摘要： A sewing machine includes a housing (2) and a stitch forming tool (10) for forming a seam, wherein the stitch forming tool includes a needle bar (9) maintaining a sewing needle (10). A thread lever (34) of the sewing machine guides an upper thread (28), and is synchronously operated with respect to the stitch forming tool (10) to be displaced between a top dead center and a bottom dead center. The sewing machine has upper thread guiding components (33, 35) disposed at the front and rear of the thread lever (34) at a passage of the upper thread. A thread passage pre-setting device (47) affects the length of the passage of the upper thread between an upstream upper thread guiding component (33) and the thread lever (34). The thread passage pre-setting device (47) has a protrusion element (48). The protrusion element (48) is disposed such that the upper thread (28) departs from a main guiding surface between the upstream upper thread guiding component (33) and the thread lever (34) and passes by. The main upper guiding surface is defined by the upstream upper thread guiding component (33), the thread lever (34), and a downstream upper thread guiding component (35). As a result, an improved thread passage pre-setting device may be obtained.

摘要： PURPOSE: A sewing machine is provided to convert transmission vibration motion occurred around a transmission vibration axis into the drive vibration motion of a looper vibration axis and to include a traction driver with a traction means, thereby reducing the mechanical stress about components. CONSTITUTION: A looper driver (14) comprises a drive unit (15) and a traction driver (26). The drive unit generates transmission vibration motion (16) around a transmission vibration axis line (17). The traction driver includes a traction means (25) and converts the transmission vibration motion occurring around the transmission vibration axis into the drive vibration motion of a looper vibration axis (13). The drive unit comprises a rotary drive shaft (5) and a crankshaft (18). One axis end (19) of the crankshaft is drive-connected with the drive shaft by an eccentricity unit (20). And the eccentricity unit is arranged in the drive shaft. The other axis end (21) of the crankshaft is connected to a transmission wheel and swings the transmission wheel backwards and forwards. The transmission wheel is mounted to a frame (5a) in order to circle around the transmission vibration axis.
摘要翻译：目的：提供缝纫机将变速器振动轴周围发生的传动振动运动转换成活套振动轴的驱动振动运动，并且包括具有牵引装置的牵引驱动器，从而降低组件的机械应力。构成：活套驱动器（14）包括驱动单元（15）和牵引驱动器（26）。驱动单元围绕传动振动轴线（17）产生传播振动运动（16）。牵引驱动器包括牵引装置（25），并且将在变速器振动轴线周围发生的变速器振动运动转换成弯针振动轴线（13）的驱动振动运动。驱动单元包括旋转驱动轴（5）和曲轴（18）。曲轴的一个轴端（19）通过偏心单元（20）与驱动轴驱动连接。并且偏心单元布置在驱动轴中。曲轴的另一个轴端（21）连接到传动轮并向前和向后摆动传动轮。传动轮安装在框架（5a）上，以围绕传动轴振动。
