A core prevents a battery separator wound therearound 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.

Embodiments of the present invention are directed to recoilers, merchandise security systems, and methods for displaying and protecting an article of merchandise from theft. In one example, the merchandise security system includes a sensor configured to be secured to the article of merchandise and a base for removably supporting the sensor and the item of merchandise thereon. The system also includes a recoiler operably coupled to the sensor. The recoiler includes a rotatable member defining a helical recess. The system further includes a cable configured to connect to the sensor and to be unwound from and wound on the rotatable member as the cable is extended and retracted. The cable is configured to be extended from the recoiler in response to the sensor being lifted off of the base, and the cable is configured to be retracted into the recoiler in response to the sensor being moved to a seated position on the base. The helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

A method of grooving a durable transfer roll core may comprising loading the durable transfer roll core onto a grooving apparatus and grooving a main surface of the durable transfer roll core via engagement with one or a plurality of cutting tools of the tooling section of the grooving apparatus.

A system for carrying a tether guide, including a counter-balanced support system with two pivot points, where a first pivot allows the tether guide to travel up and down and the second pivot allows the tether guide to match the tether angle. Both pivots may be passive pivots. A shuttle that carries the tether guide may be electronically cammed to follow variable pitch helical grooves of a winch drum as the tether guide traverses across the drum length.
