Apparatus and a production process for producing rolls of disposable pieces of hygienic paper

A process for producing rolls of disposable pieces of hygienic paper comprising the stages of:

• (a) providing hygienic paper with a surface and thickness, width, and length dimensions, for producing rolls of disposable pieces of hygienic paper with predetermined width, and length dimensions of said pieces of hygienic paper;
• (b) cutting a first perforated lateral line on said hygienic paper, wherein said perforated lateral line includes at least two lateral perforations and at least one lateral space, wherein said lateral space is shorter than one of said lateral perforations;
• (c) cutting a second perforated lateral line on said hygienic paper, wherein said perforated lateral line includes at least two lateral perforations and at least one lateral space, wherein each of said lateral space of said second perforated lateral line is shorter than one of said lateral perforations of said second perforated lateral line, wherein each of said lateral space of said first perforated lateral line is facing one of said lateral perforations of said second perforated lateral line;
• (d) cutting additional perforated lateral lines, wherein there is a longitudinal distance between each of every two neighboring even-numbered perforated lateral lines and between each of every two neighboring odd-numbered perforated lateral lines, and wherein said longitudinal distance determines length dimensions of said disposable pieces of hygienic paper.

A roll of disposable pieces of hygienic paper from which disposable pieces of hygienic paper can be removed with one hand without any need for tearing or cutting said hygienic paper comprising:

• (a) an inner tube of a rigid material with a symmetry axis and external radius and height dimensions such that the section of the inner tube perpendicular to said symmetry axis is substantially round for the entire said height;
• and
• (b) at least two osable pieces of hygienic paper with a surface and thickness, and has a rectangular shape with width and length dimensions, and with two long edges and two short edges, deployed so as to synchronously rotate said roll of disposable pieces of hygienic paper when one of said disposable pieces of hygienic paper is removed, with said disposable pieces of hygienic paper packed onto said inner tube and onto themselves such that:
• (i) each of said disposable pieces of hygienic paper has a cylindrical shape, with a spiral section around the symmetry axis of the inner tube;
• (ii) all of said disposable pieces of hygienic paper are substantially packed to be fully overlapping in said width dimension of each piece;
• and
• (iii) each of said disposable pieces of hygienic paper is substantially packed to be partially overlapping in its length dimension with regard to each adjacent said disposable pieces of hygienic paper that it is in contact with, wherein one of said short edges of each of said disposable pieces of hygienic paper is substantially in close proximity to said adjacent disposable pieces of hygienic paper.
