Abstract: A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.

Abstract: An embossing roll has an embossing region that has a plurality of embossing elements. Each of the embossing elements projects outward from a surface of the embossing roll a distance of about 0.2 mm to about 2.0 mm. The plurality of embossing elements are arranged in the embossing region in a pattern. The plurality of embossing elements has at least a first set of embossing elements and a second set of embossing elements. The first set of embossing elements has a first shape and the second set of embossing elements has a second shape that is different from the first shape.

Abstract: A method includes a bag forming process with a bag wicketing machine having a sideweld seal head that receives plies of web material, conveys the plies through the sideweld seal head, seals the plies together, cuts the plies to form a bag blank, and moves the bag blank onto an exit conveyor. Pressurized air from nozzles of a pneumatic blow down bar is directed at the bag blank. With an energized laser operatively mounted on the pneumatic blow down bar, the position of the pneumatic blow down bar relative to the bag blank and the exit of the sideweld seal head is adjusted so that a beam emanating from the laser is positioned against the bag blank at a desired location where pressurized air from the nozzles of the pneumatic blow down bar is directed against the bag blank and forces the bag blank into engagement with the conveyor.

Abstract: An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.

Abstract: A converting line has a unwind machine with a load station assembly and a vertical movement assembly. The load station assembly rotatably supports a roll as the web is unwound during a first portion of an unwind cycle. The vertical movement assembly rotatably supports the roll during movement between lowered and raised positions during a second portion of the unwind cycle. A lower brake assembly controls rotation of the roll in the load station assembly, and an upper brake assembly controls rotation of the roll with the roll in the vertical movement assembly. With the roll rotatably supported in the load station assembly, the converting line control generates signals for the lower brake assembly to control an unwind rotation rate of the roll. With the roll rotatably supported by the vertical movement assembly, the control generates signals for the upper brake assembly to control the unwind rotation rate.

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 rewinding machine winds web material into a log. The machine has a winding drum that is rotatable about a center axis and about which the web material to be wound is directed. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the web material is directed when winding the web material into the log. The continuous loop is configured to move in a direction generally opposite of a direction of the winding drum at the nip. The continuous loop is configured to change speed relative to a speed of the winding drum during winding the web material into the log about a lead edge of the web material. The continuous loop is positionable relative to the winding drum at the nip to accommodate winding the web material into the log about the lead edge of the web material and to sever the web material.
