The strip securing means 20 comprises a sleeve 22
made from a ?exible material such as paper, ‘fabric, etc.
The sleeve 22‘ is provided with a plurality of spaced
holes 24 extending therethrough at spaced points there
‘along. A limit stop 26 is provided to limit the extent
to which the strip of ?lm 18 may enter the sleeve 22.
This invention relates to a strip winding means, and
The limit stop 26 may be readily formed by folding over
an integral tab and adhesively securing the same within
the sleeve 22.
Heretofore, it has been conventional to secure strips 10
