Improvements to an automatic cold glue labeling machine having a label magazine, a rotary gripper cylinder for applying labels to containers, and a label transfer mechanism for transferring labels from the magazine to the rotary gripper cylinder. The transfer mechanism comprises a series of rotary glue pallets and a rotating glue pallet carrier on which the glue pallets orbit past the magazine to sequentially roll over the foremost label in the magazine to pick said foremost label out of the magazine and orbit past the rotary gripper cylinder whose finger assembly grasps and transfers the label thereto. The adhesive transfer surface of said glue pallets smoothly applies clear drying, high wet tack adhesives to film labels, and the modified profile of the gripping surfaces of the gripper cylinder finger and anvil assemblies reduces or eliminates finger marks on said label. An elastomer foam adhesive transfer face for each glue pallet and matched pairs of rounded convex-concave finger-anvil profiles for each finger-anvil assembly on said gripper cylinder. A heater apparatus also is disclosed.
