- Abstract (EN)
- Content: This article wants to combine two perspectives: First, Leather production, focused on the splitting process, with its diverse quality requirements and second, the new evolutions in the field of bandknife properties. In a short introduction the splitting process as such will be described, its different use in several stages and leather types, also in the field of leather conversion (in shoe, leathergoods and automotive parts production). Influencing factors of the possible goals like quality and cost efficiency will be discussed. In the second part some main requirements and problem fields of leather splitting are analyzed in more detail. Requirements such as thickness tolerance, tensile strength, flexibility, fibre-free smooth cutting surface. Difficulties in practice like chrome nests, hard water, poor raw material, feeding speed, influence of abrasivity of leather. In a third part the physics of the cutting process as such will be described. Explanation of basic terms as “cutting ability”, “edge retention”, “pull vs. press cut”. Resulting from this we get important parameters that refer to the bandknife blade: e.g. steel characteristics (hardness, flexibility, grindeability, microstructure at cutting point, geometry of knife bevels, weldability etc.). The possibilities in modern bandknife production will be shown as for example: CNC-sensor-based tolerance measurements, presharpening, surface roughness variations. This is completed with a short view on the other components of the process like splitting machine (points like sharpness measuring), grinding stones (roughness-exactness controversy diagram). The fourth and last part puts the two perspectives together: Optimized bandknife characteristics for specific leather material. Alternative steel types that due to new properties allow to meet also new requirements. Take-Away: Optimization of the splitting process Better understanding of the bandknife properties
