This invention relates to a method and means of re-flutin textile rolls and the like so as to provide said rolls with new flutes and place them in as good, or better, condition. as when new.

An object of this invention is to provide means for rendering textile rolls, which have become worn, capable of use by re-fluting the same and re-allocating the surface thereof and building up the flutes again to their original condition. I r V r 7 Another object of this invention is to provide a method and means of re-fluting all types of textile rolls by imparting to the surface thereof flutes in all respect, as good as, if not better, than the original surface when the rolls were new.

It iswell known that fluted rolls, when they become worn, cannot be re-fluted by merely passing a file or stationary cutter along I the old grooves, as this will produce a roll of less cross-sectional area than a new, roll. This invention, by employing a revoluble cut-v ting tool, does not remove any portion of the metal from the roll, but displaces the same and forces it radially outward and builds up the flutes to their original cross-sectionalarea, providing rolls equally as good as new.

The rolling and cutting members for re forming the flutes are chosen to fit the particular shape of the old groove many particular roll, and in many instances, these rolling and cutting members must be ground to as to reform the flute without breaking the .metal. Also it might be'noted that another advantage of the method and means herein employed, is that it is a cold rolled process so that low places in a portion of the old rolls will be built up to a thickness corresponding to the remaining portion of the roll for the reason that a certain amount of themetalis pushed longitudinally of the roll a short distance by the rolling and cutting tools while at the same time being pressed laterally and seeking a place in which to be deposited,and in this manner a flute having a smooth sidewall is provided which is free from burrs to through the cutting tool; the proper shape so as to be suitablefor a particular groove in a particular type oftextile roll soas to fit the groove in such a manner a much greater extent that: are the grooves formed by filing or" cutting; by means of a stationarycutting tool. Also it is'well known thatby building flutes in this manner that the molecules are packed together forming a flute whichlis more resistant to wear than one which is formed by cutting by a file or a stationary cutter; Thus, it is seen by the method employed that a roll may here-fluted and put in a better condition than a new roll.

By means of this process, a smoother flute is provided which causes the yarn or other fiber passing between the rolls to clear the rolls much better than ifnew rolls made by filing .or cutting the flutes with a stationary cutter were used. One method heretofore employed. in cutting grooves has vbeen a posi tlvely driven rotary cutter which acts in a 'manner as'above described but leaving a rough surface to the sidewalls of the flutes.

Some of the objects ofthe invention'hav- :ing beenstated, other objects will appear as the description proceeds when taken in ings, in which- 7 V Figure 1 is a sideelevation of one form of the mechanism which may be used in refluting therolls; y Figure 2 is a plan view of'Figure 1; r F igure 3 is a transverse cross-sectional view taken along the line 33 in Figure 2; Figure 4' is a cross-sectional view taken connection with the accompanying draw,-

taken Referring more particularly to the drawings, the numerals 10 and 11 indicate'suitable supports vfora table 9 which has members 12 and 13 secured thereon, said members 12 and 1.3 having upstanding end por- V tions Hand l5 and the central stud supporting portions 16 and 17 which have studs18 and 19 therein on which are pivotally mounted arms 20 and 21 which are joined together by means of a rod 22 being secured by means of stud bolts 23 and 24, and the other end of said members and 21 have secured therein a square rod 25 by means of stud bolts 26 and 27, and on this rod 25 are adjustably mounted holding members 28 and 29, each of which have a V-shaped notch 30 in the upper end thereof, said members 28 and 29 being adjustably secured on said rod 25 by means of bolts 31, said members 28 and 29 having suitable bearings 33 therein, and the V-shaped notches 30 are adapted to support a textile roll 36' for being operated upon.

In the portions 14 and 15 of supports 12 and 1-3 is mounted a square rod 37 which serves as a slide for a cutting toolimechanism. "This slide 37 is held in position by means of stud bolts 39 and 40, and :on this slide, a member 42 slidably mounted by having :a suitable bearing portion 43, said member 42 being asplitm'ember held in position by means of bolts 44, and one portion ofmember 42 projectsdownwardly as at 45 and has secured thereto cutting tool 46, said cutting tool having a plurality of threaded vholes 47 therein which aread-a-pted to be en- ;gaged by stud bolts 48 slidably penetrating holes in the portion 45 of member 42. This member, 46 projects laterally and has an elongated slot 50 therein in which a plurality of rolling and cutting wheels 51 are rotatably mounted on pins 52 which are fixedly secured in the lower portion of member 46 and span the slots-50,. These rolling and cutting disks 51 are similar to pipe cutting disks and are adapted to follow the old flutes in the roll for building the same up to their original condition, The disks 51 may vary in size and if desired, the central ones may be slightly larger than the end ones.

Member 42 has secured therein a stud bolt 55 on which is loosely mounted bearing portion 56 of connecting rod 57 said connecting 110d- 57 being adjustably mounted in a slot 58 by means of bolt 59 to adjust the length of stroke of the cutting tool, said slot 58 being in one of the spokes of wheel 60 which wheel is fixedly secured on a shaft 61 which shaft is mounted in bearings 62 and 63 in supports 64, and on the other end of said shaft a drive pulley 66 is fixedly secured having a belt 67 connected to any suitable source of power for driving the same.

Spanning the distance between the sup ports 10 and 11 is arod 70 on which is pivotally mounted a lever 71 having a plurality of 7 holes 7 2 therein in which the lower end of a ,rod 73 may be adjustably mounted, and the upper end of this rod 7 3 is pivotally secured to rod 22 for lowering one end of members 20 and 21 and pressing the roll 36 in the path of the cutting tool; Secured to table 9 is a member 7.5 in which is secured a. support 76 which projects laterally overrod 22 and has dulled to provide a roll equivalent all rean eye bolt 77 secured therein to which is secured a tension spring 78, the lower end of said tension spring being secured to rod 22, the purpose being to normally hold the roll holding end of members 20 and 21 away from 70 the path of the cutting tool.

Member 71 has a pedal portion 79-on which the foot of the operator is adapted to be placed for controlling the position of roll 36.

In operation, a roll 36 is placed in the mechanism and the member 71 is depressed which throws the roll in the path of the cutting wheels 51, and the cutting tool slides back and forth on slide 37 and follows the old grooves 80 in the roll.

In Figure 6 it is seenthat the grooves 80 are shallow, as the tips of the flutes have been worn down and an elevation of this is shown in the lefthand end of Figure 5. The passtionin Figure 7.. This does not remove any of the metal from the roll but re-allocates the? metal and builds up the flutesby'pressing the molecules outwardly and upwardly and builds the roll to its original condition rand making the cross-section of the roll slightly larger if desired, than its original condition; and then a suitable dressing operation such as emery cloth and the like is performed on the roll, leaving the tips of the flutes slightly .spects to a new roll. 3-1

It isd-esire-d to be pointed out that this operation is quite unlike the method of filing or cutting new grooves, but on the contrary, this method and means retains all of the metalof the roll and re-allocates' the mole- T cules and builds up the rolls by providing flutes on-the same of the same cross-sectional area as a new roll. I
