The calender-roll ":1 is mounted at the upper end of slides, 35. movable diagonally up and down in tubular guides 96. on the main frameovork. and each slide has on one side of it a rack. 97. for engagement with a pinion. by means oi which it is moved back and forth in said guide for a purpose to be hereinafter referred to. The rear roll 94 around which the endless heit passes is supported in any suitable manner. it being shown mounted in the upper end of a rock-frame, 9S. aljustable as by means of rods. 99. pivou l eminecied thereto and adjustable to "liliiiti horizon tal positions. aiming device is also pretei in tion will: the es i in this as a rolli... lii '12 i under side of the in r run m" it it and carried by rock-armsforming: part of a rockframe, 101, pivoted on a rock s iaft. 102. and adjustable in pos iou r the, purpose of varying the tei u eserter in the be t. The ai'ljustnient device sh wn similar to that at 99 in that it en bodi i connected to it. but in addition it has: coiled spr -i-, working between suitaltile stop; and adjustable for the purpose of applying; regulable pressure to the roll 109 and at the same time permitting yielding of the parts.

The main roll 9 around which the end less belt '2 travels is normally tree, to turn on its shaft 105%. and normally the belt. which is in contact with a considerable portion of the circumference of the mandrel. and the calenderroll 21. by which the belt is held against said mandrel. are free to turn in unison with the paper and the mandrel. These parts. however. are intended at the proper time. as before stated. to be driven positively in the reverse direction to that in which the mandrel travels and for the purpose of obtaining such a movement suitable connections are made. preferably LO the main driver. ll e the shaft 6 which carries the pinion 9 ior im 'iarting move. mt to the spur-gear 10 that drives the mandrel also carries at its inner end a spur-gear, 106. which meshes with a spur-pinion. 107. near the left-hand end of the shaft 105 carrying the roll 93. This pinion 107 is intended to impart movement to the shaft 105 when a suitable clutch. such as 108. is thrown into action. This clutch is intended to be thrown in on the seventh or last revolution of the 1 mandrel. and the coupling operation is controlled by a cam. 109, on the cam-shaft. 73, which at the proper point in its rotation strikes an anti-friction roll carried at the upper end of. a shifting lever. 110. pivoted at 111 on the bed-plate or main frame of the machine, which shifting how has a second upwardly-extending arm, 112, engaging in the usual manner a collar, 113, shiftable on the left-hand end of the shaft 105 into engagement with the clutch 108, for the purpose of starting into rotation the shaft 105 in the same direction as the mandrel, to cause the belt 92 to travel in a direction opposite that of the surface of said mandrel, and thus produce a wiping-0n action or pressure on the paper of the last layer, and especially at the end of the sheet.

In the machine shown it is intended that the mandrel shall be stopped at the end of the seventh revolution. Suitable automatic stopping means will be employed for this purpose, that shown in the present machine embodying a cam-wheel. 114, on the camshaft 73 near the left-hand end thereof, which eanrwheel cooperates with the starting lever or releasing lever 13 before described. and to restore it to lilSdlOl" mal position. In the construction shown said lever 13 has a second upwardly-extending arm, which is indicated at 13', terminatin in an antifriction-roll which drops into a cam-groove of the cam-wheel 114 when the machine is in readiness to be stopped. This results in the latching of the lever 13 to the spring-pressed detent 17 again, as shown in Fig. 9, and the consequent stopping of the shaft 11. The stopping of, the mandrel. however, does not result in the stopping of the travel of the belt and calenderroll in the reverse direction to that in which the mandrel was traveling, and this movement of the endless belt to Wipe on and smooth out the last layer of the tube may continue as long as the operator deems necessary.

For the purpose of completing the tube by cutting and trimming the same, the usual cutter mechanism may be employed, which comprises a cutter-bar, adjustably mounted in the standards 5 and 5, and carrying inthis instance a plurality 115, adapted to be thrown into and out of action by a suitable hand-lever, 116, in a well-known manner. a

()n the completion of the winding and cutting of the tube, various parts of the 11' mechanism require to be thrown out of action or operated. One element of the mechanism that will be thrown out of action at this time is the calender-roll and other elements of'the wiping-on device. The 1 throwing of this part of the machine out of action is accomplished in the present caseby the operator raising a handle and crank, shown at 117 and 118, which crank is secured to a shaft, 119, carried by the 1 brackets, 120, and having spur-teeth in mesh with the teeth of the racks 97. When the crank 118 is thrown up by the operator these spur-pinions will be turned and thn'mcks. l with the calender-r011 and the upper of rotary cutters, 1i
