Improvements to a device for joining textile yarns and corresponding device

Abstract

A device for joining two ends of two textile yarns by means of decomposition and subsequent re-composition of the twists of said ends to make up a single yarn including two components disposed opposite each other so as to make two respective joining elements face each other, between which the two ends of the two textile yarns to be joined are interposed.

1 . Component of a device for joining two ends of two textile yarns by means of decomposition and subsequent re-composition of the twists of said ends to make up a single yarn, said component comprising:
 a frame having a housing seating;   at least one support plate housed in said housing seating;   spring means located between the frame and the support plate;   at least one joining element having a shape mating with the housing seating and disposed above the support plate;   wherein said joining element and said support plate are selectively connected to each other by means of connection means of the magnetic type.   
     
     
         2 . Component as in  claim 1 , wherein it comprises reciprocal positioning means between the support plane and the joining element, said reciprocal positioning means being configured to guarantee the correct positioning of said joining element on said support plane. 
     
     
         3 . Component as in  claim 1 , wherein said connection means comprise at least one magnet and at least one respective ferromagnetic element both disposed mating on said joining element and on said support plate to connect them together by magnetic attraction. 
     
     
         4 . Component as in  claim 3 , wherein said at least one magnet is provided on said support plate and said at least one ferromagnetic element is provided on said joining element. 
     
     
         5 . Component as in  claim 3 , wherein said at least one ferromagnetic element is substantially planar defining a base made of ferromagnetic material associated with said joining element and extending over substantially the whole surface of the latter facing toward the support plate. 
     
     
         6 . Component as in  claim 3 , wherein it comprises one or more of said magnets integral with the support plate and distributed on said support plate in a manner coordinated with said ferromagnetic element. 
     
     
         7 . Component as in  claim 1 , wherein it comprises:
 an internal circular support plate connected, by means of first connection means of the magnetic type, to a mating circular joining element;   an external annular support plate connected, by means of second connection means, to a mating external annular joining element;   said external support plate being concentric to said internal support plate and selectively mobile with respect to said internal support plate.   
     
     
         8 . Component as in  claim 1 , wherein it comprises an RFID recognition system provided with at least one electronic label applied at least on said joining element and/or on said housing seating, and at least one data reader cooperating with said electronic label. 
     
     
         9 . Joining element for a component of a device for joining textile yarns comprising at least one ferromagnetic element disposed substantially planar and an external layer overlapping and integral with said ferromagnetic element. 
     
     
         10 . Spare kit provided with at least a plurality of joining elements that differ from each other in materials and/or sizes, and with a plurality of support plates mating with said respective joining elements, said joining elements and said respective support plates having respective connection means of the magnetic type and being interchangeable in the housing seating of the frame of a component as in  claim 1 . 
     
     
         11 . Device for joining two ends of two textile yarns by means of decomposition and subsequent re-composition of the twists of said ends to make up a single yarn, said device comprising two components as in  claim 1 , disposed opposite each other so as to make the two respective joining elements face each other, said components being able to be selectively moved toward and away from each other along a work axis, perpendicular to both joining elements, and being rotatable with respect to each other and with respect to said work axis. 
     
     
         12 . Method for replacing a joining element in a component of a joining device as in  claim 1 , wherein said method comprises:
 exerting a pressure on the joining element to be replaced, with respect to the support plate, to overcome the magnetic attraction force in order to separate said joining element from said support plate;   removing the joining element to be replaced;   positioning a new joining element on the support plate in order to establish a new and correct magnetic connection between said joining element and said support plate.
