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.

A system includes a drum assembly that includes a support bar having a first end and a second end, and a plurality of drum segments coupled to the support bar. The drum segments are movable between retracted and extended positions, and the drum assembly is configured to be disposed within an interior region of a coil of flexible pipe when the plurality of drum segments are in the retracted position. The system also includes a first containment flange coupled to the drum assembly at the first end, a second containment flange coupled to the drum assembly at the second end, a first coupling device configured to removably couple the first containment flange to the drum assembly, and a second coupling device configured to removably couple the second containment flange to the drum assembly. The first and second containment flanges are configured to contain the flexible pipe.

Provided are a winding shaft, a cell manufacturing apparatus, and a cell manufacturing method. The winding shaft is used for winding plates and includes: a winding shaft body including a first winding surface; an adjustment member configured to be mounted to the winding shaft body and movable simultaneously in an axial direction of the winding shaft and in a radial direction of the winding shaft, where the adjustment member includes a second winding surface, and the first winding surface and the second winding surface are configured to wind the plates jointly; and an actuator configured to drive the adjustment member to move to change a relative position of the second winding surface with respect to the first winding surface, so as to change a winding circumference of the winding shaft. The winding shaft of the present application can reduce the possibility of or the amount of misalignment between the tabs.

A reel for storing a cable coil includes first and second facing flanges. First, second and third cylindrical rods define a hub and have first ends attached to the first flange and opposite, second ends extending through holes formed in the second flange. A guidepost has a first end attached to the first flange and a second end passing through an opening in the second flange. A lock set allows a distance between the first and second flanges to be selected. Attachment positions of the first ends of the cylindrical rods to the first flange are manually or automatically adjustable to change a diameter of the hub. Bushings within end openings of the guidepost control the rotation payout speed of the reel, and a parking park feature is provided at the second end of the guidepost to block rotation of the reel.

An adjustable height optical fiber cable reel comprises a first piece having a first base plate and a first tab protruding from the first base plate, the first tab having a first opening and a second opening, a second piece having a second base plate and a second tab protruding from the second base plate, the second tab having a pin. The pin is configured to engage the first opening to lock the adjustable height reel at a first height, and to engage the second opening to lock the adjustable height reel at a second height. The adjustable height reel may also be coupled to a slack storage tray. Optical fiber enclosures may also be configured with adjustable height reels with optional slack storage trays.

A spool has a first flange and a second flange. A barrel extends between the first flange and the second flange. A movable hub is located radially inward of the barrel. The barrel is axially wider than the movable hub and the movable hub is axially movable between a first operational position adjacent the first flange and a second operational position adjacent the second flange. The movable hub includes an axially-extending cantilevered detent arm forming a stop surface that limits axial movement of the movable hub toward one of the first flange and the second flange.

The present disclosure describes a cable reel. The cable reel may include a hollow core having a width; a first wall coupled to an end of the core and extending radially outward a distance from the core, the first wall comprising an opening aligned with the hollow core and at least one support member extending across the opening; and a second wall coupled to an opposing end of the core and extending radially outwardly a distance from the core, the second wall comprising an opening aligned with the hollow core; wherein the first wall and the second wall form a gap therebetween equal to the width of the core, the gap being configured to hold a length of excess cable wrapped around the core. Cable reel covers are also described.
