MACHINE FOR MANUFACTURING CONTINUOUS TOILET SEAT COVER REELS
20210197514 · 2021-07-01 ·

The present disclosure relates a machine for manufacturing continuous toilet seat cover reels. In certain embodiments, the machine includes: a continuous paper reel transmission mechanism, a modular cutting mechanism, and a counting wheel. The continuous paper reel transmission mechanism receives continuous paper from a continuous paper reel on a continuous paper reel rotating shaft. The modular cutting mechanism with a modular cutting wheel receives continuous paper reel from the continuous paper reel transmission mechanism and perforates the continuous paper reel using the modular cutting wheel to generate a continuous toilet seat cover. The counting wheel counts the number of toilet seat cover sheets on the continuous toilet seat cover generated. When the number of toilet seat cover sheets generated reaches a predetermined number, continuous toilet seat cover reel output device cuts last toilet seat cover sheet from the continuous toilet seat cover to produce the continuous toilet seat cover reel.

Methods include: loading a continuous paper roll onto a shaft in a first end of the machine; threading continuous paper on continuous paper roll through a continuous paper reel transmission mechanism, a printing wheel, a modular cutting mechanism, a counting wheel of the machine, onto a reel at a continuous toilet seat cover reel output device in a second end; perforating continuous paper roll to form sheet perforated tear lines, a splash prevention perforated tear line, one or more vertical splash prevention perforated tear lines and horizontal splash prevention perforated tear lines; counting the number of toilet seat cover sheets generated on the continuous toilet seat cover; and cutting the last sheet of toilet seat cover sheet from the continuous toilet seat cover to produce the continuous toilet seat cover reel.

Tooling method for expanded slit sheet material
11034120 · 2021-06-15 ·

The present invention discloses a method of producing at least a pair of interlocking adjacent layers of a paper packaging product, the pair of interlocking adjacent layers being formed of a sheet of slit paper having a slit pattern, the slit pattern upon expansion, forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet. The method comprises slitting the sheet of slit paper with beveled blades that have a first wedge angle on one side of the blades and a second wedge angle on the other side of the blades, wherein the first wedge angle is wider than the second wedge angle to produce slits that upon expansion, produce the lands regions that have angles of inclination in a range for 50 to 85 degrees.

EXPANDABLE SLIT-SHEET STOCK MATERIAL, DUNNAGE CONVERSION SYSTEM AND METHOD FOR EXPANDING
20210101356 · 2021-04-08 ·

An improved expandable slit-sheet stock material is configured to aid in temporarily restricting opening of a plurality of slits of the slit-sheet stock material, such as during winding of the unexpanded stock material or during expansion of the stock material. Each slit of the plurality of slits includes one or more un-slit reinforcement portions, such as reinforcement ties, extending fully between opposite longitudinal sides of the slit, and disposed between opposed transverse endpoints of the slit. The reinforcement ties minimize or prevent tearing of the stock material during the winding or expansion. A dunnage conversion system for expanding the slit-sheet stock material includes an expander having a pair of opposed rollers. The rollers engage the stock material to effect breaking of the un-slit reinforcement portions and expansion of the slit-sheet stock material.
