Apparatus for applying outside heads in the form of paperboard disks to the ends of wrapped paper rolls has platens provided with means, i.e., recesses, for accommodating protruding roll core ends in a manner to avoid interference of such protruding core ends with efficient, uniform application of the heads to the ends of the wrapped paper rolls. Means cooperate with the core end accommodating means for holding the heads on the platens until the heads have been applied to the roll ends. Such holding means desirably comprise an array of radiating channels dead ended adjacent to the core end accommodating means recess on each platen and communicating through ports adjacent the dead ends with a suction device, i.e., blower fan. |
