A method for correcting an alignment of a cutting layer made up of stacked, sheet-format product in the form of sheets in relation to a cutting plane of a cutting blade of a cutting machine, and a cutting machine. The cutting machine has a feed saddle for displacing the cutting layer in the direction of the cutting plane of the cutting blade, wherein the feed saddle is adjustable in its alignment in relation to the cutting plane to change the alignment of the cutting layer pressing against the feed saddle in relation to the cutting plane. The respective sheet is provided with at least one cutting test mark, wherein the respective cutting test mark has a coloration changing in the feed direction of the feed saddle.

Provided is a method for bucking a stem that utilizes the combination of moving sensor and a fixed sensor. The fixed sensor measures a location of a first end of the stem travelling on a conveyor to determine a travel distance the first end has moved past the fixed sensor. The movable sensor measures a location of a second end of the stem to determine a sensor distance between the fixed sensor and the movable sensor. The length of the stem is determined by adding the travel distance to the sensor distance.

A paper cutting apparatus comprises a cutting unit to cut paper, a moving unit to move the cutting unit in a direction intersecting the conveyance direction of the paper, and a motor to drive the moving unit. The paper cutting apparatus also includes a detection unit to detect the current value of the motor and a determination unit to determine the state of the current value while the cutting unit that has begun moving from a specific position toward a target stop position is moving from a downstream end of the paper to a predetermined target stop position in the movement direction of the cutting unit. A control unit is configured to stop the drive of the motor on the basis of the determination result of the determination unit.
