Abstract: “A system controls the quality of products in output from a cutting machine, for instance, a log saw that has at least one cutting disc and a sharpening wheel. The control system comprises a PLC controller suitable for controlling the cutting and sharpening process and an inspection system suitable for scanning at a specific time instant, a set of quality values of a roll in output from the cutting machine. A processing unit receives the set of quality values and sends to the PLC controller a command aimed at performing an action consisting of increasing or decreasing one of the following parameters: sharpening time, sharpening frequency, and differential speed between the wheel and the disc, based on the comparison between the set of quality values and a reference quality value, and the action carried out at the previous time instant”.

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 a product type to be processed. 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 for delivery 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 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 and additional information related to the product type.

Abstract: A device and a method is disclosed to maintain plate and anilox mandrel position stability in print decks of a flexographic printing press. In one aspect, the mandrel bearings associated with at least one of the plate roll and the anilox roll are preloaded for the purpose of eliminating backlash and increasing the positional stiffness of the bearings, and thus the mandrel. In another aspect, the roll drive motor control system is enabled to provide a torque additive command the torque profile to maintain rotational consistency and otherwise overcome torque transients experienced by the motor during print bounce. Accordingly, the problem commonly referred to as print bounce and or print banding is alleviated.

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 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 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 flexible mandrel is provided for holding cores or core segments so that a roll of sheet material can be wound on the core segments in a winding machine. The mandrel and core segments are coupled through elastic interference between the mandrel and the core segments so that the core segments are arranged either adjacent to each other or spaced apart. A method for producing rolls of sheet material on the novel combination of mandrel and core segments feeds cores in an apparatus, transversely cuts the cores to form portions of core or core segments, feeds a flexible mandrel into the core segments for supporting and maintaining the axial position of the core segments. Coupling is by elastic interference between the flexible mandrel and the core segments to form an assembly in which the core segments are arranged on the mandrel spaced apart or adjacent one to the other.
