Abstract
To permit triggering a torn web capturing roller system (9, 10, 11) or a web deflection unit (28) for rapid capture of a torn or damaged web (7) in a printing machine system having a printing station (2) and thus prevent wrap-around of torn webs about elements of the printing station, the web is guided about a cooling roller or cylinder (14) downstream of a web dryer and strain between and cooling roller and the side wall of the printing machine is measured. This strain is measured for example, by a piezoelectric tranducer or a strain gauge (23) coupled to a bearing (21) in a side wall (19) in the printing machine. The signal from the transducer (18), for example the strain gauge (23), is evaluated in a computer and control unit (26), for example with respect to a reference. The reference can be modified, if desired, by entering in the computer or control unit data representative of acceleration and deceleration of the machine, per square weight of the web, weight of the cooling roller or cylinder (14) and the like.
