2.1 History of flat belts The industrial revolution In pre-industrial times, the forces of nature were harnessed using axles, gears and drive mechanisms like chains and ropes. Normally, a con­ nection was established between the generator and a single consumer: from the windmill vane to the grind­ stone, from the draft animal to the scoop wheel, from the water wheel to the forging hammer. This principle endured for thousands of years – until, completely independent of wind energy or hydropower, the steam engine offered such great mechanical power on demand that many consumers could be supplied...

Production building 1906. Each of the processing machines is driven by a central transmission shaft underneath the building’s ceiling. Siegling shapes flat belt development In 1919 Ernst Siegling founded a transmission belt factory in his name in Hanover and shortly thereafter began producing flat belts made of leather. At the start of the 1920s, he helped with the breakthrough of a new flat belt design: the upright chrome leather belt. Upright leather belts were con­ nected crossways to the direction of movement using rivet pins. This made the belt particularly robust, even and efficient. With...

2.1 History of flat belts However, the disadvantages of natural leather were still evident: leather stretches over time which means that the belts have to be shortened at regular intervals. On top of that, the belts were not particularly dimensionally stable and were sensitive to moisture. At the same time, industrial buyers were becoming more demanding in terms of their technical require­ ments. The advent of motors increas­ ingly suppressed energy distribution via transmissions and single drive tool machines became the norm. Flat belts were now in stiff com­ petition with other transmission...

Ernst Siegling died in 1954, whereupon his son Hellmut Siegling took over the company and successfully carried on the concept of the multi-layered flat belt. In addition to the tried and true polyamide band, a variety of other fabric tension members came into use. The chrome leather coating also underwent numerous changes. Diversification led to the creation of new products that have since become indispensable to a variety of industrial sectors. Even the development of a fabric-based plastic conveyor for internal materials flow (Transilon) in the 1960s, groundbreaking at the time, was based on...

2.1 History of flat belts In 1994, the Forbo Beteiligungs GmbH took over the shares previously owned by the family. The company continued on its path to globalism, adding new production and assembly sites in countries including China. Rigorous research and development work drove the development of flat belts that perfectly supported produc­ tion processes while performing their function as drive elements. Siegling Extremultus flat belts are prime exam­ ples of this, boasting outstanding grip for converting paper and cardboard (Grip Star™) as well as belts for electro­ static discharge (ESD) areas...

Flat belts today Today’s descendants of the old trans­ mission belts are high-tech products that contribute significantly when it comes to efficient and smooth opera­ tion in a wide variety of industrial drive and production processes. Their rapid evolution and the state of their devel­ opment today are evident in their impressive key data: Tensile strength The tensile strength increased from 30 N/mm2 for core leather belts to approx. 500 N/mm2 for flat belts with a polyamide tension member. Today, values of approx. 800 N/mm2 are easily achieved when polyester materials are used. This type of...
