Abstract
In a sewing machine, a pivotable lever is provided in accordance with the present invention which carries a presser foot which is brought by an actuating device from a low position to a high position. In the low position the foot is applied to the material to be sewn. In the high position the foot is spaced from the material. The lever is equipped with rolling members which rest on guide ramps. The members and ramps have a profile such that during displacement of the presser foot between its two positions, the foot always follows a vertical path.
