METHOD OF APPLYING PLASTIC LABELS ON GLASS CONTAINERS

摘要

The disclosure relates to assembling thermoplastic sleeve coverings on rigid glass containers or bottles and heat-shrinking the plastic covering on the container. The plastic is fed from a web of material to a mandrelcarrying turret apparatus where it is cut into lengths and wrapped and seamed on successive mandrels,thereby forming sleeves. The bottles which arrive on a conveyor are successively moved and positioned over the sleeveforming mandrels and the sleeves are telescopically assembled onto the blass bottles. The bottles are then rotated about their axes and moved through a semicircular heated zone to shrink the sleeves into snug engagement with the surface of the glass bottle. After assembly and shrinking is complete, the bottles are released to an outfeed conveyor completing the process.
