US Patent No. 1,641,588, granted Sept. 6, 1927 to Martin Hölken Jr. of Barmen, Germany, for a method and apparatus for stretch-spinning artificial silk (cuprammonium rayon). Each spinneret is fed by its own rotary gear pump instead of directly from a common pressurized supply pipe, so that thread fineness stays uniform across all spinning heads. The text describes the apparatus, with two sheets of drawings, the operation, and seven claims covering the method and the pump, pivot and articulated-arm assemblies.
