-7 Claims. '(cl. 242-55 My invention relates to sheeting machines, its

primary object being the provision of a'device' which reels sheet material from the roll and into a convenient form for cutting'the materialinto sheets of the desired length.

Another object of the invention is the provi-' sion of a simplified structure for adjusting the reel in order to obtain sheets of the, desired lengths.

Another object of the invention is the provision of connections between the bars and the armsof V the reel for preventing binding action when the material is being wound on the, reel.

Another and a very important object of the invention is the provision of a knife guide on the reel so that the material may be most effectivel out into sheets of the desired length. 7

I also have in 'view the provisionof "a clamp" for securing the material at its end edge to the reel, the clamp being operative inla manner so 'that the reel may beturned in either direction to unroll the material from any one of a plurality of rolls which are supported on the frame of the'machine.

. Having in view these objects and others which will be pointed out in the following description, I v

will now refer to the drawing, in which Figure 1 is a view reel.

The frame ID of the machine is shown in very conventional form in Figure 5. This frame may be varied in numerous ways, its function being.

primarily to support the reel at a convenient height and to support one or more rolls of the in perspective of the entire bars and the clamps which secure the bars tothe,

rotation. The arms ll pass through and extend to both'sides of the cylindrical members I2 to which they are secured by means of set screws [4. The bars l5span the distance between the end portions of the arms ll, these being the bars on which the sheet material is reeled. Clamps I6 are employedto connect the arms I I and the bars 7 l5. These clamps aresplit .as shown in Figure v 3 so that a very firm clamping action may be obtained by tightening the screws l1. The ends of the bars l5 are reduced to fit loosely into sockets I6 in the clamps IS in the manner shown in Figure 3. This loose connection is for the purpose of preventing binding action especially after a number of layers of the sheet material has been reeled. At the beginning of the reeling operation there is very little difficulty from binding but the tension increases rapidly with the number of layers on the reel and it is when the tension increases that the loose connection of the bars I5 with the clamp l6 compensates to a very large extent for the binding action.

The spacer or spreader I8 is firmly secured at its'opposite. extremities to the two cylindrical members. I2. This spreader functions not only to spread the two layers of sheets on the reel but it serves also as a knife guide and as a support for the paper clamp. It consists of two plates I9 and 20 of uniform width and an inter mediate plate 2| having a width less than that of the plates l9 and 20. The spreader may be either laminated as shown in Figures 1, 2, and 4 or of integral construction as shown at l8"in Figure 5. A clamp 22 is hingedly secured to one of the plates I9 or 20 by means of hinges .23. The clamp furtherincludes a screw 24 passing through a suitable aperture in the clamping member 22 and into either of the plates l9 or 20.

In use the material is unrolled from a roll 25 and its free' edge is secured by means of the clamp 22. The reel is then turned by hand by means of the crank 26 so that the material is wound on the reel. Where only one rolb is employed, one clamp 22 will serve the purpose as the rotationof the reel will always be in the same direction. When a number of rolls are supported on the frame H], a secondroll 2? may be in position such that it will not readily reel but this difficulty may be overcome ,by the use of clamps 22 on both sides of a spacer. The spacer may be the spacer I8 comprising the several parts as shown in Figures 1, 2 and 4, or it may be integral as indicated at l8 in Figure 5.

countered in cutting this material because of its relative; hardness and because of its peculiar A shear action is wholly unsatisfactory anji the number of layers which can be thus cut is very limited. For this reason I provide a novel form of cutting guidewhich will function with the blade ofi an ordinary jack knife or any other suitable cutting blade. The plate 2| is narrower than the plates is and 20, thus affording: a channel between the plates. l9 and as for the passage of a cutting blade, this channel being underneath the layers of Cell-ophane or other sheet material. is thus provided so that the knife cannot slip. to cut the material with irregular edges. While Cellophane is very hard and thus resists shear action, it is sufficiently brittle especially when under tension to respond readily to the sliding knife action of a cutting blade sliding in the groove between the plates l9 and 20 of the spacer I8.

The reeling of the material is accomplished in a manner indicated in Figure 5. The operator merely turns the crank handle 26 until the desired number of layers of the material have been reeled. This operation is stopped with the handle 26 directed downwardly and with the channel between the plates l 9 and 2!] directed upwardly. A cutting blade is then inserted in the channel at its end and is then drawn through thechannel from end to end of the web spacer i8, thus slitting all of the layers of the material on a straight line. The material will then be in the form of sheets of substantially uniform dimensions. The width is of course governed by the width of the material in the roll. Any width not exceeding the length of the web spacer l8 may be reeled. The length of the sheets may be varied by adjustment of the clamps IE on the arms H; For this purpose the arms II are graduated in distances from the axis of rotation. By thus adjusting the reeling bars l5 toward or away from the axis of rotation, the sheets may be cut in any desired lengths.

Having thus described my invention in such full, clear, and exact terms that its construction and operation will be readily understood by others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patentof the United States'is:

. 6. A reel winding device'comprising av rotary reel element having spaced bars about which webs of material are wound during rotation of the reel, there being a transverse bar intermediate said spaced bars, said transverse bar having a portion adapted to project into the path of'the webbing as it is wound about the reel whereby it be tightly engaged thereby, said portion being provided with a longitudinal notch forming a guideway into which a cutting tool may be inserted to cut the layers of webbing material while the webbing remains in tight engagement with said portion.

7. A winding reel comprising a spindle, arms projecting radially from the spindle, bars secured attheir ends to said arms about which webbing may be wound, and a spacer element secured to the spindle, said spacer element having a portion adapted to project into the path of the webbing as it is wound on the reel to be tightly engaged thereby, and said portion being provided with a longitudinal groove forming a guide for a cutting tool to cut the webbing wound on the reel while the webbing, remains in" tight engagement with said portion.
