Operation A web roll Winder made according to this invention will generally be used in a train with a number of cars adapted to carry a plurality of rolls. In the application of the invention envisaged by the applicant, the web rolls handled by the invention are belt rolls, for example the belting that is used in belt conveyors.

A train goes to a belt conveyor location including in its train a belt winder made according to this invention and one or more belt carrier cars. When the location for a conveyor is reached, a roll of belting is removed from the carrier car to the belt Winder. This is done by turning the base on its vertical axis until it is oriented in such a manner that a roll of belting may be easily rolled onto the transport |26. The roll of belting is of course rolled into place with the core |06 `and spindle |04 removed from the bearings 86 and 88.

The transport is then raised in order to bring the belt center above the bearings 86 and 88. Raising ofthe belt is accomplished by admitting duid under pressure to the left end o1' hydraulic jack |12 as seen in moved to the right, the pulley |66, thus rotating n vertically by v1rtue of the guides |38 and guide blocks |40. When the belt roll has been raised as high as necessary,

conveyor. The belt is then ready to be unbanded and to be unrolled onto the conveyor as will be well understood by those skilled in the art.

Let it now be assumed that a section of belting is to be remo-ved from a belt conveyor. A belt Winder according to this invention is pulled to a stop as close to the conveyor as is possible and the base is swivelled on its vertical axis until it is alined with the belt line of the conveyor. The belt on the conveyor is unhooked by breaking the belt at a lacing, and the upper run end of the belt is connected to the core |06. The connection is'made by passing one or the other of the pins or rods |08, ||0 through the depending on the size of the belt lacing. The be wound onto the core |06.

connected as aforesaid, power is applied to the hydraulic motor |20. It will be understood by those skilled `in the art that, at the outset, the radius about which the belt winds is relatively small, and a relatively high torque is available with only one of the

pump sections

200, 202. Accordingly, the pump section which is not to be used will merely by-pass oil through its control valve.

Let it be assumed that pump section 202 suilices at thestart to wind up the belt and drag the tail piece. In that case, pump section 200 will simply by-pass oil through its control valve 204, `and pump section 202 will pump oil under pressure to theV hydraulic motor by way of conduit 2|0, through control valve 206,

conduits

224 and 222, control valve 220, and conduit 234. Fluid returns from the hydraulic motor by way of

conduits

236, 228, and 2|2, reservoir 2| 4, and conduit 2|8 back to the pump intake. As the belt piles up on the core, the radius of the belt roll increases to the point Where the pump 202 cannot supply the necessary torque. If then pump 200 Vupon both pump sections 200 and to drive the hydraulic motor.

It will be obvious to 'those skilled in the art `that flexible tension members |48 and |66 can- `not transmit compressive forces. In other words, the transport |26 will have to move downward by the influence of gravity." Nevertheless, the

hydraulic jack I12-is preferablymade a doubleacting jack in order that the piston vrod 114 may be powered leftward as `seen in Fig. 8. This makes it possible to eliminate sticking of the jack and does not limit the operator to the force of gravity in moving the jackv parts to effect lowering of the transport |26.

A web roll winder made `according to this `invention provides means for handling heavy belt rolls completely by power, .thusobviatingthe tedious, awkward, and often dangerous handling .of heavy rolls of belting underground where` maneuvering space is often very limited. A belt Winder made according to this inventionoperates with very low head room and is exceedingly flexible in its application. Other advantages will be apparent to those skilled in the art.

While there is in this application specifically describedone form which nthe .invention may assumeY in practice, it will -be understood that this `form of the same is shown for purposes of illustration, and that the invention may be modilied and embodied in various other forms without departing from its spirit or the scope of the appended claims.
