A method of applying a label to a container which includes an intermediate portion of the sidewall thereof which has an annular curved surface wherein the vertical height of the portion having a curved surface is a minor portion of the entire height of the container. A narrow rectangular label of shrinkable material is first provided with one or more longitudinally extending strips of adhesive extending intermediate the longitudinal edges of the label at the area of the label which is to contact the portion of greatest diameter on the curved portion of the container. The strip of adhesive material is shorter than the length of the label so that the adhesive material does not contact the overlapping edges of the label. An adhesive is applied to the trailing edge of the label only and the label is wrapped about the compound curved portion with the adhesive strip engaging the curved portion of the container at the area of greatest diameter. The edges of the label are overlapped and bonded and the overlapped label is then shrunk into position by moving the container and label through an oven. The curved portion of the container may have a compound curvature.

Method of applying a label to a container having a curved portion

A method and apparatus for forming a shrinkable sleeve of plastic material and applying it as a label to a glass or plastic container. The plastic is fed from a source, cut to successive lengths, wrapped about successive mandrels and sealed to form each sleeve. Thereafter each sleeve is transferred from the mandrel onto an overlying container. The mandrels are circumferentially positioned on a turret, and a combined heat seal bar and tucker bar is associated with each mandrel to bond the overlapping ends of the severed length of plastic material to one another. A stripper transfers each sleeve that has been so formed from a position on the mandrel axially onto an overlying aligned container while the path of the container overlies the respective mandrel for a portion of its movement by the turret.
