Abstract

The subject of research is the process of shedding on narrow looms. The article analyses parameters of shedding under a sinusoidal law of motion of the heddles frame and studies motion parameters rapier for weft insertion in the shed. It shows the possibility of reducing the height of the shed depending on the width of the produced ribbons, spade value of narrow looms and other factors. The results of calculations of the motion of the heddles frame for the conditions of the production of narrows of different width are presented.

The proposed method allows determining the optimal adjustment parameters of shedding for each specific refueling of narrow looms to reduce the height of the throat, reducing deformation of the warp threads in shedding, reducing breakage, improving the quality of narrow fabrics and reduce dynamic loads.
