摘要： Disclosed are various needle-based devices for individualizing single fibers and other entities from a fibrous mass, particularly for testing purposes. In one embodiment, an accelerated pin drafting machine has a plurality of combing elements which sequentially pierce a fiber mat and move within a drafting zone with increasing distance between adjacent combing elements. The accelerated pin drafting machine in turn feeds a fiber individualizer. In another embodiment, a comb-like needle sampler is provided which moves past a perforated plate such that portions of fibrous material protruding through the perforations are loaded onto the needle sampler. An elastomer clamping feedroll moves against the needles to clamp the sample, and then rotates to gradually feed fibers from the sampler. As an alternative to the elastomer clamping feedroll, a clamping block presses against the needles, and the needles are slowly retracted to gradually release fibers. In a third embodiment, fibers protruding through a perforated plate are loaded onto a single needle, and the ends of the fibers are drawn into an airstream moving through a passage defined by a housing on either side of a fiber plate. The fiber plate subsequently engages the needle to clamp fibers in position and the housing retracts to expose the fiber plate for fiber preparation. Thereafter, a roll or apron feeds individual fibers from the fiber plate.

摘要： A method for producing multiple fiber data from a plurality of single fiber tests. A plurality of individual fibers are subjected to tension tests such that the individual fibers are elongated tensioned and broken while characteristics of the fiber are monitored. Multiple fiber data are obtained by testing a number of fibers from a sample and superimposing the graphical representation of tensile characteristics of the individual fibers upon one another to obtain a composite representation which constitutes multiple fiber data. Characteristics of individual fibers which may be combined to obtain a composite representation constituting multiple fiber data include such characteristics as tension, elongation and cross-sectional characteristics of the fiber.

摘要： Conditioned gas flows are applied at various critical locations in instruments and apparatus for testing and processing textile fibers, such as cotton. In the context of test instruments, a standard test zone environment (which becomes part of the test record) is effected by the introduction of controlled conditioned gas flows directly into a testing zone, including into testing instruments themselves. In the context of processing apparatus, direct control of processing performance parameters is effected by "controlling parameters", which are in turn effected by the application of conditioned gas flows. A plurality of "performance parameters", which may be in conflict with each other, may be controlled in accordance with a predetermined compromise control strategy, carried out by feedback or feedforward control systems implementing modern statistical control approaches.

摘要： An apparatus for monitoring trash in a sample of trash particles and fibers includes scales for determining the weight of the sample which is transmitted to a computer. The sample is presented to a sensing volume and an optical sensor produces an output signal corresponding at least to the presence of the trash particle in the sensing volume. In one embodiment, the output signal is the waveform corresponding to light extinction caused by the presence of the particle in the sensing volume. In a second embodiment, image analysis of trash particles in a sensing volume provide output signals corresponding to the size, shape or composition of the particles. The computer receives the weight data and the output signal from the optical sensor and produces output data in the form of a count of at least a portion of the trash particles per unit weight of sample. The computer also outputs data in the form of or corresponding to the effective diameter, projected area and weight of the trash particles and count and weight of the fibers. In particular, the computer categorizes trash particles and outputs data for a particular category of particles.

摘要： A fiber testing apparatus includes two support members for holding a fiber and a positioning mechanism to facilitate placement of the fiber into engagement with the support members. A translation apparatus moves the two support members apart while a monitor records at least one characteristic of the fiber as it is tensioned. In one embodiment, the two support members are first and second clamps and the positioning apparatus includes first and second suctions oriented to draw the fiber in opposite directions and place the fiber in a substantially linear configuration adjacent to both clamps. In another embodiment, a hook and clamp configuration is utilized, and in yet another embodiment a vacuum groove is employed to facilitate positioning of the fiber.
