ABSTRACT:
Apparatus for guiding bottles along the surface of a rotating vacuum drum which holds plastic shrink labels until an individual label is rolled about the circumference of the bottle to form an overlapped seam. The bottles are of the style that have tapering shoulder and rounded heel joined by a cylindrical side wall. The rotational orientation of the bottle and label is maintained during roll-on of the label from the drum by a primary roll-on pad and the bottle with the label thereon is passed to an generally linear, secondary roll-on pad with the sleeve label bearing bottle moved along the secondary pad by a horizontally driven, vertically oriented belt. The secondary pad at locations along its length is provided with resilient vertically extending, contoured pads which also extend outward beyond the surface of the secondary pads so as to contact the formed overlap seam of the label to press the seam against the underlying bottle. The resilient pads have a contour which is generally the same as the shape of the bottle including the heel and shoulder to assure that the seam will withstand the stress of heat shrinking of the label about the bottle heel and shoulder portions.
