  • Patent number: 6617007
    Abstract: A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

  • Patent number: 5632849
    Abstract: The winding system includes several rollers and a rotating drum, around which the web winds before being wound on a core. A cutting and tabbing assembly cuts the web against the rotating drum and cuts and applies the tab on the web in registration with the cut end of the web. The cutting and tabbing assembly includes a wheel, a knife mounted on the wheel, and a tab bar mounted on the wheel adjacent the knife. During the winding of the web on the core the proper amount of tab paper is unwound and moved toward the knife to cut and grab the tab. Then, the knife and tab bar rotate to cut the web while the tab bar applies the tab onto the cut end of the web.
