    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： An apparatus and method for measuring characteristics of entities in a sample of textile material, including trash, provides a sample of textile material to a processor where entities are individualized and thereafter transported to a sensor system. Characteristic signals are generated by the sensor signal corresponding to sensed characteristics of the entities, including trash, and a computer analyzes the characteristic signals to identify signals corresponding to trash and to classify the trash signals as corresponding to one of several types of trash. Based on the characteristic signals, the computer determines an entity length, diameter and speed and also determines a peak value of a characteristic signal corresponding to an entity. Based on these measurements, trash is characterized as to one of several types of trash.

    摘要： Single entities such as fibers are delivered one at a time to a fluid stream, and a nozzle orients the entities so that each entity along its length (major dimension) is generally parallel with the direction of fluid flow. The entity then enters a sample region and a sensor senses entity data such as the speed of the entity as it passes through the sample region. A preferred embodiment includes a collimated beam of light and two side-by-side photo detectors positioned to measure light extinction caused by fibers passing through the sample region. Another sensor may be provided to detect light scattered forward at an angle of about forty degrees (40.degree.). The sensor signals are used to generate data that corresponds to such parameters as length, fiber ribbon width, fineness, cross-sectional area, maturity, cross-sectional circularity, shape, surface roughness, etc. Optical filtering provides information about composition (natural or man-made) and appearance (color and polarization).

    摘要： A map maker is disclosed in which a physical map is produced by depositing fluid entrained entities, such as cotton fibers, trash and neps, in a pattern on a surface, such as a nylon mesh surface. Each position in the pattern is uniquely associated with data produced by another monitor to provide topological mapping between the data event map and the physical map. In one embodiment, a drive system and computer are used to control the position of a surface relative to a nozzle that deposits the entities on the surface and relative to a camera that scans the map formed on the surface. In the preferred embodiment, the map is planar, but an alternate cylindrical map is shown. Also, an embodiment is shown in which a map maker is incorporated into a carding machine.

    摘要： An apparatus for testing fibers includes a single fiber preparation and separation device for separating fibers from a sample of multiple fibers and producing an output of single fibers. A fiber transport means, preferably an air conduit, receives the single fibers and transports them to a removed location where at least one fiber is sampled from the transport means. In the preferred embodiment, the sampler is a hook that is inserted into, and removed from, an air conduit to hook and remove single fibers carried in a stream of air inside the air conduit. A testing apparatus associated with the sampler then determines at least one characteristic of the sampled fiber, such as strength, tension as a function of elongation, or cross sectional characteristics.
