Embodiment Construction

[0064] Figure 1 to Figure 5 Shows an embodiment of a continuous peripheral rewinder according to the invention and in particular shows the sequence of operations of the conversion step, i.e. the step of discharging a bobbin whose winding has been completed and inserting a new winding core to start the formation of a subsequent bobbin .

[0065] Figures 1 to 5 The main elements of the rewinding machine are shown, limited to those necessary to understand the concept on which the invention is based and the mode of operation of the machine. Structural details, auxiliary units and other components which are known and / or can be designed according to the prior art are not shown in the figures or described in more detail. Other components can be provided by those skilled in the art based on their experience and knowledge in the field of paper converting machinery.

[0066] In short, in the embodiment shown here, the machine, generally designated 2 , comprises a first winding roll ...

Abstract

A rewinding machine comprising a first winding support formed between a first winding roll (1), a second winding roll (3) and a third winding roll (7). The first winding roll and the second winding roll define a nip (5) through which the winding core (A) with the web material (N) being wound around them passes. The rewinder also includes a feed path for the winding cores, which passes between the first winding roll (1) and the third winding roll (7). The second winding stand is formed between the first winding roller (1), the second winding roller (3) and the fourth winding roller (8). The rewinder also comprises a rolling surface (19) extending around the first winding roll (1) and defining a feed channel (21) for the winding core.

Description

technical field [0001] The present invention relates to a method and a machine for producing rolls of web material, in particular but not limited to rolls of paper, especially tissue paper, such as rolls of toilet paper, kitchen towels and the like. Background technique [0002] In the field of papermaking, especially for the production of rolls of toilet paper, kitchen towels, etc., large reels (parent reels) of tissue paper coming directly from continuous production machines are wound. These large spools are then unrolled and rewound to produce spools or bobbins with a smaller diameter corresponding to the diameter of the final product intended to be sold on the market. These rolls have an axial length equal to a multiple of the finished reel intended for distribution and sale, and are subsequently cut by a cutting machine to obtain the final product intended for packaging and subsequent sale. [0003] For the production of reels of web material, modern rewinders are prep...
