ABSTRACT:
An embroidering machine with a mounting device for individual embroidery hoops is provided with a design in which each individual embroidery hoop is always mounted with the same holding force and is always brought into the correct position for the start of the embroidery process. To ensure the three-point mounting of the individual embroidery hoop, which consists of an inner hoop and an outer hoop surrounding it, with the fabric to be embroidered located between them, the mounting device comprises two opposite holders, one of which has two contact surfaces enclosing an angle for fitted support surfaces of the outer hoop, and the other holder having a bow spring with a depression for a projection arranged on the outer hoop on the bisector of the angle enclosed between the contact surfaces. If the outer hoop is transversely slotted and its ends are connected by a turnbuckle, symmetrical expansion of the outer hoop independently of the thickness of the fabric to be embroidered will be achieved due to the fact that the turnbuckle is arranged in the axis of symmetry of the contact surface at the bow spring of one holder and the contact surface or contact surfaces of the opposite holder.
