Abstract
A heat shrinkable wrap-around sleeve comprises a heat shrinkable sheet with a heat stable strip welded on one end. The free end of the heat stable strip is overlapped on the outer side of the opposite end of the sheet and welded thereto by heating applied directly on the outer side. This allows a good quality welded connection to be formed without requiring the use of hold-down adhesives. The sleeve can be manufactured using induction welding or more preferably by heated wedged welding.
