The pion cloud surrounding the nucleon and the ..delta.. is studied in the soliton bag model. The quark-antiquark substructure of the pion is fully taken into account using generator-coordinate techniques. The one-gluon-exchange piece of the model Hamiltonian is responsible for creating the q-italicq-bar pair. The results we obtain for various hadronic properties are in good agreement with experimental data and qualitatively similar to those obtained in the cloudy bag model.
