JAMES A. CAMERON, 0F BROOKLYN, AND JOHN A. HAWKES. OF NEW YORK, N. Y.,

ASSIGNOBS TO CAMERON MACHINE COMPANY, OF BROOKLYN, NEW YORK, A COR- POBATIOH OF NEW YORK.

BLITTING AND RE'WINDING MACHINE.

To all whom it may concern:

Be it known that we, James A. CAMERON and Joan A. Hawxrs, citizens of the United States, and residents, respectively, of the borough of Brookl n, county of and State of New ork, and of the borough of Bronx, county of Bronx, city and State of New York, have invented certain new and useful Improvements in Slitting and Rewinding Machines, of whichthe following is a specification.

The present invention relates to slitting and rewinding machines, and more articularlyto machines espmially adapte to the slitting and rewindm of paper of tough fiber or of-tacky or a esive material, or of tin foil.

Whencutting tacky or adhesive material or the like it sometimes happens that the edges of the slitted sections will re-adhere after being separated, thereby rendering it difficult to separate the rewound coils. ifficulty is also experienced in separating coils of rewound material when the diameter of the coils is exceedingly large and the width of the slitted sections is exceedingly narrow.

. The main object of this invention is to insure the permanent separation of materials of this character after slitting and during the rewinding.

In carrying out this and other objects, the invention consists of the hereinafter claimed features of construction,. combination of arts and arrangement of elements, a preerred form of which is disclosed in the ac-' companying spechication and drawings.

In the said drawings: Fi re 1 is a longitudinal vertical sec tiona view tbrou h a machine embodying a.

preferred form 0 the invention.

Fig. 1 is a detail view of one of the slip drive connections interposed in the line of gearing.

Fig. 2 is a fragmentary plan view of the spreading means located a jacent to the rewindin device.

Fig. is a sectional view showing one of the tension and separating rollers projecting between the coils of the rewound material.

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 2.

5 constitute the slitting means and, as shown, 0

are preferably of the score cut type, the backing roller being glass hardened and harder than the cutter 5.

The slitted sections of the web 2 may now pass directly over the backing roller 4 to 66 the hi roller 6, or thei may pass around the guide roller 7 and t ence back between the backing roller 4 and nip roller 6. If the material takes the latter course separating blades 8 may be employed which project in between the slitted sections of the material and sever any unsevercd threads or fibers.

The nip ro]ler 6 en ages with the upper side of the backin ro ler 4 and is mounted in the arms 9 (on y one of which is seen),

said arms being pivoted on the shaft 10. The latter, in this instance is provided with a gear 11 which convenient] receives its motion from the gear 12-on the shaft 13 of the backing roller-.4. Mounted loose from the shaft 10 is another gear 14 between which and the car 11 there is a slip friction drive 15, the s ippnge of which is adjusted by means of the spring 16 and nut 17. The

gear 14 meshes with an intermediate gear 18 B5 .on one ofl the arms 9 which in turn is in mesh with the pinion 19on the nip roller 6. By adjusting the tension of the spring 16 the amount of slippage can be ad 'usted and consequently. the tension of the n1 roller 6 on the slitted sections can be vari The slitted sections of the web 2 now pass over the table 20 and in between the pins21 which constitute a comb extending transverscly of the table for separating the slitted sections.

22 is a tension roller extendin transverselyof the machine and provi ed with separating blades 23 between which the web sections pass, after which they are led underneath the bat-kin roller 24 of the rewinding device, an thence over tension roller 25 also provided with separating blades, and thence to the reivinding shaft 26. The rewinding shaft 26 is mounted in the arms 27 (only one of which is seen), which arms are pivoted on the shaft 28. lly reason of this construction the rewinding shaft 26 will become displaced with respect to the backing roller M as the diameter of the reu'ound coils increase. Motion is im parted to the rewinding shaft by means similar to those which transmit motion to the nip roller 6. That is to say: there is a gear 29 on-the shaft 30 of the backing roller 24 which meshes with a gear ill on the shaft 28. Loosely mounted on this shaft 8 is another gear 32 between which and t e gear 31 there is a slip friction device similar to 15. The gear 32 meshes with the intermediate gear 35 on one of the arms 27, which .in turn drives the pinion 36 on the rewinding shaft 26. A counterweight 37 is adjustably mounted on the extension 38 of the arm 27 and may be used to counterbalance the weight of the rewound material.

From the foregoing construction it follows that; by adjusting the tension of the slip friction devices the material may he ledunder considerable tension over the hacking roller 4: to prevent wrinkling and may be loosely rewound if. desired, or vice vcrsa,

, or the web sections may be fed from the nip roller 6 to the separating and rewinding devices without ovcrpulling by the latter. The provision of a slip friction drive for the nipping roll 6 is chiefl important in that the nipping roller may e driven at a differ- .ent peripheral speed than that of the backwill be obvious.

ing roller 4 to thereby produce relative motion between the two rollers. This results in causing 'the nipping roller to exert a rubbing or smoothing action on the web, as

In fact by the various independent adjustments descrihed the machine may be suited to work on different materials.

Motion may be imparted to the two ends of the machine by means of the shaft 38 provided with bevel gears 39 which mesh wi h corresponding bevel gears on. the shafts 30 and 1 3.

In Fig; 1 the tension roller 25 is shown as projecting into the coils of rewonnd material, thus keeping the web sections Separated when rewinding. This tension roller 25 is here shown as being pro idedaiiit h a counterweight-4O which servcs tokcep it, in engagement; with the ren'ound coils.

Fig. 5 the construction is substantially the same except that a chain 41 is utilized to connect the shafts 30 and 13. Also in this

instance rollers

42 and 45 are arranged at either end of the table 20. the roller 15 having separating blades 46. and a tension roller 1-; counterweight d at It and prnvidml with separating blades 18 extends n between the coils of rewound material. The web sections here pass directly from the table 20 over the roller 45 and thence over the tension roller 43 to the rewinding shaft .26 lalwvmt the latter and the hacking member 24.
