An apparatus for applying a discrete component from a first substrate to a second substrate, the apparatus comprising: a drum having an outer circumferential surface; a cutter positioned to cut the first substrate on the outer circumferential surface of the drum into a plurality of discrete components; a conveyor for positioning the second substrate proximate to, but not in contact with, the outer circumferential surface of the drum; a programmable servo motor having a shaft, wherein the shaft continuously rotates at a variable angular velocity in a single direction, wherein the servo motor is configured to rotate the shaft in a first phase and a second phase, wherein the shaft is constrained to rotate from a first angular position to a second angular position in a first time in the first phase, and wherein the shaft is constrained to rotate from the second angular position to the first angular position in a second time in the second phase; and a tamper member associated with the shaft of the servo motor, wherein when the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component on the outer circumferential surface of the drum.
