摘要:
The present invention includes a sewing machine (12) with a variable top feed mechanism (25) that feeds the top layer of material for a sleeve at a variable rate to change the fullness thereof. The machine (12) is driven by a motor (42) which is controlled by a controller (51). A program is taught to the controller (51) for storage therein. The controller (51) then controls both the motor (42) and a controller (45) for the top feed mechanism to regulate the number of stitches and the relative rates of speed for the top and bottom materials fed by the machine. The program initially is taught to the machine and can be utilized for any type of material or size by inputting the correct sizes and types of material on a control panel (44). The machine (12) therefore semi-automatically sews sleeves onto armholes with the correct fullness sewn therein.

The invention relates to a sewing machine comprising a device for steering towards a predetermined end (E) of a seam (B1). According to the invention, the alternating movement of the feed elements of the sewing machine, which occurs when the stitch adjusting device is set, is taken into consideration in the calculation of the target stitch length (Sb) of the final, optionally shortened end stitch (NRe) of the seam, in such a way that a setting value that deviates from the target stitch length is produced.

Bei einer Nähmaschine wird die drehzahlabhängige Stichlängenveränderung durch eine drehzahlabhängige Korrektur der Einstellung der Stichstellvorrichtung kompensiert, so daß sich eine geradlinige Stichlängen-Sollwertkurve Ss ergibt.
摘要:
A sewing unit that can be easily provided, either initially or subsequently, with retaining and folding means (28, 31) for pockets that are to be folded, or with receiving and retaining means (33, 34; 36, 37) for pre-folded pockets, enabling folded or pre-folded pockets to be sewn in a selective manner.

Für das Sticken von aus Teilmustern zusammengesetzten Kombinationsmustern auf Näh- oder Stickmaschinen mit einem angetriebenen Stickrahmen wird zum exakten Positionieren der Teilmuster am Ende des ersten Teilmusters und am Anfang des zweiten Teilmusters je ein außerhalb der Musterkontur liegender gemeinsamer - als Anhängepunkt dienender - Nähstich gebildet, dessen Verbindungsfäden zum eigentlichen Muster nach Fertigstellung des zweiten Teilmusters entfernt werden.

Bügelmaschine mit einer Einrichtung zum Befeuchten des Bügelgutes. In der Wasserzufuhr zum Dampferzeuger (22) ist eine Ionenaustauscherpatrone (25) zur Beeinflussung der Wasserqualität angeordnet. Außerdem ist eine Steuereinrichtung (28) zur Signalgabe (35) und/oder Abschaltung der Pumpe (20) zur Zuführung des Wassers an den Dampferzeuger bei Erschöpfung der Ionenaustauscherpatrone vorgesehen.
摘要:
A lamp comprises a light source and a light guide (17), which is guided over part of its length in the housing (1) of a sewing machine and projects at one end (18) outside the housing (1). The lamp is arranged in the sewing machine so that it can illuminate any part of the machine as desired, without detriment to the operator's working region or visual field. For this purpose, the end (18) of the light guide (17) is shaped to match a housing part (7) which accommodates and conceals it on the side facing away from the housing.
摘要:
Defective stitches frequently occur at the beginning of a stitching operation with a sewing machine provided with needle feed, because the starting threads are not tightly gripped in the needle plate as a result of the elongated stitching slot. In the new process, the needle (13) is positioned prior to the beginning of stitching in an end region (S1) of the stitching slot (50b) in order to execute a predetermined number of starting stitches.

The control circuit (15) of a catch thread device has a counter (22) for the main shaft of the sewing machine. The counter (22) counts the number of revolutions of the main shaft (26) during the reception of one of at least two signal intensities and is reset to its initial value when this signal intensity changes to the other signal intensity. When a predetermined maximum number of revolutions is reached, the counter (22) emits a signal indicating a thread fault.
