Improvements in machines for the manufacture of slide fasteners, characterized by comprising a fastening means, intermittently driven, to fasten fasteners to the strip of this, and a wheel feeder of the strip, intermittent rotation, which during each period of intermittent rotation describes a practically constant angle, at least during most of each complete cycle of intermittent rotations; and the clamping means is actuated between the periods of intermittent rotation, to clamp an element of the closure to the strip and, furthermore, because the periphery of the feed wheel of the strip, although continuous, has a part modified by the arrangement of a projection or a depression, so that the strip, when it is in contact with the modified part, during each period of intermittent rotation when describing the practically constant angle, a distance greater or less than the movement during another of said periods, when it is in contact with the unmodified part of the wheel.
