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.

Abstract: A processing line includes a conveyor for conveying product from upstream processing equipment to downstream processing equipment. Data structures stored in a memory of a controller comprise a backlog set point for product to be processe. A product sensor for the conveyor is enabled to generate signals representative of a number of the products moving on the conveyor from the upstream processing equipment past the sensor to the downstream processing equipment. A conveyor speed sensor for the conveyor is enabled to generate signals representative of a speed of the conveyor. A backlog measurement for the conveyor based upon the product sensor signals and the conveyor speed sensor signals is determined. The backlog measurement is compared to the backlog set point to determine a difference in backlog. The controller is enabled to generate signals for controlling the processing line based upon the difference in backlog.

Abstract: A processing line processes logs of convolutely wound web material and has upstream and downstream sections. A main accumulator has buckets that receive, hold, and release logs. An input feeder receives logs from the upstream section and conveys them to a bucket of main accumulator. A loader has a loader accumulator and loader buckets that receive, hold, and release logs. A transfer conveyor between the main accumulator and the loader receives a log from the main accumulator bucket and conveys the log a loader bucket independently of the input feeder. The loader receives a log from the transfer conveyor. The loader conveys the log in the loader bucket to a discharge of the loader. The loader discharge discharges the log from the loader bucket to the downstream section of the processing line.

Abstract: A converting line includes a rewinding machine for winding web material into a log. For time points during a time period of the log wind cycle, predictive information representative of a log to be wound is generated and stored in a memory of a control of the rewinding machine. An image capture device is enabled to capture a plurality of images of the log being wound in the winding nest at the plurality of corresponding time points during the time period. Log image capture information is generated based upon the plurality of captured images and corresponding time points during the time period. The log image capture information is compared with the generated predictive log image information to determine a difference in log image. Revised predictive log image information is generated based at least in part upon a difference in the log image capture information relative to predictive log image information.

Abstract: An embosser/laminator machine has an adhesive unit releasably connectable with a main frame structure of the machine, and a roll extractor configured to move a roll between the main frame structure and an exchange position between the main frame structure and the adhesive unit when the adhesive unit is spaced from the main frame structure during removal and installation of the roll. The sub-frame comprising the adhesive unit may be formed with a bearing cap that cooperates with the main frame structure such that when the adhesive unit is connected with the main frame structure, the roll is operatively secured to the machine between main frame structure and the sub-frame of the adhesive unit for normal operation of the machine. When the sub-frame comprising the adhesive unit is released and spaced from main frame structure, the roll may be removed from and installed into the main frame structure.

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.
