摘要： A nonwoven web is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. A baffle plate may be inserted into the mixing zone and acts to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen. When different fibrous materials are fed to the lickerin along their length, the vertical composition of the web is altered.

摘要： A lickerin and feed mechanism create a supply of individual fibers which follow the rotation of the lickerin. These fibers are deflected from the lickerin in the form of a stream by means of a plate arranged parallel to the lickerin. A conveying screen intercepts the stream of fibers and accumulates them into a web without the use of a high velocity stream of air to doff the fibers from the lickerin or to capture fibers on the conveyor. Further, the housing for the apparatus is opened so that there are no seals to compress the web after it is produced. Multiple lickerins and feed mechanisms may be spaced along the conveying screen to create multiple-layer or blended products. The feed mechanisms may include devices for spraying particulate material on previously formed layers or blending it with fibers as a layer is formed.

摘要： A web or structure is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. Segmented baffle plates may be inserted into the mixing zone to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen. A segmented feed may be used to advantageously deliver different fiber materials at different rates to each lickerin. Radially layered composite web structures having circular cross-sections may be formed with the same apparatus by forming the conveying screen into a U-shape and selectively controlling the air flow through the screen.

摘要： A pad is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated in pocket molds moving on a conveying screen that is moved parallel to the axes of the lickerins. A baffle plate may be inserted into the mixing zone and acts to control the lateral or cross-sectional composition of a web formed by the fibers accumulated in the molds. When different fibrous materials are fed to the lickerin along their length, the vertical composition of the web is altered. Because of the pocket molds the pads are formed as individually shaped products.

摘要： An apparatus permitting formation of a flanged product with the wider flanged portion in engagement with a foraminous transporting device. The apparatus uses a mold-like former having a narrower or smaller portion separated from the foraminous surface by a wider flange forming portion. The flange forming portion is adjacent to the foraminous surface and is separated from the foraminous surface after pad formation leaving the formed pad behind.

摘要： A cylinder, for example a lickerin, and feed mechanism create a supply of individual fibers, for example pulp, which follow the rotation of the lickerin. These fibers are deflected from the lickerin in the form of a stream by means of a plate arranged parallel to the lickerin. A conveying screens intercepts the stream of fibers and accumulates them into a web without the use of a high pressure stream of air to doff the fibers from the lickerin or to capture fibers on the conveyor. Further, the housing for the apparatus is opened so that there are no seals to compress the web after it is produced. A feed tray located next to the lickerin can be used to include other particulate materials (fiber or granules) in the main fiber stream and a tapering of the deflector plate can separate the component of the blended fiber-particulate material stream into layers in the resulting web distinguished by particle weight.

摘要： Apparatus for forming three dimensional shaped webs. The apparatus controls the flow of entraining air for an air laid web by restricting passage of the air through selected zones of a condensing surface. By limiting the open area in a zone of a suction plate the amount of fibers condensed over the zone is reduced permitting control of location of and amount of deposit. The duct work defining the conduit for the entraining air may also be shaped or provided with blocks to prevent scavenging of fibers which have already been deposited.
