of an elastic yarn under any desired tension for
an inelastic yarn is a comparatively simple mat

However, where the yarn is supplied from
a beam and runs longitudinally of the direction
of the progress of the work through a machine,
the machine set-ups are comparatively complex
and it is highly desirable that the setting of the
machine be unaltered for long periods of opera
tion. Heretofore, in knitting fabrics having
elastic zones on what may be termed the beam
alternate and which are indicated by the refer
ence characters A and B. Intertwined with the
loops of the A type ribs are yarns b which are 10
confined to such ribs. These are elastic in the
elastic zone or zones and are inelastic in the in
elastic zone. In other words, it is the yams b

introducedor superadded to the regular thread
pattern in the elastic zone. While, this partially
solves the problem, it does not do so completely.
Also, it involves the use of the regular yarn in
addition to the elastic strands, which introduces
an item of expense beyond that prevailing where
a substitution is made. Indeed, the prevailing

In Fig. 6, I have shown one unit group of yarns
40 proceeding from the cones (not shown) to snub

elastic zone of the fabric, passing ?rst around
an additional snubbing rod ll, while the yarns

, From the snubbing rods l3, the yarns pass to a
yarn guide l5 where they are positioned in suit
able relation to each other and from which they
pass to a reel l6 upon which. they are wound. ' It
is to be understood that the unit group of yarns
50 shown in Fig. 6 is repeated a plurality of times
in ?lling a single beam for actual use. It is not
necessary to use the snubbing rod ll in the in
elastic zone since in that zone the elastic yarn
is not used for the yarn b and the extra snubbing
55 would be without utility and in the case of some
yarns even undesirable. From the reel l6 the
yarns are unwound upon a suitable beam, all
yarns being fed at the same rate from the reel

the knitting machine and the yarns knitted into

Having thus .described my invention, what I
claim is:
.
1. Process of making a knitted fabric com
prising beaming a warp composed of unit groups
of yarns, corresponding yarns of each unit being
in one group of units elastic and in another
group inelastic, said elastic yarns being under
higher linear strain than the others on the beam,
fabricating the‘yams making up both said groups
45
of units in a uniform thread pattern, the corre
sponding yarns of each unit being fed from ‘the
beam at the same rate- whereby a fabric is pro 50
duced having a compact highly elastic zone and
'a less compact inelastic zone.
2. Process of making a knitted fabric compris
ing beaming a warp composed of groups of yarns,
one or more yarns of each group being, in one 55
zone of the warp -elastic and in another~ zone '
thereof inelastic, said elastic yarns being Put
under higher linear strain than the others 'on the
beam, knitting'the yarns of bothezones into an
essentially uniform thread pattern, the corre 60
sponding yarns of each unit being fed from the
beam at the same rate whereby a fabric is pro
duced having a compact, higl1__ly_elastic zone and
a less compact and relatively inelastic zone.
