A laser processing unit (10) includes a workpiece loading station, and a laser workstation (14) having a laser robot that performs a laser operation. A flexible endless loop extends from the loading station through the workstation for delivering a workpiece from the loading station to the workstation. A first stationary wall section separates the workstation from the loading station. A second stationary wall section is offset from the first stationary wall section. A first movable door (58, 60) is configured to form a laser light-tight seal with the first stationary wall section. A second movable door (58, 60) configured to form a laser light-tight seal with the second stationary wall section. A seal projection (68, 70) is attached to the flexible endless loop. The seal projection (68, 70) forms a laser light-tight seal with the first movable door (58, 60) when the workpiece is located in the loading station and forms a laser light-tight seal with the second movable door (58, 60) when the work- piece is located in the workstation. |
