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.

A winding core covering (10) comprising a backing (45), the backing (45) having an adhesive layer (40) and a support layer (30) in contact with the adhesive layer (40), and a web contact layer (20) in contact with the backing (45), the web contact layer (20) including a thermoplastic polymer, where the outer surface (27) of the web contact layer (20) has a structured surface comprising a plurality of protrusions (25) having an average height (H) of 50 m to 600 m. A winding core (41) including the disclosed winding core covering (10).

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 delivery reel for an elongated sheet, having a disk-shaped flange member on which a sheet roll is positioned; an auxiliary core member of generally cylindrical shape split in the circumferential direction to enable expansion in diameter, and inserted into the inside diameter part of the sheet roll; a main core member fitted into the auxiliary core member which has been inserted into the sheet roll; and a stopper member attached to the circumferential edge of the flange member, and jutting toward the outside in the radial direction. The main core member has a plate spring. In a state in which the auxiliary core member has been inserted into the inside diameter part of the sheet roll, and the main core member has been fitted into the auxiliary core member, the plate spring presses the inside peripheral surface of the auxiliary core member toward the outside in the radial direction.

A coil component has a core including a winding core extending in a predetermined direction, and a winding wrapped around the winding core in two or more layers. A first winding portion at one end in the predetermined direction in an (n+1)'th layer of the winding, where n is a natural number, is positioned over a space between second and third winding portions in an n'th layer, the second and third winding portions being adjacently spaced in the predetermined direction.

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 cord winding mechanism for a blind cord with a first end fixed to a window blind includes a base, a cord winder rotatably mounted to the base, a cord guiding assembly mounted to the base, and an elastic press member mounted to the base. The cord winder defines an annular slot to wind the blind cord layer by layer. The cord guiding assembly is abutted against an unwound portion of the blind cord between the cord winder and the window blind. A second end of the blind cord is fixed to an end of the cord winder in the slot. The press member is elastically abutted against a portion of the blind cord just separate from the cord winder.
