' IMRROVEMENI IN'MACHINES FOR CUTTING AND ROLLING PAPER.

Specification forming part of Letters Patent No. 209,868, dated November 12, 1878; application led August 10, 1878.

To all whom it may concern:

Be it known that I, ERNEST DANeoIsE, of Brussels, in the Kingdom of Belgium,lr have invented certain Improvements in Machines for Winding Paper into Rolls, of which the following is a specication:

The object of my invention is to construct a machine for cutting and trimming paper, fabrics, and similar material, and winding :it up into rolls; and this object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is a side elevation of the machine, and Fig. 2 a front view.

To bearings on the opposite side frames of the machine are adapted the journals of a drum, H, which is driven, through the medium of suitable gear-Wheels, from the driving-shaft, carrying the smoothing-roller C. O11 the drum H rests the roller E, onto which the continuous sheets of paper, after they are cut, are wound, the journals of this roller being adapted to bearings arranged in gui-des lJ in the opposite side frames of the machine. To these guides are also adapted plates, which form bearings for three rollers, D, G, and F, the two former being arranged to rest on the rolls of paper, which are wound ou the roller E, while the roller F carries a series of circular cutting-knives, Fig. 2, arranged at points corresponding with the widths of pa-V per desired to be cut.l Theedges ofv these knives are adapted to corresponding ,grooves in the roller D, and onthe roller'G are arranged a series of blades, corresponding in position to the knives on the roller F, for a purpose explained hereinafter.

The cutter-roll F is driven from a vertical shaft, M, through bevel-wheels c o, receiving motion from the driving-shaft through suitable gearing.

The front plates N of the guides P are removable, so that the roll E may be withdrawn when it is desired to remove the rolls of paper from the roller E.

The plates which form the bearings forthe rollers F DG have secured to them vertical racks K L, controlled by pinions on a horizontal shaft, .I, furnished with retainingpawls and ratchets, so that the said rollers may be raised to any desired height after the required amount of paper has been wound on the roller E.

The rollA of' paperto be cut is arranged on the lower part ot' the frame, as shown in Fig. 1, and immediately above this roll vis the stretcher or tension device X, s0 secured to the opposite side frames that it can be adjusted to different angles to vary the tension. This stretcher carries two bars, B and B', the paper from the roll A first passingv over the bar B and under the bar B', and ythence over.

the roll C, which, being caused to rotate in a direction opposite to that pursued by the paper, smooths the paper and removes all creases therefrom. The paper then passes over the roller D and between the latter and the cutter-roll F, by which the said paper is cut into a number of strips of the required width, these strips being wound by means of the drum H onto metal or Wooden bobbins arranged on the roller E. The rollers D G, resting on the rolls of paper as they are wound onto the said bobbins, give the required tension and-pressure to the paper, While the rings orfblades Q on the roller G, enteringy between the strips of paperfasY they are Wound into rolls, guide the said' strips and insure the formation of even and compact rolls.

If desired, the cutting-knives on the roll F, except those at the ends for trimming the edges of the paper, may be dispensed with, in which case the blades Q on the roller G are so constructed aspto cut the paper to the proper widths as it is wound onto the roller E, these blades thus servin g the purpose of both cutting and guiding the paper. i

I claim as my inventionl. The combination of the winding drum and roller of a paperwinding machine with a pressure-roll, D, and a roll, G, provided with rings or blades, the said pressure-roll and roll G having bearings in the same adjustable plates or frame, substantially as set forth. i

The combination of it winding-roller, E, vided with removable plates N, its and for the cutter-roll F1 and roll Gr, provided with rings purpose set forth. ,or blades for guiding' the rolls of paper, subu testimony whereof I have signed my sta-ntially as specified. i name to this specification in the presence of' 3.
