Technical Field

The invention relates to the technical field of spinning, in particular to a tool and a method for predicting the length of yarn on a loom beam.

Background

At present, most weaving equipment in textile factories comprises import equipment without a device for measuring the size of a warp beam on a weaving beam, and a lot of troubles are brought to production. Particularly, the existing looms have more looms, more weaving varieties and less order quantity, and the control of the loom time for accurately predicting the warp size of the loom beam is very important. The loom speed is high, need know in advance how much of the last beam of a loom book warp of car, just so can prepare next beam of a loom in advance, avoid too late to cause the loom production to break off knot, hinder production.
