Abstract
A cutting and transferring apparatus configured to from a second sheet by cutting a continuous body of second sheets and to transfer the second sheet onto a continuous body of topsheet. The cutting and transferring apparatus includes a blade roll having a blade; a bed knife; and a transfer roll configured to transfer the second sheet onto the continuous body of topsheet. The transfer roll receives an edge portion of the continuous body before cutting. The blade and the bed knife cut the continuous body of the second sheets, in a state where the machine direction MD and a vertical direction coincide with each other.
Claims14
A method of cutting a first continuous body of first sheets for absorbent articles in a cross direction orthogonal to a machine direction along a flow of manufacturing processes of the absorbent articles, thereby forming the first sheet, and transferring the first sheet thus formed onto a second continuous body of second sheets for the absorbent articles, the method comprising:
- forming the first sheet by a blade and a bed knife pinching and cutting the first continuous body, the blade protruding from an outer peripheral surface of a blade roll disposed on one side of the first continuous body, the bed knife disposed on the other side of the first continuous body;
- and
- transferring the first sheet onto the second continuous body by a transfer mechanism disposed downstream of the blade roll and the bed knife in the machine direction,
- wherein
- the transfer mechanism at least receives an edge portion of the first continuous body on a downstream side in the machine direction before the first continuous body is cut,
- the blade and the bed knife cut the first continuous body guided between the blade and the bed knife, in a state where the machine direction and a vertical direction coincide with each other,
- a pressing portion of the blade roll presses the first continuous body against the bed knife, and
- the pressing portion presses the first sheet against the transfer mechanism after the first continuous body is cut.

- a blade roll configured to be disposed on one side of the first continuous body and having a blade protruding from an outer peripheral surface of the blade roll;
- a bed knife configured to be disposed on the other side of the first continuous body and fixed to face the blade roll with the first continuous body interposed therebetween;
- and
- a transfer mechanism disposed downstream of the blade roll and the bed knife in the machine direction, and configured to transfer the first sheet onto the second continuous body,
- wherein
- the blade is configured to cut the first continuous body by pinching the first continuous body with the bed knife to obtain the first sheet,
- the transfer mechanism is configured to at least receive an edge portion of the first continuous body on a downstream side in the machine direction before the first continuous body is cut,
- the blade and the bed knife are configured to cut the first continuous body guided between the blade and the bed knife, in a state where the machine direction and a vertical direction coincide with each other,
- the blade roll further has a pressing portion,
- the pressing portion is configured to press the first continuous body against the bed knife, and
- the pressing portion is configured to press the first sheet against the transfer mechanism after the first continuous body is cut.
