Planetary-gear drive for looper |
摘要 |
A looper has a fixed support carrying a plurality of guides and a movable support carrying a plurality of guides, with a strip being looped back and forth between the guides of the two supports. The movable support is connected via a cable or chain to a winch carried on a rotary output member of a planetary-gear transmission having two inputs. One of these inputs is rotated continuously at a predetermined speed while the other input is rotated at a variable speed determined by the rotation rate of the output member.
