UPWARD AND DOWNWARD FEEDING SEWING MACHINE

摘要

PURPOSE: An upright transferring sewing device is provided to adjust the current amount about the upper side solenoid or lower side solenoid in control means, thereby adjusting the pressure force of sewn material respectively by a roller. CONSTITUTION: Movement amount of a plunger is change according to the supplied current quantity in lower side solenoid. The lower side solenoid pressures the sewn object of lower side using the lower roller. In the upper side solenoid(10), movement amount of the plunger is changed according to the current amount. The upper solenoid is pressured the upper side sewn material using the upper roller. A controller controls the current amount which electrified to the lower solenoid and the upper solenoid individually.
