摘要： A pulse motor rotation phase adjusting system for a sewing machine includes a pulse motor operative for positioning a needle of the sewing machine in accordance with the predetermined stitch coordinates of a selected pattern. The pulse motor is adapted to be set to one of the stepping rotation phases in dependence upon the predetermined combinations of the magnetic forces generated by the windings of the pulse motor. A light interrupting arrangement is provided in the system which is connected to the output shaft of the pulse motor and serves for detecting the respective rotation phases of the pulse motor within a range of the maximum needle swinging amplitude and to produce a signal corresponding to predetermined combination of the magnetic forces, which signal is read out by a control circuit operatively connected to the pulse motor to rotate and reset the same to its initial position in accordance with said predetermined stitch coordinates when the electric power is applied to the sewing machine.

摘要： The electronic patterning system of a sewing machine comprises a main pattern memory consisting of a large number of individually addressable storage locations. Instead of each storage location storing only the stitch-control data for one stitch of one pattern, one section of each of at least some of the storage locations stores stitch-control data pertaining to one stitch of one pattern but with another section of the same storage location storing stitch-control data pertaining to a different stitch, e.g., a stitch of a completely different pattern. Thus, it may be that for some stored patterns one section of each storage location used for a pattern stores needle-bar position commands with the other section of each such storage location storing cloth-feed commands. However, if the cloth-feed commands would anyway be identical, one after the next, for each stitch of the pattern, the second sections of these storage locations are not wasted on storage of this invariant cloth-feed command data, but instead are used, for example, for storing needle-bar position commands of an entirely different pattern, with the invariant cloth-feed command data being applied to the cloth-feeding unit of the machine not from the pattern memory but instead from an auxiliary memory which responds to selection of this pattern by applying the requisite unvarying cloth-feed command data for such pattern to the cloth-feeding unit of the machine.

摘要： The invention concerns a sewing machine with an electronic pattern stitch control system which operates the stitch forming device to change the relative positions of the needle and the sewn material, thereby to form a pattern. Addressing signals are applied to the address inputs of the memory at a high frequency to cause the contents of the memory to be successively produced at its output terminals. Comparing means compare this data output to pattern identifying signals generated by the user operated pattern selection switches. The addressing signals continue to be applied until a matched comparison is reached whereupon the data is applied to the stitch forming means.

摘要： The needle-shifting zig-zag unit and the work feeding unit are moved to different positions, when necessary, for successive stitches, to form a stitching pattern. Each unit is powered by the main rotating drive shaft of the sewing machine. However, each unit is provided with a respective stepper motor. Each stepper motor changes the setting of an adjuster in a reciprocating-motion generator driven by the main drive shaft. When one of these adjusters is in a constant setting, its respective reciprocating-motion generator continually generates reciprocating motion of constant corresponding amplitude, for an unlimited time, so long as the drive shaft rotates. The needle-penetration coordinates for the stitching pattern are established by continually changing the amplitude of the reciprocations performed by the two reciprocating-motion generators. A static memory is read out, in synchronism with sewing, to furnish information commanding the stepper motors to move the amplitude adjusters of the reciprocating-motion generators from one amplitude setting to another, very quickly, to in this way establish all the successive needle-penetration coordinates for even complex stitching patterns.

摘要： Patterned stitching is produced by shifting the needle or work feed of the machine to different position coordinates. A motion-generating cam generates motion in a first path of motion. A transmission lever receives this motion and transmits it to the stitch forming instrumentalities. Positioning members move in synchronism with main shaft rotation in a second path of motion which is parallel to the first, and in doing so passes through different position-coordinate settings. Locking levers are activatable and releasable by solenoids for locking the positioning members in selected position-coordinate settings. A pattern-selecting unit operates in synchronism with main shaft rotation and selects the position-coordinate settings in which the positioning members are to be locked, and causes the locking levers to lock them in such settings.
