The roller positions can be read on display instruments. For semi-automatic or fully automatic operation of the machine, the bearing jewels of the rollers are equipped with scale bars and slide cams for limit switch actuation. This allows the rollers to return to the same set position over and over again, giving a very high level of uniformity in the shot wefts being bent.
