ABSTRACT:
Method and apparatus for applying heat shrinkable segments of sheet material to articles having a convex sector, e.g., for applying labels to containers. Each segment is attached at its leading end to the area of maximum diameter of the convex sector, preferably flattening such area and adhesively attaching the leading end of the segment to the flattened area, then spinning the article and wrapping the segment about it and attaching the trailing end to the container or to the leading end, then causing the so wrapped article to pass through a heating and shrinking station, spinning it while so doing and applying jets of hot air to the segment above and below the area of maximum diameter to shrink the segment onto the convex sector. Apparatus suitable for carrying out this procedure is also described.
