Textile spindle assembly and method

In a textile spinning machine or the like including a spindle assembly rotatable about a generally vertical axis and having a blade member about which packages of strand material are adapted to be formed, and having a spool-like member underlying said blade member and adapted to receive coils of strand material preparatory to doffing of each one of said strand packages;

• said machine including means for freeing said coils for clearance from said spool-like member during formation of the next ensuing one of said packages;
• the improvement comprising:
• strand guiding means associated and rotatable with said assembly for preventing overlapping of the strand material of said coils upon itself during formation of said coils upon said spool-like member.

In a textile machine including a rotatable spindle assembly for forming successive packages of textile strand material;

• said assembly having a first member about which each one of said packages is formed, and having a second member upon which coils of strand material are wound following formation and preparatory to doffing of said each one of said packages;
• said machine including means for freeing said coils for clearance from said second member during formation of the next ensuing one of said packages, the improvement comprising:
• said second member having groove means upon the outer surface thereof for receiving successive increments of the coil forming strand material and for causing the same to follow, during formation of said coils, a nonoverlapping and generally helical path away from said first member.

In a textile machine including a rotatable spindle assembly of the type used in the formation of successive packages of textile strand material, said assembly including a spool-like member upon which coils of the strand material are wound preparatory to doffing of each yarn package;

• said machine including means for freeing said coils for clearance from said member during the next ensuing package-building operation of said assembly, the improvement comprising:
• said spool-like member having helical groove means associated therewith for preventing overlapping of said coils upon each other during the winding thereof upon said member, and for axially positioning strand material upon said member at a predetermined location facilitating clearance thereof from said member.

In the method of winding strand material extending from a source to a rotatable textile spindle assembly having a first member upon which strand packages are adapted to be successively formed, and a second member spaced along the length of the assembly from the first-mentioned member;

• said method including the steps of (a) winding strand material upon the first member to form each strand package, (b) winding strand material upon the spool member preparatory to doffing each completed strand package from the assembly so as to form thereon a plurality of coils of strand material effective to maintain strand connection between the assembly and the strand source upon doffing of the formed package from the assembly, and (c) freeing the coils for clearance from the spool member during formation of the next ensuing strand package;
• the improvement comprising:
• completing step (b) without overlapping the coil forming strand material upon itself.
