摘要:
Device for mechanically splitting finite textile fiber bundles, comprising n individual fibers (n≧2) in fiber bundles having less than n individual fibers and/or individual fibers, characterized in that in a milling chamber that is closed off from the outside and that has one or more dead spaces of at least 10% of the milling chamber volume and in which one or more rotating striking elements operate in a non-cutting manner and so as to reduce load peaks and at a rotational speed that can be adapted to the material but that is at least 200 r.p.m., the material is adjustably input in different amounts in batches, treated for an adjustable duration, and then discharged again from the milling chamber.

A method and apparatus is provided for the processing of polypropylene fiber from polypropylene twine. The material may be produced from feedstock after its first instance of usage. The feedstock may have residual contamination resultant from its first instance of usage. The method is provided to collect feedstock in skeins, sever the skeins into bundles, wash, disinfect and pH neutralize the surface of the feedstock, cut to length and reduce the feedstock to a fibrous clean, dry state suitable for use as a reinforcement or additive to composite material.

An ejection nozzle for transport of fiber thread pieces by means of compressed air, e.g. reinforcement material for manufacturing fibre reinforced plastic products, from a cutter to a moulding cavity. The nozzle is provided with a common flow duct for the compressed air and the fibre thread pieces. The flow duct runs past at least one reflector surface (15) for the air flow, and at least one opening (16) for evacuation of air to the surroundings is located along the flow duct.

Cotton linter pills, produced by the processing of cotton seed at an oil mill, are fed in blanket formation into a roller assembly wherein an attenuating roll and a diffuser roll act thereon to untangle them and separate fibers from trash with the diffuser roll propelling the fibers and trash into a sealed plenum chamber below a high speed air stream of a closed air circuit entering the chamber so that the heavy trash falls into a discharge means in the low pressure area under the air stream with the fiber stream being caught up and carried by the air stream impinging therewith on the lower end portion of an upwardly inclined rocking and vibrating, perforated diaphragm in the chamber so that the longest free fibers rise with the bounce of the air stream off the diaphragm into the upper expanse of the chamber and the shorter fibers, linter fines and light trash move up the diaphragm that acts to siftingly discharge the linter fines and lighter trash downwardly therethrough into an underlying low pressure area collection means. The cleaned long fibers and cleaned short fibers are separately collected by collector and condenser units at the upper end of the diaphragm adjacent the top of the chamber and discharged from the chamber in separate long fiber and short fiber mats, such units operating under vacuum produced by the return line of the air circuit and a retention means being provided in the return line, downstream from such units, for collecting sheeted cellulose fines.

An adjustable lever arm extension for use on hand tools that employ an operating lever to apply force in operation of the tool. The extension is pivoted near the extremity of the operating lever, and has a grip that releases under predetermined force to permit the extension to pivot freely after that force has been reached. This limits the maximum amount of operating force applied by the tool.
