This invention discloses a counting production counting device, specifically a disposable plastic car seat cover counting and folding device. It discloses a two-sided folding component, used to fold the two sides of the material strip towards the center line. The two-sided folding component consists of a first guide plate and a first guide rod. The first guide plate is divided into a transition zone and a folding zone through which the material strip passes.
