Embodiment Construction

[0059] [59] Figures 1 and 2 schematically show a winding machine according to a first embodiment of the invention at two different moments in a winding cycle. In this case, the winder is used to produce coreless web.

[0060] [60] The arrangement of this winder (as far as the winding parts are concerned) is substantially the same as that of US Patent n. 5,639,046, to which reference is made for a more detailed description of the structural features and operation of this type of winder.

[0061] [61] Figures 1 and 2 show the main components of the winder. The winding machine, generally indicated by the numeral 1 , comprises a first winding roll 3 , a second winding roll 5 and a third winding roll 7 . These three winding rollers together form a winding frame in which a long roll L is formed. The long roll L formed by the winder is then cut transversely to its axis into single rolls or shorter rolls of axial length corresponding to the length of the final product.

Abstract

A rewinder machine for the production of rolls of web material is described, comprising: a winder unit (3, 5, 7); a path for delivering the web material (N) to said winder unit; a system for continuously feeding said web material into said winder unit; a distributor (31) of a sheet material (F) for wrapping the rolls formed by said winder unit, installed and operated so as to deliver a length of sheet material to said winder unit on completion of the winding of each roll without stopping the forward feed of the web material.

Description

technical field [0001] [01] The present invention relates to improvements in methods and apparatus for producing rolls of web material, typically but not exclusively rolls of paper, especially toilet paper. [0002] [02] More particularly, the present invention relates to rewinders, especially of the circumferential or surface winding type, for the manufacture of rolls of toilet paper, kitchen paper or other sanitary paper, and related manufacture and winding method. Background technique [0003] [03] A machine called a winder is commonly used in the manufacture of toilet paper rolls, kitchen paper rolls or other such roll products. In these machines, a winding unit is fed and provided with a continuous web along a path. The rolls of mesh are wound sequentially in the winding unit, with or without winding cores or mandrels. Winding systems can be of the central or peripheral type, or even a combination of both. In the former case, the winding motion is provided by a cent...
