A self-adjusting stripper pin is for use in a strap chute for a strapping machine and includes a mount mounted to a fixed portion of the strapping machine, a reciprocating pin disposed in the mount for reciprocating movement relative to the mount and a pin spring disposed between the pin and the mount for biasedly mounting the pin to the mount. When the movable wall of the strapping machine is moved toward the fixed wall of the strapping machine, the pin moves out from the track to allow the strap to traverse therethrough and when the movable wall is moved away from the fixed wall, the pin is moved into the track to urge the strap out of the track. The spring positions the pin at about an outer edge of the track when the movable wall is moved away from the fixed wall.
