From warp preparation to loom tuning. Explains sheds, beat-up, take-up, and common faults. Includes reed and dent calculations, pick density planning, and productivity improvement with data. This section explains practical decision criteria, typical test methods, and failure modes that matter in real production. Readers get checklists, calculation steps, and case examples connecting specifications to cost, reliability, and compliance. Links map core concepts to upstream inputs and downstream processes so choices remain consistent across sourcing, manufacturing, and end-use performance. Each article includes definitions, diagrams where helpful, and plain-language notes to help newcomers ramp quickly while giving experienced professionals the depth needed to troubleshoot and optimize. Standards references are cited with context, and whenever trade-offs exist, we make them explicit so you can defend decisions.
Treats a braid as the mechanism it is: from a starting and finishing braid angle it returns the extension, the diameter it necks down to, the change in enclosed volume, the geometric limit of extension available, and how far the construction sits from the 54.74 degree angle at which a braided tube is neutral under internal pressure.
Calculator
Turns a published bobbin volume into the run a braider actually gets: yarn mass and length per bobbin, how fast each carrier draws it at the braid angle, the minutes and metres before the creel is empty, and the effective output once the change time is charged against every cycle.
Calculator
Derives repeat size, shafts for a straight draft, float lengths and intersections from a weave notation, then applies the Ashenhurst rule to give the yarn diameter, the maximum sett the structure supports and how much of it the actual sett uses.
Calculator
Works out warp throughput from count, ends and speed, derives the size box concentration that an add-on and wet pick-up together demand, and returns the cooked stock and dilution water the box consumes per hour along with its turnover time.
Calculator
Solves the areal weight mass balance for the warp and weft counts implied by a measured GSM, sett and crimp, then reports the weight each direction contributes, the tex equivalents and the resulting cover factors.
Calculator
Computes the extra path length a warp end travels when the shed opens, as strain at the top and bottom shed lines, checks it against the yarn’s breaking extension, and multiplies it by the shed cycles per metre to give the abrasion exposure a construction imposes.
Calculator
Prices the changeover as a fraction of the batch cycle, compares a random style order against one that groups similar warps into tie-ins, and converts the availability difference into metres and contribution across the shed.
Calculator
Converts measured bow depth and skew offset into the percentages the standards use, checks them against contract limits and the range a weft straightener can actually pull out, and prices the residue as panel twist and squaring trim down the roll.
Calculator
Turns a pair of abrasion cycle counts into the cycles gained per point of size add-on, checks the sized yarn against the abrasion the loom actually demands, and back-calculates the add-on that would just meet it – with the size paste and money that over-sizing costs.
Calculator
Converts warp, weft and mechanical stop rates per 100,000 picks into stops per hour, weights each by its own mean repair time to build the true downtime Pareto, and prices the result as lost metres and lost margin across the shed.
