ABSTRACT:
Work feeding mechanism and a rotatable loop taker are provided for a sewing machine in a module wherein a rock shaft connects with a feed bar through a flat spring enabling a feed dog on the feed bar to be moved by camming means in a direction perpendicular to the work feeding direction as the feed dog is moved in the work feeding direction by the action of the rock shaft. The camming means which is disposed under the feed bar is located in line with the feed dog to minimize inertia effects and guiding means associated with the feed bar maintain the feed dog level as the feed dog is moved in the work feeding direction and perpendicular to it.
