Abstract: An improved light-tight package for a roll of a length of web material such as photographic paper or film. The package includes an opaque leader wound around the roll. Folded-over portions of opaque tearable flexible end disks are held in place by adhesive tape strips. A rigid disk is positioned intermediate the end disks and the end surfaces of the roll. In a preferred embodiment, the adhesive tape is tearable and the leader includes a portion adapted to initiate a tear in the tearable tape and the end disks. Upon unrolling of the package by pulling the leader, the tape tears, and the end disks tear circumferentially, whereby the folded-over portions adhere to the leader when the leader separates from the roll, and the rigid disks provide support for the flexible end disks.

Abstract: A film package in which the carrier for a stack of film sheets inside a light-tight wrapper is improved to provide a rigid corner that resists being pulled into the printer when the wrapper is removed. The corner is achieved by a construction featuring a bottom panel, first and second side panels hingedly and integrally attached to adjacent side edges of the bottom panel, and a top panel extending from an edge of one of the side panels and permanently secured to the other of the side panels to define a rigid exterior corner, the top panel having dimensions such that it leaves exposed a portion of any film sheet and the bottom panel under the top panel.

Abstract: A package for enclosing a plurality of sheets of a photosensitive material. The package comprises a pouch for enclosing the sheets and a leader secured at one end of the pouch for removing the pouch from the sheets placed therein. The pouch includes a first laminate structure and a second laminate structure located in generally parallel planes. The first and second laminate structures each having an inner layer made of a first material and an outer layer made of a second material. The first and second laminate structures each having a leading edge and the first and second laminate structures being positioned such that the inner layers of the first and second structures face each other and the leading edge of the one of the laminate structures extends past the other leading edge so as to form an attachment section. The sheets being positionable between the first and second laminate structures. The leader is secured to the attachment section.

Abstract: A supply magazine for use in an apparatus for removing individual film that has been placed within a light-tight pouch having a leader secured to the leading edge. The magazine has a base which receives and retains a stack of sheet film within the light-tight pouch, and a cover secured to the base which can be rotated between a closed position and an open position. A take-up spindle is rotatably secured within the base for winding of the pouch thereon. The improvement comprises a lever arm for biasing the leader toward the spindle which cooperates with hook provided on the spindle when the cover is in the closed position. The lever arm includes a clamp pad which has a configuration which forms a resistive wall section in the leader when the magazine is in the closed position such that when the spindle is rotated, the hooks will engage the leader at the resistive wall section allowing the pouch to be wound around the spindle.

Abstract: A package for a stack of film sheets includes a pouch that encloses the stack of film sheets, and a leader that is positioned over a face of the pouch and is secured to a leading edge of the pouch so that the leader remains over the ouch until an operator pulls it away from the pouch and feeds it into a spindle to remove the package from the stack of film sheets.

Abstract: A package for a stack of X-ray film sheets has a pouch and a leader secured to the pouch. Heat seals secure side edge portions of the leader to edges of outer faces of sheets forming the pouch. Rows of perforations and slits in the leader adjacent the heat seals enables tearing of the leader from the pouch edges.

Abstract: A package for a stack of film sheets has a pouch that is sealed around the stack of sheets and a leader that is secured to the pouch and engageable with a spindle in a magazine so that rotation of the spindle can pull the pouch from around the stack of sheets. The pouch and leader are formed of different polyolefin materials with the pouch comprising a material having a low coefficient of friction to enable the pouch to be easily pulled around the stack of sheets while the leader comprises a material having a high coefficient of friction to facilitate engagement with the spindle and pulling the pouch uniformly.

Abstract: A package has a light tight pouch that encloses a stack of rectangular sheets of film. The package can be loaded in either of two different kinds of equipment which have means for removing the pouch from the film stack so that the sheets can be fed seriatim from the stack. One kind of equipment requires the package to be oriented so that the pouch can be removed from a narrow side of the package while the second kind of equipment requires the package to be loaded therein so that the pouch can be removed from a long side of the stack of film. The pouch has flaps extending from one long side and one narrow side of the package, and the flaps are engageable by the pouch removing mechanism in the different kinds of equipment.

Abstract: A carrier for a package containing a stack of sheets of x-ray film has a first wall located along one side of the stack of sheets and a second wall located along the opposite side of the stack of sheets. The dimensions of the walls relative to the film sheets is such that the first wall extends less than the full width of the sheets and the second wall extends less than the full length of the sheets. This enables a sheet removing device to engage and remove a sheet from either side of the stack of sheets. The package can be loaded in either of two kinds of equipment which require the package to be oriented in different ways when sheets are to be fed from the stack.
