A folding machine for folding fiber products, comprising:
- a first folding device comprising:
- a first cutting device for cutting a first fiber product;
- a first delivery wheel, the first delivery wheel receiving the cut first fiber product from the first cutting device;
- a first folding-line wheel adjacent to the first delivery wheel, wherein the first folding-line wheel and the first delivery wheel make a first folding line on the first fiber product;
- a first platen wheel adjacent to the first delivery wheel and downstream of the first folding-line wheel, wherein the first platen wheel and the first delivery wheel fold the first fiber product along the first folding line;
- and
- a first folding wheel adjacent to the first delivery wheel, the first folding wheel receiving the first fiber product from the first delivery wheel;
- and
- a second folding device comprising:
- a second cutting device for cutting a second fiber product;
- a second delivery wheel, the second delivery wheel receiving the cut second fiber product from the second cutting device;
- a second folding-line wheel adjacent to the second delivery wheel, wherein the second folding-line wheel and the second delivery wheel make a first folding line on the second fiber product;
- a second platen wheel adjacent to the second delivery wheel and downstream of the second folding-line wheel, wherein the second platen wheel and the second delivery wheel fold the second fiber product along the first folding line;
- and
- a second folding wheel adjacent to the second delivery wheel, the second folding wheel receiving the second fiber product from the second delivery wheel, wherein the first folding wheel and the second folding wheel are adjacent and make a second folding line on the first fiber product and the second fiber product passing therethrough and fold the first fiber product and the second fiber product along the second folding line,
- wherein each of the first delivery wheel and the second delivery wheel includes at least one indentation and at least one adhesive hole, each of the first folding-line wheel and the second-folding line wheel includes at least one protrusion and at last one adhesive hole, and the protrusions of the first folding-line wheel and the second folding-line wheel conform, respectively, to the indentations of the first delivery wheel and the second delivery wheel to make the first folding lines, respectively, on the first fiber product carried by the first delivery wheel and on the second fiber product carried by the second delivery wheel, and
- wherein each of the first folding wheel and the second folding wheel includes at least one protrusion and at least one indentation, and the protrusion and the indentation of the first folding wheel conform respectively to the indentation and the protrusion of the second folding wheel to make the second folding line on the first fiber product and the second fiber product.
