UNITED STATES PAPER-ROLL STAND.
Application filed. December 21, 1922. Serial No. 608,218.
This invention relates to a stand for holding rolls of paper in position to be delivered to a printing machine or other machine through which a continuous strip of paper is to be fed.
It will be understood by those skilled in the art that in the manufacture of manifolding books and other paper products of that character, that the paper is delivered to the machine, either a printing machine, folding machine or die-cutting machine in long strips or webs. In order to supply the ma chine with paper fast enough, it must be delivered to them from a roll, at the same time means must be provided to prevent the roll from unwinding, as well as to hold back the strip of paper to cause it to be delivered to the machine under a substantially uniform draft.
Other objects of the invention will appear as the description proceeds.
An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but we are aware that there may be modifications thereof.
Fig. 1 is a side elevation of the complete machine, Fig. 2 is a view of the machine in elevation looking from the right, Fig. 1,
Fig. 3 is a plan view of the complete ma chine, I
Fig. 4 is a detail view of one of the roll brakes, and
Fig. 5 is a side elevation of a portion .of one of the paper strips and its supports, showing the means for regulating the move ment thereof through the machine, and
Fig. 6 is a plan view on a larger scale than the other figures of a portion of one of the paper strip carrying rolls, and the means for tightening it against its supporting bearing. The machine is tended to handle diiferent widths of paper, and to attain this object is provided with a base 1 having a plurality of inverted T-slots 2 to? inclusive extending transversely thereof.
Extending upwardly from the front end of the baseare two frames 8 and 9 which 60 are suitably secured to the base and which form the support for the rollers, over which the paper strip passes. 7
The groove 2 carries a step-bearing 8 for the post 9', while the groove 3 car- .is a spiral spring 26 The roll supports consist of a shaft 14 carried by a block 15 slidable on one of the posts 9, 12 and 13, there being one of said roll supports for each of said posts.
The block 15 is secured in any given p0 sition by means of a set-screw 16 and the rod 14 is secured in place in the block 15 by means of a nut 17.
The rod 14 carries a sleeve 18 slidable on said rod and it also has two frustoconical members 19 and 20 thereon on which the roll of paper is placed to be passed through the paper stand preparatory to feeding it to the other apparatus. Q
The member 19 is slidable on the tube 18, but the member 20 is secured thereto and it has a drum 21 which is surrounded by two half- circular brake members 22, 23. These two members are joined in a lug 24:, and at their other ends there is ascrew 25 having a nut 26 thereon and under which nut there for tightening them or loosening them on-the tension of the paper roll.
The lateral as it is pulled'olf the position of the paper roll and thereby the position of the paper strip is ad, justed by means ofthe screw 27 which has a hand-Wheel 28. This screw passes through the block 15 and passes through the lug 24 in which it freely rotates.
This particular machine is intended to handle three rolls of paper at one time and to make it possible to re lenish either one of said rolls without interfiiring with either of the others. 7
The upright frames of the machine consist of flat plates each of which is bored to receive 4 flanged bearings 30, to 33 inclusive and four other openings are provided through which shafts 34 to 37 inclusive are assed. P The bearings 30 to 33 carry four shafts 38 to 41 inclusive. The shafts 38 to 41 each carry rollers 42 somewhat larger than said shafts and over which the paper strips pass.
Shaft 34 carries two bell cranks 43, 44 and boss 21 to regulate the the bell crank 43 has a longer arm 45 connected therewith extending to the lower part of the frame 8 where it is connected with a lever 46. This lever is carried by a shaft 47 which shaft has two arms 48, 49 rigidly connected therewith and which arms in turn have links 50, 51 connected therewith, and connected to a small roller 52.
The shaft 47 is supported by two adjustable standards 53, 54. There are eight of these standards each of which has a depending foot member which fits into the slots 4 to 7 inclusive in pairs.
The rollers 42 are driven by a series of gears 55 to 62 inclusive at such a rate that the peripheral velocity of the rollers 42 will be slightly greater than the requisite feed velocity of the paper strip, the object of which is to be presently explained.
Each pair of arms 43, 44, of which there are four pairs, is provided with a roller 43, and the normal position of said rollers 43 of which there are four is immediately over the rollers 42.
The shafts 35 and 37 carry slides 63 and 64 over which the paper strips A, B and C pass to the printing apparatus. The shafts 35 and 37 also carry arms 65, 66, 67 and 68, which armsin pairs, support the two small rollers 69 and 70.
The position of the rollers 69 and 70, with respect to the paper strip may be varied by means of the two hand wheels 71 and 72 on the shafts 35 and 37, and when moved to a desired position, the said shafts are locked in a given position by means of the nuts 73 and 74, which are rotated by means of the handles 75 and 76.
As shown in Fig. 1, the two rollers 69 and 70 are out of contact with the paper strip. The opration of the apparatus is as follows:
Assuming a roll of paper to be placed on each of the stands, as indicated in Figures 1 and 3, the paper strips A and C are passed over the upper roller 42 and under the upper roller 43, then under one of the small rollers 52, then up over the next roller 42,
' under the next roller 52 and then over the upper slide 64 and under the small upper roller 69.
The paper strip B is passedover the third roller 42, under the third roller 52, over the fourth roller 42, under the fourth roller 52 and then over the slide 63 and under the last small roller 70.
The pressure on the s ring 26 is arranged to hold the roll 0 paper from unwinding any more rapidly than is required, however, should the speed at which one of the strips of paper moves over one of the rolls 42 become greater than it should be, the tendency will be to lift up the corresponding one of the small rollers 52 thereby causing one of the rollers 43 to bear down on the paper strip as it passes over the roller 42 immediately under it. This will cause the roller 42 to pull the paper 0d the roll a little more rapidly than the printing press requires it thereby slackening the tension on the paper strip and roll 52.
From the foregoing structure it will be seen that the slack of the web is used to control the speed of the feed, and that the tension is regulated by the tension screws 25, and tension levers 75, 76, and that as soon as one of the rollers 42, increases the speed of the web thereover, the corresponding small roller 52 descends, causing a reduction of pressure on the roll 43, and on the roll 42, with a corresponding decreasing of speed of the web feed over the roll 42.
VVhatwe claim is as follows, but various modifications may be made in the' construction shown in the drawings and above particularly described form, within the purview of my invention.
1'. A paper roll stand, comprising supports tor a plurality of rolls of paper, means to adjust the position of each roll longitudinally of its axis, means to regulate the tension required to pull the paper strip 0d the roll, a plurality of other rollers over which the paper passes in a series of loops, 2. plurality of longitudinally adjustable rollers under which the loops of paper pass in succession, and means whereby the excess pressure on the latter rollers will cause an acceleratiolf of the paper movement to reduce the pull on said paper strip.
2. A roll paper stand, comprising an adjustable support for a roll of pa er, adjustable resilient means to retard t e rotation of said roll of paper, rotatable rolls over which the paper strip passes, said rolls havinga peripheral velocity greater than the feed velocity of the paper strip, idler rolls under which said strip passes in succession, a shaft mounted in a bracket, two arms fixed to said shaft, one of said arms being connected to one of said idler pulleys, the other acting on a long arm of a bell crank lever pivoted adjacent one of said rotatable rolls, the short arm having a roller bearing on said rotatable roll.
In testimony whereof we have hereunto set our hands this 9 day of December A. D. 1922.
