Abstract (en)
[origin: WO2011039696A1] The invention relates to a hollow punch for processing leathers and a blocking system of the punch to a shaft. The punch (21) is insertable in a seating (31) of a shaft of a leather-processing machine, a projecting blocking element (23) being fixed at an internal side wall (38) of the seating (31). The hollow punch (21) comprises: a shank (22); a portion (44) of an end of the shank (22) being conformed such as to engage a projecting portion of the blocking element (23) such that the shank (22) can move along the seating (31); and a recess (25), obtained in a side wall of the shank (22) such as to be joint-coupled to the blocking element (23), when the portion (44) of the end of the shank (22) is engaged with the blocking element (23), by means of a rotation of the hollow punch (21) in a predetermined rotation direction (W), with a consequent axial blocking of the hollow punch (21) with respect to the seating (31).
