Abstract: The invention relates to a bobbin carrier for receiving a bobbin which is set up for unwinding a strand material, wherein the bobbin carrier is provided for use in a braiding, winding or spiraling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier has a tensile-force measuring device for measuring the tensile force of the strand material unwound from the bobbin and has a first data transfer device for transferring data. According to the invention, the first data transfer device is set up to transfer measured tensile force values to a second data transfer device arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material can be detected early at the individual bobbin carriers.
