Abstract
A detaching method of sheets from a stack of sheets from a stack of sheets and a relative detaching apparatus is disclosed, including at least a gripping head of a handling device of sheets and a nozzle assembly apt to eject an air flow to a lateral edge of a stack of sheets, furthermore including: a storage assembly of pressurised air provided at least with a compressed-air tank equipped with a pressure multiplier and a relative first pressure adjuster; and a high-pressure pipe between the nozzle assembly and the storage assembly intercepted by a fast-opening electrovalve. The nozzle assembly is provided with a nozzle, supplied through the electrovalve, configured as a convergent/divergent spout.

Detaching apparatus (A) of a stack of sheets, comprising at least a gripping head (T) of a sheet handling device (L) and a nozzle assembly (1) apt to eject a substantially horizonal air flow toward a lateral edge of a stack of sheets, further comprising:
- a pressurised-air storage assembly (2) provided at least with a tank of compressed air (16) provided with at least a pressure multiplier (17) and a relative first pressure adjuster (18),
- an inlet port of said storage assembly (2) being connected to an air supply line upstream of said pressure multiplier (11) a high-pressure pipe between said nozzle assembly (1) and said storage assembly (2) intercepted by a quick-opening electrovalve (12),
- said nozzle assembly (1) being provided with a nozzle (5), supplied through said electrovalve (12), configured as a convergent/divergent spout (5c).
