Provided are a transfer tape wheel device of an on-line tape pasting mechanism, a control method, an assembly, and a mechanism. The transfer tape wheel device of the on-line tape pasting mechanism includes a transfer tape wheel shaft and multiple transfer tape wheels. Multiple vacuum holes and multiple compressed air holes are opened on a transfer tape wheel of the multiple transfer tape wheels from an inner side to an outer side of the transfer tape wheel. A vacuum interface and a compressed air interface are separately mounted on openings at two ends of the transfer tape wheel shaft. An in-shaft vacuum main line and an in-shaft compressed air main line are disposed in a hollow channel of the transfer tape wheel shaft.

Provided is a device for correcting meandering of a strip material capable of correcting meandering caused in the strip material and conducting stable conveyance even when the meandering amount is small. The device for correcting meandering in a non-contact conveyance of a strip material that supports and conveys the continuously travelling strip material at a non-contact state by floating the strip material using a group of one or more floaters arranged in series, is characterized in that a gas nozzle for jetting a gas to a lower surface of the strip material is disposed in at least one section between the most upstream floater among the floater group and a conveyance roll located immediately upstream of the floater, between adjacent two floaters and between the most downstream floater among the floater group and a conveyance roll located immediately downstream of the floater as a mechanism for imparting tilting to the strip material to operate the tilting of the strip material in the widthwise direction above the floater.

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.

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.
