Abstract:
A spinning machine having a plurality of spinning stations, each spinning station comprising:a feed drum to transport a fiber band into said spinning station for processing into a yarn; an individual feed drum drive operably disposed to said feed drum, said feed drum drive rotating said feed drum at a specified rotational speed; a disintegrator roll operably configured with said feed drum, said disintegrator roll interacting with said fiber band in a manner that separates said fiber band into individual fibers; a rotor rotatable at a specified rotational speed, said rotor disposed to receive said fibers separated by said disintegrator roll, and spinning said fibers into a yarn; a withdrawal roll operably configured with said spinning station, said withdrawal roll removing said yarn formed in said rotor; a spool roll operably configured with said spinning station, said spool roll winding said yarn removed by said withdrawal roll on a bobbin operably disposed to said spool roll; wherein at least one of said withdrawal roll or said spool roll possesses an individual drive operably disposed to said respective roll, said drive rotating said respective roll at a specified rotational speed; and wherein said rotational speed of said individual feed drum drive and said rotational speed of said other individual drive are controlled by a preset rotational ratio such that a change in speed of one drive results in a corresponding change of speed in the other.
