A composite fabric comprises perforated expanded low density polyethylene foam that is mechanically attached to two opposing facing layers, at least one of which outer facing layers is a non-woven material. The signal emitters are positioned adjacent a conveyor transporting bottles so as to direct signals to different cap target locators. The coated abrasive particles have an outer layer coating with highly tortuous surface comprising about 5 spikes and have a tortuosity of at least about 1. A metal layer is formed on the cathode conductive layer.
