Abstract: A spool for photographic film has a generally cylindrical core with flanges at the end portions of the core. A slot through the core receives an end portion of the film that is to be wound onto the spool. Hooks in the slot are engaged with the film through apertures in the film for attaching of the film to the spool. In order to avoid locking of two spools together during bulk handling, as can occur when a flange of one spool enters the slot of another spool, the outer edge of one wall defining the slot is chamfered and generally V-shaped. The edge of the wall forms a large obtuse angle and is substantially aligned with the tip ends of the hooks so that the chamfered wall and the tip ends prevent a spool flange from becoming locked in the slot of another spool.

Abstract: An improved lid mechanism for a web feed devices such as tractors for feeding perforated paper webs in printers, copiers and the like, wherein pins on which the lid is pivotally mounted for movement between open and closed position are unloaded (do not have any force or bias applied thereto) when the lid is in its open and closed position. The lid, when closed, covers the paper and is then spaced by a gap from the surface of a frame along which the paper is fed by a pin drive such as a belt having pins which extend into perforations of the paper. A depending leg of the lid has a block with surfaces disposed at an angled to each other. These surfaces extend from a corner of the block. One of these surfaces is preferably perpendicular to the surface of the lid which defines the gap. The other of these surfaces defines the position of the lid in its open position.

Abstract: In a conventional vacuum box a loop of a web material is received in an elongate chamber of the box, and a vacuum at the lower portion of the chamber draws air through the chamber to hold the loop of web material under tension as it moves through the chamber. When the web has one or more notches along a side edge thereof, the web may vibrate excessively and experience a drop in web tension as the notch passes through the bottom of the loop in the box. In order to avoid this problem an endless ring of flexible material is positioned in the vacuum box and within the loop of web material. The ring has a plurality of spaced openings around the circumference of the ring, and they are offset from the side edges of the ring so that the portion of the ring adjacent the openings will cover the notches in the web as the web passes through the bottom of the loop in the vacuum box, thus avoiding the excessive vibration in the web and loss in web tension mentioned above.
