发明名称 Low inertia tandemly mounted presser mechanism
摘要 This invention relates to a presser mechanism for sewing machines which includes a pair of independently tandemly mounted presser foot soles arranged to cooperate with the feed mechanism of the machine in advancing the workpiece along a directed path of travel. Different selectively variable pressures may be applied to the presser foot soles such that both a firm heavy pressure and a resilient lesser pressure is applied to the workpiece as it travels along its directed path of travel.
