conical bending:
Except for the top roller, all rollers can be moved in an inclined position for
conical bending. 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.
