Abstract
A sheet having two opposing sides and a fiber orientation, comprising: a first section on one side of the sheet; and a second section on another the other side of the sheet and substantially parallel to the first section, wherein the sections are not transverse to the fiber orientation of the sheet, and wherein the sections are dimensioned and arranged so that respective separation lines and separation regions formed on the respective sides of the sheet when the sheet is torn result in a homogeneous outlook where respective separation regions are hidden from view.
Claims20
A sheet having two opposing sides and a prominent fiber orientation, comprising:
- a first section on one side of the sheet;
- and
- a second section on another the other side of the sheet and substantially parallel to the first section,
- wherein the sections are not transverse to the prominent fiber orientation of the sheet, and
- wherein the sections are dimensioned and arranged so that respective separation lines and separation regions formed on the respective sides of the sheet when the sheet is torn result in a homogeneous outlook where respective separation regions are hidden from view.
A method for automatic processing of sheets, to make the sheets manually detachable with a hidden detachment line, the method comprising:
- (a) automatically feeding multiple sheets, in a single file, to a slitting unit;
- (b) forming, using at least one blade of said slitting unit, at least one elongated slit in each sheet of said multiple sheets, while said sheet is in motion through said slitting unit;
- (c) flipping said multiple sheets over to their opposite side and repeating steps (a) and (b), so as to provide at least one pair of elongated, parallel, adjacent slits in both sides of each sheet of said multiple sheets.
A method for processing a sheet, the method comprising:
- executing a first elongated slit on a first side of said sheet and a second elongated slit on a second side of said sheet, wherein said first and second elongated slits are parallel and adjacent, such that, when said sheet is torn, a torn region of said sheet remains hidden in a top view.
