Abstract: Many types of stabilized lock-seam tubing are provided, as well as devices, apparatus and methods for producing such stabilized tubing. Advantageously, pinch-locked tubing according to the invention, which comprise interlocking, spaced pinched deformations of the lock-seam, greatly resists side-slip and other shape deformations, including those typically produced by cutting the tubing, and by ovalizing it. Many permutations of lock-seam pinching rollers and related devices for producing stabilized lock-seam tubing are provided. Pinch roller assemblies of the invention are suitable for use with conventional machines as well as machines adapted specifically for them. Apparatus of the invention are suitable producing helically wound or straight lock-seam tubing.
