Title:
POLYGONAL BOBBIN BODY, MANUFACTURING METHOD OF FIBER BUNDLE, AND BLOOD PURIFIER
Document Type and Number:
Japanese Patent JP2022108325
Kind Code:
A
Abstract:
To provide a polygonal bobbin body, regardless of a simple structure, highly precisely and highly densely reeling fibers therein and easily keeping the form of an acquired fiber bundle.SOLUTION: A polygonal bobbin body comprises a central part 110, a plurality of extension parts 120, a plurality of connection parts 130, a plurality of take-up parts 140, support parts 150 and fixing parts 151. The plurality of extension parts extend from the central part so as to respectively locate on the same plane, the plurality of connection parts respectively connect the adjacent extension parts to each other, the plurality of take-up parts are respectively disposed at tip portions of the extension parts, the support parts are disposed on surfaces of the connection parts such that longitudinal directions thereof become approximately parallel to the longitudinal directions of the connection parts, where a cross section of each support part on a surface orthogonally crossing the longitudinal direction of the support part has a U-shaped portion, and the fixing parts are disposed on the surfaces of the support parts.SELECTED DRAWING: Figure 1
