The invention relates to a button hole sewing machine comprising a base plate (2), an upper arm (1) and a stand (3) which connects the arm (1) to the base plate (2) . Said machine also comprises a needle (6) which can be displaced back and forth and a clasp for the items to be sewn (9b), which can be displaced in direction-y, in addition to a button hole cutting device (13), comprising a cutter (36) which is arranged on the base plate (2) and which is provided with a linear cutting part (37) extending in the direction-y, and an eye cutting part (38) arranged on one end. Said machine also comprises a cutting block (15) which co-operates with the cutter (36) and a cutting drive (16) for displacing the cutting block (15) in a vertical direction-z counter to the cutter (36). The cutter (36) and the cutting block (15) can be adjusted in a parallel manner in relation to each other.

A punching device is provided with a punching head, a vacuum apparatus (50), a suction flow passage, and a suction switching apparatus (V). The punching head includes a plurality of hollow rods that move vertically, and punching tools each having an axially extending through hole provided at each front end of the hollow rods. The vacuum apparatus (50) serves to suck punched chips generated during the punching process of the punching head. The suction flow passage communicates the through holes of the punching tools with the vacuum apparatus (50). The suction switching apparatus (V) changes a path of the suction flow passage so that the suction flow passage communicates only with a hollow rod performing a punching process, among the plurality of hollow rods.

Eine Nähanlage hat eine Nähmaschine zum Vernähen eines Zusatz-Nähgutteils mit einem Basis-Nähgutteil. Die Nähanlage hat eine Nähgut-Auflageplatte. Eine Nähgutklammer mit zwei Klammerabschnitten (9a, 9b) dient zum Niederhalten von Nähgut jeweils auf einer Seite einer zu erzeugenden Naht gegen die Nähgut-Auflageplatte. Mindestens eine Abstands-Einstelleinrichtung (97a, 97b) dient zur Vorgabe eines Abstandes zwischen den Klammerabschnitten (9a, 9b) quer zu einer Nährichtung (2). Die Abstands-Einstelleinrichtung (97) hat ein Einstellrad (98). Mit dieser Nähanlage lassen sich verschiedene Betriebsverfahren realisieren, bei denen die Abstands-Einstelleinrichtung zum Einsatz kommt. Es resultiert eine Nähanlage, bei der eine Flexibilität bei der Durchführung eines Nähvorgangs vergrößert ist.

The invention relates to a buttonholing machine (1). The buttonholing machine (1) includes stress detecting means (20) for detecting a stress (σn) applied to a knife (11) when forming a buttonhole, cumulating means (20) for cumulating, each time the buttonhole is formed, the stress (σn) detected by the stress detecting means (20) to calculate a cumulated stress (Σσn), storing means (24) for storing a threshold stress (σa) that causes a wear-out or a breakage of the knife (11), and informing means (66) for informing a user of a replacement of the knife (11). When the cumulated stress (Σσn) reaches the threshold stress (σa) or before the cumulated stress (Σσn) reaches the threshold stress (σa), the control means (20) controls the informing means (66) to inform the user of the replacement of the knife (11).

摘要:
Eine Nähmaschine hat ein Gehäuse (6) und mindestens ein Messer (24) zum Schneiden von Nähgut oder zum Schneiden eines Nähfadens. Mit dem Messer (24) wirkt ein Gegenmesser (16) zusammen. Dieses ist als Messerplatte ausgeführt, die in einer Gegenmesserhalterung gehalten ist. Das Gegenmesser (16) ist in mindestens zwei verschiedenen Orientierungen in die Gegenmesserhalterung einsetzbar. In jeder dieser Orientierungen wirkt eine von mehreren, den Orientierungen zugeordneten Gegenmesser-Schneidkanten (23) mit dem Messer (24) zusammen. Es resultiert eine Nähmaschine, bei der mit kostengünstig herstellbaren Gegenmessern eine im Vergleich zum Stand der Technik höhere Schneidleistung bzw. Standzeit erbracht werden kann.
摘要:
A tape waste collector assembly (C1, C2) is suited for use with a belt loop sewing machine (M) having a tape cutter (12) for cutting a length of tape (T) placed on a tape receiving plate (15a, 15b) into pieces of a predetermined length so that each of the pieces of tape may be sewn on a garment to form a belt loop. The tape waste collector assembly (C1, C2) includes an air source (54), one or more air pipes (1, 61, 63) pneumatically connected to the air source (54) for blowing compressed air supplied from the air source (54) towards the length of tape (T) placed on the tape receiving plate (15a, 15b), and a plurality of tape waste collecting elements (3, 5, 6, 7, 28, 65, 70, 71, 72, 73) such as, for example, a hose (5, 7, 70, 72), a waste box (28, 73) and the like for collecting tape wastes (T1, R, L) produced when the length of tape (T) is cut by the tape cutter (12). A controller (50) controls a plurality of solenoid valves (53, 57) to operate the air pipes (1, 61, 63) and the plurality of tape waste collecting elements (3, 5, 6, 7, 28, 65, 70, 71, 72, 73) so that the tape wastes (T1, R, L) blown off by the air pipes (1, 61, 63) are appropriately collected by the plurality of tape waste collecting elements (3, 5, 6, 7, 28, 65, 70, 71, 72, 73).
