(d) Surfacers or planers used in processing multiple pieces of material simultaneously shall be provided with sectional infeed rolls having sufficient yield in the construction of the sections to provide feeding contact pressure on the stock, over the permissible range of variation in stock thickness specified or for which the machine is designed. In

lieu of such yielding sectional rolls, suitable section kickback finger devices shall be provided at the infeed end. § 50-204.217 Sanding machines.
