Abstract:
1. A method for intermittently varying a speed of a portion of an advancing substrate, the method comprising the steps of: continuously advancing a substrate in a machine direction at a first speed; engaging the substrate with a first guide member; advancing the substrate from the first guide member to a second guide member, the second guide member being connected with a support member; engaging the substrate with the second guide member; rotating the support member at a first variable angular velocity such that the second guide member orbits around a center axis of the support member at a varying angular velocity as the support member rotates; advancing the substrate from the second guide member to a third guide member; engaging the substrate with the third guide member; advancing the substrate from the third guide member at a second speed, wherein the second speed is variable; advancing the substrate from the third guide member at the second speed to a processing station; applying an ultrasonic bond to the substrate at the processing station when the substrate is moving at the second speed; advancing the substrate at the second speed to a fourth guide member; engaging the substrate with the fourth guide member; advancing the substrate from the fourth guide member to a fifth guide member, the fifth guide member being connected with a second support member; engaging the substrate with the fifth guide member; and rotating the second support member at a second variable angular velocity such that the fifth guide member orbits around a second center axis of the second support member at a varying angular velocity as the second support member rotates, wherein the support member is operatively engaged with a first variable speed motor and the second support member is operatively engaged with a second variable speed motor.
