An apparatus and method for effecting an operation on at least one moving substrate web is disclosed. The apparatus comprises a rotatable bonding roll that is located adjacent the substrate web and configured to rotate about a bonding axis. A rotatable anvil roll has an anvil surface and is configured to rotate about an anvil axis to press the substrate web against an outer peripheral bonding surface of the bonding roll thereby bonding the substrate web. At least three support wheels are configured to contact the bonding surface of the bonding roll and to hold the bonding roll in a substantially fixed position.

[ What is claimed is:] [1.]1. A method for effecting an operation on at least one moving substrate web comprising the steps of:a) supplying said at least one moving substrate web along a substrate path;b) providing a rotatable function roll adjacent said substrate path which rotates about a function axis and includes an outer peripheral surface upon which said substrate web travels;c) contacting said outer peripheral surface of said function roll with at least three supporting surfaces to maintain said function roll in a substantially fixed position in use; andd) providing a rotatable anvil roll adjacent said substrate path which rotates about an anvil axis and presses said substrate web against said outer peripheral surface of said function roll thereby effecting said operation on said substrate web.
