Abstract
A sheet material trimming apparatus and method are described which are suitable for use in a booklet making system. An exemplary apparatus includes at least one cutter for trimming a first and a second edge of a sheet material in a first and a second direction, and a drive system for moving the sheet material in two perpendicular directions for trimming the first and second edges with the at least one cutter. The drive system moves the sheet material in two perpendicular directions by rotating and translating a roller. The sheet material trimming apparatus allows for automatic changes in the amount of material cut off each side of the sheet material by moving the sheet material in two directions without requiring repositioning of the cutter(s).
Claims26
A sheet material trimming apparatus, comprising:
- a first cutter arranged to trim an edge of a sheet material in a first direction;
- a second cutter arranged to trim an edge of the sheet material in a second direction different from the first direction;
- and
- a drive system having a drive roller for advancing the sheet material in the first direction by rotation of the drive roller and for translating the sheet material in the second direction by translation of the drive roller.
An apparatus for trimming sheet material, comprising:
- cutting means for trimming a first edge and a second edge of a sheet material in a first direction and a second direction;
- and
- drive means for moving the sheet material in two perpendicular directions for trimming the first and second edges with the cutting means, the drive means moving the sheet material in two perpendicular directions by rotating and translating a roller.
A method for trimming sheet material comprising:
- feeding a sheet material into a trimming mechanism;
- advancing the sheet material in a first direction to a first trimming position by rotation of a drive roller;
- trimming a first side of the sheet material;
- translating the sheet material in a second direction to a second trimming position by translation of the drive roller;
- and
- trimming a second side of the sheet material.
A booklet making system for assembling plural sheets into a bound stack, comprising:
- a drive system for advancing sheet material in a first direction;
- and
- a sheet material trimming apparatus for receiving the sheet material advanced by the drive system, the sheet material trimming apparatus including a first cutter arranged to trim an edge of a sheet material in a first direction;
- a second cutter arranged to trim an edge of the sheet material in a second direction different from the first direction, and wherein the drive system is configured to translate the sheet material in a second direction by translation of the drive roller.
