摘要： A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.

摘要： A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

摘要： Rewinder for producing paper logs, comprising a winding station with a first winding roller, a second winding roller and a third winding roller driven by corresponding electric motors, including a detection system capable to detect a succession of diameters of the log being formed in the winding station and a programmable electronic unit connected to the electric motors. The system compares the measured diameters with a succession of corresponding diameters of predetermined value and to calculate a sequence of differences between these values. The electronic unit determines a parameter (a) related to the trend over time of the values. The electronic unit changes the relative speed of the first and second roll depending on the value of the parameter.

摘要： The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

摘要： A cam-controlled core inserter for a surface winder is disclosed. The cam-controlled core insertion device provides for a shaft having a plurality of cam housings disposed thereabout. A cam cooperatively associated with a respective cam housing is disposed within a first surface of each of the cam housings. A fixed finger plate cooperatively associated with a respective cam housing and having a fixed finger fixably attached thereto is juxtaposed proximate to each of the cam housings and fixably attached to the shaft. A cam follower having a finger shaft that has a movable finger attached thereto is cooperatively associated with each of the cams. The distal end of each of the movable fingers and the distal end of each of the fixed fingers are capable of forming a space therebetween for contacting engagement and containment of a core suitable for the convolute disposal of a web material thereabout.
