                <div dir="ltr">For a stage illusion, I would like the
                  ability to lift a black curtain from the floor,
                  approximately 8' wide x 4'-6" high, to hide some
                  activity on stage.</div>
                <div dir="ltr"><br>

                <div dir="ltr">We currently have a black-out on that
                  side of the stage, but lighting on the other side of
                  the stage provides enough ambient light, that the
                  stuff I want to hide is visible if you are looking. Of
                  course, the activity on the other side does distract
                  the audience, but I am hoping to improve the
                  situation.</div>
                <div dir="ltr"><br>

                <div dir="ltr">I can have items preset on the stage
                  floor. My current thinking is to have some actors, who
                  will be on that side of the stage, lift up an 8' long
                  pole that has the curtain. Then, drop it at the
                  reveal. But, we prefer that those actors leave the
                  stage in the blackout.</div>

                <div dir="ltr" data-setdir="false">I am wondering if
                  there might be a way to mechanize this temporary
                  masking. I can't use any rigging from above in this
                  part of the stage. Nor can I do anything to the stage
                  floor or use a trap.</div>
                <div dir="ltr"><br>
                </div>
                <div dir="ltr">The masking comes up in relative
                  darkness, so human assistance in that aspect is
                  acceptable, if I cannot motorize it.  It should go up
                  within 3 or 4 seconds, but should drop very quickly.</div>

                <div dir="ltr" data-setdir="false">Attached is a PDF
                  with some ideas.  One mentions the idea of a motorize
                  tape-measure type device. Is such a thing available? 
                  I welcome comments.</div>
