Method and means for clearing yarn underwindings from textile spindle assemblies

A method of clearing yarn underwindings from rotating spindle assemblies spaced along the length of an elongate textile machine, comprising:

• providing, at fixed longitudinally-spaced locations upon the textile machine and in association with respective ones of the rotating spindle assemblies, a plurality of independently-actuable underwinding clearers each adapted when actuated to effect clearance of the yarn underwindings from an associated one of the spindle assemblies;
• traversing the length direction of the textile machine by a mobile apparatus movable, while traversing the textile machine, into and out of proximity with successive ones of the underwinding clearers;
• and actuating the clearers sequentially during movement of the mobile apparatus into proximity with successive ones of them.

A method of clearing yarn underwindings from longitudinally-spaced spindle assemblies of an elongate textile machine, comprising:

• providing independently-actuable clearers in association with respective ones of the spindle assemblies of the textile machine, said clearers being disposed at fixed longitudinally-spaced locations along the length of the textile machine and each of the clearers being adapted upon actuation thereof to effect clearance of yarn underwindings from an associated one of the spindle assemblies;
• and actuating the clearers sequentially by moving clearer-actuating means in the length direction of the textile machine and into clearer-actuating proximity with successive longitudinally-spaced ones of the clearers.

In combination with an elongate textile machine including along its length a plurality of rotating spindle assemblies having yarn underwindings thereon, the improvement comprising:

• clearer means for when actuated clearing the yarn underwindings from the rotating spindle assemblies;
• said clearer means including a plurality of independently-actuable clearer units carried by said textile machine, at fixed locations along the length thereof, adjacent respective ones of said spindle assemblies;
• and actuating means movable relative to said clearer units along the length direction of said textile machine and into actuating-proximity with successive ones of said clearer units for sequentially actuating said clearer units.

A method of clearing rotating spindle assemblies spaced along the length of an elongate textile machine of yarn underwindings formed upon a lower portion of each of the spindle assemblies and connected by a length of yarn to a yarn package undergoing formation upon an upper portion of each of the spindle assemblies, comprising:

• providing, upon the textile machine and in association with respective ones of said spindle assemblies, a plurality of underwinding clearers independently actuable by the impingement of air blasts thereon and each adapted when actuated to effect separation of the length of yarn innerconnecting the yarn underwindings and the yarn package upon the associated one of said spindle assemblies;
• and actuating the clearers in sequential relationship to each other by impinging blasts of air sequentially upon successive ones of the clearers.

• providing, at longitudinally-spaced fixed locations upon the textile machine adjacent respective ones of said spindle assemblies, a plurality of independently-actuable underwinding clearers each adapted when actuated to effect separation of the length of yarn innerconnecting the yarn underwindings and the yarn package upon the adjacent one of said spindle assemblies;
• traversing the length direction of the textile machine by a mobile apparatus having clearer actuating means movable therewith;
• and actuating the clearers, in sequential relationship to each other, when the mobile apparatus moves into proximity with successive ones of them.

• providing, upon the textile machine and in association with respective ones of said spindle assemblies, a plurality of underwinding clearers actuable independently of each other by the impingement of blasts of air thereon and each adapted when actuated to effect separation of the length of yarn innerconnecting the yarn underwindings and the yarn package upon the associated one of said spindle assemblies;
• traversing the length direction of the textile machine by a mobile apparatus having air-blast producing means movable therewith for actuating the clearers;
• and actuating the clearers, in sequential relationship to each other and by the impingement thereon of blasts of air from the air-blast producing means, when the mobile apparatus moves into proximity with successive ones of the clearers.

A method of clearing yarn underwindings from rotating spindle assemblies spaced along the length of an elongate textile machine, comprising:

• providing, upon the textile machine and in association with respective ones of the rotating spindle assemblies, a plurality of underwinding clearers actuable pneumatically and independently of each other by the impingement of blasts of air thereon and each adapted when actuated to effect clearance of the yarn underwindings from an associated one of the spindle assemblies;
• traversing the length direction of the textile machine by a mobile apparatus;
• and actuating the clearers sequentially, during movement of the mobile apparatus into proximity with successive ones of them, by subjecting the clearers to actuating blasts of air emanating from the mobile apparatus.
