Improvements in or relating to the Manufacture of Knitted Lining
Fabrics.
JACQUES SCHIESSER, of Radolfzell, on the Lake of Constance, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
"
The manufacture of lining fabrics with binding thread on a French circular frame
is effected, as is well known in such manner that the lining thread supplied to the
needles is at first knocked off alone over the sunk thread of the next loop-wheel, and
only knitted to the fabrics suspended on the needles after a second thread has been
introduced by a second loop-wheel. The loops of the finished fabric thus consist of
at least two threads of which the one sunk first forms the so-called "binding
thread and the one sunk second forms the covering thread. The loops of the lining
thread are held together only by the binding thread which also forms the left hand
side of the loops the covering thread serving solely to form the right hand side of
the loops. When it is desired to produce patterns in such a fabric the lining thread
must be knitted into loops in places where pattern loops are to be produced, while
the binding and the covering threads on the contrary are guided on the back of the
fabric as loose meshes.
To effect this, needles are used having unequally long points, which needles
according to the length of said points enable the threads sunk to come either over
or under their hooks. At the same time presser wheels corresponding to the
pattern are used for knocking over the loops of the lining thread said presser
wheels not pressing the needles over the points of which the sunk thread is going,
and leaving the lining thread loops in question under the needle-point.
The accompanying drawing illustrates the process according to this invention in
different stages of working of the frame. The lining thread f is in this construction
fed to the needles and n¹ by means of a lining apparatus 1 : 1. In Fig. 1 the
binding thread bis sunk and, as the central needle n³ has a little longer point than
the others the thread does not come under, but over its point. When the binding
thread 6 (Fig. 2) is pushed out by the sinkers of the loop-wheel, the loop correspond-
ing to the needle n falls down as it is not held by the needle-point, and does not
form a loop. Accordingly as shown in Fig. 3 only the points of the needles n are
pressed down by means of a suitably recessed presser-wheel, the point of the
needle n¹ remaining open. Then the lining thread f which in Fig. 2 is still behind
the needle-points is advanced and comes over the depressed points of the needles n
on to the binding thread b and becomes looped with the latter as shown.
Simultaneously with this action, the lining thread loop of the needle n¹ is caught
by the open needle-hook and not knocked over, for the purpose of forming a
pattern loop.
Figs. 4 and 5 show the introduction and pushing out of the so-called covering
thread o by the second loop-wheel. The same action takes place as in Figs. 1
and 2

page_text: Finally the fabric suspended on the needles and consisting of loops e e¹ is
knocked off, by means of a smooth presser wheel, over all the needles (Fig. 6)
and thus a pattern is formed on the needle n' by the lining thread f.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that
what I claim is :-
1. A process for producing coloured patterns in a lining fabric made with a
binding thread, the lining thread laid on the needles n and m in the well known
manner, being guided at the places where pattern loops are to be produced under
the needle-points n¹ during its knocking over the binding thread b effected by
the first loop-wheel while on the other hand both the binding thread b as well
as the covering thread o to be treated by the second loop-wheel, are guided at the
same places over the needle-points and whereby the lining thread portions which
have not been knocked over and which are held by the points of the needles n' are
allowed to appear on the front face of the fabrics as loops.
2. For carrying out the above process a French circular frame, the needle-ring
of which contains needles with short and long points which latter do not engage the
binding thread and the covering thread during the knocking over of the latter but
throw them over their needles n¹ in the form of stretched loops (Figs. 2 and 5) while
on the other hand the presser wheels are suitably recessed so as not to press down
the needles n¹ provided with long points during the knocking over of the lining
thread and thus enable said thread to come under these points (Fig. 3) and to
appear as loops on the front face of the fabric suspended on the needles when it is
thrown off.
