Definitions

• This invention relates to plainwarp fabric having worked in rubber threads.
• Warp goods of this class with the rubber threads worked in by underlaying operations 5 under the ground thread are known, the underlaying of the rubber threads serving for rendering Vthe fabric elastic in both longitudinal and transverse directions. 'I'his eiect is brought about by tying up the rubber threads toward thev sides by the underlaying operations.
• warp goods of this type are, however, open to the objection that they tend to roll in from the longitudinal edges, whereby further working is seriously interfered with.
• the invention has for its object to overcome this drawback by continually working in the rubber threads in two or more underlayng operations toward one and the same side and then back again.
• Figure 1 shows a lapping diagram to give a clear view of the composition of the goods
• Figure 2 shows the meshes produced by the lapping shown in Figure 1.
• 'Ihe warp goods comprise a ground fabric 8, ller threads 9, and the rubber threads I0.
• the ground fabric 8 is lappedin the form of a simple half tricot lap.
• the rubber threads I0 are continually worked in under the threads of the ground 40 fabric 8 bytwo or more underlayingoperations toward one and the same side and then back again.
• the flller thread (Cl. ⁇ i6-192) arrangement 9 is inserted in the direction opposite to that of the ground fabric arrangement 8.
• the threads of the ground fabric are gathered in the lower lapping machine; the iller threads 9, in the machine above; 5 and the rubber threads I 0, in the uppermost machine.
• 'I'he threads 9 are immaterial to the invention, they merely ill the ground fabric and could be omitted, in which case the rubber threads I0 would be drawn into the machine disposed 1n above the machine for the threads of the ground fabric.
• ground fabric may of course be lapped differently than shown.
• rubber threads Ill can be lapped in some other way, for 16 instance by underlaying them each under 2.
• the numbers I to 6 indicate the courses in which the 20 racking of the rubber warp threads 9 is repeated.
• the upper lapping machine is the one which is directed toward the needles when the machines are situated upon that side of the needles from which the goods 25 are removed.
