Abstract: A rider roll system for exerting an even nip load force along the surface of a roll of paper being wound from a continuous on-coming web in a winder comprises a plurality of rider roll wheel elements, each of which is connected to a common source of hydraulic pressure to provide the same rolling nip force against the wound paper roll. The rider roll wheel elements are mounted to a beam which is translationally movable above the wound paper roll. The beam and individual rider roll wheel elements are moved upwardly as a function of the increase in the diameter of the wound paper roll. The relationship of the beam movement relative to the diameter of the wound paper roll is controlled by a programmable logic controller. The individual wheel elements are loaded against a counter-balance force so as to provide equal, but cushioned, nip force against the surface of the wound paper roll at short intervals along its length.

Abstract: A winder for continuously winding a traveling web such as paper onto a large roll with a support roll in contact with the roll being wound such as where the support roll is one or both of a pair of parallel horizontally extending drums with the outer surface of the drum being of rubber with embedded nonextensible annular cords and the surface being supported by a plurality of inflatable chambers along the length of the drum so that the outer surface of the drum deforms with contact with the roll being wound and accommodates irregularities along the length of the roll being wound.

Abstract: An automatic decurling apparatus is provided for webs of paper material in which two small diameter decurling bars are adjusted into both sides of the web run between two closely spaced rollers around which the web passes in an S-wrap. The decurling bars can be independently adjusted into the web in varying degrees to compensate for predominant curl in one direction of the web. Additional decurling can be obtained by chilling the rollers, incorporating high-intensity dryers in the web path or by moisturizing one or both sides of the web prior to its passing the decurling bars.

Abstract: Web severance is effected between non-contacting radially opposed severance points of circular edges on rotary upper and lower members between which continuously running paper web to be slit is engaged, the space between the severance points being sufficiently less than the thickness of the paper web and so related to the physical properties of the web as to cause severance of the web as a result of web fiber failure separation fracture at the point of maximum compression.

Abstract: Apparatus for the shingling of cut sheets of paper as they pass between conveyance on a high-speed tape conveyor and a low-speed tape conveyor is provided by a two-stage slowdown arrangement. At the first stage, a slowdown mechanism, comprising two rolls arranged respectively above and below each sheet passing through a drop-off area from the high-speed conveyor to the low-speed conveyor, serves to engage the tail portion of the sheet in a nip such that the sheet is slowed down to a speed approximately 30 to 40% of the speed of the high-speed conveyor. In this manner, the lead edge of a next succeeding sheet overlaps with the trailing edge of the nipped sheet in a drop-off area from the high-speed tape conveyor.

Abstract: A device for widthwise control of web material, comprises bar structure having resiliently bendable beam means for effecting a primary bowed adjustment. A set of side-by-side independent but cooperative wrap area members are carried by the beam means and are adapted to be individually selectively adjustable relative to the beam means to effect secondary adjustments incrementally at any of the members, without altering the primary bow relation, for correctionally compensating for uneven tension in any part of the web material, such as may be caused by web thickness, bulk or length.

Abstract: A means and method for handling trim strip slit from the margin of a travelling web, comprising rotary means by which biasing forces is applied to the strip away from the slitter into the chute. Within the chute relatively low velocity means advance the trim strip in a foldably bunched condition toward the bottom of the chute where the bunched trim strip is then transported away from the chute. Low velocity air, as well as rotary members are provided in the chute for effecting the foldable bunching and advancing of the trim strip. Either or both of low velocity air and mechanical conveying apparatus may be provided for transporting the trim strip away from the bottom of the chute.

Abstract: A gate station incorporates air pressure flows to direct clips in a production stream through the station and to selectively divert defective clips into a separate reject steam. Mounted on a support plate in the station are an upstream manifold, continuously supplied with low pressure air, and a downstream manifold, having a plurality of downwardly directed air ports and selectively supplied with high pressure air. Air flow from the upstream manifold is directed laterally over the upper surface of a clip so as to enable atmospheric pressure to maintain the clip travelling through the gate station in the production stream. If a clip is to be diverted, the downstream manifold is injected with high pressure air causing blasts of high velocity air through the downwardly directed ports. This high velocity air disrupts the flow from the upstream manifold and forces the leading edge of the defective clip downwards, pressing the clip into the reject stream.

Abstract: Rigid support for adjustable slitter blade heads enables permanent factory setting of slitting overlap and the rake and toe-in angles. The upper blade is mounted on its blade head for both radial and axial movement relative to the lower blade without requiring resetting of the blade overlap and rake and toe-in angles. The blades are replaceable without requiring resetting of the blade cutting overlap and rake and toe-in angles. Full adjustment of the blade supporting heads across the web path is provided for. Setting efficiency is greatly improved.

Abstract: Paper sheets are advanced seriatim between high speed upper and lower conveyor belts across a gap onto a slower speed multi-belt conveyor with which the upper high speed belts cooperate to form a sheet controlling tunnel. Static eliminating and sheet knock-down air is directed through the upper high speed belts and into the sheets traversing the gap. Advance of the sheets across the gap is facilitated by impermanent wave-like longitudinal stiffening rib deflection of the sheets where they leave the high speed conveyor belts. After each sheet has been fully received on the slow speed conveyor, its high speed travel is stopped by stop roll means to assure overlap of a succeeding sheet thereon. The stop roll means cooperate with the slower speed conveyor belts to effect impermanent wave-like longitudinal jam preventing stiffening rib deflection of the sheets.

Abstract: The instant invention concerns a cartoning assembly which operates in conjunction with a sheet stacker to pile sheets directly in their carton. The assembly loads a three-sided carton having an open top into the stacker and supports the carton there such that sheets accumulate in the carton. After a predetermined number of sheets have been piled in the carton, succeeding sheets piling into the stacker are segregated and separately supported away from the predetermined pile. The carton is then transferred to a discharge conveyor for processing and lidding. Meanwhile, a further carton is loaded into the stacker and supported beneath the succeeding pile. The succeeding pile is then deposited into the further carton. The further carton is supported in the stacker until the predetermined number of sheets accumulate and the process repeats.

Abstract: Cooperating slitter blades in a slitter for high bulk traveling paper web material attain high cut point pressure and minimum slit plowing and dusting as a result of critical cooperation of the slitting edges of the blades wherein one of blade edges rotates in a plane parallel to the longitudinal axis of travel of the web, and the slitting edge of the other of the blades cooperates to a penetration or overlap extent of less than 0.030 inch at a rake angle of 0 to 10 minutes and a toe-in of 5 to 30 minutes. Where the other blade edge is of high angle type an included angle between opposite faces of the edge of 15 to 30 degrees is provided and where a low angle edge is preferred, the included angle between opposite faces of the blade is between 75 and 85 degrees.

Abstract: An apparatus for slitting paper having a plurality of pairs of cutting elements disposed transversely with respect to the direction of movement of the web and a pair of arcuate support boards extending about one row of slitter elements to a point closely adjacent the overlap of the slitter elements to provide an arcuate path of travel for the web as it passes through the cutting area. The arcuate support boards are mounted for rotation about transverse axes to facilitate rotation of the boards away from the cutting elements and thus provide access to such cutting elements for adjustment and maintenance.
