When the multiphase linear shed air jet loom M8300 goes on the market in late 1998, a large number of the 400,000 looms in world wide use will become obsolete. The M8300's ability to weave filling yarns at low tension and warps with a small shed and short beatup is ideal for many filament fabric constructions. Reversing the fabric weave layout reduces the maximum warp density restriction. Comparisons with conventional air jet looms show that the conventional loom had a weft insertion rate eqivalent to 33 percent of that of the M8300. The M8300 will require updated warp preparation machinery and improved yarn preparation, although increased yarn strength will not be necessary due to the lower tension and insertion velocities. The M8300 requires 50 percent of the floor space of conventional air jet looms and reduces electricity and air conditioning costs.
