ABSTRACT:
A marker applying device (50) for a substrate (14) having a plurality of markers (70) having magnetic material (74) in a backing (72) of the markers (70), and an adhesive (76) on a front surface (78) of the backing (72), a marker retainer (62) having a relative weak magnetic force at spaced locations (64) for releasably retaining the markers (70) at the spaced locations (64) in a configuration with the adhesive (76) facing outwardly from the retainer (62), an electromagnet (88) positioned with the substrate (14) being intermediate the electromagnet (88) and retainer (62), and the markers (70) being sequentially positioned by the retainer (62) in a configuration with the adhesive (76) facing the electromagnet (88) and substrate (14), and a device (CPU) for electrically pulsing the electromagnet (88) to produce a relatively strong magnetic force, such that the electromagnet (88) removes the markers (70) from the retainer (62) and deposits them onto the substrate (14) such that the adhesive (76) on the markers (70) retains the markers (70) on the substrate (14).
