Abstract
The following paper presents the solution to the problem of searching the best shape – structural form of the bottoms and optimal dimensions of the main cylinder of the carding machine with consideration to the criterion of minimal deflection amplitude of its shell. The Finite Element Method has been applied for searching the optimal solution. As a result of the performed analyses, reduction of deflection amplitude at approximately 77% has been obtained. The determined optimal structural form and dimensions of the cylinder enable application of a new textile technology – microfibre carding as well as improvement in the quality of traditional carding technology of woolen and wool-like fibres performed on roller carding machine. The final stage of the work has been to determine the influence of manufacturing tolerances of the cylinder and metallic card wire on the amplitude of the main cylinder deflection.
