Abstract: A core end engagement assembly is provided for a rewinding machine. The core end engagement assembly is configured to engage an end of the core and transmit rotational movement to the core during winding of the web material about the core. The assembly may include a drive housing. A chuck may project from a first end of the drive housing and may be configured to engage the end of the core. A first actuator may reciprocate the drive housing along a central axis of the core between an engagement and disengagement position of the chuck relative to the core. A second actuator may be mounted on the drive housing. The second actuator may be configured and adapted to move the chuck between release and hold positions. A flexible drive shaft operatively connects with and rotationally drives the chuck.

Abstract: 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.

Abstract: A method of forming a roll of convolutely wound web material. The method includes applying adhesive to an elongated mandrel, winding web material around the mandrel to form a roll of convolutely wound web material, rotating the mandrel relative to the roll to smear the adhesive, and removing the mandrel from the roll. The smearing can be in a circumferential direction. The adhesive can be applied longitudinally along the mandrel. The adhesive preferably has a viscosity within the range of 3000 to 18,000 cps. Preferably, the method includes pulling the mandrel longitudinally before the step of removing the mandrel from the roll. The pulling can reduce the mandrel diameter and/or can increase its length. The rotating can be conducted before the pulling, during the pulling or during the winding. The rotating can be conducted before or during the removing. The web material can be bathroom tissue or kitchen towel.

Abstract: A method for unwinding includes loading a first reel of web material into a first unwind position where the web is unwound. A splicing unit is then moved in the machine direction toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position where the web from the second reel is unwound once loaded. Then, the web from the first reel is spliced to the second reel, and the web of the first reel is thereafter cut. The process continues in the opposite direction after removing the first reel from the first unwind position. The web of the second reel is unwound in the second position, the splicing unit is moved toward the second unwind position until there is sufficient space to allow a further reel to be loaded into the first unwind position.

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: 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 machine forms a roll of convolutely wound web material. The machine includes a winding apparatus configured to receive a mandrel and the web material and wind the web material around the mandrel. A pulling device pulls the mandrel longitudinally to remove the mandrel from the roll after forming the roll. The machine further includes a restraint that engages the peripheral surface of the roll when the mandrel is pulled longitudinally to remove the mandrel from the roll. A method is also provided. In one aspect of the method, a web material is wound around a mandrel to form a roll of convolutely wound web material. The mandrel is pulled longitudinally after the step of winding the web material around the mandrel. The periphery of the roll is restrained from moving axially when the mandrel is pulled longitudinal. The mandrel is then removed from the roll.

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.
