Abstract: An invention is provided which employs a self-adjusting core section having an outer diameter which essentially matches that, or is larger than that, of the inner diameter of a wire coil, where the self-adjusting core has a vertical slit along the its length to allow the diameter of the core to be adjustable. Bridging the vertical slit are straps secured to the core to determine the core's maximum diameter, and allow the core diameter to be reduced through flexing.

Abstract: A miniature cord reel device comprising latch mechanism, where the latch mechanism is realized with a top flange, a bottom flange, attached on both ends of a core, a rotating sleeve, two projections on both sides of the cutout on the sleeve, a groove with groove notches on the top flange and the bottom flange.

Abstract: A device for guiding a web includes a frame, a first angle bar angled with respect to the entering web direction and supported by the frame for movement along a first path, the first angle bar having a first and a second side, a second angle bar angled with respect to the entering web direction and supported by the frame for movement along a second path, and a roller for changing a direction of the web between the first angle bar and second angle bar, the roller being moveable along a third path so as to be movable laterally beyond both the first side and second side of the angle bar.
