Abstract
An apparatus and method for separating welded multi-layered samples has a slotted engine-driven spindle that twists and pulls a layer from the sample, breaking the welds as the layer winds around the spindle. The sample is held between two clamps and a tensioning cylinder pulls a movable first clamp against the second stationery clamp. Sensors may sense the force required to break the welds and the data may be stored and analyzed in a computer.
