Abstract: A rotary laser engraving device for retaining and rotating an object for engraving includes a frame, a first support assembly and a second support assembly mounted on the frame. To support the object the first support assembly includes a set of driven rollers and the second support assembly includes a set of free rollers, each being diagonally offset from the frame. The second support assembly is configured to slidably move on the frame to vary a longitudinal separation between the driven rollers and the free rollers. The second support assembly further includes a vertical adjustment assembly configured to move the free rollers vertically to vary a vertical separation between the driven rollers and the free rollers. In some aspects, the first support assembly also includes a fixed vertical adjustment assembly configured to move the driven rollers vertically to vary a vertical separation between the driven rollers and the free rollers.

Abstract: A rotary laser engraving device for supporting and rotating an object to be engraved during a laser engraving process is provided and includes a support frame. The support frame may include a central bar, a stationary vertical post and a movable post movable along a length of the central bar. A first support assembly is movably mounted on the frame, such as on the stationary vertical post, and includes a first pair of rollers for supporting a first end of the object to be engraved. A second support assembly is movably mounted on the frame, such as on the movable post, and includes a second pair of rollers for supporting a second end of the object to be engraved. At least one longitudinal adjustment mechanism and at least one vertical adjustment mechanism are carried by the frame and allow to adjust the longitudinal and vertical separation, respectively, between the first and second pairs of rollers.
