16—The Position of the Cloth Fell in Power Looms

Abstract

A theoretical analysis of the factors governing pickspacing has been carried out as part of an investigation into the problem of setting-on places in woven fabrics. Mathematical expressions relating the rate of take-up to the position of the cloth fell and the latter to pickspacing are developed for both bumping and non-bumping conditions. Some features of the warp tension cycle are discussed and it is shown how the work done in beating up the new pick can be calculated.
