About us

Founded in 1894 by Carl Keller, KELLER is dedicated to the development and manufacture of machines and systems for brick production.

The process technology of the dryers used in brick factories is also used in other areas of industrialization.

In the 1960s, KELLER took over the production of wood skiving machines, which formed the basis for the development of film skiving machines (PTFE) and have been continuously further developed to this day.

KELLER is certified according to ISO with regard to quality, environment and energy and places high importance on this. For the customers, this means having a partner who follows rules in achieving these important goals and who cares for future generations.

Products & Services

KELLER film skiving machines skive PTFE and other plastics with comparable properties.

The steadily increasing demand for high-tech products ensures a worldwide increase in demand for precision films made of PTFE.

The machine is used in areas where high demands are placed on the skived films, such as in medical technology, the automotive industry, solar technology, and especially in communication technology for high-frequency lines and high-frequency antennas.

Here, extremely thin foils are required in compliance with the specified tight tolerances. In order to meet these requirements, special emphasis was placed on the rigidity of the machine during design. The rigidity allows an almost vibration-free skiving process. This ensures the skiving of ultra-thin films from 20 µm with a thickness tolerance of ± 3 µm, and this with skiving probe diameters of up to 800 mm and skiving probe lengths of up to 1600 mm.

KELLER also offers a film winding device and a knife grinding machine.

KELLER PTFE Film skiving machine

The machine owe their high precision and accuracy to the special bearings that ensure an absolutely vibration-free skiving process even with minimum film thicknesses of up to 0.020 mm.

Advantages are the highest precision with lowest tolerances, the minimum setting size of 0.001 mm, no mechanical adjustments required in the skive thickness range, the simple and clear operation and easy installation with the possibility of external commissioning.
