Title:
NON-CONTACT TRANSPORT DEVICE AND MANUFACTURING METHOD OF FILM
Document Type and Number:
Japanese Patent JP2023047904
Kind Code:
A
Abstract:
To provide an inexpensive non-contact transport device which enables reduction of a possibility that a transported object contacts with the non-contact transport device with a simple structure and to provide a manufacturing method of a film which uses the non-contact transport device.SOLUTION: A non-contact transport device (1) includes a columnar roll (11) having a transport surface (13) which guides an elongated transported object (K) transported from the upstream side of a transport path to the downstream side of the transport path. The transport surface (13) is formed with jet holes (13a) which jet a gas for lifting the transported object (K). At positions which are located at areas on the upstream side and the downstream side on the transport surface (K) and different from positions of the jet holes, protruding parts (13b) or recessed parts extend along a width direction of the transport path or multiple protruding parts or recessed parts are provided along the width direction of the transport path.SELECTED DRAWING: Figure 2
