This invention pertains to a rug rolling and wrapping machine, and has primarily for its object to provide a machine which rapidly and efficiently rolls and wrapsa rug, without the use of a winding bar orcore, thus materially facilitating theoperation, with minimum labor and effort on the part of the operator.

Incidental to the foregoing, a more specific object of the invention resides in the provision of a power-driven machine into which one edge of a rug is fed and directed into a spiral wind, which, when completed and wrapped, is ejected from the machine by a manually actuated mechanism.

Another object of the invention resides in the provision of a driven floating roller cooperating with a pair of fixed driven rolls, to effect both rolling and wrapping oi! the rug without the aid of a central core or pole, such as now employed.

A still further object is the provision of a pressure roll cooperating with one of the fixed driven rolls to hold the rug upon the same, together with fingers cooperating with the fixed driven rolls for guiding the leading edge of the rug into a spiral wind, and subsequently ejecting the rolled a and wrapped rug from the machine.

Lastly, it is an object to provide wipers operatively connected to the floating roller for automatically tucking the ends of the wrapper.

With the above and other objects in view,which will appear as the description'proceeds, the invention resides in the novel construction, combination, and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such' changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings are illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Referring now more particularly to the accompanying drawings, the numeral I indicates generally a fabricated frame consisting of end members 2 connected by longitudinal struts 3, which are supported at spaced intervals by suitable legs 4. Spaced intermediate the end members 2, and connected to the longitudinal struts 3 are transverse beams 5, which carry fixed driven rolls 6 and 1, respectively, the shaft 8 of the roll I being journaled in bearings 9 mounted on the'crossm Journaled in brackets 16, carried by a suitable m framework I! connected to a pair of intermediate legs 4, is a driven shaft l8, provided at one end with a drive pulley l9, which may be driven by a belt from a motor, or other source of power,

not shown. Mounted on the shaft I8 is a sprock- 25 et 20, alined with sprockets 2| secured to the shafts 8, l0, and I4, all of which are operatively connected by a link-belt or chain 22, one stretch of. which. receives a floating sprocket or pulley 23,- carried by a shaft 24, the ends of which re- 9 ceive weights 25 vertically guided between spaced uprights 26 carried by the frame l'l. Obviously, the floating weighted sprocket 23 serves to retain tension upon the link-belt 22, and also compensates for transverse adjustment of the roller h.

Slidably mounted on the end members 2 are brackets 21 for reception of vertical rack bars 28, provided at their upper ends with bearings 29 in which a longitudinal shaft 30, that carries a flanged roller 3| is journaled. Transverse ad- 4 justment of the brackets 2'! on the end members 2 is obtained by jackscrews 44. Inasmuch as it is desirable to drive the floating roller 31, a compensating drive 32 is provided at one end of the machine, and comprises a pair of pivotally con- 45 and meshing withthe rack bars 28 to impart vertical movement-to the bars and roller 8|, for the purpose hereinafter explained. For rotating the shaft 38 and pinions 39, a lever 40 is loosely Journaled on the shaft 38 and provided with a manually actuated detent 4| for selective engagement with the teeth of one of the pinions 39. Obviously, when the detentengages the pinion 39,and the lever d is rotated downwardly, vertical movement will be imparted to the rack bars 28, which causes the floating rollertl to be raised. At the same time, when the lever 40 is in its normal raised position, and the detent t! is disengaged from the pinion 39, the rack bars are free to move upwardly as the diameter of the rolled rug increases during the rolling operation to be later described.

As best shown in Figure 1, downward movement of the rack bars 28 is limited by fixed collars 42 carried by the rack bars and engaging bosses on the brackets 21. After a rug has been rolled and wrapped as hereinafter explained, and it is desired to remove the rug from the machine, it is necessary to raise the floating roller 3'! sufficiently to allow the rug to clear the roll, and this is accomplished by actuation of the lever, 40,

' which rotates the pinions 39 in the manner described. In the raised position of the roller 3!, the lever til is releasably latched in its lower position indicated in. dotted lines, by a pivotal dog it carried by the adjacent end member 2.

To hold the rug against the roller 6, particu- I larly during the initial winding operation, a

longitudinal floating roll t? is mounted above I the roller t, by means of spaced arms 48 secured upon a shaft ll pivotally connected to the frame 3, as best shown in Figures 2 and 4. To facilitate insertion of the leading edge of a rug into the winding rolls, it is desirable to provide for raising the roller d5 upon completion of each rolling operation. Therefore, an arm dB is secured to the pivotal shaft lll, and extends into the path of travel of the shaft 30, which carries the floating roller iii, When the roller Si is raised subsequent to completion of the winding operation, the arm 65 is engaged by the shaft 3@, which in turn rotates the shaft l? to raise the roller d5.

To assist in initial guiding of the leading edge of a rug into a spiral wind, as shown in Figure 5, a plurality of arcuate fingers d9 are mounted upon 3 a longitudinal shaft 58, pivotally carried by the frame i and projected between the flanges of the rolls 6 and i. In addition to serving as guides for the rug, the fingers 69 are also utilized to eject the rug upon completion of the winding and wrapping operations. This is accomplished by means of a foot pedal 5! pivotally carried by the frame l and connected with an arm 52 secured upon the shaft 5%, by a link 53. Obviously, depression of the pedal 58 will rotate the forward ends of the fingers d9 upwardly, causing the rolled rug to be forced over the rear driven roll l for removal from the machine. If desired, tracks or any other receiver may be provided for the ejected rug.

Immediately prior to completion of the winding operation, wrapping of the rug is provided for by inserting the wrapping material, preferably consisting of a sheet ofstifi cardboard (a) and an outer covering sheet of paper (72), between the turns of the rug in the manner shown in Figure 5, after which the driven rolls are again put into operation to wind the wrapper over the rug. As best indicated in Figures 3 and 4, theends of the wrapper W extend beyond the 'rollsand the,ends of the rug R, and therefore. to complete the wrapping operation, rotary tuckers '1 are-sethe rug, and which upon rotation engage the pro-' jected ends of the wrapper in a wiping action 7 to tuck the same inwardly against the ends of the rug, where they are glued, taped, or otherwise fastened.

From. the foregoing explanation considered in connection with the accompanying drawings, it will be seen that a. machine has been provided for both winding and wrapping rugs or strips of pliable material, such'as floor padding, carpets, linoleum, and the like; and due to the fact that the entire operation, including starting, winding, wrapping, and ejection, is accomplished through the operation of themachine, labor and time required. are reduced to a minimum.

In operation, it is merely necessary for the operator to place the leading edge of the rug over the forward roller 6, after which the racks 28 are lowered to allow the roller it to engage the driven roll 5, and the floating roll 3! to mesh with the fixed driven roll l. The machine is then put into operation, and, as best shown in Figure 5, the leading edge of the rug will be guided from the roller 5 to the roller l by the fingers t9, and thence into contact with the periphery of the floating roller 35. Due to the fact that the periphery of the rollers l and at are travelling in opposite directions at their meshing point, the

leading edge of the rug is prevented from continuing over the driven roller 6, the roller 3i serving to deflect the same and force'the edge into contact with the rug, resulting in a subsequent spiral wind, as shown in Figure 6.

Upon completion of the winding operationand.

insertion of the wrapper as heretofore explained,

- the further rotation of the rug serves to wind the wrapper over the s after which the following edge of the wrapper is glued to the previous turn to seal and completely house the rug, the ends oi the wrapper being tucked and secured as heretofore explained. The roller at is then lifted upon actuation of the lever ti, and the wrapper roll is easily ejected by manipulation of the foot pedal El.

The advantages of the foregoing will be obvious when considered in connection with conventional methods now in use, in which two operators' are required to place the leading edge of the rug into a slot of a winding core or bar, which must then be inserted into the machine after several turns are made to securely attach the rug to the core. Then, upon completion of the wind, the core must be pulled from the machine, and two operators are required to wrap and tape the ends after the rug is removed from the machine.
