From the foregoing description it is apparent
that the instant invention provides an apparatus
in the form of an attachment which may be
quickly ,and expeditiously attached to a sewing
machine, irrespective of its make, and whereby
a folded trimming may be produced substantially
automatically.
‘
.
As herein described, the mechanism for feed
ing the material and product formed'therefrom
is disposed laterally of the, needle andit may
be disposed at any position with respectto the
folder.
Since it is obvious that various changes and
modi?cations may be made in the above descrip
ing a presser foot cooperating with said feed dogs,
means to adjust said presser foot relative to said
feed dogs, said arm being adapted to be con
nected to the four-motion feed-actuating mecha
nism of the machinewhereby said feed dogs will
progressively pull the material. through the folder
and/feed the‘folded material to and away from
said needle, through said means to turn the
stitched material inside out, and from :the machine.
