  • the generic devices are known from the prior art. With them food bars, such as cheese, sausage, or ham bars can be cut into food slices and portioned. When cutting, the food bar is transported in the direction of a cutting knife, which separates food slices from one end. At the other end of the food bar is held by a gripper, which transports the product continuously or discontinuously in the direction of the cutting blade. Many food bars have a contour that changes over the course of the product. Especially in the end area, where the products are held by the gripper, the contour of the food bar tapers very often. This is mainly related to the production process of food bars. For example, round caliber often have a tapered end at the end. Cheeses are also often round at the end.

In a further preferred embodiment, the surface is designed so that the gripper completely absorbs all forces occurring at the food bar towards the end of the cutting process, most preferably without loosening the connection between gripper and food bar and / or the food bar begins to oscillate.
  • the size and shape of the surface needed to cut the food bar as much as possible depends in particular on the consistency and the size of the cross section of the food bar. The larger the cross-section of the product, the larger must be the surface with which the end of the food bar rests against the gripper. In food bars with a particularly soft consistency, the contact surface is preferably comparatively large, while in comparatively hard products usually a comparatively small contact surface is sufficient.
