Thalmann TC Double Folder

Thalmann TC Double Metal Folder Machine - CIDAN Machinery Americas

The Thalmann TC metal double folder is often affectionately and respectfully referred to as “Big Mama” – due in large part to its solid construction. Of the 11,564 hand-crafted, high-quality parts that make up this double folder, the five 2” (50 mm) torsion drive shafts on the folding and upper beam movement give this machine its reputation of accuracy and longevity. Like the TD, the accuracy of the “Big Mama” is derived from the rotary encoders application directly on the torsion shaft. The torsion drive shafts completely eradicate the “twisting” that generally occurs over time. That means the TC metal double folder will produce a 60-bend part with an incredible end to end deviation of .070” (2 mm)!
