Linear movement of the tool assembly towards the rack (10) engages the die plate (324) against the rack (10) and punches the punches (322) through the cutting holes of the die plate (324) to punch a plurality of sealing sections from the foil sheet (131) and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes (20) in the rack (10).

Provided are a joining structure, a joining method, an exterior body for a wire harness, and a wire harness capable of firmly joining members having different physical properties while reducing the thickness of a joint part. The joining structure 10 joins a first member 1 made of a first resin and a second member 2 made of a second resin, wherein: the second resin has physical properties having a higher foaming ratio than the first resin; and a recessed joint part 3 is provided which reaches at least the inside of the first member 1 from the outer surface side of the second member in a state in which the first member 1 and the second member 2 are superimposed. Furthermore, a method for manufacturing the joining structure 10 comprises the steps of: superimposing a first member 1 made of a first resin and a second member 2 made of a second resin having physical properties having a higher foaming ratio than the first resin; and joining the first member 1 and the second member 2 by forming the recessed joint part 3 by pressing and hot-melting the second member 2 until the recessed joint part 3 reaches at least the inside of the first member 1 from the outer surface side of the second member 2.

A method and/or a machine is for tabbing a free end on a roll of sheet material. Converting a master roll of sheet material to the roll of sheet material and winding a first roll of sheet material onto a spindle at a winding position. Tabbing the free end of the roll of sheet material at a tabbing position. Where a tabber carrying a joiner are both in an initial position away from the first roll of sheet material, moving the tabber to a second position adjacent the roll of sheet material, moving the joiner into an engagement position where the joiner is engaged with the free end of the roll of sheet material. The joiner creates a tab with a combination of mechanical entanglement and heat welding. Returning the tabber and joiner to the initial positions. Doffing the tabbed roll of sheet material. The roll produced by the foregoing.

A method of anchoring a connector in a first object, wherein the first object is a lightweight building element having a first outer building layer and an interlining layer, and wherein the connector includes thermoplastic material in a solid state. The method includes: bringing a coupling surface portion of the connector into contact with an attachment location of the first outer building layer; displacing a portion of the first outer building layer at the attachment location with respect to the interlining layer by applying a first pressing force to the first outer building layer and thereby piercing the first outer building layer; applying a second pressing force to the connector and transferring energy to the connector until a flow portion of the thermoplastic material has liquefied and flown to interpenetrate structures of the interlining layer; and stopping the energy transfer and allowing the flow portion to re-solidify.

High-frequency welding method for welding an accessory to a substrate by high-frequency welding machinery which includes a female mold, having a cavity formed by a profile having substantially the same shape and dimensions as the accessory, and a male mold, having a relief formed by a profile having substantially the same shape and dimensions as the accessory. The method includes: mounting the female mold on a movable upper plate of the machinery and the male mold on a fixed lower plate of the machinery, or vice versa, such that the profile of the cavity is aligned in a closure direction of the molds with the profile of the relief. The method further includes: positioning the accessory on the relief or in the cavity; positioning the substrate above the accessory; moving the upper plate towards the lower plate; supplying high-frequency welding energy to the upper plate and/or to the lower plate.

Described is a ultrasonic welding of laminates, more particular to the use of ultrasonic energy to create stable perforations in a laminate, in particular a laminate that includes a silicone gel. Specifically, a perforation element is provided, that is optionally part of array of perforation elements, which perforation element or array of perforation elements is advantageously used in an ultrasonic welding device and in a process for continuously introducing perforations into a laminate.

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element (30) having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

A method of joining first and second layers of material according to the principles of the present disclosure includes applying a layer of adhesive between the first and second layers and allowing the adhesive layer to at least partially cure. The method further includes piercing the first layer with a headless end of a rivet after the adhesive layer is cured, deforming the second layer with the headless end of the rivet, and bending the headless end of the rivet radially outward.

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.

In a welded film laminate 1, a second protective layer 14 of a first film substrate 2 and a third protective layer 22 of a second film substrate 3 are welded and fixed to each other by an adhesive layer melted out from at least one of a first adhesive layer 11 to a fourth adhesive layer 27 via a first melted penetration portion 6a of the second protective layer 14 and/or a second melted penetration portion 6b of the third protective layer 22. A welding fixed portion 6c is surrounded in a plan view by a first welded portion 33 in which the first adhesive layer 11 and a second adhesive layer 15 of the first film substrate 2 are welded to each other and/or a second welded portion 35 in which a third adhesive layer 23 and the fourth adhesive layer 27 of the second film substrate 3 are welded to each other.
