Abstract
Abstract A method of welding applicable to a packing machine for use in strapping the package with a thermoplastic band, which employs an apparatus comprising; a slide plate supporting the overlap portions of the plastic band to be welded; a heat plate which is disposed parallel to the direction of strain of the strapping band and is devised to melt the overlap portions of the plastic band after its advance with the retreat of said slide plate; and a press bar which supports said plastic band at the time of melting and presses the melted overlap portion of said plastic band against the slide plate after the retreat of the heat plate to thereby weld them together.
