Abstract
A triple folding device for folding a hem of a towel utilizes four cams respectively driven by a single rotative drive source, and four link mechanisms respectively driven by corresponding cams. A guide ruler secured to a first guide shaft is driven by one of the link mechanisms. A thrust block is connected to and driven by another one of the link mechanisms. An upper presser is secured to a second guide shaft which is driven by yet another link mechanism. Another second thrust block is connected to and driven by yet another link mechanism. A lower presser is positioned under the upper presser. A pressing unit is driven by a second drive unit. A guide ruler is moved vertically and horizontally by the vertical motion of the first guide shaft and the horizontal motion of the first thrust block for guiding a hem of a towel. The lower presser is moved horizontally by a first drive unit to press the hem of the towel. The upper pressure is moved vertically and horizontally by the vertical motion of the second guide shaft and the horizontal motion of the second thrust block for folding the hem of the towel positioned between the lower presser and a working table. The lower presser is moved horizontally by a first drive unit to press the hem of the towel.
