Apparatus and methods are provided to allow for creation of an elastic laminate. Non-stretched elastic can be laid at peaks over a nonwoven layer contained in valleys and atop peaks. Stretched elastic can be laid over tented nonwoven to create nonwoven tunnels when a second nonwoven is laid atop the first nonwoven and elastic, and the tunnels resist un-stretching of stretched elastic strands by frictional or obstruction forces. An elastic assembly or structure comprising a first and second layer of material bonded at spaced apart bond sites is disclosed, with a plurality of elastic strands disposed in a non-linear manner between said first and second layer of material, so that said strands meander in a cross-machine direction and traverse a machine direction line, restraining movement of the strands by frictional forces between the strands and the non-woven layers.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

The outer edge of a filtration membrane is thermally welded to a filter plate by a first thermal welding part. The first thermal welding part includes an outer boundary line disposed inside an outer edge of the filter plate and an inner boundary line disposed inside the outer boundary line. The outer boundary line has a plurality of first projected portions and first recessed portions that are alternately formed. The first projected portion projects toward the outer edge of the filter plate, and the first recessed portion is formed between the first projected portions and retracts in an inward direction A opposite to the outer edge of the filter plate.

An automobile interior trim has a resin core material and a skin material that is joined on a surface of the resin core material. The automobile interior trim has stitches that are formed on the skin material by sewing the skin material with threads. The skin material and the stitches are cut by a laser beam to generate a cut section. The vicinity of the cut section has a structure in which threads of the stitches and the raw material of the skin material are melted by heat of the laser beam, mixed together, and solidified.

Using a conveyance roller having an outer peripheral surface which is capable of conveying two sheets with an elastic element sandwiched therebetween, in a longitudinal direction of the sheets, and formed with a convex section; and a clamping and pressing device, the sheets with the elastic element sandwiched therebetween are ultrasonic-welded together under pressing. The convex section is formed in a shape extending along a line intersecting a conveyance direction of the conveyance roller, and the convex section is provided with a plurality of grooves at positions spaced apart from each other in a longitudinal direction thereof, wherein each of the grooves extends in the conveyance direction of the conveyance roller to allow a portion of the sheets on which the elastic element is disposed, to be inserted therein.

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a rotary anvil comprising a face surface, a plurality of non-linear ridges defined by a first plurality of grooves in the face surface, and a plurality of projections in each of the plurality of non-linear ridges. Each projection of the plurality of projections comprises a contact surface having parallel facing surfaces and parallel end surfaces.

An elastic composite structure includes a plurality of tensioned elastic threads positioned between first and second web layers. A pattern of laminating bonds fuse the first and second web layers together within a deactivated zone of the elastic composite structure. A cut end of a first portion of a tensioned elastic thread and a cut end of a second portion of the tensioned elastic thread are positioned on opposing ends of the deactivated zone. A pattern of anchoring bonds fuses the first and second web layers together within an anchored zone bounding opposing ends of the deactivated zone. The anchored zone includes a first plurality of bonds that anchor the first portion of the tensioned elastic thread to the first and second web layers and a second plurality of bonds arranged that anchor the second portion of the tensioned elastic thread to the first and second web layers.

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a bonding unit configured to bond a first web layer to a second web layer via a bond pattern that includes at least one bond line having at least one pair of adjacent bonds. The bonding unit secures an elastic thread within a passage defined by the at least one pair of adjacent bonds. The passage has a cross-sectional area smaller than a cross-sectional area of the elastic thread in a non-tensioned state.

A multi-layer exercise mat including a first layer including an outer surface and an opposing inner surface, the opposing inner surface of the first layer including a first array of three-dimensional features integral with the first layer; and a second layer including an outer surface and an opposing inner surface, the opposing inner surface of the second layer including a second array of three-dimensional features integral with the second layer. The first and second arrays of three-dimensional features are configured to grip each other to removably secure the inner surface of the first layer to the inner surface of the second layer.
