New frontiers in preparation-to-weaving

By eliminating abnormalities, defects, and irregularities, and by monitoring every single thread during the preparation of the warps, one creates the conditions for optimal use, on the loom, of a wide range of yarns originating from any type of spinning machine. It must be recalled that, in order to keep costs down, and to keep up with the latest fashions, the modern weaving mill tries to be universal, and to use even delicate yarns with a high CV%, or fancy yarns that present a certain “defect rate”.
Setting up warps with these products thus becomes a delicate business and a good warper must be able to arrange them rationally, following the criteria of homogeneity and compactness demanded by the loom technology.
High quality of the warps prevents certain problems from arising not only during the weaving stage, but also later on during the downstream processing of the fabric (i.e., during dyeing, finishing and making up).
Over the years, warping technology has had to evolve considerably in order to adapt to the rapid technological evolution and growing production flexibility of weaving devices and weaving machines, as the latter strive to win over new markets and new consumers to more sophisticated, higher added value textiles.
Nearly all the manufacturers have developed (to varying degrees) their preparation machines, which can be regarded as the true partners of weaving machines, so as to make them able to meet the needs of the weaving mill and to help to bring down running costs.
There have emerged a number of technologically advanced machines that have solved the problems of the past and, at the same time, introduced certain innovations for specific processes.
If we take a look at this sector, in which last-generation machines are equipped with the most up-to-date warping process management systems, we find the new Versomat machine, by Benninger.
The Versomat has been present on the market for several months and sixteen of the machines have already been sold in Italy for applications in different market sectors, because the machine combines an entirely new process setting with newly developed technological principles.
