  • Patent number: 6591769
    Abstract: The invention relates to a device for adjusting a checking unit of a presser foot, used in a sewing or embroidery machine. A needle bar moves the presser foot towards a needle plate, using a spring which is connected in series. The checking unit intercepts the presser foot using a checking element of the unit, before contact is made with the work piece to be sewn and controls the movement of the presser foot until the latter touches the work piece. The checking element and the needle bar are both operated by a common drive and the bedding position of the checking element can be modified in relation to the needle plate.

  • Patent number: 5755168
    Abstract: The invention relates to a sequin delivery system (1) for embroidery and/or sewing machines, in which a pusher (6) delivers sequins (3) from a sequin strip (2), which is at least partly guided laterally, in increments to a needle penetration point (24). A drive mechanism periodically moves the pusher (6) toward and away from the needle penetration point (24), and the pusher (6) has a slaving device, which on the motion of the pusher (6) in the direction of the needle penetration point (24) engages a hole (4) in a sequin (3). The pusher (6) is at least partially elastic, and in particular is a leaf spring, and presses the sequin strip (2) against a contact pressure plate (8).
