Abstract

An object of the present invention is to develop: a method of efficiently producing a long bagworm silk thread containing no contaminant while preventing a change in the spinning direction and the runaway of the bagworm from a rail, and alleviating a burden on the bagworm; and an apparatus for implementing the thread-producing method. Provided is an apparatus for producing a bagworm silk thread, having a movable rail having a width smaller than the maximum width between the right and left legs of a bagworm and configured to move in the longitudinal direction and to be able to hold with the legs of the bagworm; and a fixator configured to fix a bagworm, wherein the fixator is placed at a position such that the fixed bagworm can hold the movable rail.

First claim

The invention claimed is:

1. An apparatus for producing a bagworm silk thread, comprising:
a movable rail configured to move in a longitudinal direction of the movable rail; and
a fixator configured to fix a bagworm, wherein
the movable rail has a width smaller than a maximum width between right and left legs of the bagworm fixed to the fixator, and is configured to be able to hold with the right and left legs of the bagworm,
the fixator is placed at a position such that a fixed bagworm by the fixator can hold the movable rail,
the apparatus further comprising one or more peeling containers,
the one or more peeling containers being configured to store a peeling solution or a peeling vapor for peeling a spun bagworm silk thread from the movable rail, and
a part of the movable rail being placed at a position such that the part of the movable rail can come in contact with the peeling solution or the peeling vapor in the one or more peeling containers.

2. The apparatus for producing a bagworm silk thread according to claim 1 , further comprising a collection device,
wherein the collection device is configured to collect a bagworm silk thread peeled from the movable rail.

3. The apparatus for producing a bagworm silk thread according to claim 1 , further comprising one or more thread hooks,
wherein the one or more thread hooks is configured to change a thread reeling direction of a bagworm silk thread peeled from the movable rail.

4. The apparatus for producing a bagworm silk thread according to claim 1 , wherein the movable rail is a loop-shaped rail.

5. The apparatus for producing a bagworm silk thread according to claim 4 , wherein the movable rail is circular.

6. The apparatus for producing a bagworm silk thread according to claim 1 , wherein the movable rail is a rail configured to automatically move.

7. The apparatus for producing a bagworm silk thread according to claim 2 , wherein
the collection device comprises a bobbin on a periphery of the collection device, and
the bobbin is configured to reel a collected bagworm silk thread.

8. The apparatus for producing a bagworm silk thread according to claim 7 , wherein
the bobbin comprises one or more concavities and one or more convexities along a wind-up direction, and
the one or more concavities and the one or more convexities are configured to receive the collected bagworm silk thread.

9. The apparatus for producing a bagworm silk thread according to claim 7 ,
wherein the apparatus is configured such that the movable rail and the collection device synchronously rotate with each other.
