Range of application (Order code):
Double sheet detection UDC-18GM-400-3E3
Applications:
■ In printing machinery, where the ultrasonic double
sheet control protects the complex mechanics from
damage and prevents a second sheet from lodging
in the machine, by avoiding the situation in which
two sheets are drawn into it.
Additional application through series 18GM35:
■ In the control of adhesive films in label making
machines, in which the application of the films to a
carrier material can be detected and counted.
■ In letter opening equipment, where the complete
emptying of the opened envelope is controlled.
■ In receipt and voucher counting machines, in which
the ultrasonic double sheet control ensures that
bank receipts are not counted incorrectly.
■ In packaging machines, in which the jointing posi-
tions for the connection of an aluminium packaging
film to the beginning and the end of a sheet are
detected and the running speed of the machine is
adjusted accordingly.
■ In paper processing machinery, for the detection of
air, single and double sheets and/or jointing
positions.
■ In paper sorting systems in the manufacture of
calenders – no “month” must be missing or
inserted twice.
