ABSTRACT:
The invention disclosed sets forth a method and machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web. The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats. Predecorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature. Such a label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam the overlap to make a sleeve. The sleeve is stripped onto the top neck and over the closure of a bottle at room temperature to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking the material onto a "cold" bottle.
The disclosure includes a novel machine for making the sleeve from a plastic web and placing it on the bottle. There is disclosed a combination of novel devices in the machine including a slitting device, pleating device, feed and winding device, hot air heating device for sealing the seam of a sleeve and for pressing the seam, and an article handling mechanism for indexing the bottles coaxially with a sleeve and transferring the sleeve over the bottle to label position at production rates. With the sleeves of shrinkable label material thusly placed, the bottles are carried through a device for heating the label sufficiently to shrink it to final form. There is also disclosed the step and means for treating the bottle with adhesive before transferring the label sleeve onto it, providing an adhesive bond between the neck of the bottle and the shrunken label sleeve which enhances the function of the pilfer-proof label.
