Abstract

According to one embodiment, a spinning apparatus includes a spinning head and a rotational brush. An organic material is filled up inside the spinning head, and the spinning head ejects the organic material on a surface of a base to form a sheet of the organic fiber on the surface of the base. The rotational brush includes a plurality of brush bristles and is rotated while the brush bristles are in contact with the sheet in the surface of the base. The rotational brush strips the organic fiber from a part of the sheet by the rotation.

First claim

What is claimed is:

1. A spinning apparatus comprising:
a sheet forming machine comprising:
a spinning head inside of which an organic material can be filled up;
a rotational brush which includes a plurality of brush bristles and configured to be rotationally driven; and

wherein the sheet forming machine is configured to control the spinning head and the rotational brush to:
make the spinning head eject the organic material filled up on a surface of a base to form a sheet of an organic fiber on the surface of the base in a state that both side edges of the base are covered by the sheet of the organic fiber;
rotate the rotational brush while the brush bristles are in contact with the sheet in the surface of the base;
make the rotational brush strip the organic fiber from a part of the sheet by the rotation so that the part of the sheet, in which the organic fiber is stripped, is formed for only a predetermined dimension from one of the both side edges, one of the both side edges being not covered by the sheet of the organic fiber and the other of the both side edges being covered by the sheet of the organic fiber after stripping by the rotational brush; and
make the rotational brush strip the organic fiber from the part of the sheet by the rotation so that a part of an outer surface of the base, in which the organic fiber is stripped, is exposed to an outside.

2. The spinning apparatus according to claim 1 , wherein
each of the brush bristles of the rotational brush has a wire diameter in the range of 0.1 mm and 0.5 mm, and a brush length is 30 mm or shorter.

3. The spinning apparatus according to claim 2 , wherein
each of the brush bristles of the rotational brush has the wire diameter of 0.2 mm or greater, or a ratio of the brush length to the wire diameter is smaller than 50.

4. The spinning apparatus according to claim 1 , further comprising:
a suction head on which the rotational brush is mounted and which has a suction opening, wherein
the sheet forming machine is further configured to control the suction head to suction the organic fiber removed by the rotational brush from the suction opening.

5. The spinning apparatus according to claim 1 , further comprising:
a voltage generator which is configured to apply a voltage between the spinning head and the base, wherein
the sheet forming machine is configured to control the voltage generator to apply the voltage between the spinning head and the base so that the organic material is ejected onto the surface of the base from the spinning head.

6. A manufacturing method of a sheet of an organic fiber, comprising:
ejecting an organic material filled up inside of a spinning head onto a surface of a base to form a sheet of an organic fiber on the surface of the base in a state that both side edges of the base are covered by the sheet of the organic fiber;
rotating a rotational brush, which includes a plurality of brush bristles, while the brush bristles are in contact with the sheet in the surface of the base;
stripping the organic fiber from a part of the sheet by the rotation of the rotational brush so that the part of the sheet, in which the organic fiber is stripped, is formed for only a predetermined dimension from one of the bath side edges, one of the both side edges being not covered by the sheet of the organic fiber and the other of the both side edges being covered by the sheet of the organic fiber after stripping by the rotational brush; and
stripping the organic fiber from the part of the sheet by the rotation so that apart of an outer surface of the base, in which the organic fiber is stripped, is exposed to an outside.
