Abstract

The edges of a pair of polybutylene sheets are sealed together by gripping the sheets adjacent their edges between clamping bars, heating the skirt projecting from the bars to form a bead weld on the edges of the sheets, and finally applying a surfactant fluid to the bead to rid it of its tacky surface. Heating is pref. applied by a low flame and the surfactant may be applied as a mist or falling curtain, or by dipping the bead into a bath. It may be necessary to dry the detackified bead. A non-tacky seal is obtd.
