The improvement of roving compactor construction in spinning machines

Аннотация

The article provides an analysis of the process and elements of the roving in the drafting devices of spinning machines. An effective scheme for roving compactor is proposed. The results of theoretical studies of the process of roving according to the existing and proposed scheme are presented. The parameters of the seal are justified. The results of the experiments determined the comparative indicators of roving using the recommended roving compaction technology. In the process of compaction of roving fibers, the main parameter is the friction force between the fibers and the influence of the geometric parameters of the compactor on it. To study the effectiveness of the recommended roving compactor with grooves of drafting devices on roving frames, spinning machines, several variants of the developed compactor were made. Comparative experiments were presented on Zinser 350 machines under production conditions. The parameters were measured in a spinning mill, and the results were processed in a special laboratory.
