A web material dispenser includes a housing and a pivotable roll support assembly provided therein. A first mandrel is provided at a first attachment location of the roll support assembly to support a first roll of web material. A second mandrel is provided at a second location of the roll support assembly to support a second roll of web material. The web material dispenser permits one-handed operation to replace the rolls of web material and to change positions of the mandrels within the dispenser. The roll support assembly may have a linkage arm and/or a roll support arm. Positions of the first and second mandrels relative to the dispenser's opening can be switched by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. A method for switching positions of rolls in the web material dispenser is also provided.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.

Provided is a glass roll (1), including: a winding core (2); a film body (F), which is taken up into a roll shape by the winding core (2), and includes a glass film (3) and a scattering prevention film (7) having a smaller width than the glass film (3); and flanges (8) which are mounted to the winding core (2), and which are arranged on both sides of the film body (F) in a width direction. The film body (F) includes a detachable displacement prevention film (6) on a termination end portion side of the glass film (3) in a take-up direction. The displacement prevention film (6) includes a wide portion (6a) having a lager width than the glass film (3).

To carry out accurate defect inspection over a wide area, a defect inspection device includes: a radiation source section configured to emit an electromagnetic wave to a separator roll; and a sensor section configured to detect the electromagnetic wave that the radiation source section has emitted to the separator roll, the sensor section being configured to detect the electromagnetic wave before and after the separator roll is moved relative to the radiation source section.

Disclosed is a coreless roll of a tissue paper product made of a spirally wound continuous web having a first end and second end and an outer diameter in the range of 95 to 150 mm, the web of tissue paper product being wound to define an inner hole centrally positioned relative to the coreless roll such that the first end is located on the outer side of the coreless roll and the second end is located at the inner hole, a diameter of the inner hole being 20 to 50 mm, a density of the coreless roll being 80 to 150 kg/m.sup.3, and a caliper ratio of the roll being 10% to 80%, the tissue paper product including between two and four ply-bonded plies, at least one ply being Conventional Wet Press, and at least one ply being a structured ply.
