Abstract (en)

[origin: JPH01168453A] PURPOSE: To facilitate operation of a printing plant without interrupting web feed unnecessarily by actuating a web interrupter when a web is torn to cause an angular deflection of the web which may damage the printing plant. CONSTITUTION: In order to protect a printer against damage, a web interrupting means 5 is disposed between the final print unit 1 of a printer and a dryer 3. The web interrupting means 5 has a grasping jaw 6 and/or a knife 7 which acts upon displacement of a web 2 to grasp or cut off the web 2. A slot 9 for passing the web is located on the inlet side of an inlet slot 10. The web interrupting means 5 us also provided with a web tear detection switch 11 disposed closely to a cylinder 4 for displacing the web 2 when it is torn.
