Abstract
A double-twist twister mechanism includes a pair of assemblies which rotate about oblique intersecting axes, support a nonrotating spool carrier and have portions extending through each other. The assemblies are connected together for concurrent rotation by an external elastic member which is passable over the spool carrier into engagement with concentrically arranged fasteners on both assemblies.
Claims11
A twister mechanism, comprising,
- a first revolving assembly including a spindle rotatable about a spindle axis, a second revolving assembly including a sleeve located in spaced relation around said spindle, said second revolving assembly being supported for rotational movement about a second axis which is oblique with respect to the spindle axis, elastic means connecting said first and second assemblies together for concurrent rotation,
- a spool carrier, a bearing connecting said spool carrier to said first revolving assembly, and a bearing connecting said spool carrier to said second revolving assembly to prevent rotation of said spool carrier,
- said first revolving assembly having portions which extend radially through said second revolving assembly and are separated by indentations, said second revolving assembly having circumferentially spaced sectors with portions which extend into said indentations, a first set of circumferentially spaced fastening means on said first assembly at a location radially outside said sleeve, a second set of circumferentially spaced fastening means on said second assembly externally of said sleeve, said elastic means connecting said first set and said second sets of fastening means.
