Abstract (en)

A yarn splicer device (4) comprising a pair of opposite plates (8,12) which are rotatable with respect to a common drive axis (X-X), the plates (8,12) being spaced apart from each other, along said drive axis (X-X), so as to identify a passage path (14) of a first yarn (16) ending with a first thread (20) and a second yarn (24) ending with a second thread (28), to be mutually spliced, tail tearing means (32), configured to grasp and tear tails (36) of said first and second thread (20,28), so as to obtain tearing points (40) positioned at least partially inside said passage path (14) of the first and second yarn (16,24), wherein said tail tearing means (32) comprise a first pair of counter-rotating rotatable cylinders (44), configured to clamp the tail (36) of said first thread (20) and/or a second pair of counter-rotating rotatable cylinders (48), configured to clamp the tail (36) of said second thread (28).
