Abstract
A sewing machine is provided with a mechanism which is actuated by a drive unit and engages with a needle point insert. The mechanism moves a needle plate insert from a sewing position raised above a needle plate, in which the needle plate reinforces a fabric being clamped to a fabric holder, to a resting position not raised above the needle plate, in which the fabric holder may be moved and the fabric may be changed. The mechanism insures that this movement can be effected in a straightforward manner and with only slight wear and abrasion and while affording accurate transmission. The mechanism is fashioned as a straight-line mechanism with a first oscillating crank which is adjusted for setting the operating height of the needle plate insert and a separator crank for adjusting the insert between a rest position and an operating position.
