Abstract
The spooling machine for continuously running fibers has a housing (1) with a support arm (2) extending from its upper portion; spindles (7,8) for fixing a number of bobbins (11) for the continuously running fibers; a rotatable spindle revolver (4) on which said spindles are rotatably mounted; a changing device (14) including changing units (15,16,17) corresponding in number to the fibers; respective variable speed motors (9,18) for rotatably driving the spindles (7,8) and the changing device (14) and a control unit (20) mounted on a free end of the support arm (2). In order to avoid electrical interference between the frequency converters and other electronic equipment each of the variable speed motors for the spindles and the changing device have an integrated frequency converter (9a,18a). The control unit (20) controls momentary frequencies of the frequency converters and also spooling machine operations.
