The ultimate proof of quality and precision

The precision of “Big Mama” is derived from details such as rotary encoders directly on the torsion shaft. The torsion drive shafts eliminate the “twisting” that typically occurs over time. This means that the TC double folder will produce a part with 60 bends with an incredible final deviation of 2 mm!

This powerful machine is ready to handle the most challenging sheet metal processing projects. If you are looking for reliability and performance, the Thalmann TC double folder is the obvious choice. Take the step towards more efficient production with “Big Mama”!

Dynamic folding technology

Significant cost reductions can be achieved through faster bending processes. This is accomplished by having multiple machine axes in motion simultaneously. This innovation is designed to speed up the bending process without losing bending dynamics or accuracy. Dynamic folding technology is the cornerstone of increased productivity and enhanced capacity utilization in every bending operation. The technology with simultaneous movements ensures that stops in the bending process are minimized.

Synchronized drive shafts

Thalmann’s torsion shaft drive system produces bent parts with outstanding precision and reproducibility, unmatched and unique to Thalmann’s bending machines.

The synchronized power transmission is the core of Thalmann’s design concept and is comparable to the mechanical control in modern aircraft. The shafts’ movements are controlled by pulse counters with 5000 positions per revolution. No other bending machine can produce parts with the same accuracy that this technology offers.

Modular tool geometry

As standard, the machine is delivered with a straight lower beam with an angle of only 35°. This enables the production of profiles with a height/depth ratio of 3:4.

Maintenance and support via TeamViewer

The control system on a Thalmann machine can be remotely operated via TeamViewer. This allows you, as the user, to receive quick and efficient support for both applications and troubleshooting.

Fully automatic gripper system

To further increase the range of possible profile dimensions, a Thalmann TD can be equipped with grippers of different designs. Spring steel back gauge fingers are automatically activated when the minimum back gauge dimension with grippers is undershot.

Multi-Zone crowning of the bending beam

Precisely bent profiles with the same angle along the entire length are what you expect from a good long folding machine. The crowning system with graduated scales on all dials enables quick and accurate adjustments. A Thalmann machine is known for its high accuracy and minimal need for crowning, but when required, angle deviations are adjusted in no time with this innovation.

CNC control system with graphics and touchscreen

10-axis control system from Beckhoff with a 21.5” touchscreen in 16:9 format. The TD’s DS3000 control system can be operated in three modes: manual, semi-automatic, and automatic. In the control system, you can draw your profiles and view them in 3D. The sketch is converted into a bending program with optimal bending sequence calculation and simulation with collision control. It is also possible to load profiles in DXF format and from nuIT. The capability for offline programming on another computer is also included.

OPTION

Electrical slitter unit

Companies that apply additional cutting of folded sheets can integrate this operation on the THALMANN machine by adding a fully automated slitter unit. Investment in additional dedicated cutting or de-coiler units can often be avoided selecting this machine option.

In addition to achieving operational efficiencies trough the integration of folding and slitting in one operation, the folded metal sheets are less prone to damaging due to the reduction of manual handling. Scratches or bumps will be avoided with an electrical slitter unit.

On one and the same guiding system slitters and hemming/roll former heads are interchangeable. Both reductions in costs and investments are clear benefits and can be retrofitted on an existing THALMANN machine.

OPTION

Hemming and roll former unit

Modular and interchangeable hemming and roll forming units extend possibilities of forming sheet metals on a THALMANN machine. The hemming and roll forming unit can be mounted directly on the long folding machine. This unit is ideal for the production of calibrated highly accurate dimension panels and very tight hems.

offset folding beam geometry for increased flexibility and mor space in a thalmann td double folder

OPTION

Offset folding beam geometry

Architects, industrial designers, and facade designers are continuously looking for new profile geometries. With the addition of a cropped bending beam on a THALMANN folder, a wider range of dimensions of bended sheet metal parts can be produced. With this feature, THALMANN customers are able to expand their product portfolio and business for folded sheet metal parts.

OPTION

Double gripper unit

The ability to fold parts down to 200 mm can be achieved by selecting double gripper units on a THALMANN machine. Each existing single gripper can be made into a double gripper unit by “adding” an additional gripper.

A fully automatically activated spring loaded finger can be placed left or right or both sides of the double gripper unit.

OPTION

Automated tapered backgauge

The production of tapered parts is possible up to dimensional offset of +/- 250 mm. The positioning of the sheet metal is fully automated and multiple sheets can be manufactured in a tapered shape at the same time on one machine.

With the option of an automated tapered back-gauge, architects, roofers and engineers have the possibility to develop novel profile geometries and extend the scope of façade design.

OPTION

Multi-section gripper unit

Efficiencies, process flexibilities can be significantly enhanced by folding several sheets at the same time within one folding cycle.  The THALMANN machines can be custom equipped with fully automated multi section grippers that allows to handle and process several parts at the same time by one operator. For example 2 x 3 meter sheets can be folded simultaneously by one operator on a 6.4 meter Thalmann TD folder.

OPTION

Hardox

To improve durability and for heavy duty bending operations, HARDOX 400 steel bending beams will greatly enhance tool life as well as maintain accuracy of folded parts. The type of steel used to produce the beams is similar to the steel used for excavator shovels.

The extremely wear resistant Hardox beams will under normal operation last the lifetime of the machine and can be welded when damaged. Hardox beams on a THALMANN machine improves the stiffness and stability of the machine.

OPTION

Backgauge stop fingers

A wide range from 5 mm up to 1150 mm sheets can be folded with high accuracy with the installation of automated back gauge stop fingers on the THALMANN machines.

Back gauge stop-fingers will automatically be activated when the smallest possible grip zone is exceeded. The back gauge stop fingers will position the sheet metal in the right place.

OPTION

Interchangable tools

Mounted on the bending beam, a selection of different interchangeable beam extensions can greatly extend the scope of bends produced on a THALMANN machine.

OPTION

M-Guard remote access

For an efficient and extended scope of remote service, the optional M-Guard functionality is recommended. A secure and fast direct link between a THALMANN machine anywhere in the world and the service team in Switzerland is easily established with M-Guard.

M-Guard offers the possibility to perform software updates, software diagnostics and problem solving tasks. Up- to-date VPN technology ensures safe and fast data-transfer. Remote maintenance significantly reduces costs and time as no travel will be required to deliver this service.

hydraulic and oil cooling for a thalmann double folder for demanding work

OPTION

High-performance hyrdaulics with oil cooler – (hydraulic)

High-performance hydraulics with oil cooler. The unit with depressurized circulation principle guarantees low energy consumption and low noise level.

Double grippers

With the help of double grippers, it is possible to bend parts down to a length of 200 mm. A second gripper is easily placed next to one or more of the existing grippers.

Spring steel back gauge fingers, which are automatically activated, are advantageously placed on one or both sides of the double gripper.
