The invention relates to a bobbin carrier 7 for receiving a bobbin 2 which is set up for unwinding a strand material I, wherein the bobbin carrier 7 is provided for use in a braiding, winding or spiralling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier 7 has a tensile-force measuring device 3 for measuring the tensile force of the strand material I unwound from the bobbin 2 and has a first data transfer device 4 for transferring data. According to the invention, the first data transfer device 4 is set up to transfer measured tensile force values to a second data transfer device 5 arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material I can be detected early at the individual bobbin carriers 7. The tensile force can be kept largely constant by the transfer of setpoint tensile force values from the second data transfer device 5 to the first data transfer device 4 and by a suitable control or regulation device 8 at the bobbin carrier 7.

Systems and methods are provided for braiding Metal Matrix composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.

The present invention relates to a switch for sorting, deflecting, and supplying ferromagnetic elements. Here, the switch comprises at least two electromagnets, which are embodied curved or circular. The magnets may be installed fixed in the switch, on the one hand, or supported on an axis, on the other hand. The ferromagnetic elements are moved by a conveying element through the switches. Advantageously the switch can also be used to control bobbins in a braiding machine. Here, the bobbin can be transferred to another impeller. This way new options are generated with regard to flexibility of braids. Further, this invention offers a considerable reduction of braiding time in case of complex braids.

An automatic circumferential insertion apparatus and method for a complex rotary preform. The apparatus includes a double-hinge yarn carrier and a U-shaped bracket. Two ends of the double-hinge yarn carrier are respectively provided with a cylindrical hinge structure. One cylindrical hinge structure is in revolute pair connection with an outer clamping buckle at one end of the U-shaped bracket, and the other cylindrical hinge structure is in revolute pair connection with an inner clamping buckle at the other end of the U-shaped bracket. Two sides of the U-shaped bracket are provided with an electromagnet, respectively. The outer clamping buckle is provided with a pin, which is controlled by trigging, and is triggered simultaneously with the electromagnet at the side where the outer clamping buckle is arranged.

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.
