摘要

A method and apparatus for receiving discrete parts travelling at a first speed and apply the parts to a substrate web travelling at a second speed includes at least one rotatable transferring mechanism, a driving mechanism and at least one driven mechanism. The rotatable transferring mechanism is connected to an output shaft and moves along an orbital path through a receiving zone where the parts are received and an application zone where the parts are applied to the substrate web. The driving mechanism utilizes at least one rotatable noncircular drive gear connected to an input shaft to transmit rotational energy to the driven mechanism. The driven mechanism utilizes at least one rotatable noncircular driven gear connected to the output shaft or to a jackshaft to accept the rotational energy from the driving mechanism and transmit the energy to the transferring mechanism. The input shaft and output shaft or, in the alternative, jackshaft are offset such that the noncircular drive gear is configured to engage and rotate the noncircular driven gear which, in turn, rotates the rotatable transferring mechanism.
