  • Patent number: 6699366
    Abstract: A press fabric for the press section of a paper machine has a base fabric which includes a nonwoven mesh fabric. The base fabric, or a layer thereof, is assembled in integral form using a strip or strips of the nonwoven mesh fabric. The assembly may be effected by spirally winding the nonwoven mesh fabric in a plurality of non-overlapping turns, by abutting each turn of the nonwoven mesh fabric against that previously wound, and by joining each turn of the nonwoven mesh fabric to that previously wound to form an endless loop. Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop.

  • Publication number: 20030168194
    Abstract: An industrial process fabric is embossed in a device, such as a continuously operating two-roll calender having a preselected embossing pattern. The roll(s) of the calender may alternatively themselves be engraved or etched to provide the embossing. Embossing takes place with controlled temperature, pressure, speed and gap (between the rolls) settings. The fabric may be a forming, press, dryer or TAD fabric used in paper and pulp production, pulp forming fabric or an engineered fabric used to produce nonwoven textile products by meltblowing, spunbonding, hydroentangling or air laid needle punching.

  • Patent number: 5713399
    Abstract: A method for manufacturing a papermaker's fabric by spirally winding a woven fabric strip, narrower than the intended width of the fabric, and the papermaker's fabric manufactured in accordance with the method, are disclosed. The fabric strip includes lengthwise and crosswise yarns, and has a lateral fringe along at least one lateral edge thereof, the lateral fringe being unbound ends of the crosswise yarns extending beyond the lateral edge. During the spiral winding of the fringed strip, the lateral fringe of a turn overlies or underlies an adjacent turn of the strip. The lateral edges of adjacent turns abut against one another. The spirally continuous seam so obtained is closed by ultrasonically welding or bonding the overlying or underlying lateral fringe to the fabric strip in an adjacent turn.

  • Patent number: 4992327
    Abstract: This invention relates to synthetic fiber thermal insulator material in the form of a cohesive fiber structure, which structure comprises an assemblage of:(a) from 70 to 95 weight percent of synthetic polymeric microfibers having a diameter of from 3 to 12 microns; and(b) from 5 to 30 weight percent of synthetic polymeric macrofibers having a diameter of 12 to 50 microns,characterized in that at least some of the fibers are bonded at their contact points, the bonding being such that the density of the resultant structure is within the range 3 to 16 kg/m.sup.3, the thermal insulating properties of the bonded assemblage being equal to or not substantially less than the thermal insulating properties of a comparable unbonded assemblage. The invention also relates to the method of preparing said material.

  • Patent number: 4633920
    Abstract: The invention is an improvement in the feed mechanism for a lead-forming machine for axial-leaded electronic components. The invention comprises a combination of a reverse threaded shaft, controlled by a hand-manipulable knob, which shaft in turn may precisely and rapidly mechanically control one or more walls of the feed chute of the forming machine, the function of which is to orient a small object, such as an electronic component, so that the object assumes a predetermined position with respect to a forming element which then imparts a bend, twist or other change in the shape of said object. The invention is particularly useful for rapid set-up to impart predetermined bends in electrically conductive leads used in capacitors, transistors and similar components for electronic equipment.
