Abstract:
A sewing machine acquires a selected pattern that is selected from among a plurality of embroidery patterns. The sewing machine displays a pattern image representing the selected pattern. The sewing machine identifies a specified position indicated by the instruction. The sewing machine determines, when the selected pattern is acquired a plurality of times, whether one of a plurality of the pattern images is displayed at the identified specified position. When it is determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which the pattern image is displayed at the specified position as the editing target. When it is not determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which a mask region encompassing the selected pattern is set at the specified position as the editing target.
Abstract:
A data preparing apparatus includes an input device for inputting coordinate data such as a configuration and pattern to be processed and processing conditions, a memory device for converting the coordinate data inputted by the input device into variable coordinate data varying relatively according to the processing conditions and storing the variable coordinate data as a pattern data for processing, a predicting device for predicting a processing information resulting from a processing performed on the basis of the pattern data stored in the memory device and an output device for outputting the processing information obtained by the predicting device. The processing information includes at least one of a processing time, an area to be processed and a processing path. The predicting device calculates a processing time according to a preset processing rate.
Abstract:
A control device for sewing machines which includes a drive system controller which controls each of numerous driving units provided in the sewing machine and which is connected to an optional command system controller that is positioned outside of the sewing machine. Thus, a control code from the outside command system may be input and decoded to control the drive system controller.
Abstract:
A sewing machine 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 operation of the sewing machine. .[.By means of simple, strong modules of an advantageous price, even an unskilled operator can select and recall any number of stitch sorts in a simple and safe way when the module with the desired sort of stitch is inserted and the corresponding number is selected..].
Abstract:
A sewing machine for and a method of stitching a mark of a predetermined shape onto a fabric, in which the mark is stitched onto the fabric by selective employment of stitch patterns stored in a memory device of the sewing machine and wherein selected patterns form a single pattern of stitches corresponding to the predetermined shape of the mark.
Abstract:
A method and apparatus for detecting an improper stitch for a Class 400 chainstitch sewing machine. A monitor assembly determines the consumption per stitch of the looper thread during the formation of the chainstitches. A processor identifies times when the monitored consumption is indicative of looper thread consumption per stitch below a predetermined threshold value. Since the consumption per stitch for looper thread is nominally a predetermined multiple of the stitch length, those identified times correspond to times when improper stitches have occurred.
Abstract:
An apparatus of a sewing machine for indicating elongated pattern length is disclosed, wherein memory means normally stores a number of pattern data for forming the stitches of different patterns with a standard stitch amplitude and a standard fabric feed pitch, pattern selection means is selectively operated to select a desired pattern from the pattern data storing memory, amplitude setting means is optionally operated to set the amplitude value of the selected pattern, indication means indicates an amplitude value of the selected pattern set by the amplitude setting means, pattern elongation setting means is optionally operated to set a pattern elongating magnification value, discrimination means judges whether the selected pattern is elongatable or not, and means is provided for displaying the pattern elongating magnification value in the indicating means.

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. By means of simple, strong modules of an advantageous price, even an unskilled operator can select and recall any number of stitch sorts in a simple and safe way when the module with the desired sort of stitch is inserted and the corresponding number is selected.
Abstract:
Sewing operations are automated, at least partially, using a controllable sewing machine. In an intial recording phase for the sewing operation to be effected, there are put into memory the instantaneous values of three sensed parameters, i.e. the elapsed time of sewing, the position of a sewing speed control element and the length of the sewing, at each time the position of the speed control element changes under the action of the operator. Then, in a reproduction phase, the time is detected in continuous fashion, as is the distance sewn, and the position of the speed control element is changed at each moment for which the time detected is equal to a time recorded, or for which the length sewn is equal to the length recorded.
Abstract:
A sewing control system for a sewing machine which comprises a count circuit for counting signals synchronized with the rotation of the sewing machine, a memory circuit for storing a reference value, a comparator circuit for comparing said reference value with the output value from said count circuit, an initializing circuit for initializing said count circuit only when there is a comparison output from said comparator circuit after said reference value is stored, and a circuit for outputting a sewing finish signal as data on the number of the works sewn only when there is a comparison output.
