Abstract
An industrial fabric, belt or sleeve and a method of making the fabric, belt or sleeve are disclosed. The industrial fabric, belt or sleeve is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, and joining the adjoining sides of the strips of material using ultrasonic welding or laser welding techniques. The fabric, belt or sleeve may then be perforated using a suitable technique to make it permeable to air and/or water.
