That appears to be a low-end machine. Have you asked your
question of Brother?
http://www.brother-usa.com/Support/
I know the Endless Bobbin feature for my Singer Quantum
XL5000 is an integral part of the machine, not an add-on.
It require a special bobbin and threading path using a large
cone of bobbin thread.

It does not and you can not add it to a machine.

That link explains to me (at last) how the "endless bobbin" feature
works. It doesn't feed the thread continuously into the bobbin area, it
automatically refills the bobbin once it's empty.
As such it would need a special design of bobbin, an automatic threader
to feed thread to an empty bobbin, a drive to wind the bobbin, a cutter
to cut off the thread once the bobbin is full, and another threader to
start the new thread. All of this has to get out of the way before
sewing can begin, as the fundamental principal of the lockstitch sewing
machine is that a loop of the needle thread passes right around the
bobbin or shuttle.
I can't see this ever being an add-on feature, and would expect it to be
found on top-of-the-range machines only.
I wonder how industrial machines get around the bobbin capacity issue?
A winder like this, or maybe an automatic bobbin changer and a supply of
pre-loaded bobbins?

No, typically they use either HUGE bobbins (compared to domestic sewing
machine bobbins), or two cones of thread, one of which is fed in under
the machine bed through what would be the bobbin area on my machines. :).

That is exactly right. The special bobbin has a small gear
on its bottom which turns the bobbin during the re-fill.
The supply cone of bobbin thread, having been threaded
though a complex series of hooks and pins under the pop-up
plate just above and to its left, sits quietly in its
location to the right of the bobbin area, and waits for a
signal that the bobbin thread has run out. The embroidery
process then stops, the machine runs the hoop in a large
square until *all remaining* bobbin thread is pulled out of
the bobbin, then slowly starts the bobbin spinning until it
catches the end of the supply thread in a little hook on the
bobbin and winds it tightly around the axel. Once it
catches, it re-winds the bobbin *in place*, without having
to remove the hoop or take out the bobbin.

Yes, exactly! ;-) The special bobbin does NOT take as much
thread as a standard bobbin. It has a tiny gear on the
bottom and a cross-section of its inner part is shaped more
like a "><" then an "H" (imagine that turned 90 degrees).
The path of the supply thread to the bobbin is... complex.
It requires a special little plastic "thingy", (that's a
technical term) which snaps into place once the small door
just above and to the left of the large cone is opened, and
one pulls the supply thread over and around a bunch of
positions in the "thingy", which feeds the thread into and
around a series of hooks and pins. It can be done without
the "thingy" but the "thingy" facilitates the process. ;-)

Yup.

It is the main feature for which I selected the Singer
Quantum XL5000 , purchased for $2,6000US (on close-out
sale!) in 2004!
I think there may be Brother's machines which have a similar
feature. A google search on "Brother's Endless Bobbin"
brings up some hits. But I cannot locate any models on the
Brother.com site with use that specific terms. Their specs
talk about things like a bobbin "FAST system", "Super Easy
System", "Super Easy Bobbin Winding System", etc. One
model, the Innov-is2500D says it has an "Automatic" bobbin
winding system, perhaps that's the endless bobbin OP is
looking for?

I wonder, too. Maybe someone with an industrial will jump
in here.

A handful of manufacturers long ago actually made two spool sewing
machines, which utilized an actual spool of thread instead of a
bobbin. Natinal made them, as did Eldridge. Here's one of them:

There must be a downside: I expect it can't sew very fast, moving a
whole reel back and forth and needing to make a big loop of the needle
thread to get it over the reel/bobbin. But a great idea if you've got a
lot of one colour of seam to do.

with a continuous feed (like a serger) the machine can only do
chainstitch, as far as I can tell.

Here is a line drawing of the endless bobbin:
http://www.sewshop.com/SINGER_Quantum_Bobbin___2_Pack-9-4216-75.html
I have four, one is always ready for white, one for black,
and the other two I use occasionally for a thread color to
match the fabric, as in the case of the dragonflies I'm
doing on a throw.
http://ickes.us/Dragonflythrow.aspx
Since both sided of the design will be visible, I decided to
put purple in the bobbin. I perhaps I *should* have put a
new bobbin with matching thread in for each of 8 color
changes...
Nah. ;-)

No, most industrial mchines sew at several thousand stitches per inch as
opposed to the low hundreds of most domestic machines. Some of the
newer larger embroidery machines (like that amazing Bernina I'll buy
when I win the lottery!) have a bigger bobbin and sew at 1100 SPM.

Yes, those ones usually do a chainstitch. It works until a thread pulls
loose!

???!!! Really? Doesn't that sort of pile the stitch right
on top of each other? ;-> (I know you meant stitches per
minute.)

The Singer Quantum XL5000 top speed is "up to 850SPM," but
for most embroidery projects I slow it down to about the 3/4
mark. For the metallic thread I used recently, I slowed it
down to the slooooowest speed to prevent friction and thread
breakage. I now have a bottle of All-Purpose Sewer's Aid
(thanks Judie!), but I have yet to test it.
I run my sergers as fast as they will go. ;-) The old
Bernette really whizzes, the Huskylock 936 is much slower
even at the fastest setting. <shrug>

My 910 was very fast. The Bernina is too. The Brother is slower, and
the only Bernette I ever used didn't get to be too fast before it
shimmied off the table into my lap!

Yeah, my bad, I suspected as much, I should have left it
alone, sorry! :-} Have fun with the other half of the hem,
AFTER you get some rest.

How strange. I love the little Bernette, it goes like
greased lightening and does not vibrate or "walk" at all. I
also like that the cutting blade is so much closer to the
needle, so I can do curves with much more precision.
The Huskylock 936 on the other hand, is slooow at its
fastest setting, and vibrates *a lot*. It would leave the
room if it could get away with it. Maybe it needs
servicing, although it's only 5 years old, and it has been
this way since it was brand new.

Alan,
You are correct the industrial machine that have what is being called here
endless bobbin are indeed chainstitch machines.
Industrial machines sew MUCH faster than home machines even the ones with
the large capacity bobbins.
Alan Dicey
Thanks for the information, Ron, I'm glad to see my guess was right. I
did think that anything working on an industrial scale would have to
work faster, too.

I would haz the tired too!!! If I'm having a really bad day, DD tells me

Just finished that hem, the re-stitching of the bottom of the internal
support, and the tops of the 4 godet pleats... About to do the bones
and cover some buttons... LOTS of tiddly little buttons!
I haz the sore paws and the numb head. No brains, all dumbs here!

If the buttons are to used with loops up the back, I'm
cheering!!!
Nothing says "high-end bridal gown" like working
button-and-loop closure.
