Abstract: A laser enclosure is provided including a housing having an inner cavity in which laser operations are capable of being performed and a section having an opening through which workpieces pass into and out of the inner cavity. The enclosure further includes a workpiece positioner rotatable about a generally horizontal axis for moving workpieces from a workpiece loading and unloading zone, through the opening to a work zone within the inner cavity. The workpiece positioner includes a first workpiece holder adapted to releasably receive at least one of the workpieces. The enclosure also includes passive sealing apparatus movably coupled to one of the section and the workpiece positioner via a slide attachment device for sealing at least one portion of the section to at least one portion of the workpiece positioner to inhibit laser energy from exiting the housing through the opening.

Abstract: A laser enclosure is provided comprising a housing having an inner cavity in which laser operations are performed. The housing includes a first section having a first opening through which workpieces pass into and out of the inner cavity. Further provided is a first workpiece positioner for alternately moving the workpieces from a first workpiece loading/unloading zone, through the first opening to a first work zone within the inner cavity of the housing. The first workpiece positioner includes a first workpiece holder adapted to releasably receive at least one of the workpieces and is movable from the first workpiece loading/unloading zone to the first work zone as the first positioner moves from a first loading/unloading position to a first work position.
