FeatureRachel warp knitting m/c:
1. Rachel m/cs used latch needles together with a wire or blade
2. It has a gauge expressed in needles per 2inches
(5cm) so that for example a 36 gauge Rachel m/c will
have18npi
3. Their chain links are usually numbered in even
numbers 0, 2, 4, ….etc generally with 2 links/course
4. Rachel sinkers only performs the function of holding
down the loops whilst the needles rise
5. Rachel sinkers are not joined together by a lead across
their ends nearest to the needle bars so they can move away
clear of the needles towards the back of the m/c for the rest
of the knitting cycle
6. The fabric is drawn downwards from the needles,
almost parallel to the needle bar at an angle of 120°-160° by
a series of take-down rollers.
7. The warp beams are arranged above the needle bar,
centered over the rocker shaft, so that the warp sheets pass
down to the guide bars on either side of it
8. The beams are placed above the m/cs so that it is
accessible at the front for the fabric inspection
9. At least four 32″ diameter beams or large numbers of
small diameter pattern bars
10. The guide bars are threaded, connecting with the
middle bars and working outwards from the eitherside of the
rockershaft
11. The guide bars are numbered from the front of the m/c
12. The needle trick plate acts as a fabric support ledge
and knockover surface.
