The invention discloses a purlin production device for the weaving industry, which includes a production box, wherein the production box is provided with a production space, and a bottom space of the production space is provided with a scraper space connected to the production space. The knife holder is slidably installed in the scraper space. When the bamboo strip is fed into the production space, the first motor is started. The first motor drives the first pulley to rotate, and the first pulley rotates to rotate the first transfer cylinder. A conveyer transfers bamboo slivers to the left, and can automatically make slivers. By simulating the way of making slivers by hand, the efficiency of slivers production can be greatly improved, and the quality of slivers can be improved. Different tools can be used Dividing the purlins can make different purlins, and the burrs of the bamboo can be removed first.

An apparatus with a projection defining first and second openings and a channel between the openings. An interior surface adjacent the channel tapers inwardly from the first opening to the second opening, and a shearing edge is positioned adjacent the second opening. A method of using the apparatus to separate protuberances of a plant from an elongate portion of the plant by pulling the elongate portion through the channel. Another apparatus with first and second counter-rotating rollers. Each roller having alternating projecting portions and valleys and oriented so that projecting portions of one roller are aligned with valleys of the other roller as the rollers rotate. A method of using the rollers to deform an elongate portion of a plant between the projecting portions of one roller and the valleys of the other roller.

A decortication system includes a feeder configured to convey unoriented fiber-bearing plant stalks in a bulk mass and a decorticator assembly comprising a multi-stage decorticator assembly. The decorticator assembly includes at least a first stage decorticator and a second stage decorticator arranged in series with one another. The first stage decorticator comprises a ripper that is configured to separate stalks from the bulk mass delivered by the feeder and to meter movement of stalks away from the ripper. The second stage decorticator is located downstream of the ripper and further decorticates the stalks to produce fiber and hurd that are separated from one another. It may comprise a roller-roller breaker assembly comprising plurality of roller-breaker assemblies located in series with one another. A third stage decorticator may be located downstream of the second stage decorticator and may comprise a second roller-breaker assembly.

The present invention relates to a method of producing a ribbon comprising bamboo fibers. The method comprises positioning the fibers on a conveyor and conveying the fibers in a transport direction, interconnecting the fibers by covering the fibers with thread and/or particles of a sticky material with at least one web forming device which is positioned above and/or below the conveyor and which ejects thread and/or particles. The formed thread and/or particles attaches to the fibers and forms a web which interconnects the fibers in order to form the ribbon and/or stitching the fibres together with at least one stitching device which is configured to stitch the individual fibers together in order to form the ribbon.

A method for processing bast fibers includes orienting the bast fibers substantially parallel to one another; and feeding the bast fibers into a roller system to at least one of bend and break stems of the bast fibers. The roller system includes a first roller including a first plurality of teeth and a second roller including a second plurality of teeth having a span distance. The first roller and the second roller are arranged such that each of the first plurality of teeth passes between adjacent pairs of the second plurality of teeth. The first plurality of teeth of the first roller and the second plurality of teeth of the second roller are configured to load the stems of the bast fibers in a shear mode to at least one of bend and break the stems.

A decorticating machine comprising modular drum assemblies of different tooth and surface patterns that are installed between pairs of left and right lower and upper rails is described. The modular drum assemblies (usually provided in upper and lower drum pairs) and the number thereof can be chosen based on the particulars of the type of stalk being processed.
