A method of aligning a flat or profiled metal sheet with preformed notches on the two sides of the metal sheet when the sheet enters into a bender or folding machine directly from a roll forming machine linked or joined to the folder. The metal sheet has to be effectively aligned on the folder before folding to avoid potential damages to the metal sheet of not being properly squared or angled on bending while reducing the times to produce the folded products. Moreover, this method according to the invention allows the metal sheet to feed directly into the folder from the rollformer without having to pass through an intermediary transfer table or aligning device/machine before entering the folder for folding or manual alignment in the folder.

Provided is a control device for a plate feeding device with which the amount of a plate transported to a processing device by the plate feeding device can be measured with high accuracy. This control device for a plate feeding device includes: a control unit that controls the rotation of a first roll and a second roll of the plate feeding device; a transmission unit that transmits an electromagnetic wave toward a plate; and a transmission unit that transmits the electromagnetic wave toward the plate, wherein the control unit measures the transport speed of the plate during a predetermined period on the basis of the frequency of the electromagnetic wave received by the reception unit, and measures the transport amount of the plate on the basis of the transport speed.

A press machine includes upper and lower crankshafts having the same amount of eccentricity and driven in opposite directions with a phase difference of 180 degrees, a slide and a bolster rotatably connected to eccentric parts of the upper and lower crankshafts, respectively, a parallel maintaining mechanism configured to maintain a parallelism between the slide and the bolster, and a clamp mechanism including an upper clamp attached to the slide and a lower clamp attached to the bolster. The slide and the bolster move toward/away from each other and advance/retreat together along a feed direction of a material in accordance with rotational driving of the upper and lower crankshafts. The clamp mechanism clamps the material when the slide and the bolster move toward each other and unclamps the material forwardly fed while being clamped when the slide and the bolster move away from each other.
