ABSTRACT:
An improved method and apparatus for treating strand-like material is described. The method comprises conveying loops of such strand-like material supported by conveyor means through a heating zone wherein provision is made for causing certain portions of said loop material to experience substantial peripheral sliding movement in their contact with and with respect to said conveyor means, which movement has been found to reduce irregularities in the subsequent dyeing of the strand-like material.
