Registration inspection of composite products during the fabrication of a series of such products is accomplished by making a two-dimensional image of a product and analyzing the image to determine the location of at least one component in the machine direction and the location of at least one component in the transverse direction. The thus determined locations are compared to the desired locations for the respective components in the composite article, and feedback control signals are utilized to adjust the fabrication process so that the components will be at the desired locations in subsequent products. When a component is outside of its acceptable position, the article can be removed from the fabrication line without further processing. The invention is particularly useful with fabrication lines for the production of absorbent articles, such as disposable diapers, incontinence devices, sanitary napkins, and the like.

The invention concerns a method of regulation in winding, wherein a number of separate rolls (13a, 13b) are formed around separate roll cores placed one after the other side by side while supported by support members (11, 12) and while loaded by linear loads produced by the truncated rolls (14a, 14b) in a set of truncated press rolls (14). In the method of regulation, the distance at each particular time between at least one truncated roll (14a, 14b) in the set of truncated press rolls (14) and the beam (16) that loads the set of truncated press rolls (14) is measured. The measurement signal (S) is passed to a regulator (23), which gives a regulation signal (d) to the valves that control the actuators (17) of the beam (16) so as to adjust the distance between the beam (16) and the set of truncated press rolls (14) to the desired measure.

A sheet transport device includes a sheet load tray on which a sheet is loaded, a side-edge positioning unit, and a regulating unit. The side-edge positioning unit comes into contact with a side edge of the sheet in a direction intersecting a sheet transport direction at an upper surface of the sheet load tray and positions the side edge of the sheet to a normal position. The regulating unit is provided in a rotatable manner about a rotation shaft at a lower surface of the sheet load tray and regulates an output position of the sheet by rotating a stopper of the regulating unit to a position where the stopper is capable of colliding with a downstream edge of the sheet to be output in an output direction when the side-edge positioning unit moves to a position corresponding to a minimum width of the sheet.
