Determination of the range for the spade size setting on the loom

Calculation method of the possible range for setting the spade size on the loom under certain shed sizes and the given parameters of shedding mechanisms is developed providing that within the limits of the given range the unhindered laying of the weft through the shed is kept and the technological process is set and followed. Range calculation of the spade size for certain conditions for the cotton plain fabric production having the article 484 is done using shuttleless STB looms in the production facilities of BPHO Company (Baranowichi). In the given case the spade may be set from the highest possible size (340) by the position of the loom’s main shaft to the minimum possible size (70) of the position. The optimal spade size must be set within the limits of this range.
