b each direct a focused laser beam 20 a and 20 b on a plurality of moving workpieces 14 a 14 c to produce a plurality of cut lines 16 a 16 c respectively a conveyor 22 or the like is used to move the workpieces 14 a 14 c successively past each laser beam as shown in the figure this embodiment represents a typical factory floor set up for the rapid production of workpieces for example plastic containers power to the lasers 12 a and 12 b is provided for and adjusted by a pair of power supplies 18 a and 18 b respectively similar to the embodiment described in fig2 each laser beam 20 a and 20 b is adjusted to remove a predetermined amount of material along the cut line 16 a 16 c while this embodiment shows the use of only two lasers depending on the workpiece material and the speed of the conveyor more lasers may easily be required to effect a clean high quality cut by using a plurality of optimized lasers each focused along the same cut line problems associated with laser cutting such as burn marks formation of bubbles and dross is substantially eliminated referring to fig4 where like features have like numerals another exemplicative embodiment of the present invention.
