ABSTRACT:
A laundry folder for folding small pieces, having means for automatically centering the pieces transversely relative to a longitudinal center line and maintaining them so centered in their travel through the folder, including photo-electric cells for spotting the pieces and centering them, the centering means including transversely shiftable belt means and the photo-electric cells controlling the means for shifting the belt means; means for compensating for stretchability of laundry pieces such as knit shorts, so as to fold them in true straight line formation despite deformation as would otherwise be caused by the stretchability of the pieces; a wicket for placing the folded pieces on a supporting surface and means for lowering the supporting surface as the pieces are placed thereon in a stack, so that as the stack is formed, the top piece of the stack is always at substantially the same height.
