A method of assembling a first part made from a metal and a second part includes providing a first part comprising an assembly surface, and a second part comprising at least one through orifice. At least part of the second part is arranged on the assembly surface such that the orifice extends across from the assembly surface. A metal connecting part is positioned on the orifice to cover the orifice across from the assembly surface. The connecting part and/or the assembly surface are projected on one another to obtain high-speed plating and welding between the connecting part and the surface part.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

A split bus assembly is provided for a heat-sealing machine. The split bus assembly includes a clamp with first and second clamp segments that abut each other in face-to-face engagement. The engaging surfaces or inner walls of the clamp segments may be coated with a nonconductive material so that the clamp segments are electrically insulated with respect to each other. A tab terminal may be defined at each inner wall, constituting a zone of exposed conductive material which is configured to engage a conductive tab of a heat-seal band during use. Biasing members such as a silicone spring may be arranged in the tool to facilitate ejection of the heat-seal band during a removal procedure. The tool may be cooled by way of cooling fluid that flows through passages in the bus bars.

A heat-seal band system is provided with an air gap arrangement that facilitates heat tunability and corresponding balancing of heat distribution through a tab to band (tab/band) junction of a heat-seal band. The heat-seal band may be implemented as a closed-contour heat-seal band with a band that has a workpiece facing surface that directs heat toward a workpiece and an opposite surface from which a pair of conductive tabs extend. Tab covers engage at least portions of the tabs to establish air gaps with dimensions that influence energy transmissibility at the tab/band junction. The tab covers may be fixed such as those defined by portions of clamps that hold the tabs and/or variable such as those implemented as replaceable gap gauges of different dimensions. Selecting and mounting different gap gauges facilitates heat tunability through adjusting the air gap to help identify an acceptable amount of heating uniformity about an entire workpiece facing surface of the heat-seal band.

An apparatus (10) for vacuumizing and sealing a package (322) includes a plurality of platens (12) and vacuum chambers (14), each chamber (14) adapted to mate with a dedicated one of the platens (12); a conveying system (16) for conveying the platens (12) and chambers (14) along a generally angular path having a single axis of rotation (18); an automated loading assembly (20) having a linear component (22c) and configured to load a package (322) onto each of the platens (12); an automated unloading assembly (26) having a linear portion and configured to unload a vacuumized, sealed package (322) from each loaded platen (12) onto an outfeed conveyor (30); and a vacuumizing/sealing system configured to cause relative movement of each chamber (14)/platen (12) pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package (322) and effect vacuumization and sealing of the package (322).

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.
