Patent number: 5093962Abstract: 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.Type: GrantFiled: August 16, 1990Date of Patent: March 10, 1992Assignee: ChicopeeInventors: Allan P. Farrington, Gerald M. Marshall, Theodore J. Krainski

Patent number: 4952128Abstract: 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.Type: GrantFiled: September 22, 1987Date of Patent: August 28, 1990Assignee: ChicopeeInventors: Gerald M.
