Abstract

According to an embodiment, a winding apparatus includes a winding core and an air flow controller. The winding core winds a belt-shaped structure comprising a substrate and an edge-coating part that covers an edge of a substrate in a width direction, the edge-coating part being coated with a material liquid on a surface of the substrate. The air flow controller has a nozzle that performs at least either ejection or suction of a gas, and adjusts an air flow in the vicinity of the edge-coating part of the film of the belt-shaped structure, which is wound by a winding core.

First claim

What is claimed is:

1. A winding apparatus comprising:
a winding core configured to wind a band-shaped structure, the band-shaped structure comprising a substrate and an edge-coating part coated with a film on a surface of the substrate, the edge-coating part covering an edge in a width direction of the substrate; and
an air flow controller configured to adjust an air flow in the vicinity of the edge-coating part of the band-shaped structure wound around the winding core, the air flow controller comprising a nozzle configured to perform at least one of ejection or suction of a gas, the nozzle being configured to eject the gas against a carrying-in position of the band-shaped structure and a vicinity thereof and/or configured to suction the gas at the vicinity of the carrying-in position of the band-shaped structure, the band-shaped structure being introduced, at the carrying-in position, into an outer peripheral surface of a wound part of the band-shaped structure around the winding core.

2. The winding apparatus of claim 1 , wherein the air flow controller adjusts one or more of a direction, a flow amount, a speed, or a pressure of the air flow between the nozzle and the edge-coating part of the film.

3. The winding apparatus of claim 1 , wherein the air flow controller changes a position and a posture of the nozzle in accordance with a change in the carrying-in position at which the band-shaped structure is introduced into the outer peripheral surface of the wound part around the winding core.

4. The winding apparatus of claim 3 , wherein
the air flow controller comprises:
a touch roll that touches the outer peripheral surface of the wound part of the band-shaped structure around the winding core; and
a drive force transmitting unit configured to change the position and the posture of the nozzle in accordance with a diameter direction position of the touch roll with respect to the winding core.
