ABSTRACT:
A portable system provides a high-strength joint between two portions of radiant energy transmitting thermoplastic strap having an opaque radiant energy absorbing area on one surface thereof, wherein the strap portions are overlapped so that the opaque area is at the interface therebetween. The overlapped strap portions are clamped at spaced-apart locations so that at least one strap portion is fixed. An arcuate anvil is then moved against the strap portions between the clamp locations for urging the strap portions together and deflecting them, thereby placing the fixed strap portion under tension. Infrared energy is directed through a free, uncontacted, outer surface area of the tensioned strap portion and onto the opaque area for melting the adjacent strap surfaces to form a joint. The clamps and anvil are manually operated. A manually operable cutter is provided for severing the tensioned strap portion from its supply after formation of the joint.
