Abstract

Transfer devices are disclosed. At least one transfer device includes a housing, a supply roll rotatably mounted to the housing, a take-up roll rotatably mounted to the housing, and an application head. The supply roll has a wound supply of liner wound thereon, and the liner has an adhesive carrying surface with an adhesive provided thereon. The take-up roll has at least an end portion of the liner connected thereto such that rotation of the take-up roll in a take-up direction winds portions of the liner unwound from the supply roll onto the take-up roll. The application head includes a plurality of rollers that are rotatable about substantially parallel axes spaced apart from one another, and a closed-loop belt that is trained about the plurality of rollers to provide a transfer surface facing outwardly of the device. The rotation of the rollers enables the belt to travel around the rollers.
