The invention relates to a roll for use in a manufacture of a fibrous web, which comprises cellulosic fibers. The roll comprises a roll body with a cylindrical surface, and a roll cover, which is arranged to cover the cylindrical surface of the roll body. The cover has a functional layer, which has a polymer matrix and reinforcing material in the form of functional particles and/or functional fibers embedded in the polymer matrix. The functional particles and/or functional fibers has nanocellulose material. The invention relates also to the use of the roll.

A technical roll, in particular for paper manufacturing, having an elongated roll core and at least one first covering which is provided on the roll core, wherein an empty duct or conduit is provided, which is suitable for receiving a polymer fibre and extends over the length of the roll such that the polymer fibre can be introduced at one end of the empty duct. The application also relates to a technical roll having a polymer fibre, to a method for introducing the polymer fibre into an empty duct, and to the use of a polymer-based optical waveguide as a sensor in a technical roll.

The industrial roll according to the invention includes a core member made of a metal, a first adhesive layer formed in contact with an outer surface of the core member, a second adhesive layer formed on an outer surface side of the first adhesive layer, and a cover member formed in contact with an outer surface of the second adhesive layer and made of an elastic material. The first adhesive layer is made of a material with better adhesive properties to the core member than to the cover member, and the second adhesive layer is made of a material with better adhesive properties to the cover member than to the core member.

A fiber structure manufacturing apparatus that includes: a defibration unit that pulverizes and defibrates a raw sheet material that contains fibers; a transportation unit that transports a defibrated material after defibration by the defibration unit; a forming unit that forms a fiber structure from the defibrated material transported by the transportation unit; a temperature acquisition unit that acquires a temperature inside the defibration unit; and a control unit that controls a mass flow of gas that contains the defibrated material transported from the defibration unit in accordance with the temperature acquired by the temperature acquisition unit.

A smoking rolling paper and a method for rolling and packaging the same is provided. The smoking rolling paper is rolled into cylindrical shape and placed within an enveloping means. The smoking rolling paper is wrapped into cylindrical form causing the cigar tobacco paper to form a plurality of layers, wherein said layer comprises a double strip section. The rolled smoking rolling paper is then placed inside an enveloping means. The encased smoking rolling paper within the enveloping means allows for the smoking rolling paper to keep a cylindrical shape until delivered and used by a consumer. The enveloping means may maintain the moisture for longer time due to the rolling method prior to delivery to a consumer.

A press cover for a press roll or a transport belt has at least one polyurethane-containing layer. The polyurethane is obtainable by reaction of i) a polyol component, ii) an isocyanate component, and iii) a component containing at least one crosslinker. The polyol component is composed of mutually different structural units having the general formula —O—R.sup.1—X—R.sup.2—O— in which all of R.sup.1 and R.sup.2 independently of one another are identical or different and are linear or branched C.sub.1-C.sub.20 alkylene groups. Groups X are identical or different and are selected from bond, O, C(O)—O, and O—C(O)—O. At least 70 wt % of the structural units meet the following criteria: a) at least 80% of X are O—C(O)—O and the remainder are O or C(O)—O, and b) the average chain length of R.sup.1 and R.sup.2 is 8 or more carbon atoms, and c) at least 50% of R.sup.1 and R.sup.2 are independently of one another a linear or branched C.sub.8-C.sub.12 alkylene group.

The present invention relates to a paper substrate with smooth face that is suitable for being used in a filter for a smoking article or vaping article.

An apparatus for producing a web of fibrous material includes a roll having incisions with a depth of 0.01-2.00 mm, a width of 0.01-2.00 mm, and a pitch 0.01-10.00 mm, and rotated at a peripheral velocity v.sub.1 equal to the velocity of an upstream apparatus unit; a belt stretched between transmission rollers that advances at a velocity v.sub.2 less than v.sub.1, wherein v.sub.1/v.sub.2 lies between 1.05 and 1.40; a presser roller rotating at a peripheral velocity v.sub.2, associated with a presser system acting to press the belt against the metal roll with a pressure of 1-200 kg per centimeter; and a system that feeds a sheet of pliable fibrous material between the belt and the roll, the belt having a longitudinal elongation of no more than 5%, dimensional stability along its entire length, a thickness of 1-10 cm, and a hardness 24-70° Shore A.
