FIELD: mechanical engineering for sewing industry. SUBSTANCE: the complex has a table cover for turning relative to the bed frame, carrying, for example, two stitching machines of different purpose, furnished with a base plate hinge-joined to the bed frame side members for turning in the vertical plane and retaining in the preset positions, carrying the flanges with balls and an axle on which the table cover is fitted; the bed frame side members are furnished with additional planes for their installation in the horizontal or vertical position; a hemispherical groove is made in the base plate, whose center is matched with the center of the axle of turn of the table cover, carrying a stop placed in the groove, fixing the table cover in the operating position of the stitching machines, and the base plate is fixed relative to the bed frame side members by a retainer, which presents a spring- loaded rod installed in the side member and entering the base plate hole under the action of the spring. EFFECT: improved design. |
