    Abstract: A tissue log cutting saw has an arm movable orbitally within an interior of saw house. A spindle and housing is mounted to the arm. A tool holder with a blade is arrangeable at a first end of the spindle, and an opposite second end rotationally drives the spindle while providing access to an operator of a clamp in the spindle. The clamp is moveable between a hold position in which the clamp engages the tool holder at the first end, and a release position in which the clamp disengages from the tool holder and allows the tool holder to be removed from the first end. An actuator mounted to a structure separate from the arm has an end effector that cooperates with the operator of the clamp to enable the tool holder to be released from the clamp to facilitate automatic changing of a blade of the saw.

    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.

    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.
