PERFECTED ANGLE STAPLING MACHINE

The present invention relates to a corner stapling machine comprising， - at least one stapling head (Tg) intended for stapling at right angles elements of an object such as a crate， - a crimping arm (Br ) corresponding and whose free end is provided with a crimping tool， said crimping arm being movable between a release position where said tool is arranged outside the crate and a working position where said tool moves opposite the clip (Ag) placed to fold the two lateral strands (Bc1， Bc2) protruding from the clip， characterized in that the crimping tool (Os) is provided with two lugs (Gtl， Gt2) hingedly mounted on a pusher (Pr) movable between a retracted position of rest and a position of advancement， the pusher (Pr) being coupled to an actuator (Vh)， and in that， during the movement of advancement of the pusher (Pr) under the effect of the operation of the actuator (Vh)， the two pins (Gtl， Gt2) are moved to fold and crimp the two lateral strands (Bc1， Bc2) projecting from the clip. The crimping of the clip is carried out ideally and reproducibly. The operational reliability of the stapling machine is greatly improved.
