A sewing machine acquires embroidery data of the embroidery pattern formed from a plurality of partial patterns. The sewing machine selects, as a selected partial pattern, at least one partial pattern from among the plurality of partial patterns forming the embroidery pattern, on the basis of the acquired embroidery data. The sewing machine identifies, on the basis of the embroidery data, an outline of the selected partial pattern that was selected. The sewing machine generates processing data for performing processing following the shape of the selected partial pattern, on the basis of the identified outline.

A cutting system includes a sewing machine and a cutting device. The sewing machine includes a sewing portion, a sewing communication portion, a sewing processor, and a sewing memory. The sewing machine acquires an embroidery data stored in the sewing memory. The sewing machine sends, via a network line, the acquired embroidery data. The cutting device includes a cutting portion, a cutter communication portion, a cutter processor, and a cutter memory. The cutting device receives, via the network line, the embroidery data sent by the sewing machine. The cutting device generates a cutting data based on the received embroidery data. The cutting device drives the cutting portion based on the generated cutting data, and cuts the object to be cut.

The present invention provides a thread feeding device of a decorative stitching sewing machine. The thread feeding device feeds a needle thread, an upper looper thread, and a lower looper thread in the amounts required for sewing one stitch such that the position of a stitch looping point of the threads changes. The thread feeding device includes: a thread accumulator 500 having thread accumulating elements 13a to 13d and 14a to 14d which measure the thread accumulation amounts of predetermined lengths of the needle thread, the upper looper thread, and the lower looper thread, and thread accumulation amount control elements 15 to 18 which adjust the amounts of the threads required for sewing one stitch in an increasable and decreasable manner within the range of thread accumulation amounts of predetermined lengths at the time of fabric feeding, and which release the threads to a stitch forming device when a stitch is formed; a thread feed drive mechanism 600 which drives each of the elements; and a thread feed control unit having a program which dives the thread accumulation amount control elements for each stitch to feed the threads in an increasable and decreasable manner so as to increase or decrease the threads within the range of a total thread feeding amount that is maintained constant, including a fabric feeding amount, a fabric thickness and an overlocking width, thereby to change the position of the stitch looping point of the needle thread, the upper looper thread, and the lower looper thread, thus controlling the decorative stitching according to a stitching decoration pattern.

With an overlock sewing machine set to an interlock state and the upper blade in an interlock position, upon turning the operating shaft toward one side around its axis, an interlock switching mechanism displaces the other end portion of a rod and sets an interlock release state. A pressing portion presses a first switching portion to swing a swing member toward the forward swing side, which displaces the upper blade to retraction position. With the state set to interlock release with the upper blade in retraction position, upon turning the operating shaft toward one side around its axis, the pressing portion presses a second switching portion to swing the swing member toward the reverse swing side, which displaces the upper blade to interlock position. The interlock mechanism displaces the other end portion of the rod to set the state to interlock.

An overlock sewing machine includes an operating shaft that is slidable between first and second positions, and configured such that interlock switching and position switching mechanisms are operated when it is turned. The interlock switching mechanism includes a rotor that is rotatable together with the operating shaft as a single unit, an interlock switching member, and a first engagement target portion formed in the rotor. In the interlock state, setting the operating shaft to the first position engages an engagement portion of the interlock switching member with the first engagement target portion, which restricts operating shaft rotation. Sliding the operating shaft to the second position releases the engagement state between the engagement and first engagement target portions, enabling rotation of the operating shaft.
