A process and an apparatus for high speed manufacture of a composite sheet material, which includes a cylindrical cam-driven strand-traverse guide that can loop strands around pins projecting from a pair of advancing pin conveyors which can transfer the strands to the surface of a moving sheet, are provided. When the strands are elastic, the elastic composite sheet material made by this process and apparatus are useful in elastic components of disposable diapers, adult incontinence articles and other garments.

An apparatus, system, and process for making a sterile connection between two thermoplastic resin tubes is disclosed. The tubes are cut by a hot cutting means so as to form a molten interface between the tubes and the cutting means. The tubes are aligned with each other and slid off an edge of the cutting means while being urged together. As the thermoplastic resin cools a sterile splice is formed. The apparatus is controlled to provide precise timing of the above events and includes safeguards to ensure sterility is maintained.

An improved collet type bobbin chuck which uses mating tapered surfaces to produce radial gripping of the bobbins without dependence on centrifugal force. Air pressure supplied to the chuck is used to release the bobbin and movable seals within the chuck are used for containing or releasing air as the chuck goes from a bobbin releasing to a bobbin gripping mode, respectively.

An electric heating element for sterilely cutting and welding together a pair of thermoplastic tubes transversely of the axis of each tube includes as an outer layer a folded sheet of a metal, such as copper, aluminum, silver or gold, having a thermal conductivity of at least about 173 watts/m. degree. K at a thickness of 0. 10 mm and a tensile yield strength of at least 34. times. 104 kPa at a 0. 10 mm thickness. A resistance heating element, preferably having a positive thermal coefficient of resistance (PTC), in the form of a resistor of stainless steel or the like is disposed inside the fold of the metal sheet and a layer of dielectric adhesive, such as an epoxy or acrylic adhesive, stable to about 260. degree. C. , is disposed between the inner surfaces of the metal sheet and the resistor to insulate the resistor from the folded sheet and bond the resulting structure together. The folded edge of the metal sheet forms the melting edge of the heating element.
