  • Patent number: 11149365
    Abstract: The present invention relates to a braiding machine and a method for controlling a braiding machine of this kind. An exemplary embodiment of the braiding machine has a plurality of braided-material carriers, a drive and a control device. The plurality of braided-material carriers are arranged around a common braiding centre of the braiding machine and are each designed to carry a braided material that is to be braided in the common braiding centre. The drive is designed to drive the plurality of braided-material carriers such that they move around the common braiding centre. The control device is designed to control the drive such that a centrifugal force acting on at least one of the braided-material carriers remains nearly constant.
