Abstract
A system and a method for creating a fold line in a substrate, by impressing at least one crease line onto the substrate. The impressing is carried out by compressing the substrate between a die and a corresponding counter die of a creasing module. Following impression of the crease line, at least one cut is made in the substrate along the crease line thereby to form the fold line. The at least one cut has a depth less than the thickness of the substrate at the crease line.
Claims91
A system for creating a fold line in a substrate, the system comprising:
- a creasing module including a die, a counter die, and a compression mechanism, said creasing module adapted to impress at least one crease line onto the substrate by compressing the substrate between said die and said counter die by means of said compression mechanism;
- and
- a cutting module adapted to make at least one cut in the substrate, said at least one cut having a depth less than a thickness of the substrate at said crease line, said crease line and said at least one cut being at least partially overlapping so as to form the fold line,
- wherein said depth of said at least one cut is in the range of 5% to 70% of said thickness of the substrate at said crease line.
The system of any one of the preceding claims, wherein said cutting module includes at least one mechanical cutter.
The system of any one of the preceding claims, further comprising:
- an input module adapted to align the substrate in a desired orientation and to feed the aligned substrate to the creasing module;
- and
- a conveyance mechanism adapted to convey the substrate to said creasing module while the substrate remains in said desired orientation.
The system of any one of the preceding claims, wherein a total length of said at least one cut is less than a length of said crease line.
The system of any one of the preceding claims, wherein a total length of said at least one cut is at most 75%, at most 60%, at most 50%, or at most 40% of a length of said crease line.
The system of any one of the preceding claims, wherein a total length of said at least one cut is within a range of 10%-75%, 10%-60%, 10%-50%, 20%-50%, 25%-50%, or 25%-40% of said length of said crease line.
The system of any one of the preceding claims, wherein said at least one cut comprises a single cut disposed at a center of said crease line.
The system of any one of the preceding claims, wherein said depth of said at least one cut is at least 10%, or at least 15% of said thickness of the substrate at said crease line.
The system of any one of the preceding claims, wherein said depth of said at least one cut is at most 60%, at most 50%, at most 40%, at most 30%, or at most 25% of said thickness of the substrate at said crease line.
The system of any one of the preceding claims, wherein a folding force of said fold line is in the range of 30%-65%, 30%-60%, 35%-60%, 40%-60%, 45%-60%, or 45%-55% of a folding force of said crease line prior to cutting thereof.
The system of any one of the preceding claims, wherein a variation of said depth of said at least one cut along said at least one cut is within 15%, within 10%, within 8%, or within 5% of said thickness of said substrate.
The system of any one of the preceding claims, wherein a variation of said depth of said at least one cut along said at least one cut is within 15%, within 10%, within 8%, or within 5% of said depth of said at least one cut.
The system of any one of the preceding claims, wherein said at least one cut is disposed at a center of a cross section of said crease line.
The system of any one of the preceding claims, wherein said at least one cut is disposed at a minimum point of a cross section of said crease line.
The system of any one of the preceding claims, wherein a bead of said crease line is visible along an entire length of said fold line.
The system of any one of the preceding claims, wherein the substrate comprises a fibrous substrate.
The system of any one of the preceding claims, wherein the substrate has a thickness greater than 450 μm, greater than 500 μm, greater than 550 μm, greater than 600 μm, or greater than 650 μm.
The system of claim 35, wherein said laminated fibrous substrate has a thickness less than 350 μm, less than 300 μm, less than 250 μm, or less than 200 μm.
A method for creating a fold line in a substrate, the method comprising:
- impressing a crease line onto the substrate by compressing the substrate between a die and a corresponding counter die of a creasing module;
- and
- making at least one cut in the substrate, said at least one cut having a depth less than the thickness of the substrate at said crease line,
- wherein said crease line and said at least one cut at least partially overlap so as to form the fold line,
- wherein said depth of said at least one cut is in the range of 5% to 70% of said thickness of the substrate at said crease line.
A three dimensional folded product comprising at least one substrate sheet folded along at least one fold line, at least one of at least one fold line including a crease line having at least one cut formed therealong, said at least one cut having a depth less than the thickness of said substrate sheet at said crease line, said depth being with the range of 5% to 70% of said thickness of said substrate sheet.
