The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers to retain an insulating fill material. Perforations along the seams 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.

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

A method of manufacturing feather-filled items of clothing includes the following steps: preparing at least one mold provided with first concavities of shape substantially complementary to a respective padded cambered region of at least one portion of the item of clothing to be obtained; and associating a first sheet of deformable material with the mold. The method further includes deforming the first sheet against the mold so as to obtain, on the first sheet, second concavities that substantially correspond to the first concavities of the mold. Then, each second concavity of the first sheet is filled with down, and a second sheet is anchored to the first sheet. The semi-finished product is removed from the mold.

The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.

Embodiments of the present invention provide reinforcements for inflatable device assemblies. Specific embodiments provide a welded reinforcement for crotch areas of inflatable devices. Particular benefits may be achieved when the areas to be reinforced with the reinforcement system described are non-linear, defining a geometry with at least one curve or angle. Specific aspects of the reinforcement system provide one or more precut gusset elements that are configured to be secured with respect to a crotch area of a base substrate and welded.

An automatic bonding apparatus and a method for thermally induced seam bonding of weldable and/or gluable flat flexible material layers with each other which are each configured as a material web, material band and/or material piece and arranged so that they overlap at least partially wherein the bonding is performed by an electrically controlled contact heating arrangement through a heating wedge welding method. A temperature and/or a power of the heating wedge which is formed by a thin folded steel sheet blank is controlled as a function of a relative velocity between the material layers and the automatic bonding apparatus. This is performed so that a thermal energy that is transferred from the heating wedge to the material layers to be glued is kept constant. For this purpose the relative velocity is detected and the power of the heating wedge is automatically adjusted when the relative velocity changes.

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a scam, overlaying the seam with a tape made of the same selected material, and scaling the tape and seam using a radio frequency (RF) welding machine.
