To all whom it may concern:

Be it known that l, Evans Hansen, a citizen ot' the United States, and a resident ot'the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Slitting and liewinding Machines, of which the following is a specification.

The present invention relates generally, though not exclusively, to slitting and rewinding machines, and has more particularly reference to means for eflectivcly separating side by side sections of flexible sheet material.

Certain materials, such as tinfoil, adhesive tape and other materials of a tacky or sticky nature when slitted into sections have a tendency to reunite at the adjacent edges of the slit-ted sections during reminding on the same shaft or side by side. It has been attempted to overcome this defect by revvinding the sections on separate shafts, but this is disadvantageous because in that Way the sections will be rewound into coils of varyingr diameters which consequently exert dif ferent pulls on different sections at the plane of severance with the result that the slitting is distorted and is not edected. evenly. It is therefore preferable that the slitted sections be rewound on the same shaft or side byhide in order not to sheet adversely the, slitting-operation. 'With this side by side rewinding construction attempts have been made to edect a physical separation of the slitted sections by passing or guiding them through combs or a plurality of series of pins, transversely arranged in each series, and each series having the pins or combs spaced farther apart than the preceding comb or series ofpins. While this cdectually spreads the sections and physically separates them, it has a decided disadvantage in that the side edges of the sections are apt to be turned and folded back on themselves so that when rewound under pressure the turned-back edge becomes embedded in the coil. lln slitting and revvinding tinfoihtor instance, the coil, owing to the heavy pressure exerted in rewinding', becomes practi' cally a solid piece of metal in which the turned-back edge becomes embedded and trend which it cannot be separated,

The main object of this invention is to spread slitted sections of material Without turning back the edges.

Other objects Will appear as the specification proceeds.

(line feature; of the invention consists in bodily deflecting the slitted sections into laterally spaced relation, as distinguished from deflecting the side edges of the material. lhis bodily deflection of: the section is out of the plane of the web or out or the plane of severance and is effected with a progressively increasing pitch so as to let erally separate the sections. The slitted sections which are thus bodily deflected are then brought back into one plane and re-- ivgund in lateral spaced relation side by s1 e. 7

Another feature out the invention con." sists in a spacing or spreading device con sisting of two straight rollers, and a member, composed of one or more parts, located intermediate the two straight rollers and having; inclined surfaces of progressively increasing pitch laterally, together With. means forguiding the sections over said rolleggs and member. Suitable means are also provided for holding the sections under tension. In-the preferred form herein disclosed, this is ellected by mounting the first straight roller rotatably and in providing means for retarding the rotation of the said roller, together with means for exciting a pull on the sections.

' Preferably also the inclined surfaces are arranged in two series extending in opposite directions, each series having a progressively increasing pitch. i

A still further feature of the invention resides in adapting this spreading or spat ing device to a typeot slitting machine embodying the scorecut method in which the cutting roller against which the cutters act also does duty as the second straight roller, the member with the inclined surfaces being located intermediate it and the first roller, and the Web sections being led from the cutting roller to the first roller, then under the member with the inclined surfaces and then back: to the upper part of the cutter roll. This cutter roll may. if desired, also form a part of the rewinding mechanism,

Other features of constr lClJlOH, combina: tion of parts and arrangement of elements will appear as the specification proceeds.

In the accompanying dra rings the invention is disclosed in several concrete and preferred forms, from which, however, changes may be made without departing from the legitimate and intended scope of the invention as expressed. in the appended claims.

In the said drawings:

Similar characters of reference indicate corresponding parts in the several views.

1 indicates the cutter roll of a slitting and rewinding machine with which cooperates s plurality of cutting members, one of which is shown at is straight roller located in front of th cutter roll and rotatably mounted in the bracket 4.. is the spacing or spreading member located intermediate the cutter roll 1 and the roller 3. In the embodiment of the invention shown in Figs. 1, 2, 3 and l, the member Sconsists of s shaft ii provided with a plurality of cone shaped members 7 arranged in two series ext-ending laterally in, opposite directions from the central member 7 which is straight. The cone-shaped mei'nhers a ororrressively increasing pitch its best seen in Fig. 4, so that '5 has a, greater inclination than 7*, and l has 'ier inclina tion than 7 and so on, In present instance, the members i ere secured to the sbar't s by means screws 9 or otherwise' ll. brake band 9 secured to the pin 10 on the brecltet e and passes over the roller 3 and thenceover the pin 11. The lower end of the brake bend is weighted as at 12 The cutter roll 1 forms a part of the rewinding mechanism and together with the roller 13 and pressure roller 14 acts on the coils 15 on the rewinding shaft 16 to rewind the slitted memos sections, the members enumerated exerting a pull on said sections.

The web 17 is passed up between the roll 1 and cutters 2 where it is slitted into sections. These sections then pass to the roller 3 at the underside. thereof, up around the same, thence to the underside of the member 5 and up over the cutter roll 1 to the rewinding shaft 16.

The sections in passing from roller 3 to the cutter roll 1, under the member 5, are deflected bodily out of the plane of the web, without the necessity of engaging the side edges of the sections. Owing to the constant increase in pitcl: of the cones, the first section, next to the middle section is deflected, say 1/64 inch, while the second section isdetieeted Q/G-elinch and so on; each section being separated from its next preceding section. The sections in passing to the cutter roll 1 are l hen all brought back into one plane, but remain laterally separated and are then rewound side by side in laterally spaced relation. The brake band 9 serves to retard the rotation. of the roller 3 and prevents a saelt from, accumulating between the rollers 3 and l and the member 5, which slack would interfere with the control of the sections. It will be seen that the deflection of the sections out of the plane of the web by the action ot the member 5, amounts to a tilting, or rotating, of the sections about their longitudinal whereby the lateral edges of the sections are laterally deflected. The engagement of the tilted sections at a later stage in their movement with the roller 1, produces :3- tilting of the sectionsin the reverse direction about one of the laterally deflected erilges, with the consequent, bodily lateral displacement of the sections as a whole,

The bracket is adjustably mounted. on thers'tuds 1'2", which latter are seated in the open hearings 18. adjusting the studs 17 in said bearings 18, the member 5 may be moved to the position found most advantageous in a given set of circumstances.

The coneshaped members 7 may be provided with segments 19 constituting abutments to prevent undue slippage of the sections. The shaft 6 of the member 5 is adjustably mounted in the bracket a but is normally held in one position by 11 cans of the pull sprin 20 secured to one end of the belt 21 passing; over the puller 22 on the end of shaft 6 The other end of the belt 21 passes to the foot lever 23, the upward movement of which; under the influence of the spring 20, is limited by the stop 24:. When threading the sections through the machine the foot lever 23 may be depressed thereby imparting half a turn to the shaft 6 and bringins, the segments 19 uppermost, thereby iacilitating the threading operation. After the sections are threaded the lever 23 is rethey fur varying-g" the ififieciimi betwaen SQCiLiUHEi ziu 5L pi'ngiessi'veiy changiiig and. subs'tmb m liI- ig s. 5, (i iia'ily mristani; wire, and means for def :ct illfllnb k. 05E iiig; the sestinma aboiii the nthei." edge a :icijmmbiy pix i; 31 1163 in the commit-y dii'ectimn "whereby 7?
