Based on the shadow projection method, we obtain an initial image of the surface of a textile packing with the purpose to digitize and subsequently analyze it by the methods of technical vision. We received dependences of the scale of conversion of the shadow size at the surface of a packing, caused by the deviation of its shape from the specified one, into a digitized image. The assigned packing shape is determined by the conditions for its processing during subsequent transitions in textile production. The images received with a sufficiently high frequency of observation are the data for consequent construction of a volumetric model of the packing. Using this model, it is possible to establish deviations in the packing shape form the required one, caused by a violation of conditions in the formation of packing. The impact of design elements in a device for the registration of initial data on the magnitude of conversion scale is established. As a result of research, we received dependences that allow us to reasonably approach the selection of design parameters of a device. The device to control the shape of packing in the process of its unwinding makes it possible to eliminate design defects at the stage of adjusting the mechanism of a bobbin winder and to formulate requirements for its operation.
