Abstract
A method for handling a material sheet in a sheet-wise booklet making system, including the steps of advancing a sheet to a movable clamping drive at a first position, clamping the sheet in the clamping drive at the first position, moving the clamping drive in a non-linear path to a second position, establishing a fold in the sheet with a folding device, moving the clamping drive in a non-linear path to a third position, and delivering the folded sheet to a collecting device, such that a leading side and a trailing side of the folded sheet are respectively delivered to a frontside and a backside of the collecting device.

A method for handling a material sheet in a sheet-wise booklet making system, comprising the steps of:
- advancing a sheet to a movable clamping drive at a first position;
- clamping the sheet in the clamping drive at the first position;
- moving the clamping drive in a non-linear path to a second position;
- establishing a fold in the sheet with a folding device;
- moving the clamping drive in the non-linear path to a third position;
- delivering the folded sheet to a collecting device by rotating the clamping drive to independently advance the sheet, wherein a leading side and a trailing side of the folded sheet are respectively delivered to a frontside and a backside of the collecting device;
- and
- reciprocating the clamping drive to the first position along the non-linear path in a reverse direction.
An apparatus for handling sheet material, comprising:
- a main drive for advancing sheet material;
- a saddle for collecting sheet material;
- a rotatable arm and a clamping drive, wherein the clamping drive includes a drive tire and a foot, the drive tire and the foot operative to clamp sheet material and wherein the rotatable arm operates to move the clamping drive about an axis from the main drive to the saddle;
- and
- a folding device for establishing a fold in sheet material while sheet material is clamped by the drive system.
A method for handling a material sheet comprising the steps of:
- clamping the sheet using a movable clamping drive;
- establishing a fold in the sheet;
- moving the clamping drive along a non-linear path in a first direction to deliver the sheet to a collecting device, such that a leading side and a trailing side of the sheet are respectively delivered to a frontside and a backside of the collecting device;
- and
- reciprocating the clamping drive along the non-linear path in a second direction.
