Abstract
Abstract A device for substantially increasing the efficiency, output and quality when treating workpieces by means of laser energy, particularly when welding or boring workpieces, wherein the laser beam from one single laser source is subdivided into a number of individual beams for simultaneously treating a number of places of one or more workpieces.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
17 words
Apparatus in accordance with claim 1 wherein said beam splitting and redirection units are two in number.
Claim 2
Dependent Claim
33 words
Apparatus in accordance wIth claim 1, wherein the means for displacing said carriages of each beam splitting and beam redirection unit are driven from a common source, whereby said carriages are displaced simultaneously.
Claim 3
Dependent Claim
56 words
Apparatus in accordance with claim 3, wherein said beam splitting and redirection units are three in number and said axes thereof are coplanar but extend at oblique angles with respect to one another, whereby the loci of the focused subbeams at said workpiece define circles of radii in accordance with the displaced positions of said carriages.
Claim 4
Dependent Claim
83 words
Apparatus in accordance with claim 3, wherein said subbeam reflection means comprises a rotatable reflector; and said means for adjusting the angular orientation of said reflection means comprises a linearly rising cam surface extending along said axis, and an arm connected at one end thereof to rotate the axis of said reflector, the other end of said arm having a cam follower engaging said cam surface, displacement of said carriage moving said follower along said surface and rotating said axis and said reflector.
