In the first step, the cattle hides are freed from fat, soluble protein components and the subcutaneous connective tissue in the so-called water workshop. In addition, foreign components such as dirt and preservatives are removed. The hides and skins are then fleshed with the help of the tanning tree and a shearing knife. Ideally, the tanning tree has a curvature so that each area of the skin can be treated individually. Finally, the fleshed skin is swollen to ensure optimal absorption of tannins.

The perishable protein fibers of the hides prepared in the water workshop are then transformed into leather fibers by the accumulation of tanning agents and are protected against decomposition by microorganisms. Various forms of tanning have been developed over the centuries - from environmentally friendly forms that do without chemical additives to industrial processing. Based on tried and tested recipes, the skins and that we use for our patchwork carpets, for example, are characterized by their resistance to aging and high humidity. Our partner companies also tan in permanently rotating barrels and thus achieve complete and even tanning. The result: hides with a high level of elasticity and suppleness.
In the last step, the so-called dressing, the hides and skins are washed, spun and greased. The greasing process has the task of making the skin fibers soft, supple and water-repellent. Here, fat is only stored in the interstices of the three-dimensional fiber network. The fiber itself does not absorb fat, so it remains flexible and does not stick together. The greased hides are then spun again and nailed onto a wooden frame, stretched smooth and dried. Following this, the hides and skins are gently drummed by hand (also known as "stollen") and the last remnants of the subcutaneous connective tissue are removed.
