Patented Jan. 6, 1931 UNITED STATES PATENT OFFICE PAUL W. LEHMAN, OF MILWAUKEE, WISCONSIN, ASSIGNOB TO THE FISH RUBBER COMPANY, OF CHICOPEE FALLS, MASSACHUSETTS, A CORPORATION OF MASSA- OHUSETTS' WIND-UP APPARATUS Application filed June so, 192s. Serial no. asatsa.

My invention relates to machines for cutting and winding web materials and more particularly to machines for cutting and winding tacky rubber materials used in the manufacture of rubber articles such as pneuual labor usually involved to a minimum.

In the accompanying specification and drawings I have shown one embodiment of my invention in which, v

Fig. 1 is a plan view of a cutting and windin machine;

ig. 2 is a side elevation of the machine shown in Fig. 1; I

Fig. 3 is a detail erspective view of certain worklng arts. of t e machine;

Fig. 4 1s a partial side elevation but taken on the opposite side from that shown in Fi 2- Fig35 is a view taken on line ,5--5 of Fig 4; Fig. 6 is a sectional view taken on me of Fig. 5; and

Figs. 7, 8 and 9 are diagrammatlc views showing the operation of Winding mechanisms.

In the drawings 10 represents a general supportin frame on which is mounted a motor 11 riving, thru reduction unit 12 and chain drive 13, a shaft 14 to which is attached a standard two-way clutch 15. One end of clutch 15 is connected by chain drive 16 to a shaft 17 on which is mounted a conveyor driving roll'18 driving a conveyor belt 19. The other end ofclutch 15 is connected by chain drive 20 to a shaft 21 which is in turn connected by chain drive 22 to a shaft 23 bearin an indexing cam 24 which engages a clutc shifting member 25. A tension spring 26 is pinned to the clutch shiftin member 25 and tends to hold the latter in t e postion shown in Fig. 1 and an operating lever 27 permits a manual operation of the clutch 15. Also connected to shaft 21 by chain drive 28 (see Fig. 4) is a cam driving shaft 29 .which is in turn connected by chain drive 30 to another cam driving shaft 31.

Pivoted and supported on the shaft 17 (see the cutting and Figs. 2, 3 and 4) is a swing frame 32 which supports guiding rolls 33 driven by a belt drive 34 and complementary gears 35. Cam rollers 36 attached to the swing frame 32 engage with cams 37 on cam shaft 29 to determine the movements of the uiding rolls 33. Also pivoted and supporter? on shaft 17 is another swing frame38 carrying a heated knife 39 which, as shown in Fig. 6, may be insulated as at 40 and heated by an electric unit 41. Indirectly connected to the swing frame 38 by spring arrangements 42 (Fig. 5) are cam rollers 43 engagin cams 44 on cam drive shaft 31 to determine t e movements of knife 39 and thru spring arrangements 42 to pro.- duce a yieldable pressure on the knife 39 as it c0mes against the cuttin supports 45.

Attached toshaft 17 see Figs. 1 and 3) is another two-way clutch 46 adapted by clutch shifting member 47 on shaft 48, linkage 49, shaft 50, and linkage 51, to be shifted first one way and then the other by the movements of swing frame 32. One end of the clutch 46 drives thru chain drive 52, shaft 53, bevel gears 54, vertical shaft and bevel gears 56, a winder driving roll 57 and the other end of said clutch drives thru gearing 58, shaft 59, bevel gears 60, vertical shaft 61 and bevel gears 62, another winder. driving roll 63.

Positioned, as best shown in Fig. 3, be-

neath the, winder driving rolls 57 and 63 are rolls of liner material 64 supported on trucks 65. The liners are passed over positioning bars 66 and then to windup bobbins67 which are positioned by guideways 68 to rest on driving rolls 57 and 63 with enou h pressure so that as the latter are-rotate they will wind the bobbins. 7/

The conveyor belt 19 is driven by roll 18 (see Fi 2) while guide rolls 70, weight rolls 71 and 2 moving 111 guideways .73 in frame 10 and another drivin roll 74 form the belt into a storage loop. The driving roll 74 is connected by chain drive 75 to a shaft 76 which is in turn driven by chain drive 77 connected to anassociated manufacturing machine. not shown. The shaft 76 drives a cooland a ide roll 81. The chain drive 77 rotates t e cooling roll 78 at a constant speed and the chain drive 75 is of such ratio that it rotates the driving roll 74 at the same surface speed as cooling roll 78.

The operation is as follows: a web of rubber or rubberized material is fed over the cooling rolls 80 and 78 under guide roll 81 and onto the conve or belt 19 at driving roll 74. It is then carried by the conveyor belt to drivin roll 18 and then down thru the guiding ro s 33 onto the liner 64 and is wound on the bobbin 67 as shown by the arrows in Figs. 1, 2, 3 and 7. As soon as the bobbin has the desired amount of material the operator shifts lever 27 to reverse the clutch 15 and to simultaneously disengage the indexing cam 24. The chain drive 16, shaft 17, conveyor driving roll 18 and the windup driving roll 57 then become stationary and the power acting thru chain drive 20 and shaft 21 drives thru chain drive 22 and shaft 23, the indexing cam 24 and thru chain drives 28 and 30, cam driving shafts 29 and 31. Thru the action of tension spring 26 the clutch shifting member 25, after one revolution of indexing cam 24, will return to the position shown in Fig. 1 to restart the conveyor driving roll 18. The ratios of the chain drives involved are such that as the indexing cam 24 makes one rvolution the cam shafts 29 and 31 will make onehalf a revolution and the cams 37 and 44 will move the guiding rolls 33 and the cutting knife 39, respectively, as shown in Figs. 7, 8 and 9, to cut the material and position it to be wound on the opposite bobbin. As the guid ing rolls 33, due to the action of cams 37, are moved from the position shown in Fig. 7 to that shown in Fi 9, the linkage 51 which is pivoted to the gulde roll support 32, will act thru shaft 50 and linka e 49 to shift the clutch 46 and as the sh 17 is restarted it will deliver the power to the gearing 58 and thru its associated gearing to its windup driving roll 63 while the windup driving roll 57 powered by the chain drive 52 will now remain stationary. At the next cutting and shifting period of operation the movements of the guide rolls 33 and knife 39 will be the same but in a reversed direction, i. e., from the position shown in Fig. 9 to that shown in Fig. 7, and the power-will be reshifted to winder driving roll 57 leaving winder driving roll 63 stationary.

As the conveyor driving roll 74 is constantly rotated it necessarily follows that when the driving roll 18 stops, the weight roll 71 will travel down and weight poll 72 will travel up in the guideway 73 thus storing the material during the cuttlng and shifting periods. The speed of the motor 11 may be varied by any of the several known methods, not necessary to show on the drawings, to maintain the weigiit rolls 72 73 at the proper working leve 64 and overhead tracks 82 for hoists to handle the full bobbins, it is possible for one operator to run the machine.
