A cord reel assembly including a single, continuous cord having stationary and retractable segments, with the stationary segment including multiple connectors and sheath covering such connectors where the connectors twist and untwist relative to the sheath in response to the retract and extension of the retractable segment.

A core prevents a battery separator wound there a round from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.

Provided is a self-retracting device including a rotatable hub assembly. The rotatable hub assembly includes a first half and a second half. The first half includes a slot for an axle. The second half includes a retraction member and a slot for the axle. The self-retracting device also includes an axle with a body extending through the slot of the first half and the slot of the second half and a line. A first end of the line includes a loop, wherein the loop is between the first half and the second half and the axle body extends through an opening defined by the loop. The rotatable hub assembly is configured to retract the line when the rotatable hub assembly moves in the first rotational direction and pay out the line when the rotatable hub assembly moves in a second rotational direction opposite the first rotational direction.

A cable spool includes first and second curved flanges extending radially outwardly from first and second axial ends of a drum. The flanges have outer edges that cooperate to define an annular slot providing access to a passageway surrounding the drum. The slot has a width that is less than half the height of the drum. A cable is wrapped around the drum. A closure having an environmentally sealed interior may receive an end of the cable. A second cable can be deployed from a second spool and coupled to the end of the cable within the closure. The second spool can be mounted with the cable spool. A cover can be placed over the spools for aesthetic or protection reasons.

The present invention discloses a sheet winding structure to reduce indentation transfer occurring because of sheet thickness or adhesive colloidality of the innermost layer of the sheet. The sheet winding structure comprises: a winding core having an outer surface, wherein the outer surface of the winding core comprises a recess thereon; and a sheet winded over the outer surface of the winding core, wherein a beginning portion of the sheet is disposed in the recess.

A mounting system for supporting equipment above a surface, such as, for example, a label dispensing unit, is provided. The system includes bracket having a first segment cantilevering from a housing and a second segment extending perpendicularly from the first segment and spaced apart from the housing. The housing and first and second segments form a channel to receive a support structure therein. The support structure is sized to fit within the channel to support the equipment above a surface when the bracket is disposed over the support structure.

A method of laying an optical fiber comprises providing a continuous optical fiber, a first segment of optical-electrical hybrid cable having a first fiber receiving tube, and a second segment of optical-electrical hybrid cable having a second fiber receiving tube. The optical fiber is laid into the first fiber receiving tube using an air-blowing device. A leading end of the optical fiber is fixed in a transfer apparatus after the leading end passes through an outlet of the first fiber receiving tube. A portion of the optical fiber which has passed through the first segment is wound in the transfer apparatus until the optical fiber is completely laid in the first segment. The leading end of the optical fiber is detached from the transfer apparatus. The portion of the optical fiber which has passed through the first segment is laid into the second fiber receiving tube using the air-blowing device.
