ABSTRACT:
An adaptor core for rotatably mounting a coreless roll of labels or the like on the spindle of a labeling gun of the type designed to accept only cored rolls of labels. The adaptor core comprises a hollow generally cylindrical body of one-piece construction having a central circular opening therein, and a series of relatively thin resilient fingers formed integrally with the body and extending laterally outwardly therefrom at the periphery of the body. The core is placed in the central opening of a coreless roll of labels with the fingers engaging the roll and being sprung inwardly by the roll. The outward springing force exerted by the fingers against the roll is sufficient to secure the body in place relative to the roll with the opening in the body generally concentric with the opening in the roll for receiving the spindle of the labeling gun thereby to rotatably mount the adaptor core and roll on the spindle.
