1. A cutting device for cutting pre-fabricated transverse seams of a plastic-film sleeve that is filled with food, whereby each transverse seam of the film sleeve to be processed and continuously fed separates one portion of food from the next portion, wherein the device comprises:
(a) a rotatable knife holder having an axis of rotation and equipped with at least one cutting blade and one receiving part per cutting blade to receive the cutting blade, whereby the cutting blade has a cutting edge parallel to the axis of rotation and wherein the cutting blade extends from the axis of rotation, (b) the cutting blade is mounted on the receiving part such that the cutting edge extends beyond the receiving part and (c) a rotatable roller having a roller surface located proximate to, and having an axis of rotation parallel to the axis of rotation of, the rotatable knife holder,whereinthe receiving part comprises a heating element for heating the cutting blade andthe rotatable knife holder and the rotatable roller are configured to cause the cutting edge of the cutting blade of the rotatable knife holder to strike the surface of the rotatable roller when the rotatable knife holder is rotated, whereby the surface of the rotatable roller (4) engages with, and bears against, the cutting blade such that the cutting edge of the cutting blade and the rotatable roller roll off against each other during rotation of the rotatable knife holder. |
