An air-floating thin film bonding apparatus and its air-floating roller is provided. The apparatus is composed of an air-floating rollers, which can blow out airflow at a specific angle to be applied to the base film with three-dimensional obstacles. The positive pressure provided by the airflow can be utilized to fill the gap space caused by the three-dimensional obstacles. Therefore, the base film can bond to the bonding film tightly to overcome the wrinkles and defects caused by the three-dimensional obstacle and the problem of unflatness of the film-bonding can be solved.

A web forming device includes: a first material supply unit provided with a first release port that releases a first material containing a first defibrated substance and a first organic binder in a gas atmosphere; a second material supply unit provided with a second release port that releases a second material in the gas atmosphere, the second material containing a second defibrated substance and a second organic binder and being different from the first material; and a transporting unit that forms and transports an accumulated substance obtained by accumulating the first material and the second material. The second release port is positioned downstream of the first release port in a transporting direction of the transporting unit, and the accumulated substance is a laminate obtained by laminating a layer of the first material and a layer of the second material.

In a method and a device for correcting meandering of a strip material in an apparatus that performs conveyance of the strip material at a non-contact state by floating a continuously traveling strip material by a floater group, the strip material is tilted by forcibly changing a height position in the widthwise direction of the strip material in at least one of a zone between the most upstream floater in the floater group and a conveyance roll located immediately upstream of such a floater, a zone between two adjacent floaters, and a zone between the most downstream floater in the floater group and a conveyance roll located immediately downstream of such a floater, whereby the height position in the widthwise direction of the strip material above the floater is changed and a static pressure applied to the strip material above the floater is changed to correct meandering thereof.

A conveyance device includes a support having a support face configured to support a conveyed object and a fluid introduction device disposed outside the support. The fluid introduction device is configured to introduce a fluid between the support face of the support and the conveyed object, to form a fluid layer for floating the conveyed object. The conveyance device further includes a conveyor configured to convey the conveyed object being floating from the support via the fluid layer.

A device for the treatment of strand-shaped textiles includes a treatment container, a transport nozzle array, and a transport path by way of which a material strand can be moved through the transport nozzle array in a transport direction. The transport nozzle array includes a transport nozzle with nozzle inlet and outlet orifices for the material strand, between which are delimited at least two nozzle gaps for a transport medium. At least one of the nozzle gaps is adjustable regarding its gap width. At least one nozzle gap can convey the material strand in the transport direction, and at least one nozzle gap can convey the material strand in a direction counter to the transport direction. The device also includes a control unit that selectively drives the material strand in the transport direction or in the direction counter to the transport direction by appropriate actuation of the nozzle gaps.

A belt-shaped material conveying apparatus that supports a belt-shaped material conveyed in a conveying direction to a wind-up roll at a carrying-out side from a feed roll at a carrying-in side between these rolls in a noncontact state by air streams spouted to the belt-shaped material from support pads disposed to face a top surface side and an undersurface side of the belt-shaped material respectively, includes a pair of hydraulic cylinders as tilt means that tilts the support pad in the width direction of the belt-shaped material which crosses the conveying direction of the belt-shaped material.
