In order to provide a clothing manufacturing apparatus capable of improving production efficiency, a clothing manufacturing apparatus includes a cylindrical member having openings at both ends; and reversing means configured to reverse lower body clothing inside out by passing the lower body clothing in a state in which the cylindrical member is inserted through a waist opening of the lower body clothing and a crotch portion of the lower body clothing covers one of the openings of the cylindrical member through inside of the cylindrical member from the crotch portion.

An apparatus and method for inverting a flexible foam sheet being conveyed on a moving conveyer grips the leading edge of the foam sheet with a clamp and raises the clamp above the moving conveyor surface. As the leading edge is held by the clamp, the foam sheet progressively separates from the moving conveyor surface and is curled back over itself until the trailing edge of the foam sheet passes beyond the clamp and the foam sheet is inverted. Upon releasing the clamp, the inverted foam sheet is deposited onto the moving conveyor, now with the former leading edge comprising the trailing edge. In an embodiment, the foam sheet comprises two profiled layers nested together, and the clamp lifts the leading edge of the top profiled layer to separate and invert such top layer from the bottom layer, depositing the inverted top layer onto the conveyor behind the bottom layer.
