A \u003cstrong\u003estretcher\u003c\/strong\u003e elongates the fiber by expanding it, creating a convex curve. Alternating between the two functions allows complex shapes to be achieved on thin sheet metal without wrinkles or tears.

Check the specific limits in the technical table for the Bernardo Foot-Operated Shrinker and Stretcher. Exceeding the limits causes damage to tools and irregular deformations on the workpiece.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between lever, foot-operated, and motorized versions?\u003c\/summary\u003e\n\u003cp\u003eThe \u003cstrong\u003elever version\u003c\/strong\u003e (Pro) is manual: the operator uses both hands to operate the lever, ideal for occasional work. The \u003cstrong\u003efoot-operated version\u003c\/strong\u003e (FD\/F) operates the machine with the foot, freeing both hands to hold and guide the workpiece – more convenient for repetitive tasks. The \u003cstrong\u003emotorized\u003c\/strong\u003e or electric version automates the complete cycle for series production.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo the jaws wear out?

Original Bernardo replacement jaws are available with 3–5 business days shipping.
