Publication number: 20060283366Abstract: A method and the device for minimizing stitching faults in embroidery devices (1) is provided, which includes a drive for moving the material holder (13), with an article to be sewn (11) being stretched therein, based on the knowledge that such stitching faults frequently can be explained by oscillations of the article to be sewn (11) and the material holder (13) due to rapid accelerations. Various effects, such as different types of articles to be sewn, changing weights, and friction ratios can cause a change of the oscillation behavior. One or more sensors (29, 43, 44) are provided and arranged such that they can detect the oscillation of the article to be sewn (11) and/or the material holder (13). The control of the drive and/or the sewing needle (23) occurs depending on the detected oscillations such that deviations of the stitching site from the predetermined target value is minimized.Type: ApplicationFiled: June 8, 2006Publication date: December 21, 2006Applicant: FRITZ GEGAUF AKTIENGESELLSCHAFT BERNINA-NAHMASCHINENFABRIKInventors: Gerard Durville, Otmar Stillhard

Patent number: 4817547Abstract: 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.Type: GrantFiled: January 25, 1988Date of Patent: April 4, 1989Assignee: Fritz Gegauf AG Bernina-NahymaschinenfabrikInventors: Alfred Gaeumann, Otto Hangarter, Otmar Stillhard

Patent number: 4667614Abstract: For the adjustment of the values for the length and width of the stitches there is provided rotative adjustment knobs, each of which permitting to set a counter through an incremental sensing device. The state of the counter serves for controlling the machine and an analog display consisting of a luminous beam. From a storage unit basic adjustment values for determined sorts of stitches may be introduced in the counter and utilized unchanged or arbitrarily modified for controlling the display. The adjusted value effective for controlling the machine and the basic adjustment value are displayed in a different manner on each display. This gives as a whole a diversified, pleasant to handle and clear adjustment and display.Type: GrantFiled: August 15, 1985Date of Patent: May 26, 1987Assignee: Fritz Gegauf AG Bernina-N/a/ hmaschinenfabrikInventors: Otto Hangarter, Otmar Stillhard

Patent number: 4622910Abstract: The button hole presser foot engages longitudinally slidably in a frame like slide which is taken along with the sewing material. The slide comprises a cord stretched in the longitudinal direction which encircles the lower end of a shaft of the presser foot shank. At the top end of the shaft is provided an impeller through which a light beam of a light source emerges toward a optoelectric transducer. During the sewing operation the slide moves with the sewing material and it drives the impeller which generates pulses each corresponding to a step of the motion of the sewing material, respectively of the slide. For determining the length of the cords, a determined number of steps, respectively of pulses is counted each time. This permits a reliable and precise determination of the length of the cords.Type: GrantFiled: June 18, 1985Date of Patent: November 18, 1986Inventors: Otto Hangarter, Hansulrich Lerch, Otmar Stillhard

Patent number: 4586448Abstract: A foot control of the sewing machine can be actuated from a neutral position in two directions. In one case, a variable resistance becomes effective which produces regulating voltages within a determined range. A logic circuit with comparators produces for this voltage range a condition in which the driving motor of the sewing machine is controlled to operate with a number of turns corresponding to the voltage range. When the machine is stopped the needle is automatically positioned in its upper stop position. By repetitive actuation backward of the foot pedal the needle may be positioned in its bottom stop position and again in its upper stop position and so on. The logic treatment of the control signals from the foot control permits to transmit these signals for all required instructions through a two wire cable which is already required for the speed control.Type: GrantFiled: October 25, 1983Date of Patent: May 6, 1986Assignee: Fritz Gegauf AG Bernina-NahmaschinenfabrikInventors: Hansueli Lerch, Otmar Stillhard

Patent number: 4384241Abstract: A sewing machine drive having a mains rectifier (1) which, via a chopper (2) operating at a relatively high frequency, supplies direct current pulses to the driving motor (3). The duty ratio of these driving pulses is controlled as a function of a nominal value transmitter (11) and a current limiting circuit (14) controlled by the motor speed. This produces a smooth quiet, vibration-free operation of the motor (3) or the driven machine with a high degree of motor efficiency. Moreover, a speed-dependent current limitation occurs in such a manner that at high speeds a limited maximum current flows, which at the same time results in an output limitation.Type: GrantFiled: October 17, 1980Date of Patent: May 17, 1983Assignee: Fritz Gegauf Aktiengesellschaft Bernina-NachmaschinenfabrikInventor: Otmar Stillhard

Patent number: 4343256Abstract: A sewing machine having a torsion spring coupling between drive and machine shaft. An engageable catch pawl acts on a stop element connected to the drive, which stop element is connected to the drive side of the coupling spring of the drive. If the catch pawl is engaged with the machine in operation and the stop element is blocked, the coupling spring is released and hence the coupling disengaged. The motor may then run down while the motor shaft is stopped resiliently in a predetermined position via the coupling spring which simultaneously the coupling spring prevents excessive forces from occurring due to inertia and excess stressing. Hence this construction permits the motor to be stopped rapidly from full operation with simple means.Type: GrantFiled: May 19, 1980Date of Patent: August 10, 1982Assignee: Fritz Gegauf AG Bernina-NaehmaschinenfabrikInventors: Armin Neuweiler, Otmar Stillhard
