A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.

A pleated filter preparation system is provided for accurately counting pleats along a continuous sheet of pleated filter material and cutting the sheet into filter strips to be formed into filters. The pleated filter preparation system includes a pleat driver having multiple drive gears that engage with the pleats of the pleated filter material to move the pleated filter material through the system. A pleat counter counts peaks and valleys of each pleat comprising the pleated filter material so as to identify a target pleat to be cut. The pleat counter clamps and stretches the target pleat to distinguish the target pleat among the other pleats. A punch cut station cuts the target pleat to form a filter strip having a desired number of pleats. A pleat compressor compresses the filter strips to a predetermined size and then ejects the filter strips into a suitable container or bin.

A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.
