In a reel frame having a single tier of reels Any reel, except the end reels, when exhausted the replacement of an intermediate reel presents is readily replaced by lifting out its spindle and no special difficulty so far as guiding the leading lowering a full reel in lieu of it. To'enableend 85 end of its web is concerned, as the end will be reels to be replaced as readilyiprovision is made guided into its running path by the webs on each for shifting the reel next to the end reel into side of it. To permit of the replacement of an the end position and placing the bearings of the exhausted end reel the invention provides for end reel in the position thus vacated. For this an intermediate reel being brought to the end purpose the two sets of bearings are arranged 90 position while its Web is still unwinding, and upon a slanting part of theframe 1 so that the for a new reel to be placed in the position thus unexhausted reel next the end reel may be readvacated. ily'lowered into the end reel position.

The saddle is also capable of 105 The invention is illustrated in the accompanysliding at right angles upon a similar guideway ing drawings in which- 8,both guideways being sufficiently interrupted Figure 1 illustrates diagrammatically a single where they meet to allow of the passage of a tier reeling machine; saddle along the guideway 7 past the guideway 8,

1 Figure 2 is a fragmentary side view} or from the guideway'? on to the guideway 8. 0

Beneath the guideway '7 is secured a lead screw 9 rotatable through bevel gears 10 from a suitable handle. Each bearing carries a half nut 11 which can be engaged with or disengaged from the lead screw by rocking the handle 12.

The procedure upon the end reel becoming exhausted is as follows: Its empty spindle is lifted out. Its bearings are slid up to and along the side track 8. The bearings of the adjacent reel are in engagement with their lead screwsS and these are then turned to lower the reel from which the web is still unwinding into the end position. There the half nuts 11 may be lifted from the lead screws. What were previously the end bearings are then slid back on to the tracks '7 and along them to the intermediate position where their half nuts 11 are engaged with the lead screws 9. A full reel is then lowered into the bearings.

Alternatively swinging arms may be employed for lifting over the reel next the end reel from its intermediate position to the end position. In Figure 5 such swinging arms are constituted by a three-armed spider 13 each arm carrying a hearing. The two spiders are separately pivoted to permit the passage of the paper web when a reel is carried from the intermediate to the end position. They are rotatable by the hand wheel 14 through a worm 15, a worm wheel, and two sets of chain gearing 16, one for each spider. These spiders are set at such a distance from the spindles of neighbouring intermediate reels that any arm when not carrying. a reel can rotate past the spindle of the adjacent intermediate reel.

In this case when the end reel is exhausted its spindle is removed and the spiders .13 are rotated through 120 whereupon a new reel can be lowered into the previously empty bearings which have thus been brought to the intermediate position. t

Where the number of reels is considerable they may be mounted in two tiers as shown in Figure 6, The reels 23 of the lower tierwhich can neither be lifted vertically as can those of the upper tier nor removed laterally as can the reels 24-may be replaced while the machine is running by making their. bearings movable so that they can be shifted out of the way of a; new reel introduced endwise upon a trolley. A construction for this purpose is illustrated diagrammatically in Figure 7. The bearings 17 fit loosely in brackets 18 which are pivoted at 19 upon frames 1 and which may also have dovetailed projections 20 engaging in are shaped recesses of corresponding section 21 in the frames 1 when the brackets are swung into reel-supporting position. When a reel is exhausted its bearings are withdrawn from the brackets, the brackets are swing out at right angles, 7 as shown for the middle bracket in Figure 7, and a new reel is run into place upon a trolley. Guide rails 31' are provided in order that there may be no danger of a reel so brought in touching its neighbours. When the reel is in position the brackets 18 are turned back into line with the frame 1 and the bearings are. replaced in them upon the ends of the reel spindle. p

The end pair of reels 22 of the top tier are interchangeable in the manner explained with reference to Figures 2, 3 and l, and the end reels .23 of the bottom tier may be similarly interchangeable.

I claim: 1. In a machine for supporting reels of paper the reels be fullor nearly empty.

2. A machine for supporting reels of paper to be unwound and discharged as a multi-layer web comprising a frame, a plurality of pairs of bearings for supporting shafts of reels of paper, means'for guiding the webs of paper unwound from each reel to bring the webs together to form a multi-layerweb, and means for shifting the bearings of the reel supplying the web layer next to the surface layer of the multi-layer web to the position of the reel supplying the surface layer when the supplying of paper from the latter has ceased.
