Title:
DEVICE FOR SPOOLING A THREAD
Document Type and Number:
WIPO Patent Application WO2004031060
Kind Code:
A3
Abstract:
A device for spooling a thread on a bobbin (1) is disclosed, whereby a thread guide unit (2) is provided for guiding the thread, which is moved axially. The thread guide unit (2) is connected to a hollow shaft motor (12) as drive means. The hollow shaft motor (12) comprises a driveshaft (11) which sets the thread guide unit (2) in a reciprocating motion with reversal points at a desired speed, dependent on the control of the hollow shaft motor (12). The hollow shaft motor (12) is suitable as a particularly simple embodiment of a drive means for the thread guide unit (2). Further advantageous embodiments concern the sealing of the driveshaft (11) relative to the housing of the hollow shaft motor (12). An airflow in the direction the driveshaft (11) away from the hollow shaft motor (12) is preferably generated in order to prevent ingress of dust into the hollow shaft motor (12).
