Abstract
A headgear frame apparatus adapted to be removably attached to a drive frame adapted to be driven transversely and longitudinally of a sewing machine and extending transversely. The headgear frame apparatus comprises: a mounting base frame attached removably to the front side of the drive frame and adapted to be driven transversely and longitudinally together with the drive frame; a support frame connected to the mounting base frame such that it is driven with the mounting base frame longitudinally but not transversely; a rotary frame supported rotatably on the support frame; a headgear frame fitted removably on the rotary frame for clamping a headgear; and a rotation converting member interposed between the mounting base frame and the rotary frame for converting the transverse motions of the mounting base frame into rotations of the rotary frame. The mounting base frame includes a guide face confronting a drive frame front face of the drive frame from the front and extending transversely. One or more front bearing roller for abutting against the guide face and one or more rear bearing roller for abutting against the drive frame front face are rotatably borne on the support frame respectively.
