This invention relates to an apparatus for knitting un
distorted looser stitches in selected portions of knitted
articles.

The coating material can be an oil, paraf?n dissolved
More particularly the invention pertains to an appara
tus for knitting looser stitches in the tops and/or other 15 in deodorized kerosene or other solvents, water-solutions
of glue or other sizing materials, etc., and can have any
portions of hose by spraying or otherwise variably coat

or at the input to the supply line 23 (which if carrying

Another important advantage devolving from this in

ever, machines set up to knit perfect (even) stitches in 25 vention, especially when practiced with an oil or other lu

the leg portion have proven incapable of knitting looser
stitches in the top without producing undesirably notice—

It is accordingly the principal object of this invention
