A fiber product folding apparatus, comprising:
- a first dashed-line cutting device including a first dashed-line cutter and a first dashed-line roller arranged adjacent to the first dashed-line cutter, wherein a first fiber product moves in a first conveying direction to pass between the first dashed-line cutter and the first dashed-line roller, and the first dashed-line cutter is operable with respect to the first dashed-line roller to form a plurality of first dashed lines on the first fiber product across a width direction of the first fiber product, wherein adjacent first dashed lines are spaced from each other by an interval along the first conveying direction, and the interval between the adjacent first dashed lines is adjustable by controlling a rotational speed of the first dashed-line roller with respect to the first dashed-line cutter;
- a first severing device including a first severing cutter, a first severing roller adjacent to the first severing cutter, and a first intermediate roller adjacent to the first severing roller, wherein the first severing roller receives the first fiber product that is formed with the first dashed lines, and when a length of the received first fiber product does not reach a predetermined length, the first severing cutter is kept inactive, and the first fiber product is forwarded to the first intermediate roller;
- a first folding roller adjacent to the first intermediate roller and arranged to receive the first fiber product via the first intermediate roller;
- a second dashed-line cutting device including a second dashed-line cutter and a second dashed-line roller arranged adjacent to the second dashed-line cutter, wherein a second fiber product moves in a second conveying direction to pass between the second dashed-line cutter and the second dashed-line roller, and the second dashed-line cutter is operable with respect to the second dashed-line roller to form a plurality of second dashed lines on the second fiber product across the width direction of the second fiber product, wherein adjacent second dashed lines are spaced from each other by an interval along the second conveying direction, and the interval between the adjacent second dashed lines is adjustable by controlling a rotational speed of the second dashed-line roller with respect to the second dashed-line cutter;
- a second severing device including a second severing cutter, a second severing roller adjacent to the second severing cutter, and a second intermediate roller adjacent to the second severing roller, wherein the second severing roller receives the second fiber product that is formed with the second dashed lines, and when a length of the received second fiber product does not reach a predetermined length, the second severing cutter is kept inactive, and the second fiber product is forwarded to the second intermediate roller;
- and
- a second folding roller adjacent to the second intermediate roller and arranged to receive the second fiber product via the second intermediate roller;
- wherein the first folding roller and the second folding roller are arranged adjacent to each other and are operable to perform folding of the first fiber product and the second fiber product that pass between the first folding roller and the second folding roller at a fold length.
