With a view to increasing the efficiency and the flexibility of the weaving machines, the manufacturers have made considerable efforts to find solutions capable of simplifying and speeding up the operations and the machine settings at style changing and to permit coping better with particular production requirements.
The Quick Style Change (QSC)
The weaving mills which produce small quantities per style (high-quality clothing) can increase the weaving efficiency by optimizing the style change. The Quick Style Change consists of a series of operations, which need to be carried out as quickly as possible.
By suitably designing the weaving machines, using new equipment and organizing systems, this
the operation is accomplished in about forty-five minutes by a single operator, thus saving a lot of
time.
The quick warp change (QWC)
The quick warp change (QWC) consists instead only of the replacement of an empty beam with a ready full beam, of knotting the new threads with those of the runout warp with an automatic tying-in machine, and of the forward movement of the warp beyond the
reed, to eliminate the knotted zone.
Reduction of the number of warp and style changes
In addition to QSC and to QWC, another possibility to reduce the incidence of the setting-up times is the reduction in the number of warp changes by using large diameter warp beams and take-up devices for large batch rolls, both installed outside the weaving machine, which besides for these aspects are also suited to particular weaving requirements. These machines are designed for a cost-effective production of standard fabrics or of particular fabric categories
Weaving machines of the new design
Another way to increase production is to design and manufacture particular weaving machines
which can offer very high weft insertion rates.
