inserted it into the temple. Using a screwdriver, the operator
partially tightened the temple screw, fully tightened the lens
screw, and fully tightened the temple screw. The operator
repeated the templing process with respect to the other temple.
If the operator had applied too much pressure to the screws when
tightening them, the following damage, any of which would have
made the affected part unacceptable, might have occurred: (1) A
cracked lens, (2) a chipped lens, (3) stripped or chipped screw
head, (4) stripped screw threads, (5) stripped threads inside the
temple or endpiece holes, and (6) broken solder on the endpiece.
Following completion of the lensing and templing procedures,
the operator inspected the sunglasses for any damage to the parts
that occurred during the assembly process and replaced any
damaged parts identified.
The operator inspected both the left and right lens for lens
gaps (i.e, a gap between the lens and the frame). If the oper-
ator had identified a lens gap, the operator would have adjusted
the curvature of the frame by manually bending the frame to meet
the curvature of the lens. B&L Ireland and B&L Hong Kong fre-
quently encountered lens gap problems with respect to a style of
metals called Caravans that had square rather than round eye-
pieces. This was because the curvature of the top of the Caravan
frame generally failed to meet the curvature of the lens. At B&L
Ireland, operators were responsible for adjusting the curvature
