Abstract
A model for the fragmentation of heavy quarks is proposed, based on a scheme used previously to calculate hadron structure functions. It embodies the hardness expected from the decay kinematics, and is consistent with 'reciprocity', which demands that the fragmentation function should be related to the hadronic structure function. It agrees with the data on c and b quark fragmentation, but its predictions for t and other very heavy quarks are significantly different from the model of Peterson et al., (1983), for example.
