Sorry, no etymologies found.
So my grandfather, who had his "pirn" contracts to be shipped for England on certain days, used to call his sons about him, and devote himself and all of them to the service of repairing.
In (hort, the fml is capable of two of which being very round and producliig all tlie commodities of the fteep, are called the pirn-heads of St. climate.
“The Keeper will rue this before year and day are out,” said a third; “the Master of Ravenswood is the lad to wind him a pirn.”
Modern pirn-winders are generally complex precision machines which are outside the manufacturing capabilities of local semi-skilled labour in developing countries.
On the basis of this information, it is possible to estimate the number of pirn-winding spindles required to meet a given weaving production target.
Given the spindle speed, and knowing the diameter of the empty pirn-tube and that of the wound pirn, the effective mean package diameter and the yarn speed in winding can be calculated.
When weft yarn is not on a package of suitable form to be placed directly onto the loom shuttle (i.e. when it is on ring rubes, cheeses, cones, or in hank form) it is necessary to rewind it on to pirn tubes of appropriate size.
- If the quality of the weft yarn is such that there is an appreciable variation in count from pirn to pirn, block barring will be noticed in the cloth.
On balance, one must conclude that, in most circumstances, the pirn-changer is to be preferred except where yarn suitable for the types of cloth covered by this memorandum is readily available only for use in plain (i.e. non-pirn changing) shuttles.
In the second method, which is currently by far the most common, the empty weft package (pirn) is ejected and immediately replaced with a new full pirn of weft.
