ADVANTAGES OF THE ROBERTA
ELECTRONIC SPINNER
1. The flyer tension can remain set for days of use, with
no further adjustments being necessary. This tension device governs the rate of
fibre pull-in, to the spinner during the drafting. Because there is no friction drag in the
steel orifice piece groove of the flyer, it never changes with its use. The
loading from the tension spring is transferred through to the inside of the
flyer bearing hole. This is where the flyer fits into the bearing, or support.
Because this is always lubricated there, it always keeps the tension as was
originally set.
2. There is little need for
adjustments to the bobbin speed or tension settings regardless of how big the
diameter of the bobbin grows in size. This is a big advantage over other brands
of spinners. Observe the size of the
jumbo bobbin on the Roberta. Little or
no adjustment is needed as this grows to full size from the very small spindle
centre.
3. The electronic design ensures whatever performance is set on the
controls; it will continue to stay that way regardless of how hard you hold
back in drafting. The electronics also protects the motor from wear and tear.
This is not the case for electric spinning
wheels, were motors will burn out usually within 5 years of constant use.
4. More yarn control. A. A speed control on the driven bobbin, for the
twist rate. B.
More or less tension applied to the free turning flyer, will regulate
the draw-in rate. C. You can change the overall degree of
hold back in the drafting against the pull, to create a different yarn. The design on the top of the Roberta is the
same system as used in modern mills today (the only difference is their design
it is vertically constructed).
5. Good results are still
possible, even with irregular drafting from the hands, because of the ability
of free turning flyer to change its speed.
This makes it self regulating for the creating of an even spun yarn. If you pause and hold in the drafting, the
free turning flyer will increase in speed until it is the same speed as the
bobbin. In this situation, nothing will
gather, or load on the centre of the bobbin. The twist will continue, but the
yarn will not break. When you are ready
to go again, you can do a long draw to take up the additional twist, and this
will self regulate from your fingers through to the bobbin loading.
6. The long lasting motor is protected
from any damage by the electronics design.
Motor guarantee is for 10 years, even when being used for a constant
commercial use.
7. The working bobbin is quick
and easy to remove. Lift off the drive
band with one finger and then tilt the flyer and withdraw the bobbin off the
free end of the flyer.
8. Reeling off after the plying
is easy - just lift the drive band off with a finger, to roll off the finished
yarn to a niddy noddy, or a skein winder.
9. The Combo version has an
advantage in plying. The jumbo bobbin
holds the volume of the two of the regular bobbins. The 2 regular bobbins when
plied will fit onto a jumbo bobbin, without the usual stopping and joining.
10. High speed plying is
possible without any hard treadling work.
11. No top equipment changes are
necessary to create different types of yarns.
No need to worry about pulley or whorl ratios. Makes thin lace yarn through to heavy rug
yarn, easily.
12. The Roberta Spinner is built
to a professional quality standard, and is suitable for production yarn making,
as well as for the beginner. For the beginner there is no need to worry about
foot and hand co-ordination. In production spinning, it has been known to be
used every working day (all day use) for eight years before any servicing was
necessary. Even then after that amount
of time, only the top parts were reconditioned.
13. Very practical sliding hook
on the flyer arm. Use it both ways -
backwards and forwards. Use thumb and
forefinger for an easy quick change on the O ring to create a new bobbin
loading position. Very quick and easy to
do, and it saves time. You do not have
to wonder which flyer hook you were on, as would occur on conventional flyers.
14. Handy threading hook holder
is fitted to the side of the spinner, so it is always handy and is never lost.
15. Use the optional pause
control to maintain both hands on the fibre. Stopping and starting is so
comfortable. No need to vary any speed
set on the spinner when starting up again, because of the self regulating and
free turning flyer.
16. Variable motor (or bobbin)
speed is not necessary because of the automatically changing speed of the flyer
when you hold back against the pull. The
motor speed determines only the twist rate, not the pull-in rate during
drafting, as occurs on other brands of spinners.
17. For maximum portability, use
the 12 volt dual power input with the auxiliary cable. This cable can go to a
car cigarette lighter fitting, a rechargeable 12 volt power pack, or even a
small solar panel.
18. Uses only the power of a
household light bulb (40 to 60 watt).
19. The Roberta is light and
portable. It is extremely versatile in its use.
It makes any type of yarn from any type of fibre. Use the specially made
carrybag for easy moving around.
20. Nice wood finish to the
Roberta Spinner, which complements its professional performance. The “Roll
Royce” of spinners without the high price tag.
21. Originally designed for the
disabled or for people who have leg troubles.
It has been so popular over the 34 years of its production (year 2007)
that 95% of sales now go to ordinary people, who have discovered its
advantages.
