Abstract: A drive arrangement for the drive elements for the threading of the upper thread into the eye of a sewing machine needle is provided. Instead of individual drives for lowering the threading device and rotating it as well as threading the thread regulator to deflect the upper thread around the thread brake, drives not used at that time for the needle rod, the presser foot pressure, and the thread brake are utilized. In this way, two to three additional electric drives can be omitted and thus the controlling expense can be reduced.

Abstract: An embroidery module (1) is provided that is attached (docked) to the base plate (29) of a sewing machine (27) and supplied with power and control commands from the machine electronics. A free space (33), which permits the insertion of tubular work pieces around the free arm (31), is created between the embroidery module (1) and a front end of the free arm (31). The embroidery module (1), with or without an embroidery hoop support (13), can remain docked for all sewing, embroidery, and quilting work on the sewing machine (27).

Abstract: A sewing accessories box includes a bottom part, as a set-up base, a back wall, a front wall, which is designed as a door, two side walls, a deck and interior shelves, which serve as receiving shelves for receiving accessories, such as bobbins or presser feet for a sewing machine. Each individual accessory is able to be retained in a holding and transport position on the receiving shelf so that, by way of actuation by a release key or by a swivelling movement of an individual accessory, the accessory can be moved from its holding and transport position into a removal position.

Abstract: An apparatus for embroidering surface-shaped sewing material includes an embroidery device which is connected, via an intermediate insertion of a distance adapter, to the column or free arm of a sewing machine. By inserting the distance adapter between the embroidery device and the sewing machine the distance between the embroidery device and the free arm or the column of the sewing machine is increased, which makes it possible to use an embroidery frame having a cross-sectional surface which is significantly greater than an embroidery frame which is able to be used if there was simply a direct connection between the embroidery device and the free arm or column of the sewing machine.

Abstract: A driving apparatus for an oscillating catcher of a sewing machine includes a toothed pinion being eccentrically mounted on a driving shaft for the catcher for the sewing machine. A transmission device, having teeth, is guided in a back-and-forth movement by an oscillating crank drive, with the teeth of the transmission device engaging the tooth pinion on the driving shaft. By arranging the toothed driving gear eccentrically on the driving shaft of the catcher, it is possible to substantially increase the speed of the point of the catcher when it seizes the loop of the upper thread offered by the needle.

Abstract: A spool capsule for a sewing machine for receiving a lower thread spool, having a concentrically disposed bore for mounting the spool capsule on a spool carrier pin, with a spring, serving as a locking device for axially retaining the spool capsule on the spool carrier pin, being inserted into a spool receiving space of the spool capsule. A section of the spring is constructed so that it is elastically displaceable radially, relative to the concentrically disposed bore, penetrating the bore in a manner analogous to a tendon. The locking device includes only a single movable element, which serves for both arresting the spool capsule on the pin of the spool and as an actuating device. This single element includes a spring, which is retained in a centrally-extending groove in a deepening of the spool capsule, and projects outwardly, at one point, through an opening in the surface of the spool capsule.

Abstract: A sewing machine having an adjustable head module, which has a machine body and a machine housing, along with a support plate for supporting a workpiece, and a support arm. Driving device for driving a looper in a looper system in the support plate, and for a needle bar in the adjustable head module at the end of the support arm is provided. The head module is pivotably mounted on the support arm, and pivotable, or swinging, about a horizontal pivot bearing in a first sewing direction and axially displaceable in a second sewing direction, in which the first and second sewing directions are perpendicular to one another. The head module can be adjusted on the body of the sewing machine in the sewing direction and transversely to the latter in a simple manner and locked into the exactly adjusted, and optimal, position.

Abstract: An electronic sewing machine is equipped with interfaces (6, 7, 8, 9) by which additional stitch or stitch pattern data can be introduced into a changeable memory of the sewing machine. This conception makes possible that the user of the sewing machine is able to store afterwards, i.e. after having acquired the sewing machine, a selection of preferred stitch types or stitch patterns according to individual wishes, and then to fetch such data without need for any external auxiliary means.

Abstract: An extension arm (11) can be fixed to a column (2) at any height and with different inclinations. A foot holder (15, 16) is displaceably mounted on the extension arm and can be moved against the force of a traction cable (8) over the extension arm (11). A loading unit (4) programmable by means of an operating device (21) for selecting the load characteristics acts upon the traction cable. Alternatively, another extension arm for arm training can be mounted. Thus, different training varieties can be selected without the need of adjusting any weights or mechanisms. Different extension arms (11) may be provided which allow the adaptation of the apparatus to different training modes, such as leg, arm or body training.

Abstract: A device for the quick and uncomplicated design of any sewing pattern or embroidering pattern permits creation of a raw draft of the pattern (11) on a graphic display (8). The raw draft is stored and the stored shape is used as a basis for elaboration and adaptation to the realization by the sewing machine. The elaboration and transformation into stitch sequences is also performed on an appropriate display (10), with the raw draft being displayed in the manner of a background. The transformation into individual stitches necessary during the editing process is largely automated by different auxiliary functions without excluding manual corrections.

Abstract: An electro-optical display serves for the display of basic types of stitch patterns or individual stitch patterns, e.g. zig-zag sewing, buttonholing, alphanumeric characters and the like. A cursor 13 can be moved to the displayed stitch pattern groups by means of a control device, and a menu comprising different stitch patterns of the selected stitch pattern group can then be selected and displayed by pressing an OK button. The particular desired stitch pattern group or the stitch pattern can then be selected from this menu or another menu which is displayed when an advance command is given. This hierarchical, stepwise display and selection of a determined stitch pattern group or an individual stitch pattern substantially simplifies and accelerates the selection from a great number of available stitch types or patterns.

Abstract: In the quilting machine the loosely superposed cover material webs and at least one filler material web, while being drawn into the quilting machine, are joined along their marginal portions by means of joining devices which are arranged laterally of the superposed webs. The web sections or selvedges lying outside the formed seams are separated and removed.

Abstract: A sewing maching having associated modules which can be inserted at will and which are interchangeable in a guide of the housing of the machine. The front side of the plate-shaped modules is visible in the inserted condition of the module and is provided with stitch symbols to which are assigned numbers. On the inside of the modules are arranged memories, preferably in connection with a microprocessor, which are in connection with the microprocessor of the sewing machine when the modules are inserted. By means of keys and a display, the number corresponding to the desired stitch sort can be selected and the control data from the memories of the module will be recalled in the microprocessor of the sewing machine and then used for controlling operation of the sewing machine.

Abstract: An overlock sewing machine wherein a thread which breaks between the shuttle and the looping discs is allowed to bypass the loop stripping device and is advanced by the discs toward and against the cutting edge of a knife provided on one leg of the U-shaped thread guide which confines the looping discs. This prevents the discs from convoluting the broken thread onto the shaft which drives the discs.

Abstract: The instrument has projections with locking teeth for locking the instrument in its closed clamping position, said projections being located near the connecting zone between the levers of the instrument and their ring grips. Near one projection a slide having a wedge surface is provided, which may be shifted between the projections against spring force by pressure onto a key of the slide, for spreading appart the projections and for disengaging their locking teeth. Disengagement of the locking teeth and opening of the closed instrument are substantially facilitated by simple and inexpensive means which do not hinder operation of the instrument.
