Abstract
A method and apparatus for forming a yarn reserve to feed picks to a loom in which a given length of filling yarn is accumulated in a storage chamber, and the filling yarn is retrieved and introduced into a shed by propelling means implemented by a single guidance conduit. The propelling means also acts as a tensioning element for the yarn when it is propelled.
Claims25
A device for forming a yarn reserve to feed picks to a loom, comprising:
- (a) a storage chamber being located between a yarn supply source and a machine for inserting picks into a loom, said storage chamber having an upper part and a perforated lower part, said upper part and said lower part being machined and joined to form a divergent clearance at a first end of said chamber and said upper part and said lower part being machined and joined to form a cavity therebetween;
- (b) means for introducing yarn into said storage chamber comprising a compressed-fluid nozzle, said nozzle directing fluid into said storage chamber, said fluid passing through said perforations of said lower part of said storage chamber generating an internal turbulence therein to arrange yarn in juxtaposed substantially regular loops;
- and
- (c) means for retrieving yarn from said storage chamber, said means for introducing yarn into said storage chamber tensioning the yarn upon retrieval.

A device for forming a yarn reserve to feed picks to a loom, comprising:
- (a) a storage chamber being located between a yarn supply source and a machine for inserting picks into a loom;
- (b) means for introducing yarn at a first end of said storage chamber;
- and
- (c) means for retrieving yarn from said storage chamber, said means for introducing said yarn into said storage chamber tensioning the yarn upon retrieval;
- wherein a solid part rotationally driven by a shaft is located at a second end of said storage chamber, said solid part sealing said second end during yarn introduction and said solid part opening said second end when said storage chamber is empty.
