摘要:
A method of controlling stack back pressure in folding apparatus incorporating sensing the bulk of a stack issuing from folding rolls, forming a signal corresponding to the sensed bulk, comparing the signal with a predetermined signal range and changing the size of an embossing nip gap or pressure whenever the signal is outside of the range.

A surface winder and method in which a stationary upper winding roll, a lower movable winding roll and a rider roll form a three roll cradle, the lower winding roll being reciprocated to control the position of a partially wound core until the rider roll returns to cradle position after permitting passage of a previously wound log and in which a compensator roll is provided to control web slack after cutoff and transfer.
摘要:
Apparatus and method for stacking product such as flexible paper towels including a slotted wheel in combination with at least two endless chain conveyors equipped with finger assemblies which are orbitally offset so that while one finger assembly of one chain conveyor is accumulating a plurality of substacks, a first finger assembly of the other chain conveyor is being readied to take over the development of a successive stack, and programmable servo motor associated with the chain conveyors for varying the finger assembly advance during different portions of the orbital movement of the finger assemblies.
摘要:
A system includes a camera, a weigh-in-motion scale, and a processor. The camera is configured to capture one or more images of a vehicle as the vehicle goes over the weigh-in-motion scale. The weigh-in-motion scale is configured to generate one or more weight measurements of the vehicle as the vehicle goes over the weigh-in-motion scale. The processor is operatively coupled to the camera and the weigh-in-motion scale. The processor is configured to determine an acceleration of at least a portion of the vehicle based at least in part on the one or more images of the vehicle. The processor is also configured to adjust at least one of the one or more weight measurements based on the acceleration.
摘要:
A surface winder and method employing recycled mandrels wherein a frame provides a winding path, a first winding drum for continuously advancing a web in the path and positioned on one side of the path, a mandrel inserter for introducing mandrels sequentially into the path for contact with the web, a second winding drum on the frame on the other side the path for coacting with the first winding drum in developing a log and a stripper on the frame for stripping each mandrel sequentially out of its associated log.
摘要:
A composite wood article includes a plurality of four elongated triangular-shaped pieces and opposing pieces are substantially similar in cross-sectional dimensions. They are joined together to form a composite parallelogram in cross-section. One alternative embodiment includes using sector-shaped pieces that have been cut from generally cylindrical logs, while another embodiment includes triangular-shaped pieces cut from readily available rectangular lumber. In the process of manufacturing the composite article, the four triangular-shaped pieces are first machined so they are properly sized and then after the appropriate application of adhesive to the surfaces which will form the connecting joints, the joinder base leg of each triangular-shaped piece is positioned so as to be juxtaposed against the adjacent joinder leg of the next adjacent triangular-shaped piece. Once all four triangular-shaped pieces are positioned properly, the loosely connected composite is then directed into a pressing station where suitable pressure is exerted on the plurality of joints to cure the adhesive. After the joints are cured, the composite article may then be machined to its final dimension.
摘要:
A preprinted web having a plurality of first repeating images is reprinted with a plurality of second repeating images which are in register with the first images. A register mark is printed on the web for each of the first images. When the web is reprinted, the positions of the register marks are sensed and compared with the positions of the second images, and the unwind tension of the web is adjusted to maintain the relative positions substantially constant.
摘要:
A method and apparatus for forming fluff pads and the like wherein fluff particles are drawn from a hammermill through a plurality of ducts through a moving screen under vacuum and wherein the ducts are characterized by reverse bends to densify the particle stream at the outside of the curvature for generally perpendicular deposition on the screen.
摘要:
A hanky delivery system including a folding mechanism slotted star wheel and collector/divider of the movable type wherein the collector divider is a chain loop having an upper turning radius positioned within the periphery of the slotted wheel and sized smaller than the bottom turning radius for the chain loop.
