Sheet Processing

A sheet processing (flat paper processing) machine uses blades to cut roll or sheet paper, nonwoven fabric, adhesive tape, film, etc. according to the desired dimensions (sheet). Various sheet processing methods are used according to the characteristics of materials, finish dimensions, etc.

  • Cutting Machine

    This machine cuts sheet paper, nonwoven fabric, adhesive tape, film, etc. to any dimensions.
    It can cut anything from a few to a 1000 sheets in a single cut. Because the blade is fixed in a single position, work is conducted while moving the cutting side of the target material in the direction of the blade. Frequently, such machines have air blown from under the table to help the materials being cut move more smoothly.
    The dimensions are adjusted through moving the back gauge forwards and backwards.
    Since the cutting machine cannot handle rolls, it is only used with sheet materials.

  • Drum Cutter

    This machine is used to make sheets (Flat paper) by cutting roll paper, non-woven fabric, adhesive tapes, films etc. after winding them multiple times into a drum shape. It is also commonly known as Taiko.
    The number of windings varies depending on the characteristics and thickness of the material to be cut. The feature of this machine is that even though it instantly processes rolls into sheets (Flat paper), measurement error occurs in the flow dimension between the first winding and the last winding.
    As the drum cutter (Taiko) is mainly used for cutting sheets into big chunks with rough measurement, precise measurement cannot be expected. To overcome this, the drum cutter (Taiko) is usually paired with the cutting machine which enables roughly cut drum cutter (Taiko) sheets to be precisely adjusted by the adjacent cutting machine.
    The cutting of wrapping paper etc. where rough measurement is allowed upon its usage can be processed by using only the drum cutter (Taiko) without using the cutting machine.

  • Cutter

    This machine uses a rotary cutter (flow) and slit blades (width) to cut roll paper, nonwoven fabric, adhesive tape, film, etc. according to the desired dimensions (sheet). Because multiple rolls can be worked, the feature of this machine is that extremely good work efficiency can be realized by adding more rolls.
    The multiple rolls of materials are cut together while being fed through the pass line (roller), and layers of cut sheet (flat paper) are accumulated as they pass over the belt.
    If only processing one or two rolls of paper that has little thickness or texture, the materials may not flow out along the belt following cutting by the rotary cutter; hence a certain number of rolls are required. If the materials being cut comprise only a few rolls of paper having little thickness or texture, they are often processed by means of drum cutter and cutting machine.

  • Sheet Cutter

    This machine uses a rotary cutter (flow) and slit blades (width) to cut roll paper, nonwoven fabric, adhesive tape, film, etc. according to the desired dimensions (sheet). This has structure similar to the cutter, however, usually only one roll can be worked and the machine itself is smaller in size.
    Where the drum cutter and cutting machine can perform cutting on multiple rolls or sheets, the sheet cutter can only cut one sheet at a time and thus has a slower processing speed. However, it is more appropriate for use when it is necessary to conduct inspection while cutting or in cases where the materials are susceptible to damage.
