disclosed. The thermally laminated foam boards are made by thermally bonding at least two polystyrene boards together.
