An apparatus for dispensing plastic fasteners having a cross bar at the end of a filament from fastener stock. The apparatus includes a gun shaped casing made of plastic. A hollow needle having an inlet opening and an outlet opening is mounted on the casing. A guide groove is formed on the casing for receiving the fastener stock, the guide groove being in communication with the inlet opening in the hollow needle and being at an angle with the hollow needle. The apparatus also includes an ejector rod for pushing the cross bar of a fastener fed into the hollow needle out through the outlet opening of the needle. The guide groove in the casing includes a front wall that is bevelled. The front wall includes a bottom edge which is bevelled. The corner formed by the front wall of the groove and a sidewall of the casing is also bevelled. The three bevels minimize the likelihood that the cross bar of the fastener will jam as it passes from the guide groove into the hollow needle. |
