Abstract:
A component assembly includes a first part having a transparent section. The first part defines an outer surface. A second part is fixedly secured to the first part at a portion of the transparent section. The first and second parts create a connecting seam through the portion of the transparent section. An optically covering surface extends between the connecting seam and the outer surface of the first part to cover the connecting seam from view from the outer surface.
Abstract:
A stitchless seam comprises a first portion of material folded upon itself proximate an edge to define an overfolded end portion having overlapping edge and nonedge portions and a second portion of material positioned adjacent the overfolded end portion. A first portion of adhesive is interposed between the overlapping edge and nonedge portions and a second portion of adhesive is interposed between the second portion of material and the edge portion of the overfolded end portion. Energy may be applied, via an ultrasonic seam bonding machine or other means, to activate the adhesive portions. The seams may be used for items made of waterproof breathable laminate fabric material, such as garments and sports articles.
Abstract:
A method of forming a stitchless, adhesively bonded seam involves placing a first strip of adhesive (9) between the outside surface of first and second sheets of material (1, 2) along an edge (8) of the second sheet. At least a portion of a second strip of adhesive (13) is positioned against a first portion (17) of the inside surface (7) of the second sheet along the edge thereof. The second sheet of material is folded such that a second portion (18) of the inside surface overlies the second strip of adhesive. In some embodiments the first and second strips of adhesive are replaced by a single longitudinally folded strip of adhesive. Energy may be applied, via an ultrasonic seam bonding machine or other means, to activate the adhesive. Seams made according to the disclosed methods may be used for garments, sports articles, and other items made of fabric or other sheet material.
Abstract:
A method of forming a stitchless, adhesively bonded seam for a garment includes positioning an outside surface of a first sheet of fabric adjacent to an outside surface of a second sheet of fabric, and positioning a first strip of adhesive tape between the first and second sheets of fabric. A second strip of adhesive tape is positioned such that a first side is adjacent to a first portion of an inside surface of the second sheet of fabric, and the second sheet of fabric is folded such that a second portion of the inside surface of the second sheet of fabric overlaps a second side of the second strip of adhesive tape. The adhesively bonded seam is formed by applying energy to the first and second sheets of fabric and to the first and second strips of adhesive tape.
Abstract:
The present invention provides a method of forming a stitchless, adhesively bonded seam for a garment. The method includes providing a first and second sheet of fabric with each sheet having an outside or facing surface, an inside or backing surface, and an edge. The outside surface and edge of the first sheet of fabric are positioned adjacent to the outside surface and edge of the second sheet of fabric, respectively. A first strip of adhesive tape, having first and second sides and an edge, is positioned between the first and second sheets of fabric such that the edge of the first strip of adhesive tape is adjacent to the edges of the first and second sheets of fabric, and the first and second sides of the first strip of adhesive tape are adjacent to the outside surfaces of the first and second sheets of fabric, respectively. A second strip of adhesive tape, having first and second sides and an edge, is positioned such that its edge and first side are adjacent to the edge of the second sheet of fabric and to a first portion of the inside surface of the second sheet of fabric, respectively. The second sheet of fabric is folded such that a second portion of the inside surface of the second sheet of fabric overlaps the second side of the second strip of adhesive tape. The adhesively bonded seam is formed by applying ultrasonic sound pressure to the first and second sheets of fabric and to the first and second strips of adhesive tape, causing the first strip of adhesive tape to join the outside surfaces of the first and second sheets of fabric and the second strip of adhesive tape to join the first and second portions of the inside surface of the second sheet of fabric.
Abstract:
A method of strengthening a boundary region between a first portion and a second portion of a fibrous body for absorbent articles. This boundary region is provided with a pattern of compressed spots, the amount of compression being gradually increasing in a direction leading away from an edge of the first portion of the fibrous body. Also, an apparatus for performing the method and an absorbent body having a strengthened boundary region.
Abstract:
A rubber article, such as a tire, composed of at least two rubber mixes with different composition and properties, the said two mixes having a lap joint characterized in that at least one edge of at least one of the two mixes has an end with an oscillatory trace-line.
Abstract:
A method for sealing a container comprising a cup and lid is disclosed. The cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.
Abstract:
A water reservoir for a clothes pressing iron, the reservoir being composed of two plastic parts, and a method for fabricating the reservoir by: simultaneously molding the two parts of one reservoir in a first injection molding step in two impressions of the same mold; and assembling the two parts together while, in a second injection molding step, injection molding a joint of plastic material between the two parts to connect the two parts together in a fluid-tight manner, wherein the two parts are assembled together and the second injection molding step is performed before complete crystallization of the two parts.
Abstract:
A hollow container is formed with a thin-walled, plastic body; and a discrete plastic handle is attached by ultrasonic energy to the plastic body. The handle has a pair of spaced bosses at each end of the handle with a central opening therein to receive an ultrasonic horn. A plurality of integral, energy-directing protrusions are spaced from one another on the bosses to be melted and mixed with the plastic of the container. The energy directors melt first and mix with the plastic of thin-walled bottle to provide a secure attachment. The preferred container and preferred handle are each made of PET plastic.
