An outer tube for a front fork having an FRP pipe body which is subjected to braiding processing using a braider, wherein the FRP pipe comprises a combination of braids interlacing with each other at an interlacing angle &#xb1;&#x3b8;&#xb0; with respect to a center axis of the pipe and warp fibers having an angle 0&#xb0; with respect to the pipe center axis, rigidity of the plurality of warp fibers disposed at positions in a circumferential direction of the pipe is varied depending upon the positions in the circumferential direction of the pipe, and bending rigidity of the FRP pipe in the longitudinal direction is varied in the circumferential direction of the pipe.

Outer tube for front fork

A braiding unit moving type braiding apparatus is capable of extremely efficiently braiding apparatus is capable of extremely efficiently braiding on a long mandrel having a curved portion. A braiding layer is formed around a mandrel using the braiding unit. The braiding apparatus includes a braiding unit mover which moves the braiding unit along an axis of the mandrel, and the braiding unit mover includes a drive source which is directly or indirectly provided in the braiding unit, and a first guide and/or a second guide which is aligned with the axis of the mandrel as viewed from above and/or the axis of the mandrel as viewed from the side.

Braiding unit moving type braiding apparatus

To prevent a long molding from bending during drying and hardening in a drying furnace after braiding. A pair of rotatable joints 2 and 3 are used as a stretching jig for a long braiding mandrel, the joints are connected to the respective ends of the mandrel, and a loading means 16 is used to stretch the mandrel via the joints to apply tension to it.

Stretching jig for braiding mandrel and method for forming long molding

A braider having a mandrel support member which is pivotable around a braiding point and linearly movable toward and away from the braiding point. Since control of the position of the mandrel is performed by pivotal motion around the braiding point and linear movement in a direction toward the braiding point, the mandrel can be moved to an arbitrary position without depending upon movement of the mandrel by a great distance in one direction.
