Calender, Mixing and Smoothening Rolls

Calendering, pressing, mixing and smoothening for these manufacturing processes, precision rolls are used in order to guarantee that the final products have the optimum properties. It is obvious that rolls used for these purposes must meet extremely high standards, since the quality demands for production, converting and treatment of materials in continuous runs can only be achieved using rolls of maximum precision with respect to geometry, runout and surface finish. Throughout the world, machine and equipment manufacturers as well as end-users involved in the processing of paper, foils, plastics, rubber etc. are our customers. All sizes of rolls are supplied in any design which may be required. Through close co-operation with our customers we are fully familiar with their requirements. By purposefully gearing our production range and services to suit our customers' needs, we are able to develop and provide products now, which will meet future demands. Rolls produced by Breitenbach are manufactured to comply exactly with customers' specifications or they are designed and produced in close co-operation with the end-user. Mechanical and thermodynamic strains are taken into account. One-hundred-percent inspection is of great importance to us. Each manufacturing step is fully documented, because complete quality assurance is a matter of course for us. Research and development are considered as means of constant improvement of materials, processes and service, and these processes are continuous.

Coating and Doctor Rolls

Coating, painting, impregnating of materials in continuous runs such as paper, cardboard, plastics and metal foils, textile fabrics and non-wovens, this is the range of application for our rolls. Whenever materials in continuous runs are processed, high-precision coating rolls are needed, in order to meet the high quality standards which are specified for all final products. The slightest deviation in cylindricity and runout may lead to significant differences in the coating quality and thickness. The more precise the roll, the better coating quantity and uniformity specifications can be met. When calculating the savings for one production year or even for the service life of the rolls, the investment in roll precision will pay off. At Leonhard Breitenbach GmbH, the standards for quality and precision are extremely high. This has made us the market leader for this product range on a worldwide basis.

Crushing Rolls

Grinding, refining, squeezing, crushing, flaking these are tasks putting rolls into focus as the most important tool. Highly precise crushing rolls made by Leonhard BREITENBACH GmbH are, amongst other applications, used for preparing the following products: foodstuff including luxury foods animal feed pharmaceutical products colours fertilizers ceramics and stoneware BREITENBACH crushing rolls enhance the efficiency and profitability of various production processes in several respects. On the one hand, maintenance intervals are significantly extended without affecting reliability. This means longer machine cycles without interruption, and the repair costs are cut down to the required minimum. Reduction in energy consumption during grinding is another important benefit offered by our rolls. Furthermore, we have continuously developed our products and adapted them to actual market requirements, in close cooperation with renowned mill and plant manufacturers. This dialogue in partnership along with our experience over many years makes BREITENBACH a reliable partner specialising in the field of roll manufacture for all crushing applications.

Heat Transfer and Chill Rolls

Heating and cooling. The production of paper, foils, plastics, rubber etc. in continuous runs usually requires thermal treatment of the material during the production process. Whether during manufacture, converting or processing, a correct roll temperature with least tolerance is vital. In order to guarantee constant product quality and properties, the standards set for both heat transfer and chill rolls are extremely high. With regard to planning and design, we place our trust in our in-house research department. Thermodynamic simulation and calculation is made, on the basis of which design engineers develop individual solutions. This enables us to design and to manufacture heat transfer and chill rolls which are characterised by an extremely uniform distribution of temperature on their surface. Controls and checks accompany the complete production process and guarantee a consistently high quality level.
