Abstract
A braider and a tube body in which braids are arranged on an outer peripheral surface of a mandrel uniformly even if the diameter of the mandrel is uneven. A braider 1 has bobbin carrier conveyance mechanisms 50A and 50B in which bobbin carriers 40A and 40B are conveyed from traveling tracks W1 and W2 to an outside of the traveling tracks W1 and W2 so as to stop winding of braids Y1 and Y2 onto a mandrel 2 and the bobbin carriers 40A and 40B are conveyed from the outside of the traveling tracks W1 and W2 to the traveling tracks W1 and W2 so as to start the winding of the braids Y1 and Y2 onto the mandrel 2.
Claims10
A braider wherein, while a mandrel is moved relatively to a support member in which a traveling track for a bobbin carrier is provided, the bobbin carrier travels along the traveling track so that braids spanned between the bobbin carrier and the mandrel are wound onto an outer peripheral surface of the mandrel, comprising:
- a bobbin carrier conveyance mechanism in which the bobbin carrier is conveyed from the traveling track to an outside of the traveling track so as to stop winding of the braids onto the mandrel and the bobbin carrier is conveyed from the outside of the traveling track onto the traveling track so as to start the winding of the braids onto the mandrel.
A tube body configured such that first braids and second braids, which are arranged spirally along an axial direction and slanted oppositely to each other with respect to an axis, are braided with each other so as to form a reinforcing fiber layer on an outer perimeter of a mandrel,
- wherein a total number of the first braids and the second braids existing in a section perpendicular to the axis at a first position in the axial direction is different from a total number of the first braids and the second braids existing in a section perpendicular to the axis at a second position, which is different from the first position, in the axial direction.
