Abstract
Machines and related methods are disclosed for dispensing a rolled fabric over spaced support beams of a roof and for holding the fabric firmly in place over such beams to protect workers from falling through the gaps between the beams. The machines may include one, some, or all of several different components and features to enhance the system's overall operation and effectiveness. One aspect relates to a hub brake used to help prevent unwinding of the fabric roll in the event of a fall. Another aspect relates to a magnetic brake to help keep the machine from sliding across the support beams in the event of a fall. Another aspect relates to a guide assembly that engages a support beam with a one-directional bearing to also help keep the machine from sliding in the event of a fall.
