A thread conditioner and cutter includes (a) a base unit with (i) a planar divider for supporting a thread conditioning composition; (ii) a plurality of upper sidewall segments spaced apart from each other to define upper slots extending upwardly from the planar divider as well as defining an upper cavity of the base unit; (iii) a lower sidewall extending downwardly from the planar divider thereby defining an underside cavity, wherein the lower sidewall has a plurality of opposing thread notches at an upper edge thereof at a lower end of the upper slots of the upper sidewall segments as well as a pair of opposing lower slots extending upwardly from a lower edge of the lower sidewall; and (iv) a cutting blade disposed at one of said opposing slots at a first distance from the lower edge of the lower sidewall and wherein the slot opposed to the slot with the cutting blade extends a second distance from the lower edge of the lower sidewall which is greater than the first distance from the lower edge of the lower sidewall of the cutting blade.

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.

In a sewing machine, a plurality of needle plate holes are formed in a needle plate. The needle plate holes are arranged at positions respectively corresponding to a plurality of blade-side rotation positions of a cutwork blade. In this manner, the needle plate hole is formed in a shape corresponding to a shape of a blade portion, and a direction of the needle plate hole can match a direction of the blade portion that is arranged above to face the needle plate hole. Specifically, a linear hole-side cutting surface corresponding to a blade-side cutting surface of the blade portion is formed in the needle plate hole, and the blade-side cutting surface and the hole-side cutting surface can be arranged to face each other in a direction orthogonal to both the surfaces in a plan view.

In a needle plate, a needle plate hole is configured to include a hole-side cutting side that cuts a cutting target object together with a blade portion, and a relief side that allows a cut portion of the cutting target object to escape. Specifically, the needle plate hole has the hole-side cutting side that shears the cutting target object together with a blade-side cutting side of the blade portion, and the relief side that forms a gap between the blade portion to be inserted and the relief side. In this manner, in the former stage of cutting processing, the cutting target object can be cut by the hole-side cutting side and the blade-side cutting side.

A sewing or looping device for closing a tubular knitted article includes a body, two needles, a yarn support, and a cutting unit; the body has two spaced bases, the two needles are pivotally connected to the first base, respectively, and pivoting movement paths of the two needles are orthogonal to each other, the yarn support has a first section adjustably disposed on one of the bases, and a second section extending along an axial direction. The cutting unit is pivotally connected to the base where the yarn support is located. A cutting direction of the cutting unit is parallel to the axial direction, and the sewing chain stitch is pulled to the cutting point by the hook member and cut thereat. The sewing chain stitch assumes a tensioned state when being pulled, which in turn allows the sewing chain stitch to be cut more reliably and easily.
