A new technique for continuous measurement of the cloth fell movement and some of its applications

الملخص EN

A new technique for continuous measurement of the cloth fell movement is described.

The retention (retaining, R) and the expulsion (expelling, E) displacements of the cloth fell were precisely measured.

The technique is simple and straight forward.

It yields a continuous record of cloth fell movement for many machine cycles.

The technique was applied to picanol loom and could be applied to any loom.

The effect of loom speed and weft density on both forward (R) and backward (E) displacements of the cloth fell were determined.
