2 Claims. (CI. 92-71) The present invention relates to machines in l which a web of paper or other flexible material is traveling from one mechanism to another.
A web of paper seldom, if ever, possesses uniform characteristicsthroughout, but it usually has a variation in thickness in a given zone that persists lengthwise for a long distance and which,
when the web is wound into aroll, tends to produce circumferential welts. cessive, must be removed, a process that requires rewindingof the paper. The main. though not exclusive, object-and feature of this invention' is to prevent the formation of these welts during initial winding of the web, i. e. as the web comes from the paper-making machine and as it passes to the winder or reel.
In the accompanying drawings the invention is disclosed in a concrete and preferred form, in which:
Fig. 1 is a somewhat diagrammatic side elevation of a structure embodying the invention; 2 is aftop plan view of the parts shown in Fig.- 3 is a detail view looking in the direction of arrow -3 of Fig. 1; and
Fig. 4 is a sectional view substantially on the planeof1inellofFig.3.
The paper-making machine is here indicated by a stack of calenderlng rolls A, and B is the winder, here of the surface-winder type employing two winding drums l and 2 that rotate in the same ditatably mounted in a slide l2 secured to the shank of roller 5 and slidably carried by stud l3 of bearing 6. Mounted on bearing 6 are two bearing brackets I4 that support a pivot [5. I5 are links that connect said pivot with'cranks I1 that rotate with worm wheel ll. It will now be understood that rotation of roller 5 causes rotation of worm wheel II and therefore of cranks These welts, if exl1, and that rotation of the latter, by reason oi links l6, anchored on pivot 15 of stationary bearing brackets It, causes periodic bodi reciprocation of slide l2, wormwheel ll wonn l0 and rol1er5.
It will thus be seen that, the periodic bodily reciprocation of roller 5 is due to its own rotation, and that the speed of said bodily reciprocation depends upon the speed of the web and is not dependent upon outside factors and, furthermore, by subjecting the web to the reciprocating bodily movement before it is wound, the tendency to form circumferential welts, that might later re- 1.

The web of paper or other flexible material is indicated at W. C indicates a' guiding device that is interposed in the path of the traveling web as.

machine to the cate lengthwise of its axis in bearings 6 and 1. Roller '5 is driven by web W, the latter being trained around said roller by means of two rollers l and 9. Suitable means are provided to convert the rotating movement of roller 5 into a bodily movement of reciprocation of said roller. 7 in-the present instance, roller 5 is provided with a worm II at one end that engages a worm wheel ll roincluding: ,a freely rotatable roller mounted to bodily reciprocate lengthwise of its axis, around which roller the web is trained and by which it is-rotated, means to train said web around said roller to thereby rotate the latter by frictional engagement and to cause said web to follow endwise reciprocation of the roller, and means, actuated' by said .roller upon rotation thereof, to effect lengthwise bodily reciprocation of said roller.
