This invention relates to yarn winding and
reference numerals refer to the same or similar
packaging machines, and relates more particu
elements in the respective views.

By grinding the face 32 of gauge 28 to a cer

on the package by the striking of traverse bar 25
against gauge 28 to halt the winding operation
‘when the package has reached its predetermined
size. To produce the desired results we have
found that the face 32 should have an angle of
slope which ranges from 121/2 degrees vertical
and 30 degrees horizontal to-1'71/2 degrees vertical
and 25 degrees horizontal, highly satisfactory re
‘sults being obtained when the angle of slope of
face 32 is 171/2 degrees vertical and 271/; degrees
horizontal. It is preferable that the face lie in
a single plane. The angles forming the slope of
the striking face lie and are measured as shown
in Figure 5 of the drawing, the horizontal angle
