A sewing machine includes a drive frame mounted on the table of the sewing machine and at least two Y-direction drive mechanisms arranged at a spacing in the right-and-left directions of the sewing machine for driving the drive frame in the back-and-forth directions of the dewing machine. The sewing machine includes an upper frame erected over the table. Each of the Y-direction drive mechanisms includes a rail mounted on the upper frame and extending in the back-and-forth directions of the sewing machine, a moving portion mounted on the rail slidably in the back-and-forth directions of the sewing machine and jointed to the drive frame, and a drive portion for driving the moving portion in the back-and-forth directions of the sewing machine.

A sewing machine with an embroidery stitching function is disclosed, wherein a needle is vertically reciprocated to form stitches on a work held by an embroidering frame (19) which is moved in X-Y directions by a frame moving device relative to the needle on a working surface (2a) of a working bed (2), the frame moving device being composed of composed of a first mechanism (A) for moving said embroidering frame in the Y direction and a second mechanism (B) for moving the embroidering frame in the X direction, the first mechanism (A) being located on the working surface and connected to the embroidering frame (19) and the second mechanism (B) being housed in the sewing machine, the first mechanism (A) being moved by the second mechanism (B) to one end of the working bed (2) where the first mechanism (A) is rotated to a retreated position at the time of carrying out the ordinary stitching operation.
摘要:
In the sewing machine, a sewing device forms an embroidery pattern on a work cloth in cooperation with a moving mechanism. A display switching device switches the display between a first display mode and a second display mode. Therefore, the sewing machine can selectively display the size value representing a size of the embroidery pattern or the position value representing a position of the embroidery pattern on the work cloth using the display as desired. Further the display is necessary to secure a space for displaying both the size value and the position value at once. Accordingly, the sewing machine display can be downsized without sacrificing the convenience of the display.
摘要:
A method for stitching one work piece to another or for stitching a decorative stitch line along a work piece. In one embodiment, the method includes plotting a line on a first work piece, arranging the first work piece so that at least a portion of the first work piece overlies or abuts at least a portion of a second work piece, and then stitching the first work piece to the second work piece along the plotted line with a computer controlled sewing apparatus having a machine vision system to facilitate stitching along the plotted line. In some embodiments the first and second work pieces are portions of a shoe. Also, in some embodiments the line is plotted on the first work piece in ultraviolet ink.

A process for folding or folding over pockets with round edge sections is provided along with a device for carrying out the process. Round folding slides (9; 53), provided with concave folding edges (49; 54), are either moved or designed such that their ends (50, 51; 55), either one after another or simultaneously, lead in relation to the middle area of the concave folding edges (49; 54). An especially intense folding effect is thus exerted on the transition areas between the round and straight pocket edge sections and a pocked folded edge that is uniform on all sides is thus obtained.
摘要:
A sewing machine includes a movable holder portion which holds a material to be sewn, a holder drive portion which transfers the holder portion during sewing, a needle drive portion which drives a sewing needle to sew, and a controller which intelligently regulates the holder drive portion and the needle drive portion. The controller includes a) an initial motion device which initially transfers the material to be sewn before sewing or during an initial stage of sewing, and b) an estimating device which finds the mass of the material to be sewn depending on a physical value such as at least one of a moving velocity of the material to be sewn at a predetermined period of time and a moving distance of the material within the amount of the predetermined period of time.

A sewing machine includes a frame for supporting a fabric to be sewn and a drive device for moving the frame. The drive device includes an X-drive mechanism for moving the frame in X-direction and a Y-drive mechanism for moving the frame in Y-direction that is perpendicular to the X-direction. Each of the X-drive mechanism and the Y-drive mechanism preferably includes a linear motor as a drive source. A machine table is positioned below the frame. The linear motor of each of the X-drive mechanism and the Y-drive mechanism is disposed below the machine table.

In a display apparatus used for a sewing machine, a liquid crystal display, LCD, shows a pattern edit screen in which a pattern is edited. The pattern edit screen has a standard display area for displaying the pattern for editing. The standard display area has a vertical long rectangular shape and is smaller than a half of the screen. When the image key is pressed on the pattern edit screen, the LCD is switched from the standard display area to a magnification display area, and the pattern is magnified and displayed thereon. The magnification display area is substantially as large as the whole of the display area of the LCD. Thus, the pattern can be displayed in greater detail. Furthermore, shading can be added to the pattern displayed. Therefore, each piece of thread can be presented, which makes the image of the formed pattern more realistic.

A belt-loop sewing machine which is capable of efficiently supplying belt loops, includes a bending-shaft-movement-locus control means which controls such that a forward movement locus GML, through which paired bending shafts of a loop supply means are moved toward a sewing position, and a backward movement locus BML, through which the paired bending shafts are moved apart from the sewing position, are made to be different from each other.
