A sleeving apparatus is used to place sleeves about looped belts. A belt manipulation apparatus receives a resilient belt to be sleeved in an undeformed condition. As the belt advances through the belt manipulation apparatus, it is squeezed to form a protruding bight, in the form of a tongue, that is of a size to slide into a rectangular opening or passage defined by the four walls of a sleeve. A sleeve holder located adjacent to the belt manipulation apparatus maintains a sleeve in position to receive the belt to be sleeved. The belt manipulation apparatus urges or feeds the tongue forward into, and through the passage defined by the sleeve. As the tongue extends beyond the exit of the sleeve, it seeks to resume its undeformed shape and consequently, it forms a bulge or loop of increasingly large dimensions. When the belt is released from the belt manipulation apparatus and permitted to assume its position of lowest energy storage, a loop will have been formed at both ends of the belt and the mid-portion or waist of the belt will be constrained by the margins of the sleeve.
