1. An apparatus for manufacturing a plurality of sheets by stacking and feeding the sheets, comprising:
- a supply unit for supplying stacked sheets;
a turning unit for turning the stacked sheets in a plane thereof;
an inverting unit for vertically inverting the stacked sheets;
a discharge unit for discharging the stacked sheets; and
a transfer unit for transferring the stacked sheets to said turning unit, said inverting unit, or said discharge unit.

Abstract
Sheets held by a sheet transfer mechanism are supplied from a supply unit to an aligning unit, and aligned with each other by the aligning unit. Thereafter, corners of the sheets are cut off by first and second cutting units, and then the sheets are vertically inverted by an inverting unit. Then, the sheets are turned into a given direction by a turning unit, and supplied to a discharge unit, from which the sheets are discharged.

5. A method of manufacturing a plurality of stacked sheets by feeding the sheets, comprising the steps of:
-
holding a first presser member in abutment against a central portion of an upper surface of stacked sheets;
pressing a support member having a concave support surface against a lower surface of said stacked sheets;
holding the upper surface of stacked sheets with a second presser member adjusted depending on the thickness of said stacked sheets; and
sandwiching and feeding said stacked sheets with said first presser member, said support member, and said second presser member.

6. An apparatus for manufacturing a plurality of stacked sheets by feeding the sheets, comprising:
-
a first presser member for being held in abutment against a central portion of an upper surface of stacked sheets;
a support member having a concave support surface for supporting a lower surface of said stacked sheets; and
a second presser member for holding the upper surface of stacked sheets, said second presser member being adjustable depending on the thickness of said stacked sheets;
the arrangement being such that said stacked sheets are curved by said first presser member said support member, and sandwiched and fed by said second presser member and said support member. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of manufacturing a plurality of stacked sheets by cutting off corners thereof, comprising the steps of:
-
positioning stacked sheets by holding two substantially perpendicular sides of the sheets in abutment against respective two limiting guides which are disposed in association with said two substantially perpendicular sides of the sheets;
cutting off corners of the sheets opposite to corners thereof between said two substantially perpendicular sides while the stacked sheets are being limited by said limiting guides; and
repeating said positioning and cutting steps on each of the corners of said stacked sheets.

13. An apparatus for manufacturing a plurality of stacked sheets by cutting off corners thereof, comprising:
-
first, second, third, and fourth cutting units for cutting respective four corners of stacked sheets; and
a feed mechanism for feeding the stacked sheets between said first, second, third, and fourth cutting units;
each of said first, second, third, and fourth cutting units comprising;
two limiting guides disposed in association with two substantially perpendicular sides of the stacked sheets; and
a cutting mechanism for cutting off corners of the sheets opposite to corners thereof between said two substantially perpendicular sides. - View Dependent Claims (14, 15, 16)
