A device for rolling a sheet includes a main casing which extends between a front face and a rear face and includes a cap which includes a first receiving slot, a sliding element translationally movably mounted in the main casing, from the front face of the casing and including a shell including a second receiving slot, a rotary element rotatably movably mounted and including a shaft housed inside the main casing, from the rear face of the casing, the shaft including an open third receiving slot, and a stop surface. In the closed position of the rolling device, the first and second slots are aligned along the same vertical plane.

Apparatus (10) for automatically producing tubular elements (100) to make smoking articles and/or products for food use, comprising at least one forming unit (12) configured to form the tubular elements (100) starting from shaped flat sheets (101). The forming unit (12) comprises one or more forming devices (29) which are moved by movement means (30) along a work path (PL) closed in a loop, in order to form the tubular elements (100).

The invention relates to a method of making a paper product 10, 10.01 to 10.14, wherein the method includes the step of adding natural reinforcing material (31, 31.1, 51, 51.1, 61, 61.1, 71, 71.1) to one of: a) a layer of pulp as it exits or after it exits from a layer formation process or apparatus; or b) a tank 20, 20.1, 20.2 of pulp prior to it exiting from a layer formation process or apparatus; or c) a combination of a) and b). Additionally, the invention relates to paper products made by this process. The present invention also provides a multi-layered material 2.10, 2.10, 2.10.1, 2.100 to 2.1600, and 100 to 1900, and a layer treatment of a layer or layers of a multilayered material, and a multilayered material which has had such a layer or layers treated by such a layer treatment.
