- 40 - In addition to assembling metals, B&L Ireland's personnel assembled plastics. B&L Hong Kong did not perform any operations that resulted in plastic sunglasses and did not even sell many B&L plastic sunglasses assembled outside B&L Hong Kong. This was principally because the bridge on the plastics was too wide for the average Asian face, which tended to be smaller than the average Caucasian face, and, unlike metals, plastics did not have nosepads that could be adjusted to fit the Asian face. In assembling plastics, B&L Ireland's personnel used a heating tunnel equipped with temperature and speed controls in order to render the plastic fronts sufficiently malleable so as to permit the insertion of the lenses and the formation of the headcurve of the fronts. The heating tunnel, which contained a conveyor belt running through the machine, heated the front with electrical elements located on the top of the tunnel. Although the specifications for a particular SKU established initial settings for the temperature and speed, the operator was respon- sible for adjusting those controls as necessary to facilitate the lensing process. If a front had not been hot enough when it exited the tunnel, the operator could not have inserted both lenses without damaging either the fronts or the lenses. On the other hand, if the front had been too hot when it exited the heating tunnel, it could have suffered heat damage such as sunkenPage: Previous 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 Next
