WINDINe imaxes'.

Application led August 18, 1925, Serial, No. 49,949.` Renewed June 4, 1926.

This invention relates generally to winding machines;'and has more particularly reference to a reeling means `associated with a paper-makin or other machine from which a web of flexible material flows uninterrupttake up any accumulation of the slack resulting from the break of the web and the necessity of threading it on a new winding shaft.

The main object and feature of this invention is to so arrange the elements that-the accumulation of material on the Winding shaft automatically decreases lthe speed of the driving means so that eventually the shaft will be driven at substantially the same surface speed a.. the drum with which it is subsequently to engage.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which-- -V Fig. 1 is a side elevation of a winding machine, somewhat diagrammatically shown, embodying the invention; and

Fig. 2 is a view looking in the direction of v arrow 2 of Fig. 1.

The winding means consist here of a drum i with which is preferably associated an abutment member that may take the form of a second drum 11, thetwo drums being spaced apart and rotatable in the same di-y rection. Only drum 10 may be `driven ositively as by means of belt 12 but, if desired, both drums may be driven by a silent chain 13 or otherwise. The auxiliary Winding means may takethe form disclosed in the application referred to in which a pulley enga es with a complementary pulley on the winding shaft but, in the present instance, it is preferred to have a surface winding roll 14 extending the full length of the winding shaft; and this roll 14 may be `driven in any suitable way as by means of belt 15 and suitable pulleys from shaft 16. A suitable support, here consisting oftwo arms-17 on shaft 18, is j rovided for l,the reception of winding sha 19. Arms 17 yhave inclined open bearing sockets 20 for the reception of" 1 taken up.

blocks 21 carrying the winding shaft. The

shown as being associated. with a suitable speed-change device and this may conven-4 iently take the form of cone pulleys 100 and 101 together with a belt shifting member 102 'of conventional construction. At the beginning of the winding operation, the surplus winding roll is driven at an overspeed; that is to say, faster' than the web is supplied and faster than the surface speed of drum 10. In this way, any slack that may have accumulated during the change from one wnding shaft to another will be t wi l winding Shaft 19, it will eventually come into engagement with surface drum 10 and means are therefor provided for controlling the speed-change means by the accumulation of material on the winding shaft or by the movement of arm 17 or of some other member bearing a relation to the movement of said arm 17. In the present instance movement of belt-shifting member 102 is accomplished by means of a bell-crank 103, one arm of Which engages belt-shifting member 102 and the other arm of which is engaged bya member 104 conveniently'carried by one of thearms 17. It will be seen therefore that as the material accumulates on the winding shaft, arm 17 will swing around the pivot 18 and will thereby move member 104 in an upward direction; and member 104, being beneath the upper arm of be1lcrank 103, will cause a `tilting movement thereof and then effect a sdewise movement of beltshifting member 102 to move belt 15 on the cone pulleys and therebyl gradually reduce the s eed of surface-winding roll 14. Dur ing tffe subsequent operation ofthe machine,

be understood, however,` kthat as the material accumulates on the` arms 17 are swung so asl to bring winding material on the shaft, means for initially supporting said winding shaft out of contact with the drum, driving means, to rotate said shaft at an overspeed while out of contact with the drum to initiate the winding operation for engagement with the drum, including s eed-c ange means actuated by the accumu ation of material on the shaft to decrease the speed thereof.

2. A Winding machine including: a winding shaft, a surface winding drum to wind material on the shaft, a. surface winding roll spaced from said drum to initiate the winding operation of the shaft, means for initially supporting said winding shaft between the drum and roll but out of contact with the drum and in contact with the roll, driving means, to initially rotate said roll at an overspeed, including a speed-change means actuated by the accumulation of material on the shaft to decrease the speed of said roll so that when the accumulated material rests on both the drum and the roll` said drinn and roll will rotate at substantially the same surface speed.

3. A winding machine including: a surface winding drum, a winding shaft, means for supporting said winding shaft out of contact with the drum, driving means to rotate said shaft While out of contact with the drum at an overspeed to initiate the Winding operation before engagement with the drum, means for moving tliewinding shaft to bring the accumulated material thereon into engagement with the drum to thereby continue the winding operation, and a member following the movement of the shaft-supporting means t0 effect a decrease in the speed of the driving means as the winding shaft approaches the drum.

A winding machine including: a winding shaft, a surface winding drum to wind the material on the shaft, a surface winding roll in spaced relation to the drum t0 initiate thewinding operation of the shaft, means for initially supporting said winding shaft between the drum and roll but out of contact with the drum and in Contact with the roll, driving means to initially rotate said surface winding roll at an overspeed, means for moving the ywinding shaft to bring the accumulated material thereon into engagement with the drum to thereby continue the winding operation, and a member following the movement of the shaft-supporting means to eti'ect a decrease in the speed ofthe driving means as the Winding shaft approaches the drum.
