A feed roller rotated by a drive mechanism is provided on the other side of the movement path of the presser roller or the backing plate, and a tip is placed at an appropriate interval on the long towel fabric feeding side of the cutting blade. When the tip is in contact with the plain weave part of the long towel fabric, the plain weave part is allowed to pass through, and when the tip part is in contact with the boundary between the plain weave part and the pile weave part of the long towel fabric, it engages with the pile fabric and passes through it. A positioning piece having a receiving portion shaped to prevent passage is disposed along the movement locus, and the feed roller also moves the long towel fabric from the positioning piece in the direction of the cutting blade, and the long towel fabric is transferred to the positioning piece. In the long towel fabric cutting device, the cutting blade cuts the plain weave portion in a state in which the movement of the long towel fabric is stopped when the boundary portion of the pile weave portion hits, and the feed roller is driven. It consists of a rotating shaft connected to the source and a rotating ring fitted concentrically around the rotating shaft, and the rotating ring is divided into a plurality of rotating ring elements at a distance in the axial direction. The rotating wheel elements are configured to be rotatable individually, and between each rotating wheel element and the rotating shaft, a plain weave portion of the corresponding width of the long towel fabric that is in contact with each of the rotating elements is provided as a positioning piece. When in contact with the receiving part of the positioning piece, the rotary wheel element can be rotated by the rotating shaft and rotational force, but the boundary part of the pile weave in the corresponding width part abuts and engages with the receiving part of the positioning piece. The present invention attempts to provide a long towel fabric cutting device in which a slip means is interposed such that the rotary wheel element cannot be rotated by rotational force, and the center position of the plain weave portion of the long towel fabric is provided.
