§4423. Paper Machines.

(a) An audible alarm shall be sounded prior to starting up any section of a pulp or paper machine. Sufficient time shall be allowed between activation of the alarm system and start-up of the equipment to allow any persons to clear the hazardous area.

(b) Feeder belts, carrier ropes, air carriage or other equally effective means shall be provided for starting paper into the nip of drum type reels.

NOTE: 1: A rope-carrying system should be used whenever possible at points of transfer.

NOTE: 2: Sheaves should be spaced so that they do not create a nip point with each other, and the sheave and its support should be capable of withstanding all intended forces.

(c) To remove deposits from rolls, a specially designed hand-held scraper tool shall be used.

(d) Scraping of rolls shall be performed on the outgoing nip side.

(e) Reels shall stop rotating before being lifted away from the reel frame.

(f) All lifting equipment (clamps, cables, and slings) shall be maintained in a safe condition and inspected regularly.

(g) All drum winder nip points shall be guarded.

NOTE: Machines should be set up with the drums running outward.

(h) All winder shafts equipped with a winder collar guide shall have a guide rail to align the shaft for easy entrance into the opened rewind shaft bearing housings.

NOTE: If the winder is large and the rewind shafts are too heavy for manual insertion, powered rewind shaft injectors should be employed.

(i) Core collar set screws used for the securing of core collars to winding and unwinding shafts shall not protrude above the face of the collar. All edges of the collar with which an operator's hand comes in contact shall be beveled to remove all sharp corners.

(j) Shaftless winders shall be provided with a barrier guard of sufficient strength and size to confine the rolls in the event they become dislodged while running.

(k) All calendar stacks and spreader bars shall be grounded as protection against shock induced by static electricity.

(l) All exposed sole plates between dryers, calenders, reels and rewinders shall have a non-skid type surface.

(m) When a powered roll ejector is used, it shall be interlocked to prevent actuation until the receiving platform or roll lowering table is in position to receive the roll.

(n) Unless counterbalanced to prevent falling, the rider roll shall be secured when in the raised position.
