A manufacturing apparatus, for moving sliders for opening and closing mating zipper elements along the mating zipper elements, includes a roller and a projection. The roller rotates about an axis substantially perpendicular with a path of a film including the mating zipper elements and contacts the film as the film moves in the film path at a speed equal to the speed of rotation of the roller. The projection rotates about an axis at a speed different than the rotational speed of the roller, with the projection rotating into proximity to the moving film along predetermined lengths of the film so as to be contactable with sliders mounted thereon. The projection comes into contact with sliders positioned along the mating zipper elements of the predetermined lengths of film and pushes those sliders along the mating zipper elements to respective registered positions.
