Abstract
A folding apparatus for laundry items such as sheets or the like employs a feed conveyor of continuous tapes or ribbons arranged at an incline. The leading edge of the fed sheet drops by gravity from the upper conveyor end. A blast from an adjacent air bar forces the longitudinal mid-point of the sheet to move onto a second conveyor substantially parallel to the feed conveyor and proceed toward the initial feed station whereat the once-folded sheet drops in front of a second air bar which forces the mid-point of such sheet onto a lower, third conveyor leading away from the feed station. The twice-folded sheet is then driven into the bite of pinch rolls disposed beneath the third conveyor and is folded twice more by buckle folders in the course of proceeding to a stacking means of simplified design. The air bars instrumental in effecting the first two folds are actuated by measuring means employed in combination with sheet-sensing means as will hereinafter be explained in greater detail.
