The present invention relates to thread storage and dispensing systems which protect the thread from damage. A spool system of the present invention includes a thread spool around which thread is wound. A spool cap is mounted to the thread spool in a manner which substantially encloses the thread. The spool cap may include an opening through which the thread is extended as it is fed into a sewing machine. The spool cap may be selectively and removably mounted to the thread spool in any of a variety of manners. For instance, detents may be provided on the cap to engage a corresponding groove in the thread spool. Optionally, a stopper is provided which may be inserted into the opening through which the thread is fed into a sewing machine. The stopper may frictionally engage the cap and thread, and secure the thread to prevent it from unraveling.
La présente invention concerne des systèmes de stockage et de distribution de fil qui protègent le fil contre un endommagement. Un système de bobine selon la présente invention comprend une bobine de fil autour de laquelle le fil est enroulé. Un chapeau de bobine est monté sur la bobine de sorte à envelopper sensiblement le fil. Le chapeau peut comporter une ouverture à travers laquelle le fil est déroulé lorsqu~il alimente une machine à coudre. Le chapeau peut se monter de manière sélective et amovible sur la bobine sous diverses formes. Par exemple, le chapeau peut présenter des crans s~engageant avec une rainure correspondante de la bobine. Facultativement, un butoir est insérable dans l~ouverture à travers laquelle le fil alimente une machine à coudre. Le butoir peut entrer en contact par friction avec le chapeau et le fil, et retenir le fil pour éviter son effilochage.
