    • 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.
    • 针移Z字形单元和工作进给单元在必要时移动到不同位置,用于连续的针迹,以形成缝合图案。 每个单元由缝纫机的主旋转驱动轴供电。 然而,每个单元都设置有相应的步进电机。 每个步进电机改变由主驱动轴驱动的往复运动发电机中的调节器的设定。 当这些调节器中的一个处于恒定设置时,只要驱动轴旋转,其各自的往复运动发生器连续地产生恒定相应振幅的往复运动,持续无限制的时间。 通过连续地改变由两个往复运动发生器执行的往复运动的振幅来建立缝合图案的穿刺坐标。 与缝纫同步地读出静态存储器,以提供命令步进电机的信息,使往复运动发生器的幅度调节器从一个振幅设置非常快地移动到另一个,从而以这种方式建立所有连续的针 - 穿透坐标甚至复杂的缝合图案。

    • The stitch-control-signal outputs of a first memory are connected to the inputs of stitch-forming instrumentalities via an intermediate second memory. One of the two memories is a static memory which is read out by applying to the address signal inputs thereof a series of next-address signals derived from the signals produced at the output of that memory. Both memories may be static memories whose read-out is performed in that way. Alternatively, the intermediate memory may be a sequential-access dynamic memory, such as a shift register, whose read-out is effected by a train of indistinguishable shift signals. In the latter event, the read-out of the first memory is effected by applying to the address-signal inputs thereof a series of next-address signals derived from the output signals of the first memory and not performed in synchronism with machine operation, whereas the read-out of the dynamic sequential-access second memory is performed in synchronism with machine operation but without addressing codes and instead by trains of indistinguishable signals. The information read out from the intermediate second memory is written into it either from the first memory or alternatively from an external pattern data reader, such as a perforated-tape reader.
    • 第一存储器的针脚控制信号输出经由中间第二存储器连接到针迹形成工具的输入。 两个存储器中的一个是静态存储器,其通过向其地址信号输入端应用从该存储器的输出处产生的信号导出的一系列下一地址信号来读出。 两个存储器可以是静态存储器,其读出以这种方式执行。 或者,中间存储器可以是顺序存取动态存储器,例如移位寄存器,其读出由一列不可区分的移位信号实现。 在后一种情况下,通过向地址信号输入施加一系列从第一存储器的输出信号导出并且不与机器操作同步地执行的下一地址信号来实现第一存储器的读出,而 动态顺序访问第二存储器的读取与机器操作同步地执行,但是不寻址代码,而是通过不可区分的信号列。 从中间第二存储器读出的信息从第一存储器或从外部图案数据读取器(例如穿孔磁带读取器)中被写入。

    • 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.
    • 缝纫机的电子图案形成系统包括由大量可单独寻址的存储位置组成的主模式存储器。 代替每个存储位置仅存储一个图案的一个针迹的针脚控制数据,至少一些存储位置中的每一个的一个部分存储与一个图案的一个针迹有关的缝合控制数据,但是具有相同的另一个部分 存储位置存储与不同针迹相关的针脚控制数据,例如完全不同图案的针迹。 因此,对于一些存储的图案,用于图案的每个存储位置的一个部分存储针杆位置命令,每个这样的存储位置的另一部分存储布料进给命令。 然而,如果布料指令无论如何都相同,一个接下来,对于图案的每个针迹,这些存储位置的第二部分不会浪费在该不变的送布指令数据的存储上,而是被使用 例如,用于存储完全不同的图案的针杆位置命令,其中不变的送布指令数据不是从图案存储器而不是从对应于图形存储器的辅助存储器施加到机器的送布单元,而是从辅助存储器 通过将这种图案的必要的不变的送布指令数据应用到机器的送布单元来选择该图案。

    • A drive motor drives a reciprocating sewing needle. A static memory has lateral-control-signal outputs at which it furnishes signals indicating how much the needle should be laterally shifted for each stitch in a selected pattern, and feed-control-signal outputs at which it furnishes signals indicating how much a work feeding device should feed the work for each stitch of the pattern. An addressing circuit response to a pattern selector applies to the static memory a repeated sequence of address signals, causing the memory to produce repeated sequences of lateral-control and feed-control signals at its outputs. The first address signal in any of the repeated sequences of address signals causes the static memory to produce at its output a first lateral-control signal constituting a maximum-speed-establishment signal, and a first feed-control signal constituting a maximum-permissible-speed signal. A latch receives the feed-control signals but does not in general register them, except when activated. A detector receives the lateral-control signals, and in response to the maximum-speed-establishment signal activates the latch which then registers the maximum-permissible-speed signal. A motor speed limiter limits the speed of the drive motor in dependence upon the signal registered by the latch.
    • 驱动电机驱动往复缝纫针。 静态存储器具有横向控制信号输出,在该控制信号输出端提供指示针对所选择的图案中的每个针脚应该横向偏移多少针的信号,以及馈送控制信号输出,在该输入信号输出端提供指示工作进给多少的信号 设备应为每个针迹的针迹馈送工作。 对模式选择器的寻址电路响应适用于静态存储器重复的地址信号序列,导致存储器在其输出端产生重复的横向控制和馈送控制信号序列。 任何地址信号的重复序列中的第一地址信号使得静态存储器在其输出处产生构成最大速度建立信号的第一横向控制信号,以及构成最大允许频率的第一馈送控制信号, 速度信号。 闩锁接收馈送控制信号,但通常不会注册它们,除非激活。 检测器接收横向控制信号,并且响应于最大速度建立信号激活锁存器,然后锁存器登记最大允许速度信号。 电机限速器根据锁存器登记的信号来限制驱动电机的速度。
