- ments in Carding Machines, of which the following, taken in connection with the accompanying drawings, is a full,' clear, and exact description.
My invention relates to an apparatus for the manufacture of rovings from asbestosor other flocculent fibre and it has for its object to provide an Improved construction of a carding machine whereby such rov1ngs may be produced in-a practical, efficient and Y inexpensive manner. Owing to the lack of sufficient tensile strength in fibres of flocculent material to withstand alone the necessary operations to form them into rovings or yarns it is customary to make a combination with a supporting or core yarn of cotton or other material to give this additional strength.
My invention consists of the novel means and arrangement of parts of a carding ma- -chine for producing rovings, which will be hereinafter fully described and pointed out in the claim.
In the accompanying drawings Figure 1 is a sectional elevation ofthe delivery end of a finisher carding machine showing my improvements together with the condenser and roving spool winding means the framing of the card and supports of the con denser rolls being omitted. plan view of Figure 1. Figure 3. is a, slde elevation showing the driving means of my improvements. Figures 4 and 5 are longitudinal sectional views of the sliver supporting roll and core thread guiding rollrespectively.
In carrying out my invention I make use of a finisher carding machine comprising a main carding cylinder 1 of usual construction provided with card clothing from which the carded sliver is taken off by a doffer 2 of extra large diameter provided with either a series of rings of card clothing 3 separated by narrow rings of leather 01' other smooth material or as an alternative construction I prefer to make use of narrow strips of thin polished steel 4 fastened at one end to a stationary rod 5 supported by brackets 6 fixed to the card sides 7. The steel strips superimpmed on the surface of n Figure 2 1s a the doffer extend below the contact point of the dofl'er and cylinder and are held in position by weights 8. By this-construction the surface of the dolfer at point of contact with cylinder presents alternate spaces of card clothing and dividing strips by means of which the sliver is deposited in strips on the dolfer and is removed therefrom by the action of an oscillating comb 9 of well known construction. As the sliver delivered by the comb is lacking in tensile strength sufficient to withstand subsequent operations I provide additional strength to each strip of sliver by means of a core thread 10 of cotton, or other material. These threads are drawn by the action of rub rolls 11 and 12 over a guide roll 13 and a sliver supporting roll 14 each provided with annular grooves, the center lines of which coincide with the center line of the spaces of card clothing on the doffer. Therolls 13 and 14 revolve in bearings (not shown in drawings) fixed to the card sides. Rotary motion is imparted to the rub rolls and grooved rolls by suitable gearing t'rom the doffer, which is driven in the usual manner from the cylinder. The guide roll 13 is so placed that each sliver as it is combed from the dofi'er falls onto its respective supporting thread and being supported thereby passes into the 'rub aprons 15 of usual construction where the sliver and thread are agglomerating together into a common mass in the form of a roving and wound on a spool 16 in frictional contact with the drum 17 which has a rotary motion imparted by a train of gears from the doifer gear 18, driving pulley 19, belt 20 and driven pulley 21 on shaft of drum 17.
I am unaware thatanyonehas ever made use of a pair of annular grooved rolls such as I have adopted. for carrying the sliver and its supporting thread. in machines for forming rovings from flocculent material. In carrying this part of my invention into effect I find the best results are obtained by forming the annular grooves in ions 13 and H with wide openings and rounded bottoms of a diameter less than the width of the strip of sliver. This construction tends to more thoroughly consolidate the sliver and its supporting thread together before being acted on by the condenser.
'hat I claim is In a finisher carding machine having means whereby the sliver delivered from the dofi'er in narrow strips, the combination with said means of a supporting thread for each strip of sliver, a roll provided with an annular groove for each sup-porting thread, a second annular grooved roll for consolidating each sliver and its supporting thread, condenser rub-aprons for ag- 1,444,ese
glomerating each thread and its sliver into a roving and means for operatively actuating the mechanism.
In testimony whereof, I have Signed this specification.
