Abstract

Hollow articles made by bonding plastic sheets together with a pattern of weld lines, heating the assembled panels to soften the material and then inflating the internal cavities between the weld lineds to the size required. Pref. the components layers are of crosslinkable polyethylene contg. peroxides etc; the layers are bonded by continuous and interrupted longitudinal and transverse welds which define a continuous series of panels which may be inflated and then sepd. to make e.g., individual radiators for circulating central fluids. Inflation is effected by hollow needles which pierce through or between the layers, pref. within a temporary casing which limits expansion in at least one direction.
