A method for applying discrete components of a first substrate to a second substrate, the method comprising: rotating a drum about an axis of rotation, the drum having an outer circumferential surface; advancing the first substrate onto the outer circumferential surface of the drum; advancing the second substrate proximate to the outer circumferential surface of the drum, the second substrate having a first surface and a second surface, wherein the second surface comprises a target area; cutting the first substrate into discrete components on the outer circumferential surface of the drum, the discrete components having a first surface and an opposing second surface; continuously rotating a shaft of a motor at a variable angular velocity in a single direction, wherein the 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, 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; shifting a tamper member from a first position to a second position toward the second substrate and the outer circumferential surface of the drum as the shaft of the motor rotates in the first phase; displacing the second substrate such that the target area contacts the first surface of a discrete component on the drum; and shifting the tamper member from the second position to the first position as the shaft of the motor rotates in the second phase.
