723,131. Labelling machines. ROSE BROS. (GAINSBOROUGH) Ltd. March 27, 1953 [Feb. 2, 1952 ; March 6, 1952], Nos. 2822/52 and 5811/52. Class 73. [Also in Group XVI] In a labelling machine the labels are separated in succession from a stack 13, Fig. 1, in a magazine 14 by a number of suction separators 12 (see Group XVI) which are carried by a common rotatable support 11, each label having gum applied thereto by a gumming-apparatus 16, and then being carried to a station at which a continuously-moving conveyer 17 moves a succession of round bottles 18, spaced by a rotating worm 19, into register with the separators. Each bottle is pressed against a separator 12 by a wheel 21 which rotates in a direction opposite to that of the support 11, so that the bottle is caused to roll on the label, the suction to the separator being cut off just prior to this rolling action. Further rolling pressure is applied to the labels on the bottles by a driven belt 22 mounted on pulleys 23, '24, the inner lap of the belt being spring-urged towards the bottles by a pressure-plate 26. The wheel 21 is mounted on a pivoted arm 68 urged by a spring 69 towards the conveyer 17. In a modification, shown in Fig. 7, the labels are applied to bottles with flat sides. The magazine 73, the rotatable support 71 carrying suction separators 72, and gumming-apparatus 74 are the same as before, but as rotatable worm 78, which spaces bottles 77 on a continuously-moving conveyer 76, is extended past the nip of a pressure wheel 79 so as positively to maintain the spacing of the bottles until registration has taken place. The wheel 79 is pivoted on a spring-urged arm, but is rotated in the same direction and at the same peripheral speed as the support 71, so that the label is transferred to the flat side of the bottle by the separator 12 rolling over that side. The wheel 79 comprises two spaced discs between which the worm 78 extends. Additional pressure on the labels on the bottles is applied by a driven resilient band 82, the inner lap of which is urged towards the bottles by a spring-loaded plate 83. In each case the gumming-apparatus 16 or 74 may be dispensed with, the labels having a prepared surface which is rendered adhesive by heat, and either heaters are incorporated in the separators 12 or 72, or the latter pass close to a source of heat, whereby the labels are rendered adhesive during their travel between the stack and the labelling station.
