Abstract
Abstract An apparatus and method for automatically stripping sheet material from a bobbin, measuring characteristics of the material and labelling the bobbin. The apparatus includes a delaminator pick-up device for securing a lamination layer of the material and picking-up the secured portion from the bobbin. A threading device threads the secured portion and contiguous portions of the material through a measurement device. The threaded material is engaged by an engaging device and passed through the measurement device. The measurement device measures characteristics of the material.
