  • Patent number: 4189077
    Abstract: In a cabinet for manually dispensing sheet material from a roll rotatably mounted within the housing of the cabinet, a combination of a blade having a cutting edge and movable from a first position to a second position relative to the housing when the sheet material is manually pulled against the cutting edge to sever a portion of the sheet material from the remainder of the roll, and sheet delivery means in operative association with the remainder of the sheet material and responsive to movement of the blade from the first position to the second position to deliver the free end of the remainder of the sheet material to a position facilitating manual grasping thereof by the user.

  • Patent number: 4106684
    Abstract: A dispensing device for sequentially dispensing sheet material such as paper toweling from a primary roll and a reserve roll, the primary roll initially being rotatably mounted at a first location and adapted to be displaced therefrom to a second location. Sheet material feed means is provided for dispensing the sheet material from the device. Sensing means is provided for sensing displacement of the primary roll from the first location and transfer means is employed in operative association with the sensing means and responsive to the sensing of the displacement of the primary roll from the first location to place sheet material from the reserve roll into operative engagement with the sheet material feed means.

  • Patent number: 4026752
    Abstract: Method of and apparatus for securing the tail or outer terminal convolution of a toilet tissue cant or similar roll product to the convolution immediately subjacent the tail. The tail of the roll product is secured by means of adhesive, and the method includes the step of ejecting a predetermined quantity of adhesive directly onto the subjacent convolution of the roll product while the tail is unwound therefrom. The adhesive is distributed along the length of the cant at spaced apart locations adapted to underlie the rewound tail, thereby allowing the tail to be adhesively secured to the cant. The apparatus includes adhesive applicator structure comprising a plurality of modules each of which is releasably secured to the apparatus so that it can be removed therefrom and replaced as an integer; and each adhesive applicator module includes a plurality of dispensing nozzles operative to eject a measured quantity of adhesive onto a cant underlying the same.

  • Patent number: 4000242
    Abstract: A system for treating paper webs and the like including a platen roller and a plurality of support rollers angularly spaced thereabout. At least one of the support rollers is an embossing roller cooperative with the platen roller to emboss a web advanced between the facing juxtaposed surfaces of the platen and embossing rollers. The platen roller is floatingly confined by the support rollers and has no rigidly fixed axis of rotation. Such platen roller is also hollow, including a cylindrical wall component defining a gaseous fluid pressurized chamber. The cylindrical wall component of the roller is of resilient construction and is inwardly depressible by the support rollers against the force of the gaseous pressure fluid acting outwardly thereagainst within the pressurized chamber. The web material to be treated is passed through the nips defined by one or more support rollers, including at least one embossment roller, and the platen roller.

  • Patent number: 3960272
    Abstract: Method of and apparatus for securing the unaffixed tail portion of a roll product to a convolution thereof underlying said tail portion wherein the completed roll product is provided with a manually graspable fold on the tail portion which is releasably secured to the underlying roll product convolution as by means of adhesive. Apparatus structure and method steps are provided whereby the tail portion of the roll product is positioned so that the free end thereof is spaced from a wound portion of the roll product. A fold is then provided in the roll product tail portion and a quantity of adhesive is applied to the roll product at a predetermined location thereon. The tail portion is then wound about the roll product wound portion and the fold is secured to the roll product convolution underlying same with said adhesive. A completed roll product is thus formed comprising an elongated sheet of flexible material wound to provide a plurality of convolutions including the outer tail portion convolution.
