At the end of this module, you will be able to:
- Compare the operation and speed of a paper or board machine to a winder
- List devices and strategies that can be used to prevent accidents and injuries on winders
- Define the terms "pinch point," "nip point," "ingoing nip," and "outgoing nip"
- Describe how machine guarding types and locations are determined for a winder
- Identify the locations of pinch point hazards, nip hazards, cutting hazards, fall hazards, thermal burn hazards, and slipping and tripping hazards on a winder
- List important safety guidelines for overhead cranes
- List ways to improve safety for winder operator procedures
- List safe behaviors to use around winders
The following key questions are answered in this module:
Why must winders run so much faster than paper and board machines?
Because they must stop occasionally to load new reels, eject finished roll sets, reposition slitters, and change blades, winders must run much faster in order to keep up with the machine's production.
How can workers be protected from the fall hazard presented by broke holes (openings in the floor)?
Guards and/or covers on broke holes should be interlocked with light curtains or safety gates, and current fall protection guidelines must be followed when working around unguarded broke holes.
What kinds of hazards are presented by the hydraulic systems used by many winders and rewinders?
Hydraulic fluid is pressurized and is heated during operation. If a fitting or coupling were to come loose, the fluid would present burn, fluid injection, and fire hazards, as well as the hazards presented by any flailing lines or hoses.
What is recommended or required for platforms and catwalks around winders?
All walking surfaces should be slip-resistant, and elevated surfaces should be equipped with top-rails, mid-rails, and toe boards.
Do winders and rewinders have any cutting hazards?
The slitters and set change device (a cut off knife or guillotine) both present nip point and cutting hazards to operators.
Below is a transcript of the video sample provided for this module:
Most paper and board machines use overhead cranes to move parent reels from the machine to the winder or empty spools from the winder back to the machine. Crane loads can be heavy and do not react quickly to control changes, so the following safety guidelines apply:
•Do not operate a crane unless you have been trained to do so
•Visually inspect crane components and rigging, and test crane movements and alarms, on a regular basis; report all potential problems to a supervisor
