BEAM FOR A DYEING APPARATUS

摘要

A beam for a dyeing apparatus comprises a pair of concentric inner and outer tubes, each having a multiplicity of peripheral holes therethrough. A net of a heat-and corrosion-resistant material is wound on the outer tube for supporting materials (to be treated) thereon to keep the materials from being marked with traces of the holes or any projections of the outer tube. The meshes of the net are smaller in size and larger in number per unit area than the outer tube's holes, which are in turn smaller in size and larger in number per unit area than the inner tube's holes, making the liquid flow uniform and hence suitable to penetrate uniformly throughout the materials.
