Abstract
A sheet binding apparatus, for attaching loose sheets to one or more folders, has a completely automatic binding process after insertion of the folder(s). This is carried out by a heating assembly, the current supply to which is controlled by a micro-processor having inputs received from a starter device of light detector type, a temperature detector device of thermistor type and a timer device. The timer device is activated by the micro-processor when the temperature detector device indicates working temperature at the heating assembly. In one aspect of the binding process it is also related to the thickness of the folder(s) to be bound. This is carried out by a current control device acting on the supply circuit for the heating assembly in such a way that the thicker the folders inserted, the more current is allowed to the heating assembly.
