Method or applying heat shrinkable segments of material ( ) (e.g., labels or ornamental bands) to articles ( ) (e.g., containers or ornaments) which have convex surfaces. The segment ( ) is attached at both ends by adhesive to the convex surface ( ) (or the trailing end of the segment ( ) may be lapped over and adhesively attached to the leading end of the segment ( ). The adhesive attachments are confined to a narrow sector, e.g., the sector of widest diameter, or a circumference of a sphere, leaving major portions of the segment ( ) on either side of such narrow sector unattached. These major portions are then heat shrunk onto the convex surfaces ( ).

Method of labeling articles having convex surfaces

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.

Method of labeling containers with convex surfaces

A labeling machine employing a turrent with pairs of axially aligned chucks which are rotatable about their common axis, means to move each pair of chucks farther apart for entry and exit of containers; such machine also having a vacuum drum rotatable about an axis parallel to the turret axis and a roll on pad spaced from and concentric to the vacuum drum to confine each container released by the turret and to roll each container on the cylinder surface of the vacuum drum. The roll on pad may have a rearward (downstream) extension to contact the container and rotate them.
