Abstract
In a multiple-sheet monitoring device for sheet-processing machines, provision is made to arrange a number of sensing elements spaced apart from one another over the format width of the sheets to be conveyed or the sheet stream to be conveyed, and in this case all the sensing elements interact with the same switching element in order to stop the sheet-processing machine.
Claims18
A multiple-sheet monitoring device for a sheet-processing machine, comprising:
- a cross-member;
- a plurality of sensing elements disposed jointly on the cross-member and pivotally above and over a format width of a sheet and an overlapping sheet stream, respectively, at a spaced distance from the sheet and the overlapping sheet stream;
- a switching element disposed in a fixed position and being actable upon in accordance with a pivoting position of the sensing elements;
- and
- an adjustment device for adjusting all of the sensing elements in common to a thickness of the sheet and the overlapping sheet stream, respectively.

A multiple-sheet monitoring device for sheet-processing machines, comprising:
- a rotatable roller disposed underneath a sheet to be conveyed;
- a sensing element pivotally disposed at a spaced distance above the roller;
- a pivotable cross member;
- a switching element fixed in position, the switching element being actable upon in accordance with a pivoting position of the sensing element;
- and
- an actuating element for the switching element mounted on the cross member so as to be fixed against rotation relative thereto.
