摘要： Pattern display data and embroidery data are stored in a card ROM that is usable in a sewing machine. Based on the pattern display data, a predetermined number of embroidery patterns are displayed in a display unit mounted on the sewing machine. After a desired embroidery pattern is selected, an operator may depress a stitching time key if he or she wants to know a stitching period of time for the embroidery pattern selected. When the key is depressed, the stitching period of time is computed based on the corresponding embroidery data stored in the card ROM. The resultant stitching period of time is displayed in conjunction with the selected embroidery pattern. As such, the operator can recognize the stitching period of time before start of embroidery stitching.

摘要： A device and method for continuously regulating the amount of thread stripped from a supply spool and fed to a sewing needle during embroidery is provided. In commercial embroidering, the lengths of consecutive stitches can vary widely. The invention allows the machine to apply optimal tension to all embroidery stitches, regardless of their differing lengths. Pulling all stitches under optimal tension improves the appearance of the finished stitches and reduces the breakage and fraying of the thread. In the preferred embodiment of the invention, a digital computer controls a programmable servomotor, which in turn regulates the action of the embroidery machine's take-up and driver lever. The take-up in turn regulates the length of thread stripped from the supply bobbin and fed to the current stitch. In an alternative embodiment, the take-up and driver lever are replaced by a wheel, which is connected to the servomotor.

摘要： An under thread supply apparatus for a sewing machine comprises a bobbin case, a bobbin exchange device, a thread removal device and a winding device. The bobbin case is removably set to a shuttle of the sewing machine and accommodates a bobbin with the thread wound thereon. The bobbin exchange device takes the bobbin case out of the shuttle, and sets the bobbin case accommodating the bobbin with the thread wound anew therearound to the shuttle. The thread removal device removes the thread from the bobbin accommodated in the bobbin case which is taken out. The winding device winds a preset amount of thread around the bobbin after the thread is removed therefrom.

摘要： A method and apparatus for indexing the waistband of trousers into belt loop attachment positions at the stitching station of a sewing machine is disclosed. A stepper motor is drivingly engaged to an indexer clamp, which engages the end portion of the waistband. The stepper motor drives the indexer clamp and pulls the waistband through the stitching station. A detector detects the presence of a waistband seam and signals a controller which correlates the position of the side seam as a reference point with the desired attachment positions of belt loops. The controller signals the stepper motor to stop when each of successive belt loop attachment positions move into the stitching station. The controller operates a belt loop delivery system which feeds a belt loop to the stitching station. Work holding clamps secure the belt loop onto the waistband. The belt loops are stitched onto the waistband as each successive belt loop attachment position enters the stitching station.
