Claims11
A sheet folder comprising input rollers, exit rollers and first and second fold boxes each comprising an inner and an outer fold plate which are each curved substantially along their whole length, wherein the outer curved fold plate of the second fold box comprises in the vicinity of its entrance an additional curved portion that is curved in a direction opposite to a curve of other portions of the second fold box to induce a sheet to curve in two opposite directions for assisting a smooth transition for the sheet as it enters the second fold box and encouraging the sheet edge to tuck into the second fold as it is flattened by the exit rollers.
A sheet folder comprising:
- a first curved fold box for making a first fold in a sheet;
- a second curved fold box for making a second fold in the sheet having an additional curved portion that is curved in a direction opposite to a curve of other portions of the second fold box to induce an “S” shaped curve in the sheet for assisting a smooth transition for the sheet as it enters the second curved fold box and encouraging a sheet edge to tuck into the second fold as it is flattened by exit rollers.
