A multiple stage web processor including a tensioning stage and a gluing stage. The tensioning stage includes an air bag which generates a normal for ce applied against the web material. Web material tension may be altered with a change in air bag pressure. The gluing stage includes an adhesive applicator and provides an adhesive along a portion of the web material surface and als o applies a second normal force and tension to the web material. Together the tensioning stage and the gluing stage provide a controlled tension to the we b material as the web material is drawn through the apparatus and wrapped arou nd a tube-forming mandrel. The web processor may include a lubrication stage applying a lubricant to the web material surface. A method of forming a core from a web material with a web processor is disclosed.
