摘要： A thread cutting process can be performed well for a lower thread wound around bobbins having different outer diameters. In thread cutting mechanism portions 20A, 20B, 20C of a lower thread winding device 10, two groove portions of an inner threading groove portion 32 and an outer threading groove portion 34 are formed on a holder 16. In the inner threading groove portion 32, one end portion is opened to one of an intersecting direction intersecting with a radial direction of the holder 16 at an outer peripheral portion of the holder 16 and another end portion 32A is located at an inner side of a small-diameter bobbin 50 in the radial direction. The outer threading groove portion 34 is located at an outer side of the inner threading groove portion 32 in the radial direction of the holder 16. In the outer threading groove portion 34, one end portion is communicated with the inner threading groove portion 32 and located at the outer side of a large-diameter bobbin 60 in the radial direction and another end portion 34A is located at the inner side of the large-diameter bobbin 60 in the radial direction.

摘要： The present invention provides an upper decoration mechanism and a sewing machine without requiring an operation of detaching the upper decoration mechanism from the sewing machine without reducing workability even when performing a double chain stitch not using a decoration thread. An upper decoration mechanism 2 provided on a sewing machine 1 includes an expansion retraction mechanism configured to switch a spreader 14 between an expanded state where the spreader 14 cooperates with needles 4, 5 and 6 for performing an upper decoration sewing and a retracted state where the spreader 14 is separated from the needles 4, 5 and 6.

摘要： A hand-drawn taste is created in the sewing pattern by adding an appropriate fluctuation to each stitch and the seam imparting comfort and warmth can be formed. In addition, the pattern formed by a plurality of collective patterns is created so that a connecting portion between the plurality of collective patterns is naturally fluctuated. In an added coordinate data creating unit 102M configured to create a new coordinate data by adding independent original values to the X-coordinate value or the Y-coordinate value in each of the coordinate data stored in the data storage unit 102 which stores a sewing order and the coordinate data of a needle location in association with each other, when the coordinate data of two sequential needle locations in the sewing order stored in the data storage unit 102 is the coordinate data of a final needle location of one collective pattern and the coordinate data of a first needle location of another collective pattern sewn immediately after the one collective pattern, the added coordinate data creating unit is configured to create the new coordinate data by adjusting the independent original values added respectively to the coordinate data of the final needle location of the one collective pattern and the coordinate data of the first needle location of the another collective pattern sewn immediately after the one collective pattern so that a connecting portion between the one collective pattern and the another collective pattern sewn immediately after the one collective pattern is connected smoothly.

摘要： An object is to reduce user burden. A path teaching data creation device 1 includes: a selection unit 24 configured to select, as a connection target curve, at least one further curve connected to an end point of a connection source curve that is a curve from which a connection is started, determine the selected further curve as the next connection source curve, and sequentially select a curve to be the connection target curve; and a path creation unit 25 configured to create the path teaching data based on the curves selected by the selection unit 24. When a plurality of further curves connected to the end point of the connection source curve are present, the selection unit 24 selects one of the further curves as the connection target curve based on a final tangent direction of the connection source curve and respective start tangent directions of the further curves.

摘要： A hand-drawn taste is created in the sewing pattern by adding an appropriate fluctuation to each stitch and the seam imparting comfort and warmth can be formed without remarkably losing the original style of the pattern. A data storage unit configured to store a coordinate data of a needle location and an added coordinate data creating unit configured to create a new coordinate data by adding independent original values respectively to an X-coordinate value or a Y-coordinate value for each of the coordinate data stored in the data storage unit are provided. The added coordinate data creating unit makes the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in one needle location same as the independent original values added respectively to the X-coordinate value or the Y-coordinate value of the coordinate data in the other needle location when a distance between the coordinate data of the one needle location and the coordinate data of the other needle location stored in the data storage unit is within a predetermined distance.
