Abstract
Abstract A cartridge for containing sheets to be fed into a reprographic machine comprising a container having an opening and a support band wound from a feed reel to a take-up reel mounted on said container, and carrying thereon sheets spaced along and interwound with the band on the feed reel. The support band and a sheet positioned thereon is guided from the feed reel to the take-up reel along a predetermined path passing adjacent to the opening. Adjacent to the opening the sheet is separated from the band to guide it through the opening, whereby the sheet is fed out from the cartridge.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
285 words
A cartridge for containing and serially feeding fresh sheets and for recovering used sheets respectively to and from a reporgraphic machine having a fresh sheet entry member and a used sheet exit, the cartridge comprising: a container having means defining a first and a second chamber and means defining a corresponding opening for each chamber, means connected to said container for removably positionifng the cartridge in the reprographic machine with said first opening adjacent to said fresh sheet entry and said second opening adjacent to said used sheet exit, a feed reel in said first chamber, a take-up reel in said second chamber, a flexible support wound on said feed reel and having an end portion wound on said take-up reel, a plurality of fresh sheets disposed in regularly spaced positions on said support, and interwound with said support on said feed reel, first guiding means for guiding said support from said feed reel to said take-up reel along a predetermined path going out from said first chamber through said first opening and entering into said second chamber through said second opening, means connected to said reels and operable when the cartridge is positioned in the reprographic machine for advancing said flexible support and a fresh sheet positioned thereon from said feed reel along said path, means adjacent to said first opening for separating a fresh sheet advancing along said path from said flexible support to deflect it towards the fresh sheet entry, and second guiding means in said second chamber for guiding, during the advancing of said flexible support, a used sheet entering into said second chamber through said second opening to wind the used sheet with said flexible support on said take-up reel.
Claim 2
Dependent Claim
285 words
A cartridge for containing and serially feeding fresh sheets and for recovering used sheets respectively to and from a reporgraphic machine having a fresh sheet entry member and a used sheet exit, the cartridge comprising: a container having means defining a first and a second chamber and means defining a corresponding opening for each chamber, means connected to said container for removably positionifng the cartridge in the reprographic machine with said first opening adjacent to said fresh sheet entry and said second opening adjacent to said used sheet exit, a feed reel in said first chamber, a take-up reel in said second chamber, a flexible support wound on said feed reel and having an end portion wound on said take-up reel, a plurality of fresh sheets disposed in regularly spaced positions on said support, and interwound with said support on said feed reel, first guiding means for guiding said support from said feed reel to said take-up reel along a predetermined path going out from said first chamber through said first opening and entering into said second chamber through said second opening, means connected to said reels and operable when the cartridge is positioned in the reprographic machine for advancing said flexible support and a fresh sheet positioned thereon from said feed reel along said path, means adjacent to said first opening for separating a fresh sheet advancing along said path from said flexible support to deflect it towards the fresh sheet entry, and second guiding means in said second chamber for guiding, during the advancing of said flexible support, a used sheet entering into said second chamber through said second opening to wind the used sheet with said flexible support on said take-up reel.
Claim 3
Dependent Claim
271 words
A cartridge for containing and serially feeding fresh sheets and for receiving used sheets respectively to and from a reprographic machine having a fresh sheet entry and a used sheet exit, the cartridge comprising: a container having means defining a first opening and a second opening, means connected to said container for removably positioning the cartridge in the reprographic machine with said first opening adjacent the fresh sheet entry and the second opening adjacent the used sheet exit of the reprographic machine, a feed reel and a take up reel rotatable mounted on said container, a flexible support wound on said feed reel and having an end portion wound on said take up reel, a plurality of sheets spaced on said flexible support and interwound with the support on said feed reel, first guiding means for guiding said support from said feed reel to said take up reel along a predetermined path going out from said container through said first opening and entering into said container through said second opening, means connected to said take up reel and operable when the cartridge is positioned in the reprographic machine for advancing said flexible support and a fresh sheet positioned thereon from said feed reel along said path, means adjacent said first opening for separating a fresh sheet advancing along said path from said flexible support to deflect it towards the fresh sheet entry, and second guiding means for guiding, during the advancing of said flexible support, a used sheet coming out from the used sheet exit, through said second opening to wind it with said flexible support on said take up reel.
Claim 4
Dependent Claim
271 words
A cartridge for containing and serially feeding fresh sheets and for receiving used sheets respectively to and from a reprographic machine having a fresh sheet entry and a used sheet exit, the cartridge comprising: a container having means defining a first opening and a second opening, means connected to said container for removably positioning the cartridge in the reprographic machine with said first opening adjacent the fresh sheet entry and the second opening adjacent the used sheet exit of the reprographic machine, a feed reel and a take up reel rotatable mounted on said container, a flexible support wound on said feed reel and having an end portion wound on said take up reel, a plurality of sheets spaced on said flexible support and interwound with the support on said feed reel, first guiding means for guiding said support from said feed reel to said take up reel along a predetermined path going out from said container through said first opening and entering into said container through said second opening, means connected to said take up reel and operable when the cartridge is positioned in the reprographic machine for advancing said flexible support and a fresh sheet positioned thereon from said feed reel along said path, means adjacent said first opening for separating a fresh sheet advancing along said path from said flexible support to deflect it towards the fresh sheet entry, and second guiding means for guiding, during the advancing of said flexible support, a used sheet coming out from the used sheet exit, through said second opening to wind it with said flexible support on said take up reel.
Claim 5
Dependent Claim
79 words
A cartridge according to claim 2 in which said predetermined path comprises a first rectilinear segment between said feed reel and said first opening along which the support is advanced in a first advancing direction and wherein said means for separating includes means for defining in said predetermined path adjacent said first segment a second segment along which the support is advanced in a second advancing direction which forms with the first direction an angle substantially greater than 90°.
