ABSTRACT:
Disclosed is web handling apparatus 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 pilferproof 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 end and over the closure of a bottle of 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. Then the bottles are carried through a device for heating the label sufficiently to shrink it to final form.
