Rotierende Schneidvorrichtung zur Herstellung von Streckmetall und entsprechendes Verfahren

摘要

In a process for forming expanded metal mesh by passing a deformable strip (S) between upper and lower discs having intermeshing teeth (232) where each tooth (232) has linear leading and trailing surfaces joined at an apex to define a nose angle (C) and each leading and trailing surface intersecting respective tangents to the disc to define entry (A) and exit (B) angles, respectively, (B) is selected in accordance with a mathematical relationship (I) between the radius of the tooth root (R), the tooth depth (D) and the strip thickness (T). Also claimed is such a method in which the entry angle (A) is selected in accordance with the same relationship.
