arm of the carriage may be designed in a C-shaped man

of the transverse arm in such a way that the individual
bobbin will be arranged without spindle. Furthermore,

easier than the ordinary working position of the bobbins.
For instance, the upper transverse arm of the carriage
shown on the left-hand side of FIG. 4 may in itself cor
respond to the simplest construction of a carriage. In
this way, a single row of individual bobbins for one
machine side may be mounted on a creel.
The supporting carriage 18, illustrated on the left hand
side of FIGURE 4, comprises a C-shaped holding arm,
the upper transverse leg 19‘ of which, as well as the lower
transverse leg 20, supporting each a bobbin holder 21
respectively suspended thereon. In this way, two indi
vidual bobbins can be mounted in suspended manner one
provided with a suitable guiding pro?le.
Preferably, such materials are of metal which, on one
hand, is resistant to the usual humidity in a spinning
plant, and, on the other hand, will have as sm0oth a
surface as possible in order to cut down to a minimum
the possibility of dust or lint collecting thereon.
The C-shaped arm 18 shown on the left hand side of
FIGURE 4 for the mounting of two suspended individual
bobbins may, in almost identical shape also be employed
for the spindleless mounting of an individual bobbin.
This is possible without dif?culties if, instead of the il
lustrated bobbin holder 21 supporting or bearing means
(e.g. members 33 of FIG. 11) is provided for the upper
end of a bobbin sleeve and if the free end of the lower
