Abstract: An isolated drive assembly that includes a drive member, which is rotatable about a rotational axis, a drive member hub, which is rotatable about the rotational axis relative to the drive member, an isolator assembly, which has an elastomeric element that transmits rotary power between the drive member and the drive member hub, and a torque limiter. The torque limiter has first and second sets of engagable limiter elements that limit rotation of the drive member relative to the drive member hub in opposite rotational directions to limit a magnitude of a moment that is transmitted through the elastomeric element.

Abstract: A method and apparatus for transferring relatively thin, strip-like workpieces, such as metal leadframe strips to at least one processing or bonding station are proposed. The apparatus essentially comprises a transfer mechanism, a processing or bonding station, an electromotive drive, a first and a second group of electromagnetically, pneumatically or hydraulically operable clamping elements. The first group of the clamping elements is movable relative to the second group of clamping elements fixed to a main carrier of the transfer mechanism. In a first phase of the transfer and feed movement, the electromotive drive is controlled by means of reference geometry data given in dependence upon a particular leadframe and in a second phase of the feed movement by means of dynamic, opto-electronically measured reference data and pulses formed therefrom. The supply movement of the leadframe to the processing or bonding station takes place in a transfer direction (X') at an angle (.alpha.
