The arm of the further double arm lever and the arm of the one double arm lever are in alignment rectilinearly in the center-shed position and are together equal in length to the length of a first arm of the still further double arm lever, so that these two arms, the connecting rod and a connecting line extending between the fixedly arranged pivot axles for the further double arm lever and the still further double arm lever form a parallelogram.

Abstract: An apparatus for spreading laundry flatwork pieces, such as bed sheets, before feeding them to subsequent processing equipment, such as an ironer and a folder. The flatwork pieces are spread apart by pairs of clamps, there normally being one pair of clamps at the left end, another pair of clamps at the right end, and a third pair of clamps at the center of the apparatus. The spread-out flatwork pieces are blown onto a conveyor for conveying them to the subsequent processing apparatus. Trailing edge sensors are positioned at different levels below the clamps to sense the upward passage of the bottom edge of the laundry flat piece deposited on the conveyor, and a selector switch enables one of the sensors and disables the other, depending upon the speed at which the conveyor is being operated. Proximity switches sense the positions of the clamps. There is an overlying conveyor cooperating with the main conveyor for sandwiching the laundry flat piece as it is moved into the apparatus for stretching purposes.
