The fibers are delivered in the form of pressed bales. The clothings in the blow room machines first open the pressed fibers, which creates fiber tufts. This releases dirt particles (dust and seed-coat fragments) from the tufts which are then removed by blow room machines. The Graf card clothings are characterized by being particularly gentle to fibers and are both durable and resilient against damage.
Long-lasting Graf metallic card clothings for feed rollers provide cleaning that is gentle to fibers from the very beginning. The clothings are perfectly adapted to the customer's needs and machinery, and the fibers are processed efficiently. Whether it is interlinked clothings for an exemplary fit or clothings for grooved rollers, Graf’s comprehensive range of metallic card clothings offers a solution for every application.

Graf’s high performance metallic card clothings for opener rollers generate greater added value starting in the blow room. The durable clothings for opener rollers ensure a high degree of opening and cleaning of the fibers to be processed. The carding angle of the clothing is decisive for the cleaning efficiency. The greater the angle, the more effective is the opening of the fibers and ultimately the more in-depth the cleaning. For fine or clean fibers, it is recommended to use less aggressive clothings than for coarser fibers.

Precise stationary flat clothings favors the fine opening of the tufts and result in better removal of waste by way of gentle pre-carding. Graf offers different pre-opening segments depending on the customer requirements. The CUTTYSHARP alloy developed by Graf allows for an up to 30% longer lifetime in this process.
