Abstract

256,035. Marshall & Co., Ltd., T. J., and Wedgwood, R. E. July 11, 1925. Dandy rolls.-The tendency to bend and sag of dandy rolls of great length and large diameter used in fast running paper machines is overcome by the provision of an interior concentric wire work cylinder comprising a spiral h and longitudinal wires i, the two cylinders being separated by distance pieces or rings f formed with holes l to lighten them. The whole is soldered together. The wires i are made of strip or bar metal of greater width than thickness with the width extending radially of the roll, and may be of zigzag or sinuous form. The spiral h also is of sinuous or zig-zag form, the consecutive turns being connected together as at h<1>, Fig. 2.
