The invention relates to a paper profile (1), in particular for a packaging element or packaging equipment of food packaging. The paper profile (1) has an elongated shape. The paper profile (1) is formed by at least one round or almost round, flexurally rigid paper rod (3) or a plurality of round or almost round, flexurally rigid solid paper rods (3). The flexural rigidity of the paper profile (1) corresponds in at least one bending direction to the flexural rigidity of one of the rigid paper rods (3).

The invention relates to paper processing, namely the processing of a paper web or a paper web section in order to form a paper stick. The processing is carried out in multiple process stages, including storing the paper web, stretching the paper web, controlling/regulating the guide for the lateral edge, conveying the paper web, folding the paper web, rolling, adding an additive, cutting, removing the remaining paper web, separating the paper sticks, drying the sticks, and/or post-treating the sticks.

A machine (1) for producing drink stirring sticks (105) made of paper material comprising a feeding device (10) for feeding a web or sheet made of paper material (100) along a predetermined feeding direction (110). The machine (1) comprises a separation unit (200) for separating a plurality of curved elongated portions (105) from the web or sheet. The separation unit (200) comprises a folding device (40) configured to fold the web or sheet in such a way to separate the curved elongated portions (105) from the web or sheet. The folding device (40) is equipped with a first folding member (41) provided with at least one protruding portion (43) and a second folding member (42) provided with at least one recessed portion (44) having a shape which is complementary to the or each protruding portion (43) and arranged to be positioned adjacent to respective sides (101,102) of said web or sheet to apply a folding action on said web or sheet at a folding zone (45).

A paper product that includes an article of paper, a binding agent disposed on a surface of the article of paper, and an animal-affecting substance. The animal-affecting substance is bound to the strip of paper via the binding agent and the paper is in a twisted cord configuration such that the animal-affecting substance is disposed within an interior defined by the article of paper.
