Bungee cord arming notch fabricating method for underwater fishing weapon arrow, involves exerting two opposite transversal pressures on arrow, using two opposite punches, to create material outgrowth to be used as arming notch
Bungee cord arming notch fabricating method for underwater fishing weapon arrow, involves exerting two opposite transversal pressures on arrow, using two opposite punches, to create material outgrowth to be used as arming notch
The method involves exerting two opposite transversal pressures (P) on an underwater fishing weapon arrow (1), at the place of a notch to be realized, using two punches (3) acting in opposition. The two opposite transversal pressures are adapted to create a material outgrowth (2) to be used as an arming notch. A cavity is formed on the upstream side of the outgrowth in order house the link connecting bungee cords. A slope is formed at the downstream side of the outgrowth. An independent claim is also included for a device for implementing a bungee cord arming notch fabricating method.
