Abstract
Abstract The disclosure relates to a machine for making a plastic covering on a rigid base article which in the illustrated form comprises a glass bottle and a conforming shrunken plastic covering thereon. The plastic is fed in oriented sheet form to the turret apparatus, cut into lengths and wrapped and seamed on successive mandrels as sleeves. Bottles are simultaneously processed to preheat condition and indexed over the sleeves, the latter telescopically assembled on the rigid base article, i.e., the bottle, and the combination carried to a heat tunnel. The plastic sleeve shrinks into snug surface fit on the adjacent surface portion of the rigid base article. The bottle is preheated in one of two embodiments by: (1) a preheat tunnel on the machine which raises the bottles from room temperature to about 220*F, or (2) the preheat is carried over as latent heat in the glass bottle from the annealing lehr, a part of the bottle manufacturing process. The machine includes novel subassemblies comprised of (1) a bottle chuck and loading station for assuring proper loading of the bottles on the machine, (2) bottle handling, (3) plastic strip handling and feed mechanism for placing oriented cut lengths onto mandrels of the turret, (4) the turret for making seamed sleeves in succession and feeding them onto registered bottles carried by the bottle handling apparatus, and (5) unloading device for transfer of the covered bottles to a conveyor and with said transfer smoothening the bottom surface of the covering on the bottle.

Claim 2
Dependent Claim
220 words
Container handling apparatus comprising endless conveyor means including a conveyor frame and conveying elements supported by said frame for movement along an endless path, a plurality of container-handling chucks, each of said chucks having a housing, means mounting said housing on said conveying elements for movement therewith in said endless path, said mounting means also slidably connecting each chuck housing to said conveying elements for sliding movement normal to said endless path, guide means on said frame engageable with each said housing controlling the position thereof on said conveying elements during movement along said endless path, a rod depending from said housing with its axis normal to said path, plural rockable chuck elements pivotally connected on said housing depending in a direction normal to said path, link means, means pivotally connecting the link means to said rod and each of said chuck elements for rocking movement of said elements to and from a container gripping position whereat said chuck elements are cooperable to grip and support a container in axiaL upright position and rod operating means comprising resilient means in said housing engaging said rod normally urging the latter in one axial direction, and means on said frame engageable with said rods during movement at selected locations along said endless path for axially moving the rod in the other direction.
Claim 3
Dependent Claim
