rnoonss ron THE PRODUCTION or aovme rnorr COTTON Ann SIMILAR FIBROUS MATERIAL.
Application filed July 25, 1925, Serial lie 46,166, and in Germany August 6, 1924.
In the manufacture of textile yarn one of the first steps is to produce a sliver which is subsequently spun upon suitable spinning machinery to form the finished yarn. Various systems of spinning the sliver are employed, varying in accordance withthe kind of fiber, for example cotton or wool, and the fineness of the yarn desired, the machinery employed being varied accordingly.
In one common system ofspinning fine numbers of cotton yarns the fiber is first carded upon revolving flat cards. The sliver thus produced is then .drawn in.a drawing frame and after this first drawing the sliver is subsequently furtherdrawn in passing through a series of roving and spinning frames. I
For manufacturing coarse numbers of cotton and woolen yarns the fibers are frequent- 1y carded ona series of roller cards (usually three) and the fiber is then delivered directly to a tape condenser which forms it into roving, the independent drawing step being omitted. This roving is then delivered directly to spinning mules or ring frames where it receives but slight drawing and is spun directly into yarn but. it is not possible by this latter system to obtain fine counts of yarn for the reason that, there is but little draw introduced during the process and the roller cards do not lay the fibers nearly so parallel as the flat cards.
In accordance with the present invention I I employ a system combining steps from the two systems just referred to and in practls ng this new process prefer to employ machlnery such as is used in each of said processes. Bythis combined process I am able to produce a fine roving whose fibers are generally parallel and which can besubjected to a relatively high draw in spinning. These results I obtain by carding. the fiber upon a single revolving flat card and delivering the product of this one carding operation directly to a tape condenser. The single flat card thus employed takes the place of two orthree roller cards employed in the coarse yarn process and lays the fibers much more nearly parallel than results from'the use of a plurality of roller cards. The roving delivered by the tape condenser can now be finely spun although perhaps not to the highest numbers, but nevertheless can be made into yarns sufliciently fine' for many purposes, while the process is much simpler than the usual process of making fine numbers and the machinery employed 'is less expensive and occupies less floor space than the machinery employed in. either of the prior proces es.
In the accompanying drawings Fig. 1 is a diagrammatic side elevation illustrating the combination of a revolving fiat card with a' tape condenser; and
Fig. 2 is a diagrammatic side elevation illustrating the combination of a half-flat half-roller card with a tape condenser.
In Fig. 1 the numeral-ldesignates a lap roll resulting from the operation of a picker,
lapper or other machine preliminary to the carding operation, it being understood that this lap constitutes a convenient but. not
and delivers the fiber in the form of a fleece to a tape condenser 4 of the kind commonly used in the coarse cotton or woolen system. This tape condenser divides the fleece into a plurality .of rovings, which are of so uniform character that they may be delivered directly to a spinning mule or ring frame and spun into yarn of a satisfactory char acter.
In Fig. 2 I have illustrated a preferred arrangement in which the lap roll 1", the card feeder 2, and the tape condenser 4. may be similar to the parts 1, 2 and 4: above described. but in this instance the card 5 is a half-flat half-roller or union card, which I find. unites the high productive capacity of the roller card with the accuracy and dependability of the flat card, and yields a clean uniform fleece whose fibers are nearly parallel and well adapted for division by the tape condenser into a plurality of rovings of suitable character for spinning.
While I have specifically referred to cotton as the fiber employed, I wish it to be understood that my present process and apparatus is equally applicable to fiber of a character similar to cotton, for example cottonized flax, hemp and china-grass waste.
