The present disclosure relates to a method and device for processing food. The device comprises at least two food slicing devices adapted to each produce partial portions, and a combination device disposed downstream of each food slicing device to combine the partial portions to a multi-type portion. A sensor assembly may be provided to determine at least one property of the partial portions, wherein a control device is provided to control the operation of the food slicing devices based on the properties of the respective partial portions to adjust the weight of the partial portions. A control device is alternatively provided to synchronize the timing of the slicing operation of the food slicing devices. A buffering device is alternatively provided between at least one food slicing device and the combination device to retain and release partial portions based on a control signal from a control device.

A sheet is cut between a first conveying unit and a second conveying unit in a state in which the first and second conveying units halt and in which an upstream conveying unit conveys the sheet at a first speed; after the sheet is cut, the first conveying unit conveys the sheet at a second speed higher than the first speed to reduce a slack formed during the halting; after the sheet is cut, the second conveying unit conveys the downstream-side sheet at a third speed higher than the first speed; if the third conveying unit is nipping the sheet during cutting, the third conveying unit conveys the sheet at the third speed; and if the third conveying unit is not nipping the sheet, the third conveying unit conveys the sheet at the third speed or a fourth speed after the detecting unit detects the sheet.
