    Abstract: A method of cleaning a blade of a log saw of a converting line comprises applying a cleaning agent to a saw blade. The saw blade is adapted to cut a log of web material into rolls as the log of web material advances on a conveyor. In an another step of the method the log is advanced on the conveyor for cutting with the saw blade. In another step of the method, the saw blade is cleaned by cutting the log with the saw blade with the cleaning agent applied to the saw blade.

    Abstract: Elongated product is cut while the product moves longitudinally by a cutting blade which passes through the product and which also moves longitudinally with the product. The product is supported by first and second product supports which are spaced apart in the longitudinal direction to provide a gap through which the cutting blade passes. The product supports are mounted for movement in the longitudinal direction and move longitudinally as the cutting blade passes through the gap.

    Abstract: A control system is provided for a converting line. The converting line has an unwinder for unwinding web material from a roll of web material and at least one independently driven roll for directing the web material unwound from the unwinder to the converting line. The control system has a controller and a tension sensor configured to be arranged downstream of the at least one driven roll. The tension sensor is configured to sense a tension in the web as the web is passed downstream of the driven roll, generate a signal indicative of sensed web tension, and transmit the signal of sensed web tension to the controller. The controller is configured to a generate and transmit to the unwinder a signal to change the speed of the unwinder based upon the tension sensed by the tension sensor.

    Abstract: An apparatus supports a convolutely wound log of web material during cutting of the convolutely wound log, and includes a bottom support link operatively pivotally coupled to a support frame and a side support link operatively pivotally coupled to the support frame and the bottom support link. A flexible member operatively coupled to a distal end of the side support link extends tangentially from the side support link and curves away from the side support link and the bottom support link so that a portion of the flexible member is spaced away from the side support link and the bottom support link. The spaced away portion of the flexible member together with the side support link and the bottom support link at least in part define a support surface for supporting the convolutely wound log when the log is directed into the apparatus.

    Abstract: A control system for a converting line has a sensor configured to sense a distance between the sensor and a surface of a roll of web material as the roll of web material is unwound from an unwinder and directed to the converting line. The controller is configured to: (i) determine a diameter measurement of the roll as the roll rotates based upon the sensor signals; (ii) store a plurality of data structures in a memory of a controller of a control system wherein the data structures comprise a plurality of data items associated together as the diameter measurements of the roll of the web material; (iii) process by a statistical regression analysis the data structures associated with the diameter; and (iv) generate signals for controlling the converting line based upon the processed diameter measurements.
