摘要： A cutting device on a sewing machine for cutting a tape or tape-like lace comprising, a first blade which is disposed on a swingable blade guide and which has a cutting edge which cooperates with the cutting edge of a further second blade secured to a holder. The cutting device has a feed device, provided with a shaft for feeding the tape or tape-like lace, the arrangement being such that the cutting edge of the blade on the swingable blade guide is movable in a substantially cylindrical path of swing about the center of swing of the blade guide, and such that the cutting edges of the blades are inclined towards one another when in a cutting position, the holder for the further blade being situated within the cylindrical path of swing of the cutting edge of the blade disposed on the swingable blade guide.

摘要： A sewing machine has a tape feeder for laterally aligning pre-positioned tapes of different widths at a presser foot (38) with a presser foot sole (4), the presser foot arranged in such a way that it can move up and down. Several guide elements (15) constructed in the form of lamallae (34) and aligned in the tape feed direction are fitted in the tape in-feed region on the presser foot sole (4). These guide elements (15) guide the tapes laterally.

摘要： A tape feeder for at least two tapes (8,11) which can be taken from a stock is arranged on a sewing machine. The tape feeder has a controlled feed-in device (12) which is arranged transversely to the workpiece feed direction (16), in such a way that it can move, and which has a motor driven shaft (13), which transports tape as desired to the presser foot (6) on the sewing machine. A cutting device (14) arranged on the feed device (12) enables the tapes to be cut off.
