Improvements in Plaiting and Braiding Machinery
I, WAITER LUFT, of Barmen, Rhenish Prussia, 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
-
My invention relates to a braiding or plaiting machine and enables me to produce
at one and the same time, a flat lace or braid, plain or in ornamental or fancy work
character and also a solid round cord, twi ted and not braided and interlaced at
one side with the flat lace, or to produce a flat lace double lud and having at the
edge formed by this folding interlaced with it such a twisted cord as mentioned
or, to produce a flat lace as above, cariying on both edges interlaced to them such
1ound colds The flat lace may be of such a character as "mignardise
the edges formed in ornamental meshes and the twisted cord interlaced to these
meshes any such variations will be easily made by the experienced manufacturer
having once the foundation, that is, my invention in hand This is illustrated by
the accompanying sheet with drawings showing in
or have
Fig 1 a vertical section of the machine, following line I, II, III, IV of Fig 3
Fig 2 is a side view from the left of Fig 1
Fig 3 is a plan
Fig 4 and 5 show a diagram of the path the bobbins have to take during the
completion of the work
Fig 6 gives views of different variations of the product of this machine
The ordinary braiding or plaiting machine is modified in the following way,
in order to obtain the new machine, parts A A show a series of grooves with
discs and wheels as in an ordinary plaiting machine, but in taking the last disc
but one, B, belonging to this set it will be seen that here begins a notable
deviation from the known machine, this disc is brought into a horse-shoe form
by prolonging and continuing the groove to junction with the last or returning
disc of the flat braiding system, in arranging to both sides of this new path
the guiding or transmitting wheels D D for the shifting of the bobbins from B
through D to C and round to D and back to B and A A of the flat-braiding
system but on the other hand I continue the groove from C in opposite direction
to likewise in a horse-shoe formed prolongation to form communication with the
disc E, accompanied by the tro transmitters F F which form the connection
between C and E so that the discs B, C and E revolve in the same sense
Around E, I arrange in the example shown, three smaller discs G, H and I,
turning all in one direction, but in sense opposed to E
Consulting now Fig 3 in the drawing it is obvious that discs A A, B, C
together with transmitters D D' form a partial set of plaiting discs, which produces
the ordinary flat-lace, and that the discs C, E G, H, I, with guide wheels k F¹
are constituting a second partial set of plaiting discs, which produces a round
twisted cold, not plaited The disc C belongs as is seen, to both these partial
groups or sets of plaiting discs, and in diagram Fig 4 and 5 is shown, that disc C
with its groove is the cause of the interlicing of the thread of the flat-lace and
the threads of the twisted cord, the case represented shows in Fig, that each
Successive pair of flat lace threads is slung into one thread of the twisted cord at
colunin IV, corresponding to disc The path of the bobbins is the following
The bobbin-spindles of the group A A B C, follow the serpentine path A A A

page_text: and turn 1ound C in the passage from B to C the course has been deviated, for
the reasons described above, directly from B to C, and it is obvious that a return
of the bobbin-spindles to disc B after the return round C must be provided for,
giving them there the same position as if the serpentine path had not been
interrupted The arrangement of the two transmitters D D' in symmetrical order
already produces by itself this movement of the bobbin spindles in the required
sense
These arrangements have the following influence on the braiding of the flat lace
The edge to which the twisted cord is plaited on, shows, when it is opened out and
analysed, simply that difference in comparison with the other edge, that as stated
above there are always two successive threads of the flat lace interlaced to the
twisted cord laces, when on the other edge ench thread of the flat lace is bound
with the next one
The bobbins on the partial set or group for the twisted cord go from C right
over to E, from E to G where they complete one turn in revolving on their own
axis and returning to E back, they are guided to H whereon they make al o one
turn round and are brought to I to do the same again, and then they continue
again by E, are taken up by the transmitter E¹ which brings them forward to
again, where they next begin their course again as described On dises G, HI
is completed at one and the same time the necessary twisting of the threads of
those bobbin, which have their course over them and on disc no twisting is
accomplished on the contrary, during the circulation of the bobbin spindles from
the point of contact between Í and E in a ducetion towards C, then round
again to the point of contact between G and E there takes place a partial
untwisting of the last twist received on I but this of no importance
My new partial group ngement, consisting of the discs and grooved
paths EC, G, H, I, differs therefore from ordinary braiding machines for round
cords, so, that only on discs G, HI from all those that are grouped round E,
there is produced a twisting torsion whilst on dise C there is none, but half a turn
of untwisting is performed during the interlacing of the cord with the flat lace
made on the partial group A A A
B
The partial set of dises which makes the twisted cord can of course also be
added to the other side of the flat lace making, et of discs, at A, and will produce
then here also an interlaced and well jointed twisted cord on this edge of the flat
lace, so that the machine so alianged makes then flat lace bordered at both sides
by a twisted round cord-edge If it is desned to have the twisted cord thicker
and well filled, without spending too much of the more valuable threads on view,
there is no objection, to have a central cord of ordinary cheap material passing
through the centre spindle of 1 which will then be covered round by the twisting
threads on the outer surfice Likewise the machine shown on the drawings and
described heretofore can be combined to any known arrangement of braiding fancy
laces of the well known eye-let boidered lace for mignardise work, the
partial set of di cs or group for twisted cord can also be arranged in the middle
course of a flat lace braiding machine or rather between two partial sets of flat-
lace mal ing discs, in order to obtain a twisted cord interlaced to the folded edge of
the middle of a flat-iace
'
In general, there will be no difficulty now for an experienced specialist, to find
out a number of combinations and variations of lace goods, where the twisted cord
interlaced to the flat braids will form the basis and fundamental character of the
fabrics, a a consequence of my invention
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare, that what I
claim 19
A braiding or plaiting machine for the simultaneous production of a flat braid
or lace and a twisted coid, which both during their said production arc interlacing
with each other and which consi ts in such a disposition of discs in conibination

page_text: with the known system of discs for flat lace or braid that the last disc but one of
the braiding set of discs, B, is prolonged in horse-shoe shape and so joins the path
of the bobbins to the last disc C of the said flat braiding set by intermediate
transmitting wheels D D' and the combination of this last disc Č, playing the
roll of a transporter, and at the same time of a disc in another set of discs,
forming part of the machine, on which latter discs is produced a round twisted cord,
and which are communicating by the transmitting wheels F F¹ with the centre
disc E of this set of discs C EGHIF F' which form part of the machine
