Abstract
A method and apparatus for applying a label onto a substantially cylindrical article is disclosed. A thin layer, heat activated adhesive backed label is fed onto the surface of a rotating label transport drum so that the adhesive back faces outward from the drum. The adhesive is heated as the drum rotates so that the adhesive obtains a sufficient temperature to melt. Articles are conveyed into tangential spinning engagement with the drum and into rotate engagement with the leading edge of the label as the label moves into the article wrapping position so that the label wraps about the article and adheres thereto. The articles can include crayons which are somewhat tapered along their length. The articles are conveyed at a skewed angle so that the label wraps about the tapered crayon with end-to-end label alignment thereof. The crayon is conveyed onto the drum surface so that the wider "butt" end of the crayon engages the leading edge of the label before the more narrow and of the crayon engages the label.
