Abstract

A web transportation apparatus includes a mesh belt configured to be rotated to transport a web formed of a dry deposited material containing fibers and a striking member configured to strike a return section of the mesh belt to remove the material attached to the mesh belt. The striking member includes a striking bar and a striking lever. The striking bar is reciprocated to strike the mesh belt.

First claim

What is claimed is:

1. A web transportation apparatus comprising:
a mesh belt configured to be rotated to transport a web formed of a dry deposited material containing fibers; and
a striking member arranged adjacent to a return section of the mesh belt, the striking member including
a striking bar having an elongated shape extending substantially parallel to a surface of the mesh belt facing the striking bar and extending along a direction intersecting a transport direction of the mesh belt, and
a striking lever fixed to the striking bar to reciprocate the striking bar along a direction intersecting the surface of the mesh belt facing the striking bar to strike the mesh belt to remove the material attached to the mesh belt.

2. The web transportation apparatus according to claim 1 , wherein the striking bar is formed of a material identical to a material of the mesh belt.

3. The web transportation apparatus according to claim 1 , wherein the striking bar strikes the mesh belt by using an elastic force.

4. The web transportation apparatus according to claim 1 , further comprising a collection portion that collects the material detached from the mesh belt.

5. The web transportation apparatus according to claim 1 , wherein the striking bar is configured to perform a first striking action on the mesh belt and subsequently perform a second striking action on the mesh belt that was rotated, and
a distance between a position receiving the first striking action and a position receiving the second striking action in a lengthwise direction of the mesh belt is shorter than a distance between a starting point of the return section of the mesh belt and a striking position of the striking bar.

6. The web transportation apparatus according to claim 1 , wherein the striking bar is configured to strike a transportation surface of the mesh belt on which the material is disposed.

7. The web transportation apparatus according to claim 1 , wherein the striking bar is configured to strike a rear surface of the mesh belt opposite a transportation surface on which the material is disposed.

8. The web transportation apparatus according to claim 5 , wherein an entire length of the mesh belt is not equal to an integral multiple of an interval that is the distance between the positions of the mesh belt struck by the reciprocating striking bar.

9. A fiber article producing apparatus comprising:
a deposition unit including a drum configured to dry deposit a material containing fibers;
a web transportation unit including a mesh belt on which the material is deposited from the deposition unit and configured to transport a web formed of the deposited material on the mesh belt; and
a shaping unit including a pressing surface configured to press the web transferred from the mesh belt, wherein
the web transportation unit includes a striking member arranged adjacent to a return section of the mesh belt, the striking member including
a striking bar having an elongated shape extending substantially parallel to a surface of the mesh belt facing the striking bar and extending along a direction intersecting a transport direction of the mesh belt, and
a striking lever fixed to the striking bar to reciprocate the striking bar along a direction intersecting the surface of the mesh belt facing the striking bar to strike the mesh belt to remove the material attached to the mesh belt.
