will cause the side members to pivot about the transverse center line 43 in fig2 4 5 and 6 of the base defining a hinge for the side members 26 27 36 and 37 the cover members 31 and 32 move from a spaced position toward the inclined top members 14 of the magazine 10 when the sheet 20 is finally removed from the cartridge the free end of the next successive sheet is also removed at this point the greater amount of dispensing force has been exerted the stack of sheets thereafter will fall back to its original position against the base 22 of the cartridge the force required to peel the sheets apart where adhered along an edge to separate the dispensed sheet 20 from the free end of the next successive sheet is less than the dispensing force and will not exceed the combined weight of the stack and the resilience of the material of the cartridge which serve to clamp said next sheet between the edges defining the exit opening the next successive sheet is now clamped at the exit opening as the cartridge has closed the exit opening upon this sheet this is illustrated in fig5 as the sheets are successively dispensed from a cartridge the stack of sheets is depleted and if the sheets were all to fall back upon the stack it may be such that the height of the side members 36 and 37 exceeds the dimension of the sheet material such that the free edge of the next sheet to be dispensed would fall back into the cartridge fig6 illustrates the position of the sheets after dispensing one sheet the stiffness of the sheets and the.
