Apparatus and method of applying labels which includes providing (a) an applicator cylinder and a drive for rotating the applicator cylinder and (b) a source of discrete lengths of label material, traveling the lengths with the applicator cylinder, applying an electrostatic charge to the discrete lengths, advancing a carrier for sequentially receiving the discrete lengths from the applicator cylinder at a point of application, equipping one of the carrier and discrete lengths with an adhesive having an initial tack, and controlling the attraction of the discrete lengths to the applicator cylinder adjacent the point of application.

[ I claim:] [1.] A method of handling discrete lengths of material having a first and second side from a source of said material, and transferring said discrete lengths to a carrier, at least a portion of one of said first side of said material and carrier being coated with an adhesive having an initial tack, comprising:transporting said discrete lengths of said material in spaced relation on the surface of a rotating applicator cylinder with said second side of said discrete lengths contacting said surface of said applicator cylinder,applying an electrostatic charge to said discrete lengths to adhere said discrete lengths to said surface of applicator cylinder;advancing said carrier for sequentially receiving said discrete lengths from said applicator cylinder at a transfer location; andcontrolling the intensity of said electrostatic charge on said discrete lengths while said discrete lengths are adhered to said applicator cylinder under electrostatic attraction by applying a controlled voltage to a plurality of charge bars moving said discrete lengths to said transfer location, thereby controlling said electrostatic attraction of said discrete lengths to said applicator cylinder during said transporting step to permit said initial tack to transfer said discrete lengths from said applicator cylinder onto said carrier.
