PA ENT OFFICE OPENING AND CLEANING OF TEXTILE FIBERS Application September 22, 1937, Serial No. 165,028
In Germanyv October 2, 1936 v 6 Claims. (01. 19-30) The invention relates to the opening and cleaning of textile fibers in the form of tow, ground straw and the like, its object being to effeet the treatment with a minimum of waste and a minimum of damage to the fiber,
The invention consists in subjecting the fiber inthe form of a band or lap to a series of known operations, namely breaking, condensing, zig-zag passage through a series of ribbed rolls with si-] multaneous action 01' a ribbed drum on the lap,
through a series of ribbed rolls; with a ribbed drum acting on the lap, a second attenuation of the lap, and finally beater action, all these operations, insofar as they involve pressure on the lap, being performed by means of elastically mounted appliances or with the lap resting on an elastically mounted support.
An example of apparatus according to the invention is shown in the accompanying drawing, in which Fig. 1 is a longitudinal section thereof, and
Fig. 2 is an elevation, to a much larger scale, of a portion of one 01 the appliances.
The drawing illustrates the treatment of a wide band W of tow, which passes through successive stages marked by the letters A to G in Fig. 1.
At A there is a series of breaking rolls I, 2, the rolls I having teeth or, spikes, and being driven, and the rolls 2 being of rubber, and not being driven. The fiber at this stage is still very rough, and it is fed in in the form of a fairly thin band. At B the band or lap is condensed, due to a reduction in the rate at which it travels through the next stage C. i
For the treatment at C there is a driven shaft 3 having thereon a drum. 4 with longitudinal ribs 5 consisting oi. L-bars resting upon elastic rings or, belts 6 of rubber or equivalent material surrounding the drum. Instead of using a cylinder the drum may consist only of two discs or heads with the belts 6 thereon, supporting the ends of the bars. Around a portion of the circumference of the drum there is an arcuate series of longitudinally ribbed rolls 1, the bearings 01 which are slidablein arcuate'guideways la, the rolls being however normally held in mesh with each other by coiled springs 8 acting on the bearings or the rolls at the ends oi! the series. Outside the arcuate series of rolls 1 there is an endless travelling apron 9;
The lap condensed at B is gripped by the rolls I and takes a zig-zag course through the series. In the course of its travel it is repeatedly acted on by the ribs 5, which sweep away particles of wood coming to the surface of the lap. As the ribs 5 rest on elastic beds, and the rolls 1 are able to yield elastically, both forwards and rearwards, the lap can be pressed firmly against the ribs without risk of damage to the machine or to the fiber.
After leaving the last roll I the lap travels at D down an inclined plate i0, onwhich it undergoes some attenuation or stretching for the purpose of straightening out knots, if present, the stretch being due to the higher velocity at which the lap travels through the next stage E. The appliances at this stage E are precisely similar to these at stage C, except that the rolls 1 are below the drum, instead of above it.
Fromthe second series of rolls 1 the lap is fed on to a curved plate I l, which is hinged at I2 and rests upon a coiled spring H. A driven roller i3 bearson the lap travelling on the plate, and is driven at a speed whereby some further attenuation is eifected.
The delivery end of the plate H, where the lap leaves it to enter upon stage G, is downwardly curved, and at this part a rotary beater l6 acts on the lap, opening-itand drawing out the longer fibers. Damage to the fibers is prevented by the elastic mounting of the plate H.
The lap drops from the plate I! on to a spiked conveyor ll whereby it is fed out of the machine, and while travelling thereon it is acted on by a seriesof rakes l8 suspended from pivots above the conveyor.
through a series of elastically mounted ribbed rolls and simultaneously subjecting it to the action of elastically supported heaters, attenuating the lap, passing it through another series of elastically mounted ribbed rolls and simultaneously subjecting it to the action of elastically supported heaters, again attenuating it, and then subjecting it while elastically supported to beater action.
