Abstract
A braiding method comprising 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 braiding machine having a track along which bobbin carriers are moved, the braiding machine comprising:
- a substantially linear transfer section having a first end and a second end,
- two substantially semicircular sections connected to the first end of the transfer section,
- two substantially semicircular sections connected to the second end of the transfer section, and
- collision prevention means for preventing collision of bobbin carriers travelling in substantially opposite directions in the transfer section, the collision prevention means comprising a substantially circular sidetrack connected to the transfer section onto which sidetrack the bobbin carriers are shuntable.

A braiding method, comprising:
- providing a substantially linear transfer track section having a first end and a second end,
- connecting two substantially semicircular track sections to the first end of the transfer section,
- connecting two substantially semicircular track sections to the second end of the transfer section,
- connecting a substantially circular sidetrack to the transfer track section,
- providing bobbins having strands on bobbin carriers,
- moving the bobbin carriers along the track,
- drawing out the strands from the bobbins provided on the bobbin carriers,
- intertwining the drawn out strands to form a braid, and
- shunting at least one bobbin carrier moving in the transfer section onto the sidetrack to thereby prevent collision between the at least one bobbin carrier and another bobbin carrier moving in the transfer section in a direction substantially opposite to the at least one bobbin carrier.
