tow It inputs pressing to feed pressing, has the short fine long filament of twirl by what is be made of twirl staple fiber aggregate and mono filament or non-twist endless tow Aggregate is covered between the upper outer roller set of input upper roller that closely pressing is common feeds by the lower outer roller of the input lower roll of input pressing pair Enter, then by closely pressing is common defeated between the lower outer roller set of the output lower roll of output pressing pair and the upper outer roller set of output upper roller Out, the short fine long filament aggregate of backtwisting is made, during this, the second motor drives twist band along left fast pulley and right fixed repeating query Ring rotation has the top for twisting the upper side band that short fine long filament aggregate first passes through twist band, is having the short fine long filament set of twirl at this time Upper contact point is generated between body and upper side band, and is had to twist at upper contact point and generated one between short fine long filament aggregate and upper side band Fixed upper tension, and the size of upper tension is pressed to it with input pressing with output by the line between upper side band and lower sideband Between the angle of line determine, upper side band rotation then at the upper contact point to have twist in short fine long filament aggregate have it is certain The staple fiber aggregate of the twist generates friction force, to twist staple fiber aggregate under the drive of friction force and produce to having Raw backtwisting twist effect, and the size of the backtwisting twist is determined by upper tension, the orientation of the backtwisting twist and has twirl staple fiber aggregate The orientation of the twist of itself is on the contrary, and to twist in short fine long filament aggregate be the smooth mono filament in surface or non-twist length due to having Tow, so that upper side band rotation is then at upper contact point to the mono filament having in the short fine long filament aggregate of twirl or without the length of lay The small friction force that tow generates, and the small friction force be only capable of driving mono filament or non-twist endless tow along The first small transverse shifting occurs for the direction of upper side band rotation, and the backtwisting twist passes up and down respectively along upper contact point It passs, during being communicated up, is transmitted between along there is twirl staple fiber aggregate to press in upper contact point and input, thus There is twirl staple fiber aggregate to generate backtwisting effect, the obtained short fibre of backtwisting to being located at upper contact point and inputting to press between between Aggregate is tieed up, is become loosely so that having and twisting staple fiber aggregate, due to there is the rear end for twisting staple fiber set to be entered pressing To close pressing, so that thering is the loosening degree for twisting staple fiber aggregate first to increase in direction toward input pressing along upper contact point Reduce after adding, divides so that being gradually located at first along input pressing to up contact point direction mono filament or non-twist endless tow It in scattered staple fiber aggregate, is then swept along wherein by the staple fiber aggregate that degree of scatter is gradually reduced again, thus finally By the short fine long filament aggregate of upper contact point output backtwisting, and due at this time mono filament or non-twist endless tow turn along upper side band The first small transverse shifting occurs for dynamic direction so that by the short fine long filament aggregate of the backtwisting in output, long filament or Non-twist endless tow is located at the position slightly to the left or to the right of the short fine long filament aggregate of backtwisting, and the short fine long filament aggregate of backtwisting is then Across the top of the lower sideband of twist band, contact point under being generated between the short fine long filament aggregate of backtwisting and lower sideband at this time, and Certain lower tension is generated between the short fine long filament aggregate of backtwisting and lower sideband at lower contact point, and the size of lower tension is by upper Line and input between sideband and lower sideband press to and export the angle decision of line of the pressing between, lower sideband rotation Then friction is generated to the staple fiber aggregate with certain twist having in the short fine long filament aggregate of twirl at lower contact point to make Firmly, thus under the drive of friction force to have twist staple fiber aggregate generate first twisting the twist effect, and first plus The size of the twirl twist is determined by lower tension, first twists the orientation of the twist and the twist for having twirl staple fiber aggregate itself of feeding Orientation it is identical, and due to being the smooth mono filament in surface or non-twist endless tow in the short fine long filament aggregate of backtwisting, thus So that then the mono filament at upper contact point to backtwisting in short fibre long filament aggregate or non-twist endless tow generate for lower sideband rotation Small friction force, and the small friction force is only capable of that mono filament or non-twist endless tow is driven to turn along lower sideband The second small transverse shifting occurs for dynamic direction, and the second transverse shifting is contrary with the first transverse shifting, so that In the short fine long filament aggregate of backtwisting, long filament or non-twist endless tow are located at the intermediate position of the short fibre long filament aggregate of backtwisting, and first The twisting twist is transmitted along lower contact point up and down respectively, the first twisting twist be communicated up during with transmit downwards The backtwisting twist mutually converge and the orientation of the two on the contrary, when first twisting twist size be equal to the backtwisting twist size when, in upper side band There is no twist effect between lower sideband, so that the short fine long filament aggregate of the backtwisting between upper side band and lower sideband is in flat Steady transition stage has solution when the first twisting twist is sized to be slightly smaller than backtwisting twist size between upper side band and lower sideband Twist effect is twisted, so that the short fine long filament aggregate of the backtwisting between upper side band and lower sideband continues backtwisting effect, from And make backtwisting staple fiber aggregate continue backtwisting and become loose, so that mono filament or non-twist endless tow are in more Add in loose backtwisting staple fiber aggregate, when the first twisting twist size is slightly larger than backtwisting twist size, in upper side band and There is micro- twisting twist effect between lower sideband so that the short fibre long filament aggregate of backtwisting between upper side band and lower sideband into Row micro- twisting effect again, so that backtwisting staple fiber aggregate carries out micro- twisting and becomes compact, so that mono filament Or non-twist endless tow is in and is swept along by backtwisting staple fiber aggregate progress one, in downward transmittance process, along backtwisting staple fiber collection Zoarium is transmitted between in lower contact point and output pressing, thus to the solution of lower contact point and output pressing between is located at It twists staple fiber aggregate and generates twisting effect, the first twisting staple fiber aggregate is made, so that backtwisting staple fiber aggregate Become consolidation, since the front end of backtwisting staple fiber set is pressed by output pressing close, so that past along lower contact point Output pressing gradually increases the consolidation degree of direction backtwisting staple fiber aggregate, so that pressing
