An in-line dumpling molding system is disclosed. The in-line dumpling molding system according to the present invention comprises: a dumpling wrapper cutting device, which cuts a supplied dough sheet to form dumpling wrappers; a dumpling-molding lower folding device, which is disposed below the dumpling wrapper cutting device, on which the cut dumpling wrappers are loaded, and which presses and folds the dumpling wrappers onto which dumpling fillings have been supplied; and a sealing device, which is disposed above the dumpling-molding lower folding device, and presses and seals the folded dumpling wrappers.

To provide a food dough spreading method for gradually spreading food dough to make it thinner by supplying the food dough between a plurality of spreading rollers in a spreading unit in which the spreading rollers are arranged in a V-shape. By adjusting a distance between a pair of vibration applying members provided between the spreading rollers arranged in a V-shape, a width dimension of the food dough flowing out from the spreading unit (25) is adjusted, and the vibration applying members are reciprocatively vibrated in a longitudinal direction of the spreading rollers at a position where the width dimension is adjusted. The reciprocative vibration of the pair of vibration applying members is vibration in a direction of approaching and separating from each other.

This pinching-shaping device includes cylindrical tools, each having a central axis of tool rotation, the central axes being parallel and the outer peripheries of the tools applied tangentially against one another to pinch-shape a strand tangentially introduced between the tools during rotation. The outer periphery of each tool has radially projecting blades distributed around the central axis, each providing a pinching surface. The pinching surface extends between first and second ends inclined to the central axis. The blades of each tool are distributed following the outer periphery, alternating inclination. When a blade of the first tool is radially interposed between the two tools during the rotation, it is radially aligned with one of the blades of the second tool, the pinching surface inclined in a complementary manner to the pinching surface of first tool's blade, pinching the strand between pinching surfaces of these two aligned blades.

Rolled food products are produced by cutting a dough sheet to form a roll sheet having a continuous pattern. The pattern is comprised of an asymmetrical repeat unit. The roll sheet is transported in a first direction with a conveyor system, and the roll sheet is rolled in a second direction to form a continuous roll. The second direction is not parallel to the first direction. The continuous roll is cut to form a plurality of rolls. Each of the plurality of rolls is asymmetrical.
