Thalmann TZ Long Folder

Torsion shaft technology

Thalmann’s unique drive shaft/torsion shaft is a mechanical control system synchronizing all mechanical axes using a massive steel shaft, comparable to the 4-wheel drive functionality of a car. This unique kinetic drive concept distributes power from all C-frames evenly over the clamp and folding beam. In addition, it maintains constant operation pressure over the entire bearing length.

Advantages of the torsion shaft:

• Extremely precise bending
• Direct encoder measuring
• Unrivaled angle and parallelism
• Ensures equal wear of parts resulting in an even fold for the lifetime of the machine

Curved upper beam

Thalmann long folders can be equipped with two different tool shapes for the upper clamping beam. A straight upper-beam tool is supplied as standard. A curved upper-beam tool, resembling a goat’s foot, can be optionally supplied.

This tool can be used to shape metal parts with a side ratio of just 1:2 (e.g. a ratio of 35 mm (1.37”) height to 70 mm (2.75”) depth).

Advantages of the curved upper beam:

• Space around bent part is increased to a total of 275°
• Significantly more flexibility during the folding process

Recessed Lower Beam

Additional free space and flexibility are provided by the newly designed clamping beams andoffset folding beam. With Thalmann’s modular tool geometry, the folding beam is offset, moved back to the folding line and set at a 15° angle. This increases the space around the bent part to a total of 275°, creating more flexibility during the folding process.

Advantages of the recessed lower beam:

• Additional folding space
• High-precision folding with folds as small as 0.59″ x 0.59″ (15mm x 15mm)
  

Vertical Force Drive

The Vertical Force Drive (VFD) is an exclusive design principle developed by Thalmann engineers used in the TZ and TC models. While conventional long folders use stands that work like oversized pliers to clamp material, Thalmann folders use stands that are formed in the shape of “rigid C-frames.” The vertically arranged clamping beam mounted on top of the C-frame creates a powerful, vertical pressing and clamping force.

Advantages of the Vertical Force Drive:

• Guarantees reliable clamping of sheet metal parts
• Applies even pressure on open or closed hems
• Ensures that folded parts are precisely positioned during processing
• Zero-point locking system eliminates risk of an overload
• Stable performance in industrial profile manufacturing
