Abstract
Drive device for electric sewing machine, comprising an electric motor (3) whose shaft (11) has a motor roller (12) intended for driving a flywheel (8) capable of becoming integral with a main horizontal shaft (4) of the machine, characterized in that it comprises a transmission roller (13) between the motor roller (12) and the flywheel (8), this transmission roller (13) being fixed to a mobile support (16) subjected to the action of a force which tends to keep the transmission roller (13) in contact, on the one hand, with the motor roller (12) and, on the other hand, with the flywheel (8), the transmission roller (13) being arranged in such a way that the friction effort between it (13) and the motor roller (12), during the running of the machine, tends to compress it between it (12) and the flywheel (8), tending the drag on the side of the flywheel (8) to separate the transmission roller (13) from the motor roller (12) for stopping.
