Lorig, Ross Township, Allegheny County, Pa., assignor to United States Steel Company, a. corporation of New Jersey Application August 5, 1949, Serial No. 108,821
This invention relates to apparatu for continuously abrading an elongated strand and more particularly to such apparatus for abrading the surface of a narrow strip slit from wide hot rolled coils. Th strip in the coils hasa, crown across its Width so that they are thicker in th center than on the edges. If the strip is pickled, cold reduced, and slit, the center slit coils are thicker in gage than those secured from the edges because the cold rolling merely reduces and does not eliminate the crown. Furthermore, the edges of th slit strip are slightly thicker on one edge than on the other. The strip also varies in gage from its leading to trailing edge and thisvariation is not always uniformly removed in the cold rolling process. The edges of the slit coils are often rough and have sharp burrs thereon. In order to produce a smooth narrow strip of uniform cross section, it is necessary to grind the surface of the strip. At present this is not feasible for many reasons. Any means presently available is relatively slow and there is danger of damage to the strip due to excessive heating.
It is therefore an object of my invention to provide apparatus for continuously abrading strip in which the danger of overheating the strip is greatly reduced.
It is another object to provide such apparatus at which the abrading is done at a high speed.
These and other objects Will be more apparent after referring 'to the following description and attached drawings, in which:
Figure 1 is a schematic view of one species of the apparatus;
Figure 2 is a top plan view of Figure 1;
Figure 3 is a schematic view of a second species of my invention;
Figure 4 is a top plan view of Figure 3;
Figure 5 is a plan view of a third embodiment of my invention;
Figure 6 is a side view of Figure 5;
Figure '7 is a schematic view of a fourth embodiment; and
Figure 8 is a top plan view of Figure '7.
Referring more particularly to Figures 1 and 2 of the drawings, the reference numeral 2 indicates a continuous strand helical conveying reel such as is shown in my copending applications, Serial No. 80,673, filed March 10, 1949, Serial No. 85,699, filed April 5, 1949, which issued as Patent No. 2,589,411 on March 18, 1952, and Serial No. 86,375, filed April 18, 1949 which issued as Patent No. 2,576,233 on November 27, 1951. A rotatable roll 4 is spaced from the reel 2 and has its axis substantially parallel to the axis of the reel. An
6 Claims. (Cl. 51-74) abrading wheel or belt 6 is arranged adjacent the roll 4 and is movable to and from the roll. The abrading wheel 6 may be a grinding wheel, wire brush, bufier, or a combination thereof. The strip S to be smoothed passes from an uncoiler, not shown, to the helical conveying reel 2, thence to the roll 4, back to the reel 2 and is gradually moved across the surface of the reel in the mannermore fully disclosed in my aforesaid copending applications and then leaves the reel, as shown by the arrow in Figure 1. If desired, the strip S can enter and leave thev apparatus as shown in broken lines in Figure 1. It will be seen that as each convolution moves across the face of the roll 4, it will be contacted by the abrading wheel 6. If a combination wheel is used, the initial operation may be a rough grinding and the final operation a bufing operation. It is apparent that each increment of surface of the strand S will receive the same surface treatment. Since no portion of the strip S is in contact with the abrading wheel 6 for any substantial length of time, there will be no danger of the strip overheating.
The apparatus shown in Figures 1 and 2 will only smooth one sid of the strip, but. if desired, two such units can be connected in tandem and the strip directed from one to the other in such a manner that the two sides of the strips are successively smoothed.
The apparatus shown in Figures 3 and 4 is quite similar to that shown in Figures 1 and 2 except that it is arranged to smooth both surfaces of the strip being processed. As shown in Figure 3, the strip S passes from the uncoiler 8, around the guide roll [0, to the continuous strand helical conveying reel [2 and then around the guide roll M to a rubber or belt back-up roll 16. A roll l8, similar to roll I6, is spaced a short distance from roll 16, the strip passing between and around the rolls in such a manner that the side of the strip contacting the roll [6 will be on the outside as it passes around the roll l8. From the roll IS the strip passes around guide rolls 20 and 22 and back to the reel l2. The strip moves across the face of the reel I2 in the same manner as it does across the face of the reel 2 until it reaches the end thereof opposite the uncoiler 8. From here the strip passes to the coiler 24. Abrading wheels 26 and 28 are provided adjacent the back-up rolls i6 and I8, respectively, and function in the sam manner as abrading wheel 6.
Figures 5and 6 show a third embodiment of myinvention which is particularly adapted for finishing the surface of an endless elongated strand forming a band B. This apparatus consists of a continuous strand helical conveying reel 26, back-up roll 28 and an abrading wheel 30, all of which function in the same manner as in Figure 1. In addition, there is provided a pair of spaced apart rolls 32 arranged with their axes at an angle to the reel 26. Between the rolls 32 is a strand twister 34, which turns the strip over. The elongated strip is passed around the reel 26 and roll 28 in the direction of the arrows and is delivered from the right hand end of the reel as shown in Figure 5 to the right hand roll 32, thence through the strand twister 34 and around the left hand roll 32. The strand is then cut and the two ends of the strand passing through the apparatus are fastened together to form an endless band B. The reel 26 is then rotated and the surface of the band Bis moved in the same manner as in the first embodiment. Due to the twisting of the band B both sides thereof are smoothed in alternate passes through the apparatus. The number of passes may be varied as desired.
Figures 7 and 8 disclose another embodiment of my invention which is quite similar to that of Figures 5 and 6. In this embodiment, a continuous strand helical conveying reel 26, back-up roll 28, and abrading reel are provided in the same relationship as in Figure 6. However, the apparatus is otherwise varied in order to provide for the processing of a much longer strand. In this apparatus, the strip of band B, leaving the reel 26, passes over guide rolls 36 and 38 and around a reel 40, which is similar to reel 26. From here the strip in the band B may pass over a guide roll 42 to the band twister 44 and thence over the guide roll 46 and back to the reel 26. However, as shown in the drawings, in order to have a still greater amount of strip in the band B, the strip before passing over the guide roll 42, passes around guide rolls 48 to a continuous strand helical conveying reel 50 and around the guide rolls 52 and back to the reel 40.
While four embodiments of my invention have been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
