MACHINERY OR APPARATUS FOR SIZEING OR DRESSING YARNS OR THREADS."
This Invention has for its object, when sizeing or dressing yarns or threads of
different colors, or partiy white and partly colored, to prevent the communication
of color from yarns or threads of one color to those of another color, or to the
white yarns or threads in a more complete and better manner than hitherto; and
it is of especial importance when white yarns are used along with colored yarns,
as white yarns slow slight colorations very easily, and it is always desirable to
keep them as clear as possible.
In carrying out the Invention what is known as "tape" sizeing machinery is
employed, and the parts of it are specially arranged or constructed in such a
manner that, for example, in the case of white and colored yarns the coloured
yarns are dried to a certain extent before they become combined with the white
yarns, or vice versa. It is not new to separate differently colored portions of
the yarns composing one warp, and to pass such portions through different size
or dressing boxes, but hitherto all the warps have passed together upon the drying
cylinder and have become united whilst still in a very moist condition, so that
color has been easily communicated from some yarns to others. In altering a
machine having a single size box so as to introduce the present improvements the
size box is set further from the drying cylinder, and the yarns which are passed
through this box, and which are the colored yarns in the case of a combination of
white and colored yarns, are in one modification led downwards from it and over
or in the neighborhood of a box or pan heated by steam or hot water, and are
subjected to the action of a rotating brush and of a fan. The colored yarns are
next, by means of one or more suitably placed guide rollers, led upon the drying
cylinder at as low a part as is conveniently attainable on the rising side of it. An
additional small size box is provided for the white yarns, and in one modification
is placed at a slightly higher level than the other size box, and a little nearer to
•

separate beam, and passing from it to the drying cylinder, so as to meet the latter
at a high part considerably separated from the part where the colored yarns meet
it. A rotating brush acts on the white yarns between their size box and the
cylinder, and a fan may also act on them.
The additional size box is fitted with a partially immersed roller arranged on
conical centres or on antifriction wheels so as to turn as easily as possible, and so
that the white yarns can turn it in passing over it even when in comparatively
small quantity. The box may be placed near the outer side of the other size box
instead of being between it and the drying cylinder.
In other modifications the white yarns are led first upon the drying cylinder so
as to be dried to some extent before the colored yarns join them; and for this
purpose the white yarns are led under instead of over the size box of the colored
yarns, the additional small size box being a little nearer to or a little further from
the drying cylinder than the other size box.
