Abstract

A rewinder comprising a first take-up roller (3) and a second take-up roller (5). A nip (11) is formed between the first take-up roller and the second take-up roller. The first take-up roller (3) comprises a first suction chamber (31) and a first pressure chamber (33). The second take-up roller (5) has a second suction chamber (45), which optionally has a second pressure chamber (43). The first take-up roller (3) and the second take-up roller (5) each have a perforated outer sheath in which the pressure chamber and the suction chamber of both the first take-up roller and the second take-up roller are fixedly provided. The pressure and suction inside the perforated outer sheath helps to start winding the new roll without the core.

Description

technical field [0001] The present invention relates to machines and methods for producing web rolls. Embodiments disclosed herein relate to rewinders for making rolls or tissue rolls, for making kitchen paper, toilet paper, and the like. More specifically, embodiments disclosed herein relate to machines and methods for making so-called coreless rolls or webs (ie, rolls that do not include a winding core). Background technique [0002] In some industrial fields, continuous webs are wound to form rolls of desired length and diameter. For example, in the paper converting industry, bulky master paper rolls are unwound and then rewound to form rolls or rolls of smaller diameter corresponding to the final diameter of the article for distribution to the final consumer . The axial length of these rolls corresponds to the width of the paper stock from the main paper roll, so that these rolls are cut into smaller rolls. Smaller volumes are packaged and then distributed to end use...
