  • Patent number: 10358767
    Abstract: Methods and components produced from carbon fiber pre-impregnated composite precursor materials (pre-preg) having enhanced flowability and moldability are provided. Discontinuous cut regions are introduced into a pre-preg. A sheet of pre-preg may be contacted with a patterned surface having a plurality of non-contiguous staggered cutters, so that the contacting creates discontinuous cuts in the pre-preg. A plurality of staggered discontinuous cut regions are formed in the plurality of continuous carbon fibers that define a first plurality of carbon fibers having a first length and a second plurality of carbon fibers having a second distinct length. The patterned surface may be provided on a cutter device that is a roller or a plate having the non-contiguous staggered cutters formed or disposed thereon. The discontinuous cut regions that are formed in the pre-preg reduce stiffness and improve moldability/flowability when forming carbon fiber polymeric composites, while retaining high strength levels.

  • Patent number: 6820529
    Abstract: A cutting mat includes at least one edge having a nonlinear shape. By nonlinear shape, it is meant that at least one edge of the cutting mat does not follow a single, straight path across the entire length of that edge. For example, a cutting mat may have opposing nonlinear circumferential edges. The cutting mat may include nonlinear axial edges in lieu of, or in addition to the nonlinear circumferential edges.

  • Patent number: 6722246
    Abstract: The invention is a cylinder cover engageable with a channel. The cylinder cover includes a flexible blanket with two ends, the ends configured to substantially abut when the blanket is circularly wrapped. Further, the cylinder cover includes a female member attached to the first end of the blanket, the female member having a leg connected with and opposing a resilient engaging element by a base member. The resilient engaging element is configured to frictionally engage a sidewall of the channel. Attached to the second end of the blanket is a substantially rigid male member. When engaged with the channel, the blanket is substantially continually supported by a rigid substrate.

  • Patent number: 6718855
    Abstract: A rotary die cutter for cutting a series of irregular-shaped blanks from a continuous web. The rotary die cutter includes a male die cylinder that has a series of die cavities formed along its outer circumference. Each of the die cavities includes a surrounding cutting edge that defines the shape of the blank to be cut. The male die cylinder is pressed into engagement with either an anvil cylinder or a female die cylinder to form either crush-cutting or shear-cutting nips therebetween. The continuous web is fed into the cutting nip such that the cutting edges of the die cavities contact the web to cut the blanks from the web. A plurality of vacuum ports positioned in the die cavities along the outer circumference of the male die cylinder are connected to a source of vacuum contained in the male die cylinder to remove the die-cut blanks from the web. The die-cut blanks are vacuum-transferred to a stacking unit, while the scrap web is continuously discarded by air-conveying removal.

  • Patent number: 6718859
    Abstract: A three hole punch system for use in an image capturing device. The three hole punch system uses elastomer rollers that punch holes in the edge of a document as is passes between the two rollers. If desired the rollers can act as a transport for the document without punching holes in the document. After the holes are punched the slugs are pushed back into the holes and the document is retrieved by the operator.

  • Patent number: 6698326
    Abstract: A lockup device for securing cutting mats to a rotary anvil comprises a base portion, one sidewall, and a wedge portion, and is adapted to be inserted into the channel of the rotary anvil such that the sidewall of the lockup device is adjacent a wall of the channel. A cutting mat having opposing first and second flanged ends is wrapped around the rotary anvil. The first flange is compressed between the locking wedge and the sidewall of the lockup device. The second flange is compressed between the locking wedge and a channel wall. As such, the locking wedge and cutting mat are frictionally secured to the rotary anvil. Further, the cutting mat may be quickly repositioned by releasing the second flange from the channel. When the cutting mat is unwrapped from the rotary anvil, the lockup device remains secured to the first flange, allowing for quick repositioning.

  • Patent number: 6681666
    Abstract: An improved rotary die cutting apparatus and method for removing scrap material from work pieces such as paperboard blanks. One of the dies of a pair of rotary cutting dies is provided with gripper elements that extend over at least a portion of the area of the die corresponding to the areas over which the scrap portions are generated. The gripper elements grip, without piercing completely through, the scrap portions generated by the cutting operation of the dies. A stripping knife extends across the die carrying the scrap portions at a height above the gripper elements that provides clearance between the gripper elements and the stripping knife but contacts the scrap portions retained on the gripper elements.

  • Patent number: 6668694
    Abstract: An anvil blanket is molded urethane sheet material and formed with a plurality of interlocking fingers at mating opposing blanket ends and includes a depending projection which mates with a channel in the anvil about which the blanket is wrapped. A urethane insert having a hardness greater than the blanket material is molded embedded in the blanket to form a portion of the fingers and a portion of the projection depending from the fingers. A woven fiberglass fabric provides support for the blanket and which fabric is molded to the blanket. The insert has a durometer greater than that of the blanket to minimize the formation of surface recess defects at the projection which might otherwise occur due to the increased thickness of material at the projection. The insert may have other properties different than that of the blanket material including rebound, modulus, and cut and tear strength among others for resisting the formation of blanket surface defects.

  • Patent number: 6629482
    Abstract: A cutting mat comprises a cutting mat body and a lock assembly arranged to secure the cutting mat to a rotary anvil. The lock assembly comprises male and female locking members formed at opposite ends of the cutting mat and integral therewith. There are no metal frames or other components welded or otherwise secured to the male or female locking members. The female locking member slips into an axial channel on a rotary anvil. The cutting mat is wrapped around the rotary anvil, and the male member is inserted into the axial channel in locking relationship with the female locking member. Further, the axial edges of the cutting mat are formed in mating, complimentary serpentine shape to prevent a cutting blade from slipping into the seam between adjacent cutting mat surfaces.

  • Patent number: 6612214
    Abstract: A molded anvil blanket is formed with a projection depending at each end, the ends for abutting when wrapped about the anvil, the anvil having a transverse channel for receiving the projections. The projections mate to form a common recess enclosed by a metal angle member secured to each projection. The angle member and projections have a transverse slot for mounting the blanket end and projections on a pneumatic mechanism attached to the anvil. The mechanism includes an air cylinder secured to the anvil in a radial anvil bore. The cylinder has a shaft which extends in response to pressurized air. A spring attached to the air cylinder and to a T-bar which releasably engages the blanket common recess normally biases the projections locked into the channel in a fail safe mode. The activated air cylinder lifts the projections out of the channel so the blanket ends can be manually released from the anvil by sliding the T-bar out of engagement with the projections via the slots in the projections and angle member.
