  • Patent number: 11731141
    Abstract: An apparatus includes first and second conveyor structures with first and second conveyor surfaces. The conveyor surfaces face each other and are arranged to define a comminuting space in the apparatus. The apparatus brings the conveyor surfaces in movement in the direction from a first end of the conveyor structures towards a second end of the conveyor structures, and the two conveyor surfaces are placed to face each other. The conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces narrows in the movement direction of the conveyor surfaces. The advancing movement of the conveyor surfaces brings about compression in material being comminuted. The conveyor surfaces are in a double-converging so that in addition to the convergence in the movement direction, the conveyor surfaces are additionally convergent in the transverse direction in relation to the movement direction, the comminuting space thus also being double-converging.

    Abstract: A method and apparatus for densification of fibrous material such as harvested cotton, preferably by a movement of the cotton continuously through a compacting zone on the harvester. In one aspect of the invention, the fibers are locked by differential translation of portions of the mass of compacted material to prevent a layer of material from springing back after compression. A continuous mat of compressed material with locked fibers is formed into a uniform, high density bale or module on the harvester. A cotton harvester compacting system includes an air system feeding harvested cotton into an accumulation area and to the compacting zone on the harvester. The cotton is compressed and fed through a shear zone which differentially translates the cotton and locks the cotton fibers into a uniform, compact mat. In one embodiment, the mat of compacted cotton is fed to a round baler on the harvester to form a dense round bale or module.

  • Patent number: 5979145
    Abstract: A method and apparatus for compressing and packaging compressible materials. The compression is carried out continuously between parallel plates which come closer to each other as they advance. As the plates advance, the materials are accompanied by a lower packaging film and an upper packaging film which are joined at the sides of the compressed materials at the end of compression.

  • Patent number: 5794527
    Abstract: A can crusher includes two endless belt assemblies arranged alongside each other with the mutually facing runs of said belt assemblies being arranged to define a converging gap therebetween in the direction of motion of the belt so that a can to be crushed fed into the converging space is progressively crushed as it moves between the belts. One of the belt assemblies is pivotally mounted relative to the other such that the angle of convergence can vary, the conveyance movement being controlled by, for example, gas-springs.

  • Patent number: 5773045
    Abstract: The device for working a dough strand into a thin dough sheet, comprises two superimposed endless conveyors the operative runs of which are facing one another and adapted to be driven in the same direction at the same speed. The operative runs confine a passage gap for the dough strand that gradually increases in height in the conveying direction. According to the invention, the operative run of the upper one of the two belt conveyors has, as seen in the conveying direction of the dough strand, a profile, that satisfies the equation: ##EQU1## in which Y.sub.x is the perpendicular distance between the operative run of the upper belt conveyor and the lower, flat belt conveyor at a point x in the passage gap between the two operative runs, and wherein a is a measure for the length of the conveyance path.

  • Patent number: 5700495
    Abstract: Continuous 3-D forming machine using upper and lower revolving endless, flexible, forming belts produces three-dimensional patterned products from heated thermoplastic material. The mold belts revolve synchronously in elongated oval paths around their respective carriages moving in opposed face-to-face relationship defining one or more travelling mold channels progressing from an entrance to an exit. Formable heated thermoplastic material feeds into the entrance, and attractive 3-D products proceed from the exit. Revolving mold surfaces are operated at least 25.degree. F. above room temperature, for example in a range of 110.degree. F. to 140.degree. F., for providing aesthetic surface qualities on products having content which may be foamed to densities in the range of about 0.9 to about 0.4. Thermoplastics in such travelling mold channels are appropriately chilled when differentials .DELTA.

  • Patent number: 5695599
    Abstract: Apparatus for making laminates such as a wood panel, in particular a chip board or a fiber board or the like, includes a prepress having an inlet for receiving particulate material such as wood particles and adapted to form a pressing zone in which the wood particles are conducted initially in vertical direction and subsequently laterally deflected by 90.degree. along a curved path to form a material strand. The prepress includes two continuous conveyor belts that have upper substantially horizontal belt sections for receiving the particulate material and transporting material webs to the inlet. Extending downstream of the prepress is a main double-belt press for compacting the material strand and for formation of a laminate.

    Abstract: The invention concerns a bonding press for bonding, onto a cloth, a fusible interlining comprising a base fabric associated to one or more thermoadhesive and/or thermocross-linkable adhesive polymer layer(s). According to the invention, the interlining/cloth complex trapped between the two conveyor belts (1, 2) passes through a second area (B) heated to a temperature greater than or equal to the melting temperature of the polymer(s) so as to allow for the chemical coupling reaction of the thermocross-linkable polymers in the interlining's adhesive layer.

  • Patent number: 5640900
    Abstract: A cargo consisting of stacked compressible bales, such as bales of straw, positioned on a flat cargo bed of a cargo vehicle is compacted and compressed laterally of the cargo bed to eliminate excessive overhang of the cargo beyond the sides of the bed by pressing compacting members against opposite sides of the cargo to exert opposing compacting forces on the cargo laterally of the cargo bed. The disclosed compacting members are rollers between which the cargo vehicle is driven in a manner such that the rollers undergo relative rolling movement along the sides of the cargo to progressively compact the cargo from one end to the other.
