Strip/foil winding machine BWM 150 / 250 / 400 / 500 / 600 SPS
General information about our strip/foil winding machines
We develop and construct strip and foil winding machines (System Calotron®), which are internationally sought in the electrical engineering, especially in transformer and inductor construction, mainly due to their compactness, high performance and reliability.
Our machines use the latest high-tech control system, have a very high quality of winding and reduce machine maintenance to a minimum. There are various configurations possible which allow a wide range of transformer sizes and number of strips as required.
Various modifications, automatic functions and processes can be added to our strip/foil winding machines according to your requirements
