摘要：A method and apparatus for fusing adjacent surfaces of a pair of separatebodies made from thermoplastic, fusible material in which a heating device having a pairof mutually moveable parts is employed, each moveable part defining a heating surfacethat may be heated by heating means, there being pressure sensing means arrangedbetween the mutually moveable parts of the heating device whereby the so-called bead-up pressure may be measured and controlled independently of the varying dragpressure, the heating device being arranged between opposite ends of the bodies ortubes to be fused, the body surfaces being forced into abutting engagement with theheated opposite surfaces of the heating device, the heating device being removed fromthe heated surfaces of the bodies when the heated bodies are heated to the desiredegree, the heated bodies then being forced into mutual engagement to cause fusion ofthe bodies to one another.
