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.

The problem of providing an apparatus for conveying a molded body for heat exchanger fins that is capable of realizing high speed conveying of the molded body for heat exchanger fins, preventing the generation of noise during conveying, and miniaturization is provided. An apparatus conveys a metal strip in a predetermined direction after tube insertion portions are formed in a thin metal plate, and has a plurality of conveying units disposed along a conveying direction of the molded body for heat exchanger fins, each conveying unit including: a rotating conveyor that has a plurality of tapered protrusions that are capable of advancing into the tube insertion portions and a rotating shaft in a direction that is perpendicular to a conveying direction of the metal strip on a horizontal plane; and a rotating conveyor driving unit that rotationally drives the rotating conveyor. An operation control unit that controls the plurality of rotating conveyor driving units so as to synchronize respective rotational speeds of the plurality of conveying units is also provided.

A detaching method of sheets from a stack of sheets from a stack of sheets and a relative detaching apparatus is disclosed, including at least a gripping head of a handling device of sheets and a nozzle assembly apt to eject an air flow to a lateral edge of a stack of sheets, furthermore including: a storage assembly of pressurised air provided at least with a compressed-air tank equipped with a pressure multiplier and a relative first pressure adjuster; and a high-pressure pipe between the nozzle assembly and the storage assembly intercepted by a fast-opening electrovalve.

Two-dimensional material sheets are stacked in a stacking device. One of a printing machine and a coating machine has at least one stacking unit having a stacking space. Material sheets are conveyed, via the stacking space of the stacking unit, comprised by the stacking device, and are deposited into a stack on top of one another on a loading aid. For two different production runs, the stacks are formed on the loading aid with the four corners of their areas in mutually different relative orientations with respect to the loading aid, which is arranged, in each case, in the stacking space of the stacking unit and is larger-format compared with the material sheets to be deposited in each case. For the two production runs, in each case, one loading aid of the same format is positioned on different positions, as seen in projection in the horizontal, in the stacking space of the stacking unit.
