Abstract: A clasp has a prong and a housing with clamping wedges and actuator wedges. The clamping wedges are spaced circumferentially around the prong within the housing and moveable within the housing via the actuator wedges. In a disengaged position, the clamping wedges are spaced radially outwardly from the outer surface of the prong at a distance sufficient such that a tube is insertable between the prong and the clamping wedges. In the engaged position, the clamping wedges are positioned radially inward of the disengaged position so as to press the tube against the prong. Each actuator wedge is slidingly engageable with the corresponding clamping wedge along complementary and cooperating wedge-shaped surfaces of the actuator wedge and the corresponding clamping wedge. The wedge-shaped surfaces include cooperating elongated protrusions and elongated slots.

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 pull station has top and bottom continuous loops with the top continuous loop disposed on a frame and movable relative to the bottom continuous loop with a frame actuator connected with the frame. The frame actuator has a sensor for sensing position. A stop, adjustable with a stop actuator and having a load sensor, is operatively engageable with the frame and prevents movement of the top continuous loop toward the bottom continuous loop. A control determines a distance between the top and bottom continuous loops based upon the actuator position sensor; determines a force imparted to webs based on the stop load sensor, the weight of the frame and the top continuous loop, and a force imparted to the top continuous loop by the frame actuator as the webs are conveyed in the pull station; and controls the pull station based upon the distance and/or force measurements.

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.
