Abstract:
A process for making a fibrous panel member and a flooring structure is disclosed. The flooring structure has a subfloor, a surface layer, and an insulative pad disposed between the subfloor and the surface layer. The insulative pad has an MDI binder and reinforcement fibers distributed uniformly and randomly within a first plane. The process includes mixing a porous fiber material with a MDI adhesive. The fiber batt is compressed between a pair of porous belts. Steam and heat are applied to the compressed batt to form a bound flexible batting material.
Abstract:
A system and method of producing both loose cellulose insulation and bonded fiber/cellulose insulation products utilizing shredded paper particles, including making shredded paper particles in a shredded paper particle line and diverting a portion of the shredded paper particles to a bonded fiber/cellulose product line whereby the shredded paper particle line forms an in-process production and delivery of shredded paper particles to the bonded fiber/cellulose product line. Moisture is added to the shredded paper particles at the bonded fiber/cellulose product line, and bonded fiber/cellulose insulation products are produced with the bonded fiber/cellulose product line from the diverted portion of shredded paper particles and loose cellulose insulation is produced from shredded paper particles that are not diverted from the shredded paper particle line.
Abstract:
The present invention provides an insulating batt of non-woven fibers. This batt is comprised of synthetic fibers, natural fibers, bonding materials or any mixture thereof. It is characterized by an axis of length, an axis of width, and an axis of thickness, wherein the extreme fibers at one end of said axis of thickness form the proximal face of the batt, and the extreme fibers at the other end of said axis of thickness form the distal face of the batt and wherein either said distal face, said proximal face or both faces are essentially non-planar faces.
Abstract:
A fiber opening device comprising a feed section opening into the fiber opening section. The opening section includes a cabinet with an inner chamber, a waste removal chamber and a fiber web removal unit. The inner chamber includes a doffing roll and a contaminant collecting area located above first and second opening rolls. A main roll is located beneath and between the opening rolls and a waste removal section and a fiber web removal section are located beneath the main roll. In operation, fibers delivered into the inner chamber are first acted on by primarily one of the opening rolls which creates a tumbling action in which contaminants are dislodged and deposited into the contaminant receiving area while other fibers are picked up by the second opening roll carried to and doffed onto the main roll forming a fiber web for delivery to the fiber web removal section.
Abstract:
The instant invention is directed to an arrangement for forming a stable fiber web having high loft and high resilience. The arrangement includes a cabinet receiving opened and blended fibers connected with a fiber web forming chute which receives the opened and blended fibers from the cabinet. The forming chute includes a first and second wall and fiber contacting elements which assist in urging the fibers through and out an exit of the chute in an evenly distributed condition while forming the fiber web. The fiber contacting elements include a fiber inter-engaging device associated with at least one of the first and second walls, said inter-engaging device acting said outer fibers causing these fibers to inter-engage creating a stable outer surface over the fiber web.
Abstract:
A chute feed assembly for opening and moving fibers through a chute delivery system into an infeed chute for an opening station. The chute feed assembly includes a beater for opening the fibers which is drivable in a selected of two directions. The beater delivers the opened fibers into a fiber batt forming chute where they are formed into a fiber batt which is then delivered to further processing. The infeed air flow is assisted by providing non-friction chute surfaces to allow even fiber flow throughout the chute. Also, the air flows of densified air controlled across the fiber batt forming channel to provide for even fiber distribution of selected density. The assembly provides for all drive motors to be mounted outside the interior of the chute feed assembly reducing heat build-up within the chute feed assembly.
Abstract:
In a mixing and opening device for pneumatically supplied flocculent fiber material, wherein fiber material is fed, by use of transport air and through a supply conduit, to a blow-in chute section of a hopper, wherein said blow-in chute section comprises a screen means for separating the fiber material from the transport air, and an air collecting chamber arranged behind said screen means for discharge of the transport air, and wherein, on the lower end of said hopper, the fiber material layered in said hopper can be fed via an intake means to an opening means, it is provided that the intake means comprises two intake rollers of different sizes.
Abstract:
A device is provided for feeding fiber material into a textile machine, comprising a horizontal transport channel (10), a feeding chute (2) branching vertically downward from the transport channel (10), an air-collecting chamber (3) separated by an air-permeable intermediate wall (9) from the feeding chute (2) connected with the transport channel (10), the air collecting chamber (3) being provided with a closable blow-off opening for discharging the flow of transport air, and a fiber transport device (18) at the lower end of the feeding chute (2), wherein at least one blow-off opening (6) is arranged at the lower end of the air-collecting chamber, alternately suddenly blowing off or shutting off the flow of transport air (7).
Abstract:
In an opening device for opening pressed fibre bales, e.g. cotton and viscose staple bales and the like, comprising a plurality of opener rolls (3,4) on which a plurality of milling discs (14) are arranged side by side such that they are offset with respect to the milling discs (14) of the adjacent opener roll (3,4), and comprising a grate (10), the bars (11) of which extend between the milling discs (14), it is provided to dispose a baffle sheet (8) with a cross section of a substantially gabled roof-shape is disposed in parallel to the roll axes (6,7) of the opener rolls (3,4) between said two opener rolls (3,4), the tip of the sheet protruding beyond the grate (10) into the lower space between the opener rolls (3,4).
Abstract:
A textile fiber opening and removing apparatus (1) is disclosed having a tower (2) wherein at least one cantilevered arm (5, 6) is supported on the tower in such a manner that the cantilevered arm rotates about a longitudinal axis of the tower and a central axis (31) of a fiber discharge section (11) to various angles. Control means (35) mutually controls and coordinates a lift motor (24) and a traction motor (28) to move cantilevered arm (5) and milling unit (7) over a prescribed inclined path. In this manner, fiber bales (4) may be continuously fed at the top of the inclined path for fiber removal.
