The present application relates to a kind of stent and stent weaving method, weaving method uses cylindrical clamp, cylindrical clamp is evenly divided into multiple rows along axial direction and evenly divided into multiple columns along circumferential direction, each row and each column intersection forms intersection, at least part of intersection is provided with the positioning pin for wire winding;Weaving method includes the following steps: the intersection with positioning pin is called weaving position, with one weaving position as starting point, make wire with V-shaped between two rows in the up and down bending movement, until weaving forms the stent of required length, and material passes all intersections;Wherein, all the inflection points of the V-shaped are located at the weaving position and wrap the positioning pin;If a positioning pin has two reverse V-shaped, the two reverse V-shaped are hooked with each other;In weaving process, wire is interlaced in the woven path up and down. Stent has the advantages of easy assembly, small shortening rate and good compliance.

To provide a method for yaw oscillation of a fiber unwinding bobbin that allows for miniaturization of the equipment. [Solution] The yaw oscillation method for a fiber unwinding bobbin uses a fiber unwinding bobbin having a cylindrical bobbin that is rotatable for unwinding, a pivot base that rotatably holds the bobbin and is pivotable, a pivot axis of the pivot base, a base part that fixes the pivot axis, a stopper for stopping the rotation, and a spring part for providing a reaction force, such as a spring, that assists in the return after rotation. The cylindrical bobbin is rotated in accordance with the movement of the fiber unwinding position toward the end of the cylindrical bobbin (b), and when the fiber unwinding position reaches the end of the cylindrical bobbin, the pivot reaction force spring and the rotation moment due to unwinding are balanced (c), and when the fiber unwinding position begins to return to the center of the cylindrical bobbin, the reaction force of the spring rotates the cylindrical bobbin in the opposite direction (d).
