摘要:
A respiratory apparatus may employ ultrasonic welds (410). The ultrasonic welding may be used to join a variety of headgear, mask and accessory components. This process may enhance comfort, fit and/or performance of the joined components and/or overall mask assembly. A component may be a single layer component such as a textile or fabric, or a composite or multiple layer component such as fabric and foam composites, or outer fabric layers (402-1) and inner spacer fabrics (402-3). Further, a component may be a strap, some other headgear component, a mask component, an accessory component or the like.

A device including: a plurality of protruding portions of an anvil roll; an ultrasonically vibrating horn; a suction hole for drawing granular particles together with non-woven fabric sheets so as to carry the non-woven fabric sheets and to prevent the granular particles from being placed on the non-woven fabric sheets over the protruding portions; and a ridge extending along an outer circumference of the suction hole with a protruding height lower than a protruding height of the protruding portions.

The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers (740) to retain an insulating fill material. Perforations (710) along the seams (720) between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.
摘要:
An elastic laminate web is disclosed. The elastic laminate web can be non-apertured or apertured, and comprises a first web, and a second web joined to the first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2. The first and second webs form an interior region therebetween. An elastic material is disposed between the first and second webs. The elastic material is apertured in regions coincident the bond sites, such that the first and second webs are joined through the apertures. The laminate so produced can be stretched in a predetermined direction, such as by incremental stretching, to produce an apertured elastic laminate.

The invention concerns a method of producing a transdermal therapeutic system for the release of active substances to the skin in the form of a flat multi-chamber or multi-chamber channel system, in which a film containing the active substances is fitted between a top film and a bottom film. Subsequently, the top and bottom films are pressed together at discrete and/or adjacent points so that the corresponding points between them in the film containing the active substances are displaced and chambers or channels containing the active substances are formed, the top and bottom films being permanently joined, at the same time or later, at the points at which they are pressed together.

The present invention relates to a method for manufacturing a cushion material sheet comprising a number of expandable air bags provided continuously. In the present invention, a cushion material sheet comprising a number of air bags provided continuously and accomodating blown tubes is manufactured in a series of continuous steps. Films (f1, f2) taken out from rolls (1, 2), respectively, and films (F1, F2) taken out from rolls (3, 4), respectively, are superimposed one upon another so as to form one sheet, and the films (f1, f2) are heat-sealed by means of a first mold (6c) at a first operating station (S1) so as to form a main trunk passage (28) and self-sealing type valves (21, 23, 25, 27). At this time, in order to prevent the films (f1, f2 and F1, F2), from being welded together, non-welding sheets (T1, T2) are interposed between the respective films in advance. The films (F1, F2) are heat-sealed on the sides thereof in a second operating station (S2), and the films (F1, F2) are then heat-sealed in a transverse direction at a predetermined interval to thereby continuously form independent air bags (15).
