A method of making a joint for a structure comprises forming a thermoplastic filler, applying an uncured first thermoset layer into direct contact with the thermoplastic filler, applying an uncured second thermoset layer into direct contact with the thermoplastic filler, and applying an uncured third thermoset layer into direct contact with the thermoplastic filler. The method additionally comprises curing the uncured first thermoset layer, the uncured second thermoset layer, and the uncured third thermoset layer at a temperature below a melting temperature of the thermoplastic material to form a cured first thermoset layer, a cured second thermoset layer, and a cured third thermoset layer and bonding together the cured first thermoset layer, the cured second thermoset layer, the cured third thermoset layer, and the thermoplastic filler.

Methods for applying high shrink wrap labels to a shaped article are disclosed. The leading edge of the label is bonded to the article. A seaming agent is applied, and the label is wrapped around the article. The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa.sup.1/2 or within 4.4 calories.sup.1/2.Math.cm.sup.3/2 of the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60 C. Articles including such affixed high shrink wrap labels are also disclosed.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

A composite radius filler material is provided. The composite radius filler includes a resin, a first group of fibers dispersed within the resin, and a second group of fibers dispersed within the resin. The first group of fibers has a first length configured to facilitate orientation in a longitudinal direction. The second group of fibers has a second length that is shorter than the first length, with the second group of fibers configured to facilitate random orientation in a transverse direction.

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance a.sub.1 of 0.01 to 0.12; a second resin member which has an absorbance a.sub.2 of 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance a.sub.3 of 0.2 to 3.8, and the absorbances a.sub.2, a.sub.3 exhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.

A binding machine comprising: a feeding device for feeding a binding element (3) in the form of a wire or strap in a loop around one or more objects to be bound and subsequently retracting the binding element to draw it tightly around said objects; and a laser welding device for forming a welded joint between a section at the leading end of the binding element and an adjoining section at the trailing end of the part (3a) of the binding element fed in a loop around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device is configured to apply an identification marking on an outer surface of the binding element by means of a laser beam (14) emitted from a laser welding head of the laser welding device.

A bonded structure includes a first fiber part (12) and a second fiber part (14) arranged between a first member (10) and a second member (20). The first fiber part (12) and the second fiber part (14) are bonded so as to connect the first member (10) and the second member (20) to each other. The first fiber part (12) and the second fiber part (14) are arranged so that the fibers constituting the first fiber part (12) and the second fiber part (14) are oriented in a direction from the first member (10) toward the second member (20).
