Extrusion: Better alignment of web-handling systems

A new tool facilitates the alignment of rollers, shafts, and web-handling systems. The Roll Adjuster is said to be easy to set up by simply placing it onto the top of a master roller, drive shaft, or idler, and it is held in place by a pair of V-legs or adaptable mounts. A fine-adjustment screw is turned until the bubble level is centered in its glass vial. The unit’s digital micrometer is then zeroed by pressing a small button on the front to capture the digital position of this first roll or shaft. The unit is then placed on top of the next available roller and the fine-adjustment screw turned until the bubble level is centered. The vertical alignment of this second roller is shown digitally, either in inches or millimeters, allowing for better adjustment or selection of new shims.
