Abstract
A braiding apparatus and method for moving bobbin carriers along tracks connecting a plurality of braiding regions to braid cords or strands in a specific braiding region, in another braiding region or in all the braiding regions. The braid may be used as core structure for fiber-reinforced plastics.
Claims8
A fiber braiding device, comprising:
- a first braiding region provided with first tracks arranged in an open circle to form a flat braid,
- a second braiding region provided with second tracks arranged in a closed circle to form a tubular braid, the second braiding region in spaced relation to the first braiding region,
- transfer tracks for connecting the first and second braiding regions,
- a gathering guide defining a braiding point where cords or strands are collected and braided, the gathering guide shiftable between a position above the first braiding region and a position above the second braiding region, and
- shifting means for shifting the gathering guide from the position above the first region to a position above the second region.
2 more elements
A method of braiding cords or strands, the method comprising the steps of:
- providing tracks defining at least a first braiding region and a second braiding region,
- moving bobbin carriers along the tracks defining the first braiding region to form a first type of braid,
- transferring the bobbin carriers to the tracks defining the second region,
- moving the bobbin carriers along the tracks defining the second braiding region to form a second type of braid, and
- shifting a gathering guide from a position above the first braiding region to a position above the second braiding region.
