R 408.16374 Nip points.

Rule 6374. (1) An inrunning nip point on a roll-type embosser, drum winder or rewinder shall be guarded by a barrier interlocked with the drive mechanism in such a manner that the barrier can be raised only when the rolls have stopped. The interlock system may allow the use of a jog switch when the barrier is open. The barrier shall be constructed so that an employee cannot reach over or around it into the nip point. (2) A nip point, which is not a feeding point, created at calender or dryer rolls shall be guarded by a barrier. (3) A nip point, which is a feeding point, shall be fed by a device, such as but not limited to a rope carrier, air jet or a tool, or guarded by a barrier which will keep the employee's fingers from the nip point while feeding. A hand-held device capable of going through the nip point shall not be used. (4) An employee shall be cautioned as to an unguarded nip point by a warning sign.
