ABSTRACT:
A suction drum has an air-permeable shell and is rotatable about a first axis. A rotary disc is rotatable about a second axis, which crosses said first axis and is spaced therefrom by a distance which is equal to one to two diameters of said drum. Said rotary disc has a generally flat side face that is almost tangential to said shell and defines a tapering gap therewith. Suction means are disposed in said drum and define on said shell an air-permeable suction zone which adjoins said tapering gap. Means are provided for supplying flying fibers into said gap into contact with said suction zone and said side face. Drive means are provided for rotating said drum and disc in such a manner that fibers in contact with said drum and disc are twisted together to form a thread. Thread-withdrawing means are provided for withdrawing said thread in a direction which is approximately parallel to said first axis while holding said thread against rotation. Said drive means are operable to rotate said drum in such a sense that said drum moves generally toward said thread-withdrawing means adjacent to said gap.
