Abstract
Die vorliegende Erfindung betrifft eine Ringspinnmaschine (1) und ein Verfahren zur Herstellung eines Core-Garns (11), wobei eine Klemmeinrichtung (6) mit in einer Klemmlinie (7) einander kontaktierenden Klemmrollen (8, 9) von einem ein Streckwerk (5) verlassenden Faserverband (2) und zumindest einem dem Faserverband (2) zuzuführenden Faden (4), insbesondere Endlosfilament durchlaufen wird, und wobei die Klemmlinie (7) durch zumindest eine an der Umfangsfläche (12) zumindest einer der Klemmrollen (8, 9) umlaufende Nut (13) unterbrochen ist, welche den zumindest einen Faden (4) beim Durchlaufen der Klemmeinrichtung (6) aufnimmt und an der Klemmlinie (7) vorbeiführt, ohne dass dieser von den einander kontaktierenden Klemmrollen (8, 9) klemmend in Eingriff genommen wird. Die vorliegende Erfindung betrifft ferner ein entsprechend hergestelltes Core-Garn (11).The present invention relates to a ring spinning machine (1) and a method for producing a core yarn (11), wherein a clamping device (6) with clamping rollers (8, 9) which contact one another in a clamping line (7) is provided by a drafting system (5). leaving the fiber structure (2) and at least one thread (4), in particular endless filament, to be fed to the fiber structure (2), and the clamping line (7) is passed through at least one of the clamping rollers (8, 9) running around the peripheral surface (12). Groove (13) is interrupted, which receives the at least one thread (4) as it passes through the clamping device (6) and leads past the clamping line (7) without it being engaged in a clamping manner by the mutually contacting clamping rollers (8, 9). . The present invention further relates to a correspondingly produced core yarn (11).
