1. A tool change device (12) for a working apparatus (10) of longitudinal shearing machines adapted for working on paper, cardboard, plastic films, various coupled materials, aluminum, fabric, non woven, glass fiber, carbon fiber and similar materials, said tool change device comprising:
a tool holder (28) having a direct and quick compressed air feed; a tool or blade holder head (16); and a block (14) stabilized on a lower front surface thereof to said tool or blade holder head (16) and coupled on an upper front surface thereof by a coupling device to a lower front surface of said tool holder (28) for quick coupling/centering and extraction with translatory movement between said block (14) and said tool holder (28), wherein said coupling device includes a first appendix (34) extending vertically downwardly from a first end of said lower front surface of said tool holder (28) providing an abutment for said block (14) and having a horizontally directed through hole (38) for acceptance of a pin (50) adapted to be coupled to said block (14), and a second appendix (36) extending horizontally from a second end of said lower front surface of said tool holder (28) opposing said first end of said lower front surface of said tool holder (28) having a vertically directed through hole (40) for acceptance of a screw or pivot (56) adapted to be coupled to said block (14).
