Textile machine for spinning a yarn with an elastic or non-elastic core and a method for spinning a yarn with an elastic or non-elastic core

Abstract

A textile machine (4) for spinning a yarn (10) with a core (20), elastic or non-elastic, comprising stretching means (24), comprising at least two pairs of stretching rollers (28), cylindrical and rotating around stretching axes (X-X) parallel to each other, the stretching means (24) being configured to make the fibres parallel therebetween, of at least one ribbon of fibres (12,16) fed to said stretching means (24), along a feeding path (P) in which said at least one ribbon of fibres (12,16) converges straddling a centreline plane (M-M), an air spinning unit (8), arranged downstream of the stretching means (24), comprising a spinning chamber (9) configured to obtain yarn (10) by winding or twisting the fibres made parallel by said stretching means (24), a core feeding assembly (36), arranged upstream of the last pair of stretching rollers (28), configured to introduce said core (20) inside said at least one ribbon of fibres (12,16) before said at least one ribbon of fibres (12,16) enters inside the air spinning chamber (9) and is wound around said core (20). Said core feeding assembly (36) is configured so as to insert said core (20) along a tangential direction (T-T), tangent with respect to an outer side wall (44) of a stretching roller of said at least one pair of stretching rollers (28), and incident with said feeding path (P), inside said at least one ribbon of fibres (12,16), at the centreline plane (M-M), and upstream of the air spinning chamber (9).
