CORPORATION 'OF-NEW YORK rarna WINDING MECHANISM 1 Application filed September 12, was. i Serial No. 892,001.

ihis invention relates to paper winding mechanisms. I i

In most paper mills, the paper comes in a continuous sheet from the machine andis wound on a roll or reel. Consequently, a winding mechanism is desired which will receive the paper continuously and permit rapid change of winding from a full roll to an empty or fresh roll so that there is little or no loss of paper in Changing from one roll to the next.

One form of winding mechanism embodies a rotating drum driven at a uniform speed the same as, or slightly faster than, that of the oncoming'sheet which contacts with the drum periphery and is driven thereby. in the usual form of this mechanism, a plurality of rolls are removably mounted adjacent the drum with one roll in a winding position and another out of winding position, but adapted to be brought into such position when the first roll is iilled and ready to be'removed.

It is the object of this invention to improve such mechanisms, to make the construction more simple and practical, and render the operation more reliable and dependable. The

invention embraces improved means for supporting and moving the winding rolls out of and into winding position, and includes mechanism for adjusting the positions of the rolls and aligning them.

The invention further consists in certain features, combinations, arrangements and details of construction which will first be described in connection with the accompanying drawings and then more particularlypointed out in the claims.

. in the drawings,-

Figure 2 is a plan view of this mechanism;

Figure 3 is a front elevation of the mechanism.

The embodiment chosen to illustrate the invention comprises a rotatable drum 10 other horizontal surface. The drumv is intended to be rotated at a uniform speed the same as, or slightly faster than, that of the oncoming sheet The rotating means illustrated as an example involve a belt-driven.

cone pulley let having a shaft 15 aligned with shaft 11 and connected thereto at one end by a suitable coupling 16 and journaled at the other end in a bearing 17 carried by a floor standard 18. The embodiment further includes a plurality of rolls, in this case, two rolls 19, having shafts 20 projecting from each side of each roll and positioned horizontally in parallelism with shaft 11 of the drum. The paper is wound on one of these rolls, that shown to the right in Figure l, which is in contact with the drum, while the other roll is out of winding position at the left andout of contact with the rotatable drum.

Means are provided for removably journaling the rolls. As here shown, the rolls are movably journaled in bearings 21 open at the top to permit entrance or removal of the projecting shaft ends of the rolls. The shafts are equipped with collars 22 which abut against the sides of the bearings, when the shafts are placed therein, to insure proper axial disposition of the rolls.

The invention in its entirety involves means for movably supporting the roll bearings whereby a roll may be moved out of winding position and another roll moved into winding position. Although capable of various constructions, in that here shown as an ex ample, the roll bearings are removably positioned on parallel supporting members the form of beams and may be moved on said members and adjusted. As here shown, the members are carried and pivoted on the free ends of links or levers 24, as by pins 25. The left hand links (Figure l) are pivoted at their lower ends 26 to standards 13, the right hand links fixed on an auxiliary shaft 27 which is arranged parallel the axes of the drum and rolls and journaled in standards 13. The links are advantageously of equal length so that'the supporting members keep their same inclinations.

Meansare present for rotating the links on tit - ment is ac larger ameter, the

Means are provided for shifting the positions of the roll bearings on the supporting members. In the construction shown, the supporting members house elongated screws 37 extending throughout their lengths and meshing with half-nuts 38 on the undersides of the roll bearings (Figure 3). One of said screws has a hand wheel 39 for rotatin it. The screws may be connected by a cross s aft 40 through bevel gears ,41. The cross is advantageously housed in a casing 42. Provision is made for moving the cross shaft into and out of connecting position and, to this end, a shifting cam 43 or similar mechanism for moving the shaft may be provided. Usually, the cam is thrown to connect the screws and to cause simultaneous movement of'all the bearings. If, however, the windin roll is out of ali nment or parallelism with the rotatable drum, this can be remedied by throwing the cam to disconnect the screws and by running the hearings on one supporting member only until align- 'eved.

In operation, the paper'coming from the paper machine on the leftfFigure 1) goes under a spreader 44, which is advantageously adjustable, over the rotatable drum and is wound on the right hand roll into a paper roll of the desired size. In this winding action, the supporting members are free to rise as the. aper rqll builds up to larger and weight of the paper roll holding it in contact with the rotating drum.

- When the roll is of. the desired size, it is swung away from the rotatmg drum by action of the hand wheels, while the empty roll is brought into contact with the drum and winding now continues on this-roll. The completed roll is then removed from the machine, and by manipulation of the hand wheels the newroll is brought into the position formerly occupied by the full roll, the empty bearings of the removed roll being first removed and later put in the former position of the new roll so as to receive another empty roll. The insertion of a new empty roll does not, therefore,

"The roll being wound may be easily placed in contact with the rotating drum at different points and at any desired point by the manip -ulations of the hand wheels. As the roll builds up and its weight increases, the links shaft interfere with the winding operation.

move into a more nearly vertical position and take up more and more ofthe weight, thus relieving the drum of the additional weight due to increase in the roll. The pressure of the paper roll on the drum is thus practically constant, in spite of the increased size and weight of the roll.
