As a result of the analysis of technological processes of textile production, it was found that control methods at each technological transition are essential to ensure high product quality and labor productivity. In the spinning and rewinding phase of the formation of textile packages, their shape is an important parameter. The shape of the package and its deviations from the given one can be used as a complex indicator that characterizes the quality of the product of the corresponding technological transition, but also as a characteristic of the technical level and condition of the equipment used and the optimality of technological production modes. To obtain complete information about the shape of the package, it is necessary to have cross-sectional profile images at the ends and generatrix. An analysis of the methods for controlling the shape of technical objects showed that a promising direction for controlling the shape of cross-wound packages in the textile industry is the shadow projection method in combination with automated pattern recognition tools. For the successful implementation of the method, a theoretical analysis of the influence of the design parameters of the transducer on measurement errors was carried out. Reasonable requirements for the mutual arrangement of the elements of the transducer relative to the controlled object are established. Relationships are obtained that allow predicting the parameters of the device, in particular, the scale of the transformation. The substantiation of the choice of means for digitizing the resulting images for subsequent automated pattern recognition has been carried out.
