The inclined track is carried by brackets I5 secured to the frame I6. To guide the roll A in its travel on the inclined track I3, so that the roll is prevented from tilting or from assuming a position- oblique to the posi tion it is to occupy at the receiving station I4, there are disposed at opposite sides of the track I3 pivoted guide members constituted by upstand In one such construction in which the sliver is wound between two end discs each unitary with a half arbor, on completion of the roll, arms car rying the end discs are swung apart, thereby with ing arms, one of which is indicated at I 1, of a drawing the half arbors from the roll, which rolls 10 loaded lever. Said lever is pivotally mounted down an inclined track to a receiving station, at I8 on the brackets I5 supporting the inclined while the discs and half arbors return to starting track I3. Each arm I1 is normally retained in position for the winding of a fresh roll. raised position by a spring I9 connected at one An object of the invention is to guide the roll end to a bracket I5 and at the other end to an in its travel along the inclined track so that the 15 extension I1' of the arm I7. roll is prevented from tilting or assuming a po 'I‘he arms I'I are spaced apart a distance slight sition oblique to the position it is to occupy at the ly exceeding the width of the roll A and are receiving station. bridged by a cross-stay, in the case illustrated With the said object I dispose at-opposite sides in the :form of a plate 2U extending above the of the inclined track guide members spaced apart 20 inclined track I3 in the path of the roll A. a slightly greater distance than the width of the It will be understood that, as the roll A travels roll, said guide members being formed by plates, down the inclined track I 3, it mounts on and bars or the like constituting upstanding arms of depresses the plate 2U, thereby rocking the lever a loaded lever, preferably a spring-loaded lever, in opposition to the springs I9, so that the up said arms being bridged by a cross-stay extend 25 standing arms I'I swing in the direction indi ing above the inclined track in the path of the roll. cated by the arrow B. , The said cross-stay may be in the form of a In order momentarily to retain the arms Il in plate which may or may not be cambered. the lowered position, indicated by dot-and-dash It will be understood that, as the roll travels lines, while the roll A settles in its position on down the inclined track, it mounts and depresses 30 the receiver, there is provided on one bracket the cross-stay, thereby rocking the lever in the I5 a pivoted catch lever ZI, the hooked head cf direction towards the receiver, so that in effect, which is normally in the path of movement of a the lever arms travel parallel with the ends of projection or pin 22 on the adjacent arm I1, the roll on its way to the receiver. whereby, as the arm I1 rocks about the pivot I8, After the sliver roll leaves the cross-stay, the 35 the projection 22 tilts the catch lever 2| about lever returns to its initial position, the sliver end its pivot 23 until in the continued movement of leading back from the finished roll to the fresh the arm I1 the projection 22 becomes engaged stream of sliver bein-g thrown back in the direc in the hooked end of the lever 2 I. tion towards the half arbors which are about to As the roll A passes to its position in the re begin the winding of a iresh roll. , The single ligure of the accompanying draw ing illustrates a sliver roll forming machine, showing in full lines a sliver roll in position im 40 ceiving station I4, itdepresses the tail end 2l’ of the lever ZI to release the catch, whereupon the arms Il under the influence of the spring I9 return to initial position.

In order to impart an impetus to the roll A being unitary with a half arbor, indicated at II, to start it on its travel down the inclined track and carried by a hinged arm I 2, the arrangement 50 I3, there is provided a lever 25, secured on the being such that, on completion of the sliver roll pivot 26 of the arm I2, which lever is bent at the hinged arms I2 are swung apart, thereby its free end 25’ to lie'across the width of the withdrawing the half arbors II from the roll A rollerA., which rolls down an inclined track I 3 to a receiv ing station indicated at I d.

By this move ment of the arms I2 the bent end 25’ of the lever 25 is caused to' press against the periphery of the roll A to start it on its travel down the inclined track. The upstanding arms I1 are guided in raised a distance slightly exceeding the width of said track, said guide members including normally up standing lever arms, and a cross-stay bridging said arms and extending above said track in the path of the roll, so as to move with the roll and thereby rock said arms inthe directiontowards said receiver. > ` ` ' _ l2.
