Web twister removal apparatus

摘要

An apparatus for detecting and eliminating a twister in a running web of flexible material comprises a catch section (5) for twisters (22), which extends between a web guide gap (6) on the inlet side and a web guide gap (7) on the outlet side; a rotor (9), which is controllable in rotation about an axis parallel to the web running direction (4) and which houses the web guide gap (6) on the inlet side; a scanner arrangement (13) for detection of a twister (22) that has entered the catch section (5); and a control unit (12), which, upon detection of a twister (22) by the scanner and detection arrangement (13, 15), triggers the drive (10) of the rotor (9) for rotation of the web guide gap (6) on the inlet side and thus for untwisting the twister (22). <IMAGE>
