TH2402B - Coreless toilet paper rolls and the manufacturing process of such rolls? - Google Patents

Abstract

This invention deals with toilet paper rolls and the process of producing such rolls. The toilet paper roll in this invention does not have a central core, however, there is a hole in the middle for inserting the rod. A roll of paper that swivels and holds the paper in the toilet paper holder.

Claims (10)

1. A coreless toilet paper roll with a hole in the center that allows the rod of a toilet paper holder to be inserted, holding and hanging the roll in the holder. The hole in the center has a polygonal cross-section shape consisting of folded edges forming a star shape, with the part between the edges pushed inward in a curved manner into the hole. 2. A coreless toilet paper roll as described in claim 1, where the creases in the center hole of the roll are very sharp and the inward curve is in contact with the adjacent curve. 3. A coreless toilet paper roll as described in claim 1, where the creases in the center hole of the roll are relatively rounded and the inward curvature is separated from the adjacent curvatures by a relatively rounded crease. 4. The process for producing coreless toilet paper rolls with a central hole involves winding a sheet of toilet paper onto a winding shaft of a paper winding machine. This machine consists of a shaft with a cross-shaped, polygonal, or gear-like structure. The toilet paper is wound onto this shaft while it rotates, creating a rolled roll. The shaft is then pulled back, creating a hole in the center of the roll. The portion of the rolled paper above the shaft, between the angles of the polygonal shaft or between the teeth of the gear-like shaft, is slightly bent inward due to centrifugal pressure, resulting in a strong (non-collapsible) hole with a fixed shape. 5. A process for manufacturing coreless toilet paper rolls as described in Claim 4, whereby during the rolling process rollers press down on the rolling paper with constant pressure or with pressure that gradually decreases as the thickness of the rolling paper increases. 6. The process for manufacturing toilet paper rolls as described in Claim 4 or 5, where the angles of the polygonal roll shaft or the teeth of the gear shaft are parallel to the axis of the roll shaft. 7. The process for manufacturing toilet paper rolls as described in claim 4 or 5, where the angles of the polygonal reel shaft or the teeth of the gear reel shaft are arranged in a spiral around the reel shaft, and at the end of the toilet paper roll, the reel shaft is withdrawn from the roll by rotating the shaft as it is withdrawn. 8. A process for manufacturing coreless toilet paper rolls as described in claims 4 or 5, whereby when the toilet paper is rolled on such a roll, it is pre-moistened at the beginning of the rolling process using water or an aqueous solution containing adhesive or paper conditioner. 9. A process for manufacturing coreless toilet paper rolls as described in Claim 6, whereby when the toilet paper is rolled on a shaft, the paper is pre-moistened at the beginning of the rolling process using water or an aqueous solution containing adhesive or paper conditioner. 10. A process for producing coreless toilet paper rolls as described in Claim 7, whereby when the toilet paper is rolled on a shaft, the paper is pre-moistened at the beginning of the rolling process using water or an aqueous solution containing an adhesive or paper conditioner.
