ABSTRACT:
A roll (30) of adhesive worked between two rollers (10, 12) of the gumming device is supplied by feed nozzles (34a, 34b) projecting fine streams of adhesive (35a, 35b) with monitored flow. In case of an increase in the measured viscosity of the adhesive or stopping of the machine on which the gumming device is used, a water-atomizing device (40) allows the viscosity to be reduced and prevents the adhesive from drying out. A dimension of the adhesive roll is monitored and controls regulation of the output of the adhesive-feeding nozzles. The gumming device thereby ensures proper gumming of a strip of paper (2).
