  • Apparatus according to claim 21 further including support means for said base material, and base material drive means operatively associated with said support means for stepwise movement of said base material laterally of the primary direction of travel of said distributor over said base material.
  • Apparatus according to claim 22 further including auxiliary drive means operatively associated with said distributor for periodically moving said distributor laterally of the primary direction of travel of said distributor over said base material.
  • Apparatus according to claim 22 further including auxiliary drive means operatively associated with said distributor for periodically moving said distributor to a modified extent with respect to the ordinary movement of said distributor in the primary direction of travel of said distributor over said base material.
