The technique of reconfiguration the patterns of ribbed construction for the manufacturing of fabrics on weaving looms with a mixed harness ties of neck-cords into a comber board

Abstract

Weaving machines with various options of mixed harness ties of neck-cords into a comber board are installed at the Orsha Linen Industrial Complex. These harnesses are designed to produce tablecloth fabrics, the demand for which has significantly decreased in recent years. Consequently, this production equipment is forced to stand idle, leading to a decrease in economic performance and competitiveness of the enterprise. Tablecloth fabrics and single product tablecloths feature a central part (center weave or plain weave ground) and a symmetrical border pattern at the selvedge ("drop" or border of the tablecloth). For the manufacturing of this product range, the Orsha Linen Industrial Complex uses weaving machines with various variants of mixed harness ties of neck-cords into a comber board. Mixed harness ties consists of a straight harness tie (one-, four- or five-part) in the plain weave ground and center one-part harness ties in the border of the tablecloth. However, due to the complexity of the mixed harness ties, this equipment is not designed to produce the repeat of construction patterns used in the suiting cloth, as it leads to a failure of the interlacing pattern at the junction of the straight and center harness ties. The aim of the study is to develop a methodology for designing and rebuilding ribbed weaves for the manufacturing of fabrics on weaving machines that have mixed harness ties of neck-cords into a comber board. The article is devoted to the development of a technique for designing suiting cloths made with ribbed construction on jacquard weaving looms, the refueling scheme of which is used for the manufacture of products tablecloths with a border pattern. The essence of the technique is to reconfiguration the basic construction in order to obtain vertical symmetry. This makes it possible to eliminate the failure of the pattern’s construction at the junction of two harness ties and create a greater variety of suiting cloth produced at the Orsha Linen Industrial Complex. The technique telescope into the forced inactivity of equipment and does not require additional costs for reprogramming jacquard machines when changing the product range.
