Mich. Admin. Code R. 408.12756 - Feed rolls
Rule 2756.
(1)
A feed roll on a planing, molding, sticking, or matching machine shall be
guarded by a hood or suitable guard to prevent the hands of the operator from
coming in contact with the in-running rolls at any point. The guard shall be
fastened to the frame carrying the rolls so as to remain in adjustment for any
thickness of stock.
(2) Surfacers
or planers used in thicknessing multiple pieces of material simultaneously
shall have sectional infeed rolls with 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 the yielding sectional rolls, suitable section
kickback finger devices shall be provided at the infeed end.
