Abstract
Two paths parallel paths feed a common path. A clamp removes separate articles in each parallel path. Each path positions articles on opposite sides of a surface, such as a conveyor. In a back and forth motion, another clamp sequentially clamps the articles of laundry from the opposite sides and places each article on the surface. Another clamp extends through the surface to sequentially clamp the articles on a trailing edge. The clamp moves the articles linearly off the surface and rotates the articles onto another surface, such as a lower surface. On the other surface, the article is conveyed to a pick-up position. A pair of clamps drag the article by an edge onto a stacked position. The stack is adjusted in height to position the stack for receiving the next article.
