Abstract:
1. A sampling system for extracting a sample from an end strip of a coil having wrapped layers of coiled formed elongated metal, comprising: a pair of generally parallel spaced driven rollers, for selective rotation of a coil about a coil central axis that is oriented parallel to the drive rollers; a thickness sensing gauge; a cutter in communication with the thickness sensing gauge, for selective alignment with a circumference of a metal coil that is oriented parallel to the driven rollers, the cutter having a cutter drive mechanism for selectively aligning and traversing the cutter along a least a portion of the coil end strip, the drive mechanism also advancing the cutter into the coil end strip based at least in part on strip thickness determined by the thickness sensing gauge so as to facilitate a separation of a coil sample from the coil while minimizing material deformation along the separation edge, wherein a cut channel is formed by the cutter having an angle θ relative to the coil central axis and a radial depth D into the strip thickness, leaving a thin neck of material at the base of the cut channel.
