ABSTRACT:
A method and an apparatus for indicating suitable binding times for a file or files placed in a file binding apparatus. The suitable binding time is comprised of the time (t.sub.0 -t.sub.2 ; t.sub.3 -t.sub.5 ; t.sub.6 -t.sub.8) required to heat the heating plate of the binding apparatus to a predetermined maximum temperature governed by the switch-off temperature (T2) of a thermostat, and the time taken for the heating plate to cool to a similarly predetermined switch-on temperature (T1) of the thermostat, determined by a lower temperature. The suitable binding time is determined by utilizing the switch-off and switch-on temperatures of the thermostat, wherein the thermostat output signal controls an indicating device which indicates the aforesaid suitable binding time.
