A bobbin carrier of a sewing machine is suspended in a surrounding plate solely by several radial pins bridging the space between the carrier and the plate and which can be successively temporarily retracted from the space by a rotating cam. A hook turning with the cam takes up thread from a needle and drives it about the bobbin carrier, in synchronization with retraction of the pins, for the formation of a stitch with a thread fed from a bobbin in the carrier.
