MACHINE FOR CUTTING AND WINDING RIBBON TAPE Filed June 9, 1935 g FNVENTOR, QEEM$ 1M ATTORNEY Patented Mar. 3, 1936 UNITED STATES PATENT OFFICE MACHINE FOR CUTTING AND WINDING RIBBON TAPE Application June 9, 1933, Serial No. 675,008

3 Claims.

This invention relates to machines for cuttin and winding ticker tape or ribbon tape and more especially to tape supporting cores and adapters associated with such cores.

Ticker tape as it is extensively used today by stock quotation tickers, news tickers and the like is composed of various grades and kinds of material, which is some times practically opaque and at other times practically transparent or translucent of varying degrees according to the use to be made of the tape. Cellophane, glassine paper and specially treated translucent or transparent paper of many different varieties have recently been extensively used in order to facilitate using these tickers in association with projectors. The tape here under consideration is the ribbon type, the standard width of which is about three-quarters of an inch. This ribbon tape especially when composed of glassine paper and translucently converted paper is generally cut from rolls of paper of about twenty-four inches in width.

In practice, rolls of this width, that is about twenty-four'inches in width, are generally out by a standard cutting machine having a plurality of circular knives while the paper is being transferred from a single supply roll to a plurality of individual ribbon tape rolls. These standard cutting machines generally are provided with a shaft having mounted thereon a plurality of tape cores composed either of wood or fiber having a width approximating the width of the tape to be out. In these machines, these cores are mounted side by side on a shaft and there ;clamped into position. The rotatable cutting knives are spaced apart the width of the tape to be'cut. 'With these machines, the knives were of course accurately spaced by metallic spacers. The cores, however, whether composed of wood or fiber would vary from day to day depending upon the humidity in the air as an instance. Furthermore, since the grain of the wooden cores and the composition of the fibrous cores would vary, the moisture absorbing qualities would vary, making it practically impossible to select a series of thirty-one cores of either of these materials which would be equal to one another in size and dimension for any considerable length of time. In view of the foregoing, when a series of ribbon tape rolls were cut and simultaneously Wound on either wooden or fibrous cores, the rolls would overlap adjacent cores making it necessary for the attendant to use a sharp wedge shaped instrument or the like to pry the adja- ;cent rolls from one another, resulting not only in injury to the edges of the tape but frequently in distorting the rolls.

Still furthermore; due to the variations in the cores themselves, when the tape rolls were si-' multaneously wound by the rotation of a comeven feed of the tape would be impossible resulting not only in objectionable magnified vibrations but in a magnified image of the incongruous result produced when an impression coincided with a crease or fold as aforesaid.

In view of the foregoing, the present invention aims to provide a core that can with facility be accurately predetermined both as to size and dimension and which will also be immune to variations in humidity.

More specifically, the present invention aims to provide a core composed of a metal such for instance as steel'which can be accurately cut and dimensioned and be free from variations due to humidity and the like.

A particular feature and advantage of the present improved core resides in the fact that the pressure exercised in winding can be materially increased resulting in a core of maximum compactness.

In practice heretofore, it appears that the diameters of the shafts for receiving the tape vary. As an instance, the tape receiving shaft of the Western Union ticker is approximately .375 of an inch in diameter, whereas the tape receiving shaft of the New York Stock Exchange tickers is approximately 1.085 of an inch in diameter. In view of the foregoing, a supply house would either have to have tape rolls with different cores, one for each type of ticker or else have to supply adapters for the cores having the larger inner diameters when tapes on such larger cores were required to be used with the tickers having the smaller shafts. These adapters similarly have heretofore been made of wood and the like. In view of the variations pointed out above, difficulty was encountered in properly alining tape rolls with such adapters and securing the same against wobbling. To this end, the present invention also aims to provide improved adapters which can with facility be accurately sized and dimensioned to ac- 5 commodate one standard large core and which adapters can with facility be positively secured in alinement and against wobbling.

More specifically, the present invention aims to provide an improved adapter composed of steel or the like material which can be accurately cut and dimensioned and provided with securing means for positively securing the same to the core and to the tape roll receiving shaft in proper alinement and against wobbling or chattering.

It is still another object of the present inven tion to provide an improvedmachine for cutting and winding ticker tape characterized by winding the ticker tape as it is out onto corescomposed of steel or the like, which cores form an intimate part of the cutting and winding machine when cutting and winding the tape, and subsequently form an intimate part of the ticker tape supply roll.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specific embodiments thereof illustrated in the accompanying drawingin which Figure 1 is a transverse section of a paper cut-- ting machine adapted for use with the present invention;

Fig. 2 is an enlarged longitudinal section of a core made according to the present invention;

' Fig. 7 is a transverse enlarged section of the adapter shown in Figs. 5 and 6.

The present invention consists essentially in providing a core I' preferably composed of steel or the like'material which is accurately sized and" dimensioned both as to thickness of wall and also as to diameters and curvatures of the outside and inside peripheries.

These cores I in the present instance for supporting a roll 2 of ribbon tape, such as glassine paper or the like of about .75 of an inch in width are preferably formed with a wall thickness of about .0985 to .1025 of an inch, a width of about .750 to .751 of 'an inch with an inside diameter of 1.085 to 1.089'inches and an outside diameter of about 1.1875 inches with the corners broken off and all burrs removed to form the beveled'edges 3! and 3 8, with the corners of the core I so re- -moved that adjacent cores I although in engagement with oneanother will present a clear di-', vision at their adjacent edges to afford'clearance for the cutting knives I5 hereinafter to be described.

In the process of cutting the tape, these coresare mounted on a shaft 3 with itsdiminished ends 3 and 3 journaled in the enlargements 4 and 5 extending from the side plates 6 of a standard cutting machine.

on the shaft 3, thirty-one cores I aggregating a.

total width of 23.25 inches.

The enlargements 4 and. 5 of the cutting ma chine itself, see Fig. 1, are each provided with a guide slot 9' in which the diminished ends it and 3 of the shaft 3 are slidably mounted. The

paper P is initially mounted in. a roll, to wit the roll I0 on the shaft II journaled in the frame sides 8. From the roll III, the paper is guided by the guide rods I2, I3 and I4 to the cutting knives I 5 and I6. The cutting knives I 5 are preferably circular cutting blades mounted on the driven shaft IIand the knives I6 are similar circular cutting blades mounted on the driven shaft I8.

The blades I5 and I6 complement one another preferably'being arranged, one blade I5 between each of two successive blades I6;so as to formthirty-two paper engaging cutting points to form" thirty-two incisions on the paper, to remove the waste end portions and form thirty-one accurately sized paper ribbons or tapes.

From the blades I5, the paper tapes initially pass to the cores I on the shaft 3 and subsequently to build up the rolls 2.

Asa further guide for the paper tapes. there is provided the driven roller 20 mounted on. the shaft 2I- journaled in the sideframes 6. For maintaining the tapes being wound in proper engagement with the winding roller 20 and the cutting blades I5, the pressure roller 22 is provided. This pressure roller 22 is provided with diminished ends slidably mounted in the slots 9' formed in the side frames Sand is connected to the loweren'd'of the link 23 pivotally connected at its upper end to the arm 24 which in turn is pivotally mounted on the bar 25 extending from one to the other.

side frame '6 The arm 24 has preferably mounted thereon a tween successive cutting blades and also provide a reliable mounting to accurately aline the cores I on the shaft 3 when the divisions between successive cores I may be alined accurately with the cutting blades I5 and afford suflicient clearance for the cutting edges of the blades I5 especially since the winding roller 20 will determine the initial position of the cores I,see Fig. 1, relative to the cutting edges of the blades I5.

The paper P as shown in Fig. 3 is secured to the cores I by a suitable adhesive 29 positively to anchor the advance free edges of the paper I" on the cores I.

When the ticker, such as the ticker 30 is provided with one of the narrow tape receiving shafts 3|, there is provided in the present instance an adapter such as the bushing 32 preferably composed of steel or the like material. The adapter is preferably provided with a screw receiving recess for the screw 34 having an enlarged countersunk recess to receive the head of the screw 34. Preferably diametrically opposed to the screw opening for the screw 34, there is provided a recess for the spring pressed ball and its spring 36 with the edge of the recess spun over to retain the ball 35, see Fig. 7.

The adapter 32 for a core I such as heretofore described is preferably .6875 of an inch in width with the shoulder 33 about .0312 of an inch in width. The diameter of the shaft receiving opening of the adapter 32 is preferably .3755 to .377 of an inch. The diameter of the outer periphery of the shoulder 33 is preferably 1.25 inches and the diameter of the outer periphery of the core receiving face of the adapter 32 is preferably about 1.081 to 1.083 inches.

It is obvious that various changes and. modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I claim:
