An assembly and method for installing sliders and end terminations onto a reclosable zipper for plastic bags is disclosed. The assembly includes a base with a cam path. A rotor is mounted on the base and includes at least one slider installing member and at least one end termination installing member. The rotor includes a cam follower extending into the cam path and secured to one of the slider installing member and end termination installing member which is reciprocally mounted on the rotor and is reciprocated by the interaction of the cam path and cam follower. At a first point in the rotation of the rotor the slider installing member and the termination installing member are supplied with sliders and terminations. At a second point in the rotation of the rotor the slider and terminations are simultaneously installed onto a zipper.
