were feed from eight packages 2 only four of the eight packages are shown in fig3 four of the eight yarns were brown two yarns were beige one yarn was orange and one yarn was white each of the yarns 1 was first threaded through an individual guide 3 following which all eight yarns 1 were together threaded through a group guide 19 the feed yarns 1 were then directed through a preinterlacer 20 the preinterlacer 20 was supplied with compressed air at approximately room temperature and at a pressure of 150 psig the preinterlacer 20 had a circular yarn throughout passageway 0 1875 inch in diameter and 0 30 inch long the preinterlacer had three jet orifices each of which intersected the axis of the yarn throughput orifice at an angle of 90 degrees the axes of the three jet orifices were in a single plane and were positioned equidistantly from one another so that there was no net directional effect on the yarns being preinterlaced each jet orifice had a diameter of 0 0625 inch after passing through the preinterlacer 20 the feed yarns 1 came into contact with a first pretensioning godet 4 after making three wraps around the first godet 4 the combined feed yarns 1 made seven wraps around a second godet 5 the second godet had a surface speed of 372 meters per minute and was heated to a temperature of 50 u00b0 c from here the yarns 1 made ten wraps around a third godet 6 the third godet 6 having a surface speed of 1200 meters per minute and a temperature of.
