摘要:
An apparatus for processing a sample including fibers and trash, having a cylinder rotating in a first direction for receiving the sample. The cylinder has a surface with rigid pins. The pins engage and retain the fibers of the sample. A collection surface receives the trash that falls from the cylinder. A counter-flow of air moves in a separation region between the cylinder and the collection surface in a direction that is substantially perpendicular to and towards the underside of the cylinder. The counter-flow of air has at each position within the separation region an air-flow velocity that is sufficient for the counter-flow of air to blow the fibers that are not originally retained by the pins up toward the cylinder and thereby engaging the fibers with the cylinder, and yet insufficient to prevent gravity from pulling the trash downward through the counter-flow of air.

In a method at a spinning preparation machine, for example a cleaner, opener, carding machine or the like, for cleaning fiber material, especially cotton, an examination of the nature of the trash is carried out, which examination is used for adjustment of at least one adjustable cleaning element, for example a separating blade, cleaning grid or the like.In order to make possible improved and undisrupted production by simple means, the optimum adjustment of the at least one cleaning element for a specific fiber batch is stored in a memory of an electronic control and regulation device and, when the same fiber batch is processed again, the optimum adjustment of the cleaning element is implemented automatically.

An apparatus for detecting a foreign substance in a fiber tuft stream and for separating the foreign substance therefrom. The apparatus includes a conduit guiding the fiber tuft stream therethrough in a conveying direction; an optical sensor system situated at a first location of the conduit for detecting a foreign substance in flight and for emitting signals representing the foreign substance; a separating device situated at a second location of the conduit downstream of the first location as viewed in the conveying direction; an evaluating device for processing the signals; a control device connected to the optical sensor system, the separating device and the evaluating device for operating the separating device; and an opening device situated in the conduit upstream of the optical sensor system as viewed in the conveying direction for opening the fiber tufts prior to passage thereof past the optical sensor system.

An apparatus for sorting fibers and separating them into fractions with desirable and undesirable properties comprises a housing provided with a first chamber; a device for introducing fibers to be sorted into the first chamber; a rotary element revolvably supported in the first chamber and provided with a mechanism for receiving the fibers and applying a fast rotary movement thereto; a multiplicity of material-receiving channels leading from the first chamber, a first one of which is provided with a first window adjacent to the rotary element for the reception of trash of relatively greater mass than the remaining material, a second one of which is provided with a second window for the reception of nep and undesirable fibers of intermediate mass and one of which is provided with a third window adjacent to the rotary element for the reception of desired fibers; the channels being in fluid communication with an air pressure source; wherein the fast rotary movement results in a centrifugal force, which in combination with the degree of air pressure applied in each of the material-receiving channels causes separation of trash of greater mass than the remaining material as well as the separation of nep and undesirable fibers from good quality fibers.

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:
For use with a cotton harvester, a chamber for receiving material from the harvester and a discharge conduit extending from the chamber. A blower for directing air through the conduit and inducing a secondary stream of air in the chamber that picks up the cotton bolls and moves them toward the conduit. A series of rotary-type cleaning blades traversing the chamber above the discharge means from the harvester and on which cotton bolls impinge as they move in the induced secondary stream of air. The blades have peripheral teeth that snag onto the bolls and draw them across an associated grate for removing solid material, twigs and other trash accumulated with the cotton.

The invention includes a method and apparatus for use in wool scouring operations and the treatment of the aqueous scouring liquids after and during use to extract recoverable lanolin or wool grease and heat from such liquids, and separate solid and extraneous matter from the liquids prior to discharge. The method and apparatus provides for removal of excess liquid from wool leaving a main scouring tank, passage of hot liquor and suspended solids from the wool and main scouring tank to a side tank, recycling of liquid from which solids have precipitated and passage of the solids to a heavy solids settling tank via a dump tank, removal of heavy solids precipitated in the settling tank and passage of the remaining liquid through a lanolin extractor; and recycling the remaining liquid or discharging all or part of such remaining liquid to waste via a heat exchanger which recovers heat from the discharge liquid for heating fresh water or liquid.

An object of the present invention is to develop a method of producing pure and long bagworm silk threads comprising no contaminants, such as pieces of leaves and twigs, and a device for implementing the production method.Provided is a method of producing a long bagworm silk thread, the method comprising a spinning process of making a bagworm having its nest hang its legs on a rail and continuously spin a silk thread along the rail, wherein the rail has a width smaller than the maximum width between the left and right legs when the bagworm used spreads out its legs and wherein the rail is such that the bagworm can hang its legs on the rail, and a collection process of collecting a long silk thread from the rail after the spinning process.

A device is provided for separating out foreign particles and/or neps in a pre-carding zone and/or a post-carding zone of a carding machine having a carding cylinder. The device has at least two modules arranged opposite the carding cylinder in the pre-carding zone and/or the post-carding zone. Each module has a plurality of operating elements, the elements being arranged beside one another as seen in a circumferential direction of the cylinder. The operating elements are fixed carding elements, suctioning devices, and/or separating knives.
