Abstract

Blindstichnähvorrichtung umfassend einen Nähkopf (10) mit einem Träger (20), einer an dem Träger (20) drehbar gelagerten Nadelwelle (34), die mit einem radial von ihr abstehenden Nadelhalter (36) zur Halterung einer bogenförmig um die Achse (38) der Nadelwelle (34) gekrümmten Nadel (40) verbunden ist, einen Nadelantrieb (56, 58, 44, 42) zum Hin- und Herbewegen der Nadel (40), einen an dem Träger (20) beweglich gelagerten Schlingenfänger (74) zur Aufnahme einer beim Zurückziehen der Nadel (40) durch das Nähgut gebildeten Fadenschlinge, einen Fängerantrieb zum Bewegen des Schlingenfängers (74) in zeitlicher Koordination mit der Bewegung der Nadel (40), und Mittel (14) zum Erzeugen einer Relativbewegung zwischen dem Nähkopf (10) und dem Nähgut, dadurch gekennzeichnet, daß der Schlingenfänger (74) für eine Hin- und Herbewegung quer zur Bewegungsbahn der Nadel (40) gelagert ist und daß die Mittel (14) zum Erzeugen einer Relativbewegung zwischen dem Nähkopf (10) und dem Nähgut so ausgebildet sind, daß die gebildete Naht mindestens annähernd in Richtung der Bewegungsbahn der kreisbogenförmig gekrümmten Nadel (40) verläuft.

Figure 00000001
Blindstitch sewing device comprising a sewing head (10) with a carrier (20), a needle shaft (34) rotatably mounted on the carrier (20), which with a radially projecting needle holder (36) for holding an arc around the axis (38) of the Needle shaft (34) curved needle (40) is connected, a needle drive (56, 58, 44, 42) for reciprocating the needle (40), a loop catcher (74) movably mounted on the carrier (20) for receiving a when the needle (40) is retracted by the thread loop, a catcher drive for moving the loop catcher (74) in time coordination with the movement of the needle (40), and means (14) for generating a relative movement between the sewing head (10) and the sewing material, characterized in that the loop catcher (74) is mounted for a reciprocating movement transverse to the path of movement of the needle (40) and that the means (14) for producing a relative movement between the sewing head (10) and the N hgut are formed so that the seam formed at least approximately runs in the direction of the movement path of the circular-arc-shaped curved needle (40).
