    • A guide mechanism for the roller presser bar of a sewing machine of the type that includes an upper surface roller feeder for imparting movement to the upper work surface and a presser foot that cooperates with the feed dog. The guide mechanism for the roller presser bar is independent of the guide mechanism for the presser foot bar. The independent guide mechanism for the roller presser bar avoids binding of the roller presser bar that occurs when a common guide mechanism is utilized for both the roller presser and the presser foot bar. The roller presser bar guide mechanism includes a pair of movable vertically aligned surfaces attached to the bar and a cooperating block attached to the sewing machine housing with a pair of adjustable guide plates.
    • 一种用于缝纫机的辊压杆的引导机构,该引导机构包括用于向上工作表面传递运动的上表面滚轮进给器和与进给爪配合的压脚。 滚子压杆的引导机构与压脚杆的导向机构无关。 用于滚子压杆的独立引导机构避免了当使用公共导向机构用于滚筒压脚和压脚杆时发生的滚子压杆的装订。 辊压杆引导机构包括一对可移动的垂直对齐的表面,其连接到杆上,以及配合块,该配合块通过一对可调导向板附接到缝纫机壳体。
