Two opposed programmable Tangent Formers using a combination feed form sequence will form a wide variety of three sided Furnace Wrappers. One traveling Tangent Former Head feeds and indexes the part into a fixed position Tangent Former Head. Using a combination of clamp, feed, and form cycles the two  ends are formed then sides are formed into a three sided wrap housing. Flange heights can vary form part without any changeovers or setups.

The Punch, Notch, and Rollformer automatically varied in width to match the blank width. A program was downloaded to sequence the notch and punch pattern along with the form sequence for the Tangent Former.  3 Sided Wrapper
