Description

An  important part of any seam evaluation is the actual teardown of the can seam to determine tightness or wrinkle rating. In the past, this job was often done with hand tools or with a seam lathe. The hand tool method is both difficult and time consuming, and frequently distorts the seam. The seam lathe is a large expensive piece of equipment which requires special training.
     The Waco Universal Can Stripper cuts the cover hook and separates it from the body hook without distortion. Moreover, it is faster, safer and easier than any other method available. The stripper pays for itself in labor savings alone in just a few months. Add the potential for loss of product caused by defective seam formation, and the purchase of a Waco Universal Can Stripper makes even more sense.

Operation
     Waco Universal Can Strippers may be used on round cans made of steel or aluminum. In operation, the can to be stripped is placed in the can holder assembly. As the cutter head is lowered onto the can, a switch is activated which automatically spins the cutter head around the top of the seam. The patented roller cutters engage the outer diameter of the seam and make a clean cut through the cover hook. The roller cutters continue downward, separating the cover hook without distortion. The cutting and stripping operation is done in one step and only takes 3 to 5 seconds.
     Due to the unique configuration of the roller cutters, only the cover hook is cut. The body hook and cover hook are in perfect condition for measurement or visual inspection. Seam defects such as pleats, puckers and wrinkles can be easily identified and examined. A special micrometer is available to measure the cover hook and body hook.

Design
     Waco Universal Can Strippers are ruggedly built for safe, quiet, benchtop operation. Models are available for most common can sizes. When ordering, the end diameter and can height must be specified so that the appropriate change parts are included.
     All beverage can models are supplied with a built-in seam saw for cutting a cross section through the can seam. These cross sections are then measured and evaluated for overlap, body hook and cover hook with the WACO VSM II Video Seam Monitor.
