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 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.

IPC: B65H18/14
Abstract: A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.

Abstract: A system has first and second winding drums and a core feeder for inserting a core into a winding nest for forming a convoluted roll. The leading edge of the web is engaged with a threading belt and directed around the first winding drum and through the winding nest to a position where the leading edge is beyond where the core feeder inserts the core into the winding nest thus providing an excess portion of the web between the leading edge and the core feeder core insertion position. A thread-up core is inserted into the winding nest and rotated with the winding drums so that the excess portion moves around the thread-up core. The leading edge is separated from the threading belt, the excess portion of the web is wound around the thread-up core, and the web from the supply is wound around the thread-up core.

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 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: An overwrap feed station wraps a product with an overwrap material by drawing the overwrap material around the product to form a tube around the product as the product moves through the feed station. The feed station is configurable in first, second, or third configurations based upon a desired location of a longitudinal seal to be formed on the tube around the product. A first former is configured to guide the overwrap material through the entrance of the feed station so that longitudinal edges of the overwrap material overlap on a first side of the tube during wrapping of the product. The second former is configured to guide the overwrap material through the entrance of the feed station so that longitudinal edges of the overwrap material overlap on a second side of the tube during wrapping of the product. The third former allows forming the seal on the corner.

Abstract: An overwrap feed station wraps a product with an overwrap material by drawing the overwrap material around the product to form a tube around the product as the product moves through the feed station. The feed station is configurable in one of first and second configurations based upon a desired location of a longitudinal seal to be formed on the tube around the product. A first former is configured to guide the overwrap material through the entrance of the feed station so that longitudinal edges of the overwrap material overlap on a first side of the tube during wrapping of the product. The second former is configured to guide the overwrap material through the entrance of the feed station so that longitudinal edges of the overwrap material overlap on a second side of the tube during wrapping of the product. The second side is transverse to the first side.

Abstract: The invention relates to a device and method for cleaning the surface of a printing roll, such as an anilox roll. The device includes a laser-equipped assembly adapted to project a laser beam on the surface of the printing roll. The laser-equipped assembly uses a reflector and a lens to guide the laser beam along a predetermined path on the surface of the printing roll. In some embodiments, an autofocus system may be included to move the lens so that the desired focal point for the laser beam on the printing roll surface is achieved.
