  • Patent number: 6773388
    Abstract: The present invention is directed generally to a folder apparatus for sheets, and more particularly a folder with a fold path transverse to a feed path. In an embodiment, the folder comprises a channel for receiving a sheet, feed rollers for feeding the sheet along the feed path and through the channel, the feed rollers are axially aligned with the feed path, guide rollers positioned transverse to the feed path for feeding the sheet along a fold path to pinch rollers which pinch the sheet to form folds. The paper path does not reverse and the folding action is smooth so that noise and vibration are reduced. Also, the folder has a smaller footprint than other folders.

  • Patent number: 6740024
    Abstract: The folding station of a rotary printing press has a folding cylinder on which the printed paper web is cut into sections. Mounted opposite the folding cylinder, a jaw cylinder has cut in its surface several jaw cavities each extending parallel to the jaw cylinder axis for receiving the midpart of the web section as the same is inserted therein by a folding blade on the folding cylinder. Each jaw cavity has mounted therein a series of fixed jaw parts and a series of movable jaw parts, the latter being jointly movable toward and away from the former for engaging and folding the midpart of the web section. The two outmost ones of the movable jaw parts are positioned closer to the fixed jaw parts than are the other, medial movable jaw parts, in order to more firmly engage the margins of the web section without causing ink offset between the contacting surfaces of the image areas of the web section.

  • Patent number: 6740025
    Abstract: A method of folding a gas bag for a vehicle occupant restraint system comprises the following steps: first, the gas bag is unfolded between a base and an opposing surface. A spacing is provided between the base and the opposing surface, which corresponds to a height of a housing into which the gas bag is to be inserted after folding. Then, a folding funnel is provided which comprises one end having a large cross-section and one end having a small cross-section, the large cross-section being larger than or equal to a cross-section of the gas bag when unfolded between the base and the opposing surface, and the small cross-section corresponding to a cross-section of the housing; beginning with its large cross-section. Finally, the folding funnel is placed over the unfolded gas bag and moved relative thereto such that the gas bag is pushed together on the base by the folding funnel to the small cross-section.

  • Patent number: 5937757
    Abstract: In order to permit automated setting of operating parameters while also facilitating the removal of paper jams, a device for adjusting the gap size between folding rollers of a rotary press folding machine includes a pair of counter-rotating folding rollers which define a folding nip or gap therebetween. Each folding roller is mounted to one end of a pivoting support arm, and a link arm is slidably and pivotably mounted to the other end. An extensible member connects the link arms to each other, which enables the distance between the rollers to be quickly and easily adjusted. An inflatable bag is disposed between the support arms which forces the rollers towards each other to resist spreading of the rollers when a paper passes through the gap between the rollers. The bag can be quickly deflated from a remote location to allow removal of jammed papers, and can be quickly re-inflated to the desired setting to minimize down time.

    Abstract: A mechanical apparatus and method for producing a folded paper rose from an elongated strip of paper. The apparatus is operated by feeding an elongated paper strip through a rotating shuttle assembly, and securing the end of the paper strip onto a slotted stem which is rotated simultaneously with the shuttle assembly. Rotating the shuttle assembly causes a pair of shuttles to cooperate with a paper folding member adjacent the ends of the shuttles to produce a series of sequential folds in the paper strip. Meanwhile, the stem is simultaneously rotating to assemble the folded paper around the stem. Once the paper is fully assembled around the stem the folded paper strip is compressed toward the top of the stem to form a compact flower assembly at the end of the stem.

  • Patent number: 5129876
    Abstract: A paper folding machine is improved by grooving the fold rollers. Grooves in the fold rollers extend along a curved path, from one end of the roller and terminating adjacent to the center of the roller. Complementary grooves extend from the opposite end of the roller towards the center of the roller. The surface of the roller is rubber or the like, and has a durometer hardness in the range of 65 to 72 Shore A. The grooves are shallow enough that the paper is not crimped or wrinkled by the grooves.

  • Patent number: 5029828
    Abstract: A continuous paper folding device for a printing machine has a pair of thin elongated folding plates which are located at both sides of a paper transferring path for a continuous paper, provided by a plurality of transferring rollers and are arranged so as to be rotatable around the respective axes of rotation which extend in parallel to each other. When the pair of folding plates are operated by a driving motor, the folding plate are rotated in correspondence to rows of perforations formed in the continuous paper so that it is correctly folded in a zigzag form on a paper receiving table.

  • Patent number: 5007890
    Abstract: A folder plow for a web of material in which the plow is positionable transversely of the longitudinal movement of the web material and has a folding disk rotatable on an axis convergent with the web and being adjustable by tilting about its axis of rotation to position its folding edge at different angles to the plane of the web to obtain a wrinkle free fold without gussetting and to prevent marking. The plow has a cylindrical section rotatable about an axis parallel with the plane of the web, which section is partially telescoped over the disk and provides a shroud for a major section of the disk, the disk having a small sector projecting radially from the contiguous portion of the cylindrical section.

  • Patent number: 4848126
    Abstract: The invention relates to a drywall corner bead spreader device. The device comprises a stationary support portion and a movable pressure applying portion. When a length of drywall corner bead is placed on the stationary support portion with its flanges facing upwardly adjustment of the movable pressure applying portion into contact with the flanges will force the flanges to assume an included angle greater than its normal ninety degree orientation. The movable pressure applying portion includes a freely rotating spreader ball which will rotate as the corner bead is pulled from beneath the spreader ball resulting in reduced friction and providing a uniform included angle to the flanges in excess of ninety degrees.

  • Patent number: 4767394
    Abstract: A method and apparatus for making axial-flow filters wherein a sectorial-shaped sheet of filter material having corrugations therein parallel to the curved ends thereof is made from a flat sheet of filter material, and thereafter the corrugated sheet is made into an annulus to obtain the final product. Initially, an edge portion of a flat sheet of filter material is attached to a sectorial-shaped mold, having a mold surface defined by curved ridges and valleys parallel to the curved ends of the mold, so that the sheet is slanted up away from the mold surface from the smaller curved end of the mold. Thereafter a set of curved forming blades is moved down toward the mold to engage the sheet and to fold it successively and consecutively across the ridges of the mold and beneath the edges of the blades into the valleys of the mold to corrugate the sheet.
