A sleeving apparatus is used to place sleeves about looped belts. A bel t 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 sleev e 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.
