Semi-auto:
You can check above Manual, Semi-auto leader and trailer video, for semi-auto leader and trailer, there is no need to cut a large piece of ribbons when you stick leader/trailer, but for manual table, you have to cut a large piece of ribbon which will be throw away when you stick leader/trailer, it is big waste and cost much for high value ribbon. All of our standard TTR slitter are with Semi-auto leader and trailer with this ribbon saving function.
In the middle , a piece of ribbon is cut.
