My invention relates generally to means for
clipping‘ and trimming furs; and an important
object of the invention'is to provide means where
which are adapted» to'register ‘with the opening
de?nedby the suction’ pipe ?anges 9 and ID as ,
they come into registry therewith. ‘ The shaft 13
by the fur skins are exactly held While‘ being car- > extended beyond its supporting lug ‘land has a
pulley l'lrthereon which may be driven'by a suite 5 '
5‘ ried past a setof revolving knives which clip the‘
hair to any set length, whereby complete and ac
curate trimming of the skin is achieved in one
'ablevb_elt"(notshown) for revolving the cylinder

In the embodiment of the invention shown in

perforated over its’ entire width- and length or‘
circumference,‘ but may be perforated only in 39;
such portions, thereof as necessary to carry the
leading edge ofthe skin past the clippingknives
or cutters; the remainder ofthe' skin being then
held to the cylinder or belt by the spring pres—
sure ?ngers 35. Where-more than one type’ of
work is tobe done by one machine,.shields of
impervious material may be applied to a com-v
pletely perforated cylinder or belt to’ close off
the undesired perforations.
