d) a set of circumferentially spaced nozzles each
including a tip having an axis generally disposed in a radial
plane of the drum, the plane including an axis of drum rotation;
e) the tips each being disposed within an imaginary
cylindrical extension of the surface extending outwardly from the
side edge in a direction away from the remote side; and
f) the tips each being oriented to direct a flame
toward a side of the drum and the cylindrical extension at a
location near said edge whereby to impinge on superposed,
juxtaposed edge portions of a web projecting from the surface
past said side edge.
22. A process of converting a clear polyethylene web folded
treated surface to treated surface as steps in the manufacture of
sleeve labels comprising
a) feeding the web along a path from a supply to and
around a hardened cylindrical roll while rotating the roll at a
surface speed equal to the lineal speed of web feed;
b) biasing a score cutter against the web as it
passes around the roll thereby flush trimming edge portions of
the web remote from the fold and tacking the edge portions
together;
c) feeding the trimmed web over a large drum having a
cylindrical surface web engagement section while rotating the
drum to produce a surface speed of the section equal the lineal
speed of web travel;
d) causing said trimmed portions to project outwardly
past an edge of the section as the web is fed over the drum;
