6 Claims. (Cl. 242-56) My invention relates to apparatus and processes for winding a web and the like.

A purpose of my invention is to simplify and cheapen the construction of web winders, while at the same time making them very reliable and less likely to r'equire maintenance.

A further purpose is to eliminate the unsatisfactory gear drive for the gate previously used in a Simpson type web Winder, and to manipulate the gate by fluid means manually started and automatically reversing.

A further purpose in a web winding machine is to employ a plurality of winding drums, a shell on which web or the like is wound, rotating in contact with one of the drums, a knife having an inactive position below the path of the web being wound, uid mechanism for raising the knife into a cutting position, manually operated means for starting the fluid mechanism and automatic reversing means for the iiuidmechanism for lowering the knife to inactive position when the web has been cut.

A further purpose in a winding machine is to employ a pair of spaced parallel winding drums, a shell on which a web or the like is wound, rotating in contact with one ofthe drums, and adapted to move from one drum to the'other, a shell on which the web or the like is to be wound, rotating in contact with .the other drum, a vertical gate between the drums and beneath the web when it extends across the space between the drums, having a lower inactive and an upper active position, a knife adjacent the top of the gate adapted to cut the web. guide fingers adjacent the top of the gate adapted to guide the cut end of the web, fluid mechanism for raising the gate to carry the knife into cutting position and the fingers into guiding position, manually operating means for starting the fluid operation and automatic reversing means for fluid mechanism for lowering the gate when the web has been cut.

A further purpose is to employ, in a winding machine, a cylinder, a piston in the cylinder, appropriate connection between the piston and the knife above described to raise and lower the knife and desirably also the guiding fingers, preferably by acting on a gate carrying the knife and the fingers, a source of fluid pressure, a uid valve connected to the source of fluid pressure and to both ends of the cylinder, having a closed position, an open position connected to one end of the cylinder and an open position connected to the other end of the cylinder, with an exhaust position for each open position connected to the 2 opposite end of the cylinder from that connected to the source of fluid pressure, manual means for throwing the valve into the position to raise the knife and preferably also the guiding iingers, automatic means for reversing the Valve and lowering the knife and preferably also the guiding fingers once the knife and guiding iingers have been raised, and automatic moans for closing the valve.

A further purpose in a winding machine of the type described is to employ a rockable iiuid valve connected to the source of fluid pressure and to both ends of the cylinder, having a closed position at an intermediate angle, an rpen position connected to one end of the cylinder at one extreme angle and an open position connected to the other end of the cylinder at an opposite extreme angle, with an exhaust position for each open position connected to the opposite end of the cylinder from that connected to the source of uid pressure, manual means for rotating the valve into the extreme angular position for raising the knife, a fork cam rockably connected to the valve, an abutment travelling up and down with the knife intersecting one fork of the cam to rock the cam to the extreme angular position for lowering the knife as the knife moves up and intersecting the other fork of the cam to rock the valve into the intermediate position to close the valve as the knife moves down.

A further purpose is to moisten the web at or adjacent to the cut end by automatic moistening means operating concurrently with the raising of the knife.-

A further purpose is to employ in a winding machine means operating at the time of cutting for guiding the cut end to the shell on which the web is to be wound and means adjacent to and parallel with the knife, and preferably below the web for projecting a liquid spray on the end of the web being cut at the time of cutting and facilitating carrying of the end to contact with the shell on which the cloth is to be wound.

A further purpose is to operate the liquid spray means by a fluid control valve operated when the fluid means for manipulating the knife and gate is thrown into position for raising the knife and the gate.

A further purpose is to facilitate the winding on a shell of a web or the like which does not respond to moistening by applying at suitable locations on the surface of the shell pressure sensitive adhesive tape having the adhesive exposed and picking up the cut'end of the web by the adhesive.

A further purpose in a winding machine is to employ a rotating drum having a web passing over it to be wound. a shell rotating on the drum above the web, pressure sensitive adhesive tape. secured at suitable locations to the surface of the shell 'with the adhesive exposed outward, means for cutting the web beyond the drum-and permitting it to be'picked up by the shell and preferably also positive means for moving the cut end toward the shell.

Further purposes appear in the specification and in the claims.

, Describing in illustration, but not in limitation and referring to the drawings:

The so-called Simpson type web winding machine (see for example Simpson U. S. Patent No. 542,034, dated July 2, 1895, for Cloth Winding Machine) has become standard in the textile and related industries.

When reference is made herein to a web, it is intended to designate any suitable sheet material similar to or analogous to cloth whether manufactured by weaving, knitting or other textile processes or by sheeting, flocking, extruding, impregnating or otherwise, and whether the basic ingredient is a textile fiber such as cotton, wool, linen, rayon, nylon (linear polyamide), or a plastic or synthetic rubber material such as polyvinyl chloride, or polyvinol chloride acetate, rubber, chloroprene. neoprene, Buna S, Buna N or the like.

The Simpson winding machine is so universally accepted in the art that it will be sufficient to refer those interested to the Simpson patents for the broad outlines of the machine, which in themselves form no part of the present invention.

The frame 30 has bearings 3| (only one of which is shown) for a front drum 32 and bearings 33 (only one of which is shown) for a slightly spaced and generally parallel horizontal back drum 34. preferably at about the same height, as well known. The drums are suitably intergeared and driven in the same direction by means not ,shown as well known.

Suitably above the back drum 34, though normally not directly over its axis, the frame of the machine is extended to provide standards 35 at either end of the drum (only one is shown). which carry vertically movable and slidable pivot jaws 36 (only one is shown) for the axis or center bar 31 of a shell 40 on which a web is to be wound (Figure 1).

It will'be noted that the shell 40, when in the position being described, rests upon the back drum 34 (with the cloth passing from the rear between this shell and the drum) and is rotated or driven from the back drum 34 by that drum.

The jaws 36 are suitably downwardly urged and urged against separation until the shell has been fully wound on the back drum, by means conventionally suggested by tension spring 4l operating on a spring hook 42 on an extension 43 from the lower jaws of the set.

Figure 1 shows the beginning of winding, with the shell 40 on the back drum, and the web 44 just beginning to wind. The term web is intended as a conventional designation of any sheet material, such as textile '(cloth), paper, plastic, etc. which may be wound.

As the roll 45 of web wound on the shell increases in size as shown in Figure 2, the center bar with jaw pivot support moves upward as well known, and it is desired to shift the position from the back drum 34 to the front drum 32. This is readilyaccomplished by hand first by resting the shell on, and allowing the shell to rotate under the action of, both

drums

32 and 34, and then carrying the roll 45 to the position of Figure 3 where it is supported and rotating on the front drum 32 and its axis or center bar is supported at the ends by jaw arms 46 (only one of which is shown) pivoted at 41 on the frame. In this position as well known the web 44 passes over the space 50 between the drums.

Between the

drums

32 and 34 and extending longitudinally of the machine suitably in vertical position I provide a gate 5i, guidedy adjacent its ends in guideways 52 and capable of moving up and down by means later described. At the top of the gate 5I I provide a knife 53 preferably serrated'at 54, and also at the side and preferably below the knife I provide guiding fingers 55. When the knife is in its lower position, it lies below the web when it is passing across from the back drum 34 to the front drum 32, as in Figure 3, but when the knife is raised into its upper position, as shown in Figure 4, it engages and cuts the web at 56 passing across this space above the knife. The direction of the knife is opposite to the direction of progression of the web. In the lower or inactive position of the gate, the guiding fingers 55, which are secured and supported on a shaft 5l rotating on bearings 6U distributed longitudinally of the gate, and spring urged at 6i away from the gate to the position of Figure 6, are held in their closed or inactive position by a deflectlng bar 62, mounted on the frame, and extending longitudinally of the winding machine, between and below the tops of the drums. When, however, the gate is raised, the guide fingers spring out oi the vertical line through the gate as shown in Figure 6, tending to carry the cut end of the web around and back over the shell 40, as shown at 63 in Figure 5, where the web has been severed from the roll 45 on the front drum 32 and a new roll is being started on a new shell on the back drum 34.

In summary, by reference to Figures 1 to 5 inclusive the plan of operation of the winding machine can readily be understood. Thus I show in Figure l the shell 40 in process of winding a web on the back drum 34 while the front drum 32 is inactive. In Figure 2 winding has been completed on the rear drum, and a roll is about to be transferred to the front drum 32, after which a new shell is placed in position to rotate on top of the web passing over the rear drum, as shown in Figure 3. In this position the shell on the back drum is inactive but ready to pick up the cut end and start winding as soon as the cutis made.

Figure 4 shows the gate partially raised, the web being cut, and the guiding fingers beginning to carry the cut end around the new shell. This is completed in Figure 5. -The old shell and its roll are now rotating on the front drum, ready to be removed from the machine.

In accordance with the present invention, lmmediately below the gate I mount a fluid cylinder 64 having a piston 65 and a suitable vertical piston rod 66 connected atv61 to the gate for lowering and raising it. While any suitable fluid medium may be employed to operate the piston, it is provided to use air under pressure with suitable pressure regulation, and air filtration, as well known in the art. A source of air under pressure is shown at consisting of a pipe connection to a suitable compressor, not illustrated. The source of air pressure 10 is connected to a fluid control valve 1|, by means of a port 12. The valve is preferably of a rockable type and has a valve body 13, a valve element 14, a rocking valve stem connected at 16 to the valve element, and a suitable preferably forked cam 11, having one fork element 80. for movement of the valve to down position and another fork element 8| for movement of the valve to closed position.

A pull rod B2 is suitably pivotally connected to the fork element 8| for manual opening of the valve in the position to raise the gate.

The valve body has a port 83 connected by a pipe 84 to the lower end of the cylinder for raising the piston, and also a port 85 connected by a pipe 86 to the upper end of the cylinder for lowering the piston. The valve body also has a port 81 connected to atmosphere for exhaust.

The valve element 14 has a port 90 extending clear through it and an annular slot 9| in one face ending at

points

92 and 93 close to the port 90, but spaced therefrom by a flat sealing portion 94 which seals against the face 95 of the valve body.

The ports connecting from the valve body to the valve element are suitably uniformly spaced from the axis of the valve stem and assume positions in line with the port 90 and the annular slot 9| (Figure 17) in the valve element depending on the valve element angle. In the diagrammatic showing of Figure 11 this slot is not annular.

As seen in Figure 15, a spring 9B behind the valveelement lies in a spring socket 91 and presses against the back of the valve element in a spring socket |00, holding the valve element against the face 86, and in contact at 18 with the stem 15. The valve casing 13 is permissibly split at |0| to provide front and back portions |02 and |03 Joined by bolts |04.

The valve stem is shouldered at |05 to engage in a counterbore |06 of a bore |01 through the front of the valve casing, and is squared at ||0 to receive -a limit cam having a limit cam slot 2 engaging an abutment ||3 in limiting positions. A nut ||4 on the thread ||5 of the stem holds the limit cam in place, and the stem is suitably provided with lubrication means I I6 and lubricant passage ||1. The limit cam is suitably shaped at |20 to receive the cam 11. The valve casing has mounting lugs I2 It is frequently very dimcult to get the cut end of the web to bend around the new shell and adhere to the new shell long enough for one complete wrap of the web to extend around the shell and give a grip to start winding the roll on the new shell. Moistening of the web or the shell to cause adherence to the shell is a difficult operation, necessitating the ultimate in timing with the operation of the knife, if it is to be substantially effective. To facilitate the adherence of the cut end with the new shell, I provide, adjacent the point of cutting and preferably beneath the web being cut, moistening device |22 which is operated in synchronism with the raising of the knife and applies the moistening to the web adjacent to the end at substantially the moment of cutting.

In most cases the moistening agent will be water since this performs the triple function of softening many fabrics so that they are readily guided by the guiding fingers over the new shell, making the fabrics slightly adherent to the shell, and at the same time reducing difficulty with static electricity. In somecases, however, it may be preferable to employ a water solution containing a small amount of adhesive or the like such as gum arabic or boiled starch, or a very dilute glue solution. With certain m-aterials such as plastics, it may be desirable in some cases to moisten with ya non-aqueous solvent, such as benzol, methyl alcohol, or methyl ethyl ketone, or a petroleum hydrocarbon.

It will thus be evident that whenevenpressure is admitted to the lower end of the main cylinder 64 for raising the gate, the liquid valve to the 7 moistener opens and the moistener operates concurrently with the raising of the knife and the guiding ilngers. Whenever the lower end of the main cylinder is cut of! from iluid pressure, the spring |32 can act to close the liquid valve and cut off the liquid spray from the moistener.

n the lower part of the gate, close to a vertical line through the stem of the main iluid control valve 1|, I provide a bracket |42 having an abutment |43 which intersects the forked cam 11 on the stem of the fluid control valve 1|, as is best shown in Figures 19 to 22, inclusive.

Figure 19 indicates the position of the cam when the gate, knife and guiding lingers are in their inactive position, which is the normal position at any time other than cutting. The course of fluid between the inlet port 12 and the cylinder 66 is then cut off at valve 1| by contact of the valve port 90 with the valve body face 85 at |44, and the annular slot 9| connects

ports

83 and 85 from both ends of cylinder 66 to atmosphere through port 81. Liquid valve |28 is closed and the moistener is not operating.

port 81. The gate, knife and guide fingers rise as shown in Figure 4.

As the gate rises, the abutment |43 comes in contact with the fork element 80 of the forked cam 11, moving the valve element 83 clockwise (Figures and 21) cutting off the fluid pressure from the bottom of the main cylinder and lapplying fluid pressure to the top of the main cylinder to return the gate, knife and guide fingers to their lower or inactive position. This is accomplished by moving valve port 90 from connection with valve body port l83 to connection with valve body port 85 (to the top of cylinder 66) and moving valve slot 9| from connection with valve port -85 to connection with valve port 83 and pipe 84.

It will be evident that the pressure in the cylinder is shifted by shifting of the valve as described before the gate has actually moved to the top of its upward stroke (see Figures 2G and 2l). This reversal of pressure in the cylinder in advance of the arrival of the gate at the end of its upward stroke, I find to be very advantageous since kick given to the gate when the pressure is applied to the bottom of the main cylinder is considerable and the inertia of the gate comparatively high, so that the admission of some iiuid pressure into the top of the main cylinder in advance of the completion of the up stroke imparts a desired cushioning action without substantially impeding the velocity of the up stroke. The reversal of pressure as shown in Figure 2l cuts olf the action of the moistener, but here again there is enough delay to complete the moistener action before the Valve |26 can close.

After the gate starts down under the action of the pressure applied to the top of the main cylinder as just described, the abutment |43 strikes `the fork element 8| of the forked cam 11 and moves the forked cam and the valve counterclockwise to the position of Figure 22. and cuts of! fluid pressure from both ends of the main cylinde' connecting both to atmosphere as in Figure The liquid spray from the moistener |23 ceases as soon as the gate begins to return to its inactive position due to the fact that pressure on the liquid cylinder |35 is cut ot! and the spring |32 closes the liquid valve.

It will be noted particularly in Figure 4 that the spray is directed upward and that the guide ngers must guide the cut end upward and around the shell. Where comparatively non-pliable web is used, it is desirable to assist the guiding fingers in accomplishing this rst bend in the cut end. This can be done by introducing the spray under considerable' pressure so that the jets tend to upwardly deilect the cut end and assist the guiding fingers in guiding the cut end around the new shell. The deflecting force imparted by the moisture can, if desired, be supplemented by increasing the number of jets to any extent required.

Certain types of web or the like, and' particularly those made from, coated with or impregnated with plastics, do not respond readily to a moistening action as a means of picking up the cut end of the shell. This dimculty is believed to be due to a combination of factors. Many of these materials are not softened by moistening, or at least are not softened rapidly. The materials are often not rendered slightly adhesive by moistening. Some of these materials are hydrophobic and are not wet by water in the absence of wetting agents. It therefore is important in some cases to nd a supplementary means of bending the cut end around the new shell and causing adhesion to the new shell.

The problem is complicated considerably by the fact that for some time, possibly a matter of minutes before cutting, it must be possible for the new shell to rotate against the web passing over the back drum, and during this period there must be no adhesive action which would prevent free travel of the web past the back drum to the front drum and winding on the old shell which is r0- tating on the front drum. Promiscuous application of paste or adhesive to the new shell or application to the web running between the new shell and back drum during this period immediately prior to cutting would merely result in damage to a considerable amount of the web.

After extensive investigation, I find that there is a comparatively simple solution to this problem. I apply at intervals over the circumferential surface of the new shell strips or other suitable configurations of pressure sensitive adhesive tape having a pressure sensitive surface exposed to the outer covered surface of the roll, as shown at |45 in Figure 6. Immediately prior to the cut this adhesive tape of course adheres to the top of the web every time the shell comes in contact with the web but immediately lets go without damaging the web as the web runs through to the front drum. The only noticeable effect from the presence of this pressure sensitive adhesive tape on the surface of the new shell is a slight noise due to the constant grabbing and letting go which occurs between the adhesive tape on the new shell and the web.

As soon as the cut is made the pressure sensitive adhesive tape holds the web against the new shell and aids the guiding fingers in pulling the web around and engaging it with the new shell to make the first wrap.

The most convenient way to ailix the pressure sensitive adhesive tape to the new shell is to employ tape having a pressure sensitive adhesive surface |48 and |41 on both sides of a backing MB (Figure 23), although it is obvious that the tape could be aillxed to the new shell in some other manner. The tape may desirably be Scotch tape.

The quantity of tape which must be used on the area of the shell depends, of course, on such factors as the stiffness of the web, the adhesive action obtained by the tape, the presence or absence of some beneilt from the moistening, and other fabrics of this kind. In most cases I ilnd it best to use a few strips of the pressure sensitive adhesive tape wound spirally over the shell from end to end in any suitable configuration, preferably in interlocking spirals |50 as shown in Figure 6 having a pressure sensitive adhesive surface exposed at to the web and held in place by the opposite adhesive layer.

In accordance with my invention, I ilnd that the amount of time taken in operating a web winder of the Simpson type can be shortened and the machine can be made more adaptable and more rugged, requiring less maintenance.

In view of my invention and disclosure variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the process and structure shown, and I, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.
