" This‘invention relates generally to mechanism
forv wrapping any suitabler binding material
(hereinafter called twine) >aroundfa'cylindrical

mechanism embodying ' a.- 'twine- feeding- member
(hereinafter called a tube) operative to engage
the? twine to be fed therefrom with the material
passing. into Ythe machine whereby'the' end oí
thetwine is carried into the machine and around
the bale disposed therein.
'
Invv operating baling .machines it sometimes
happens due to'the lack offmaterial enteringthe
