摘要:
A thread can be captured surely by the thread capturing open eye of a needle and a stitch can be formed in the space within a machine bed. A handstitch on the front surface of a fabric workpiece and a locked stitch on the back surface are formed as a skip-stitch set by cooperation of a open eye needle (13), a rotary hook (200) comprising a rocking bobbin casing (205) loaded in a rotative outer rotary hook (202), and a thread draw out actuator (401). In the first stroke of the open eye needle (13), a stitch length feed of the fabric workpiece for handstitch is performed by a feed dog (601). In the second stroke of the open eye needle (13), an inter-stitch pitch feed of fabric workpiece for inter-handstitch is performed by a feed dog (601).
摘要:
Disclosed is a three-dimensional textile product (1) comprising two surfaces (2, 3) that are connected by means of a plurality of stitching threads (10, 20) which are sewn through said product. Each stitching thread has a succession of stitches (11) which each encompass two segments (12, 13) that penetrate the product from one surface to the other. The disclosed textile product (1) is characterized in that the same comprises at least two distinct types of stitching threads (10, 20) and in that for each type of thread, at the level of a stitch, the plane formed by the thread segments (12, 13; 22, 23) penetrating the product features a perpendicular direction (N1; N2) which has a non-zero inclination (α1, α2) relative to the general sewing direction D of the stitching thread (10), said inclinations (α1, α2) of the planes differing from one type of thread to the other.

Chain-stitch sewing machine includes: a looper provided under a needle plate and having a thread lead-in port and thread lead-out port, the looper being rotationally driven in synchronism with a sewing operation; a plurality of thread feed ports connecting to different thread supply sources; and a connecting member having a thread passage, the connecting member selectively connecting any one of the plurality of thread feed ports to the thread insertion port of the looper via the thread passage. Threading mechanism passes the sewing thread, fed via the thread feed port connected by the connecting member to the thread insertion port of the looper, into the thread insertion port and causes the sewing thread to be taken out via the inserted thread lead-out port of the looper.

A sewing thread (20) can be captured certainly with a thread capturing open eye (13a) of an open eye needle (13) and the stitches are formed in the inner space of a sewing machine bed (3). A handstitch and a locked stitch are formed, respectively, on the front surface and the back surface of a fabric workpiece (21) as a skip stitch set through cooperation of the open eye needle (13), a shuttle hook (200) and a thread draw out actuator (401). A feed dog (601) feeds the fabric workpiece by a stitch length (P1) for handstitch during a first stroke of the open eye needle (13), and feeds the fabric workpiece by an inter-stitch pitch (P2) between the handstitches during a second stroke of the open eye needle (13).

Bei einer Kettenstichnähvorrichtung mit einem parallel zu einer Nähgutebene (12) bewegbaren Nähkopf (10), umfassend eine Nadelstange (20) für eine einen Faden führende Nadel (22), einen Nadelantrieb (24) zum geradlinigen Hin- und Herbewegen der Nadelstange (20) quer zur Nähgutebene (12), einen mit einem offenen Fanghaken (30) versehenen nadelförmigen Fadenfänger (26) und einen Fängerantrieb (29) zum geradlinigen Hin- und Herbewegen des Fadenfängers (26) quer zur Nähgutebene (12), wobei die Bewegungsbahnen der Nadel (22) und des Fadenfängers (26) einen spitzen Winkel α miteinander bilden, dessen Scheitel S unterhalb der Nähgutebene (12) liegt und wobei der Nadelantrieb und der Fängerantrieb so gesteuert sind, daß eine beim Zurückziehen der Nadel (22) aus dem Nähgut (14) unterhalb desselben gebildete Fadenschlaufe (32) von dem Fadenfänger (26) erfaßt und durch das Nähgut (14) nach oben gezogen wird, ist dem Fadenfänger (26) ein antreibbarer Fadenzieher (36) zugeordnet ist, der einen quer zur Bewegungsbahn des Fadenfängers (26) in den Weg der an dem Fadenfänger (26) hängenden Fadenschlaufe (32) bewegbaren Arm (40) hat und dessen Antrieb so gesteuert ist, daß der Arm (40) nahe der oberen Stellung des Fadenfängers (26) die an dem Fadenfänger (26) hängende Fadenschlaufe (32) quer zur Bewegungsbahn des Fadenfängers (26) nach der der Hakenöffnung entgegengesetzten Seite auslenkt.
摘要:
Method and needle for reinforcing a cellular material (1), wherein the method comprises: producing a through-hole (2) in the cellular material (1) that extends from a first surface of the cellular material (1) to a second surface of the cellular material (1); reaching through the through-hole (2) from the first surface of the cellular material (1) to the second surface of the cellular material (1); taking hold of at least one fiber bundle (3) at the second surface of the cellular material (1); and pulling the at least one fiber bundle (3) into the through-hole (2) in the cellular material (1); wherein producing the through-hole (2) in the cellular material (1) includes perforating the cellular material (1) with a rotating and/or oscillating needle (8).
