    • PURPOSE:To provide a metallic wire for a doffer capable of spinning a web of high quality even in a high speed, high productive spinning especially of a manufacturing process for producing nonwoven cloth and free from winding of a web around the roller even in a roller doffing since a back angle surface is formed in a circular arc-shape and accordingly the length of the time in which the metallic wire works on the scraping roller is long. CONSTITUTION:This is a metallic wire for a doffer used in combination with a metallic wire for a cylinder in which an operating angle X is 75-85 deg. and the depth B of a tooth is 0.5-2.0mm. In that metallic wire, an operating angle X is 45-70 deg., the depth B of a tooth is 1.5-3.0mm, the upper part of the operating angle of the tooth is connected to a straight line via a mildly upward-protruding curve and the upper part of the back angle is connected to a straight line whose inclination angle is smaller than that of the operating angle via a mildly upward-protruding curve. The tooth of the metallic wire is strong and hardly getting damage and accordingly the metallic wire enables to keep excellent spinning for a long time.
