The present invention relates to a half-knife treatment device used in a device for manufacturing a dressing band for protecting an affected part attached to an affected part for protection of skin wounds, etc., while improving productivity in manufacturing a large amount of dressing band for protecting an affected part within a short time, It relates to a half-knife treatment device for manufacturing a portable dressing band for protecting the affected area, which intends to reduce the half-cutting defects of the dressing material, wherein the fabric (P) on which the dressing material 20 is applied is applied to the release paper film fabric 10 on which the break line is formed. A portable wound protection dressing band manufacturing device in which a plurality of dressing materials are attached on a release paper film that receives fabric (P) from the supplied fabric supply device and manufactures a portable wound protection dressing band (1) with a plurality of dressing materials attached In, by receiving the fabric (P) to which the dressing material is applied from the fabric supply means 100, the dressing material is pressed by the dressing material pressing means 200, and the dressing material transferred by the fabric transfer means 250 is applied. In the half-knife treatment device 300 for manufacturing a portable affected area protective dressing band, which half-cuts only the dressing material from the fabric (P), the half-knife processing device 300 for manufacturing the portable affected area protective dressing band includes a servo motor 311 ), the fabric (P) to which the dressing material is applied is half-cut by a press operated up and down by a), and the press includes an upper plate 310, a middle plate 320, and a lower plate 330 on the elevating shaft 312. It is supported by, and on the upper plate 310 of the press, a servo motor 311 for controlling the upper and lower operation of the middle plate 320 is installed, and an elevating shaft between
