Fig. 1 illustrates in diagrammatic fashion how the strip I, which may be ribbon, tape, braid, cord or other material, is fed out in measured length by cooperating rolls 2, 3, is lightly tensioned as by a ring 4, hanging in a loop of the same, passed over a guide roll 5, and thence beneath the guide 6, into the bite of` cooperating gate members 1, 9, on a swinging arm 9. This arm (details of which appear in Figs. 9 and 11) has a movement Which,carries the strip over into the grip of cooperating jaws I0, II, of a Winder mounted on a carrier, which is then indexed to carry the Winder up into the upper position shown. At this station, the Winder is automatically clutched to a turning shaft and caused to thereby rapidly wind the strip into a flat hank, such as\indicated at I2. As the winding of the length of material which has been fed is nearly completed, the arm 9 swings inward toward the carrier on its next stroke, carrying a bight of the strip over into the grip of jaws I0, II, of the next Winder on the carrier head and operates after thus placing the strip in the grip of this Winder to sever the strip as indicated in broken lines at I3.

The Winder is brought to a stop after completing the winding of the hank and the carrier head then advances another step to bring the hank to a transfer station.

While the above described operations are going,

At one station on the guideway, a strip of transparent cover material I3, such as Cellophane or the like, is fed out from a roll or other source, has dabs of adhesive applied'to the underside of the same at I1, in a position to engage solid portions of the cover blank at opposite ends of the windows therein and as this window strip is fed out over the cover blank, it is severed at I9, and the adhesive portions pressed down on the cover blank.

At the next station on the guideway, adhesive is applied by fingers I9 to the four underneath corner portions of the cover blank.

'I'he next step of advancement brings the box blank into position to receive the hank directly on top of the applied window strip. At this station, while the hank is held down. the side portions of the box blank designated 20 and 2l, Fig. 3, are folded up about the edges of the hank and the back flap portions 22, 23, folded in one ,over the other. The adhesive applied to the corner portions of the inner back flap 22 serves for securing the flaps together and the adhesive applied to the corner portions of the outer back ap 23 serves for securing the end flaps 24, of the window strip as'these are folded upward and inward over the back of the package.

The nal result is thus the package illustrated in Figs. 2, 3 and 4, in which the hank of material is fully enclosed and protected within a closely surrounding attractive wrapper or box having the Windows in the front of @the same through which the Wrapped material can be seen and inspected.

The strip I which is to be packaged, passes from a roll or other source (not shown) between gripping rolls 2, 3, Figs. 6 and 7, the upper of which is driven and the lower of which is spring pressed toward the first by being journalled in a lever 25, pivoted at 26, and acted on by spring 21. The driven roll 2 is fixed on shaft 29, Fig. 6,

having at one end a hand wheel 29, by which it may be turned for adjustment or other purposes.

Driving of the measuring and feeding roll 2, is effected by a pulley 30, journalled on the shaft 28, and having a cone clutch element 3l, to match the corresponding cone clutch element 32, Fig. 6, in the adjacent face of the roll 2. The pulley 30, is shifted to engage and disenga'ge the clutch elements by means of a forked lever 33, engaged with pins 34, on a collar 35, rotatably held on the hub of the pulley, said lever being acted on by a spring 36, to hold the clutch normally engaged and having attached to its free end a link 31, connected to the core 38, of a solenoid 39, which when energized will shift the lever reversely, to throw out the clutch.

To prevent over-running of the material, the measuring rolls are positively stopped when the driving clutch therefor is thrown out, by means of a brakeA disc 40, carried by the pivoted lever 4I, Fig. 6, and coned to fit in a similarly conical seat in the face of the brake disc 42, on the end of the roll shaft 28, lever 4I being connected with the clutch lever 33, by link 43, so that the movement of the non-rotating brake disc 40, will be directly opposite to the movements of the pulley and clutch 3D, 3i. In 6, the pulley clutch 3| is engaged to drive the measuring roll 2 and the brake clutch at 40, 42, is disengaged. With energization of the magnet 39, it will be apparent that the pulley clutch will be disengaged to uncouple the driving force and that the non-rotating brake disc 40, will be coupled to the rotary brake disc 42, to immediately stop rotation of' the measuring roll. The magnet 39 accordingly, when energized, is effective to vimmediately stop operation of the measuring rolls and when de-energized, permits the measuring rolls to operate.

To control the stopping magnet 39, there is provided in the illustration, a gage wheel 44, having a rubber or other friction faced rim tracking on the cone 46, at the back of the measuring roll 2, Fig. 6, and carrying a pin 46, which as indicated in the detail view, Fig. 8, will engage the tip of a lever 41, to rock the latter sufciently to carry the contact 48, into engagement with a relatively stationary contact 49. Suitable wiring 50 connects these contacts with the magnet 39. The tail of the contact lever is shown engaged by a spring pressed detent 5|, which will cause this switch lever to snap over from one position into the other, after it is started in either a switch closing or a switch opening direction.

By shifting the gage wheel 44, along the cone 45, Fig. 6, the number of turns which the measuring roll 2 will make before it is stopped, may be predetermined to fix the length of material which will be advanced for each package. For this purpose, the gage or trip lwheel 44 is shown journalled on the end of an arm 52, which can be adjustably secured at 53, along a supporting shaft 54, substantially parallel with the face of the cone. Similarly, the trip lever 41 is indicated as a part separate from the actual switch lever 55, and as adjustably secured at 56, along the shaft 51, carrying the switch lever, which shaft also is substantially parallel with the face of the cone. By setting the trip wheel 44 and the trip lever 41, at diiferent positions along the mounting shafts 54 and 51, the switch may be operated at a greater or less number of turns of feed roll 2 and a consequently greater or less length of stripimaterial be fed.

The switch described is thus closed to stop the strip feed for each rotation of the trip wheel 44. To open this switch, a link 58 is extended from an arm 59, of the switch lever 55, back to a trip lever 60, Figs. 5, 9 and 11, pivoted at 6|, and carrying an inclined detent tooth 62, adapted to be picked up by a pin 63, on the back stroke or outward movement of the swinging arm 9, which carries the strip into the bite of the spinner on the carrier head. In the inward movement of the arm 9, Fig. 9, the pin 63 will ride over and take a position behind the inner face of the spring pressed tooth 62, Fig. l1. Then upon outward movement of this arm, this pin will rock the upper end of trip lever 60, outwardly to thereby pull the rod 58, inwardly causing the latter to rock the switch lever back into the open circuit position indicated in Fig. 8.

The belt 64 which operates the feed roll pulley 30, is shown in the general plan view, Fig. 5, as running from a pulley 65, on shaft 66, driven by chain and gear connections 61, from a reduction gear box 68, coupled by shafting 69, to motor 10.

Winding mechanism Upon a horizontal shaft 1 I, carried by a standard 12, Figs. 9, 11, 13, there is rotatably mounted a three-armed carrier wheel or head 13, and on the arms of this carrier are mounted the socalled winders or spinners which take the strip and wind it into flat hank form.

This car'rier is indexed to carry the winders into receiving, winding and delivering positions by the drive gearing shown particularly in Figs. 9, 13 and 14, and comprising a chain 14, operating from sprocket 15, over apin'ion sprocket 16, carrying spur pinion 11, in mesh with spur gear 18, which as illustrated in Fig. 13, is loose on the hub 19, of the carrier head but is frictionally coupled to this hub and to the back of the carrier by friction washers 80, 8|, between opposite sides of said gear element and the hub flange 82 and the back of the carrier. In the particular showing in Fig. 13, the carrier head is slidably keyed on its hub at 83, and is pressed backward to yieldingly engage these clutch elements by a spring 84, about the hub, interposed between the face of the carrier and an adjustable screw abutment 85, on the outer end of the hub. This frictionally coupled form of drive permits the gear 18, to run continuously and the carrier head to be turned intermittently as permitted by the control mechanism now to be described.

Each arm of the carrier head is shown as having a lug or tooth 86, adapted to ride over a spring tensioned dog or pawl 81, Figs. 11 and 14, into engagement with a xed tooth 88, on the end of a holding lever 89, pivoted at 90, and yieldingly supported in the carrier holding relation by spring 9|.

This latch or holding mechanism is linked up with the swinging strip placing arm. 9 so that upon the outward retreating movement of this arm, the carrier head will be freed and permitted to rotate to the next station.

This is accomplished in the illustration by providing an arm 92, on the end of rock shaft 93, which carries the swinging arm and by providing on the arm 92, Figs. 9, 11, 13, 14, a spring pressed hook 94, to pass up over a pin 95, on the holding lever 89, on the inward stroke of the arm 9, and on the outward stroke of this arm to pull the holding lever down far enough to release the tooth 88, from lug 86. Because of the difference of centers 90, 93, the hook 94, will release pin 95, after lever 89 has let go of the carrier lug 86, permitting lever 89, to snap back upward into position ready to catch the lug 86, on the next arm of the carrier. Lever 89 is shown as having a stop 96, located at the far side of the center 90, to properly limit the return movement of said holding lever.

Movement is imparted to the swinging arm 9, in the illustration, by means of a rocker arm 91, on the rock shaft 93, connected by link 98, to a lever 99, actuated by cam |00, Fig. 9.

The winders are alike and consist in each instance of a hub i0| carried by a spindle |02. freely journalled at |03, Fig. 13, in an arm of the carrier, said hub carrying strip holding and reeling devices and the spindle carrying at the backa frictional clutch member |04, engageable by the rotating disc |05, on the end of a shaft |06.

This shaft |06, Fig. 13, has a longitudinal clutching and unclutching movement in the rotary bushing |01, and is yieldingly clutched to that bushing by spring |08, engaged between a flange |09, on the end of the shaft and a clutch washer ||0, pressed by said spring against the adjacent end of the bushing. Figs. 9 and 14 illustrate how rotation is imparted to the bushing |01, by means of a sprocket pinion on the outer end of the bushing over which passes the chain ||2, Fig. 5, down to a driving sprocket H3, on the gear box 68.

The shaft |06 is shifted inwardly to drive the Winder as in Fig. 13 by means of a walking beam lever H4, pivoted intermediate its ends at ||5, having an adjustable abutment ||6, at one end engaging the end of shaft |06, and engaged at its opposite end by a push rod ||1, slidingly mounted in a bearing ||`8, in the supporting standard and carrying the roller H9, engageable by the cams |20, Fig. 14, on the back of the carrier head. As will be clear from Fig. 14, these cams are positioned to rock the lever H4, and effect the driving relation shown in Fig. 13, when a Winder spindle on the carrier comes into register with drive shaft |06 and the carrier is locked in this position.

Details of the strip holding and supporting portions f the Winder appear in Figs. 15, 16, 1'1, 18, where it will be seen that the hub portion |0I, carries outstanding arms |2I, |22, provided with opposite and inwardly tapering strip supporting posts |23, |24. Cooperating with the iirst of these posts |23, is a spring pressed holding finger |25, pivoted at |26, and having an extending arm |21, adapted in the rotation of the Winder, Fig. 9, to strike an abutment |28, which effects the release of this finger from the holding post |23, each time the latter approaches and crosses the line of the strip being wound, at the top in Fig. 9.

The gripper for holding the inner end of the strip consists in the illustration of a fixed outwardly projecting j aw |29, intermediate the posts |23, |24, and a companion jaw |30, pivoted at its inner end at |3|, Fig. 16, and normally held in the jaw closed relation by the shoulder |32, of a slide |33, acting on the inwardly extending tail portion |34, of said movable jaw, this slide being acted on in a jaw closing direction by a spring |35. A shoulder |36, on slide |33, opposite the shoulder |32, by acting on the angularly projectin'g lug or tail portion |34, serves to throw the jaw open to the dotted line position of Fig. 16,

when the slide is forced inwardly. As shown most clearly in Fig. 15, the jaws may have a mating or tongue and groove engagement one in the other as at |31, to insure firm grip on the strip material.

Opening of the jaws on the Winder to take hold of the strip is effected as a part of the movement of the swinging arm 9, which deiiects the strip inwardly into the plane of these jaws. For the purpose, there is provided on the swinging arm 9, Figs. 11 and 15, a pivoted spring pressed dog or pusher 38, which in the inward movement of the swinging arm engages an end portion |39, of the jaw opening slide to force this slide inward far enough for a hook |40, on the same to catch behind a spring pressed detent |4|, which will temporarily hold the slide in the jaw open relation while the pusher |38, slips on past the corner of the shoulder |39, as indicated in broken lines, Fig. 15.

While the jaw |30, is thus fully open as in broken lines Fig. 16, the strip engaging edge |42, Figs. 9 and 13, on the swinging arm 9, has deflected the strip inwardly against the xed jaw |29. As this takes place, an abutment |43, Figs. 9 and 11, forces back the spring detent |4|, releasing the slide |33, and thereby causing the movable jaw to snap closed on the'strip against the xed jaw.

While these several operations are taking place, the Winder is locked on the carrier head in the position shown in Fig. 11, and at the bottom in Fig. 9, with the generally at faces of the jaws |29, |30, substantially parallel with what will be the inwardly deflected portion of the strip,

Fig. 1. Securing of the Winder in this relation is effected in the illustration by a locking slide |44, operating in a guide |45, Fig. 11, in the carrier head and engaging a locking notch |46, in the hub of the Winder.

The slide |44 for locking each Winder is controlled by a rocker arm |41, Figs. 11 and 13, projecting from the back of the carrier into an opening |48, in the slide, said rocker arm being on one end of a short rock shaft |49, journalled.

at |50, and carrying at the opposite enda rock lever |l. The latter as indicated in Figs. 13 and 14 is acted on by a spring |52, applying its force to cause the locking slide to be thrust inwardly into holding engagement with the hub of the Winder.

Release of the slide |44, which holds the Winder, is effected at the upper, winding station as indicated in Figs. 13 and 14, by having the inclined nose |53, of the slide controlling rock lever |5|, vride up over a stationary shoulder or abutment |54.

To lock the Winder again after a hank is wound on at the upper, winding station and to prevent the head from turning before this operation is completed, the carrier head is permitted a slight movement after the locking lever 89, Fig, 14, is pulled down to release the head. At the moment the carrier is thus unlocked, the frictionally coupled gearing at 18, 80, 8|, starts to turn the carrier, but such movement is almost immediately checked by a hook |55, on rock lever |5|, coming in engagement with a stationary shoulder |56. This movement however, is sumcient to permit the inclined nose |54, at the opposite end of this rock lever to drop down over the edge |51, of abutment |54, which permits this lever to rock under the force of the spring |52, as soon as the notch in the then rotating Winder comes into register with locking slide |44, which thereupon snaps into holding engagement with the Winder. The movement thus oc curring from engagement of the slide in the locking notch permits the lever |5| to rock far enough to shift the hook from behind the stop shoulder |56, which leaves the carrier then free to turn under the drive of the friction gearing on to the next station.

Strip severing means The swinging arm 9, after carrying the strip inwardly, opening the movable Winder jaw |30. and then permitting that jaw to snap closed on the strip pressed against the fixed jaw,- effects the cutting of the strip at a point just above the gripper jaws.

Figs. 9, 11 and 13 show that the swinging arm 9 carries a lever |58, pivoted at |59, and having a slotted and inwardly angled upper end |60, receiving the shank of a screw or stud 6|, on the outer end of a shear blade |62, pivoted on the swinging arm at |63, in cooperative relation to the fixed shear blade |64. 'Ihese blades are angled as illustrated to make a bias cut approximately as indicated at` I3, in Fig. 1, and as the arm 9, swings inward in Fig. 9, the movable blade will pass beyond the strip, ready to close against the inner face of the strip as in Fig. 11.

The closing of the shear blade to cut the strip is effected as the arm 9 approaches its inner position by the pin |66, on the lower end of the blade lever |58, coming into engagement with and passing along the stationary inclined cam or shoulder |61 and by the lever |58, contacting an abutment |65, Fig. 11, which serves in the
