Abstract:
An apparatus, method, in-line press, and cassette for conditioning a substrate for subsequent processing, the apparatus comprising: an ultrasonic energy device with an ultrasonic horn having a contact surface; a rotatable cylinder having a raised profile with a linear or curvilinear pattern, the rotatable cylinder disposed adjacent the horn, but on an opposite side from the substrate; wherein the substrate is squeezed between the contact surface of the ultrasonic horn and the pattern on the rotatable cylinder to thereby apply heat and pressure during operation of the ultrasonic energy device to create a linear or curvilinear indentation in a surface of the substrate.
