implication fled lovember 88, 1928, Serial No. 150,295, and in Germany December 80, 1825.

My invention relates to a wrapping ma chine for safety razor blades.

It is well known that the blades of safety razor apparatus are packed up by wrapping 6 each individual blade into a cover (wrapper or envelope) provided with suitable print which in its shape corresponds with the shape or configuration of the blade and which is provided with flaps along its sides 10 and ends which are ultimately folded down upon the blade. Usually a suitably shaped lining of oilpa-per or the like is employed besides this outer envelope.

The invention consists of a machine or appliance for folding mechanically paper wrappings about the blades of safety razors. Such a machine attains a high speed, has therefore a large capacity and effects a great economy in labor, while the package is neater 2 than can ordinarily be done by hand.

An embodiment of m invention is illustrated in the drawings alhxed hereto. In the drawings:

Fig. 1, is the machine in plan.

F i 2, is an elevation of the device for feeding t e wrapping sheets and providing them with an adhesive,

' Fig. 3, is an elevation of the device for producing and feeding the lining sheet,

Fig. 4, is a sectional elevation of the mechanism for introducing the blade and closing the wrapper,

Fig. 5, is an elevation of the mechanism for lifting the wrapped blade and conveying the same out of the machine,

Fig. 6, is a front elevation of a detail of this mechanism,

Figs. 7 to 10, are diagrammatic illustrations of the manner of effecting the preliminary creasing of the sheet of paper and introducing the blade into said cover sheet, and

Figs. 11 to 13, are diagrammatic illustrations of one process during the closing of the wrapper.

Like parts are indicated by like numerals of reference in the various figures of the drawings.

Referring to the drawings and more particularly to Figs. 1 and 4, is the driving shaft operated from a suitable source of power. The shaft 30 is journaled in bearings 31 and 32 of the machine framework and transmits its motion by spur wheels 33 and 34 to the shaft 35.

This shaft 35 drives the shaft 38 b means of the bevel wheels 36 sheets of paper by a gearing 200 operated from the shaft 38. The angles 42, 42 extend to the entire height of the pile and are mounted upon rails 44 which in their turn are fixed upon the side rails 45, 45 of the label receptacle.

The withdrawal of the topmost wrapping sheet for the time being is effected by the lifter 4 which is adapted to be raised and lowered and to be moved to and fro between the pile and the hereinafter described feeding device of the machine. The lifting off of the sheet may in well known manner be effected by constructing the picker as a suction head in communication with an air pump. In the embodiment illustrated. the sheet lifter is in likewise well-kn0wn manner designed as adhesive applying stamp so that certain parts of the wrapper are simultaneously provided with an adhesive, for instance in the places indicated in shading at c in Fig. 1. However, in accordance with the special manner of subsequent folding and closing of the. wrapper, the sheet lifter 4 may also be so designed that it provides the wrapper with an adhesive in other places, for instance at the places indicated by the reference letter (J) in Fig. 1 of the drawings.

The sheet lifter is for these purposes provided with four members or arms 4' extending downwards upon which exchangeable gum stamps 4" may be mounted according to the places of the wrapper to be provided with the adhesive. The lifter 4 is mounted upon a slide 47 adapted to be moved longitudinally upon a rail 48 by means of a lever 50 pivoted upon a bolt 49 on the machine framing, and which by means of a pin 51 fixed upon its upper end and journaled in a block 52 engages the sliding track 53 of the slide 47 in the manner of a slot and crank. The rocking motion necessa for the displacement of the slide 47 upon the rail 48 in order to effect the reciprocating motion of the lifter 4,-is imparted to the lever 50-by means of a guide lever 54 from an eccentric upon the shaft 38 against which is drawn in a known manner by means of a suitable spring (not shown) the guide roll 201 of an arm 203 pivoted at 202 and hinged to the guide lever 54.

For the purpose of producing the up and down motion of the lifter 4, an up and down motion is imparted to the rail 48 for which purpose the rail 48 is by the connecting head 55 fixed upon a rod 56 which is vertically guided in the bearing 57. At the lower end of the rod 56 is fixed a block 58 the mouth 59 of which is engaged by the spherical end 60 of an arm 61 which is mounted upon a bolt 62 rotatably fixed upon the machine framing. Upon this bolt is also mounted an arm 63 which by means of a uide roller 64 and a suitable spring (not Shown) is kept in engagement with a cam upon the shaft 38, in such a manner that by the aid of the double-armed lever 63, 61 the rod 56 with the rail 58 is caused to perform an up and down motion at the proper time. To prevent lateral edging of the rail 48, an arm 65 is provided upon-the head piece 58 in the eye 66 of which a pin 67 is fixed which is guided in the eye 67 of the framework of the machine.

The application of the adhesive to the rubber stamps 4" is effected in a customary manner by a roller 68 the shaft 70 of which is journaled in the receptacle 69 containing the adhesive and is continuouslyrotated by means of the sprocket wheels 71, 72 and the chain 73 from the shaft 38.

During its travel from the position shown in Fig. 2 of the drawings across the pile 1, the lifter 4 is raised so far that the rubber stamps 4" take up the adhesive from the roller 68. Above the pile, the lifter 4 is lowered down upon the uppermost wrapping sheet. This sheet adheres to the rubber stamps 4" and is then lifted off when the lifter 4 ascends, whereupon the slide 47 with the lifter 4 is moved into the working position of the feeding mechanism indicated at I in Fig. 1 of the drawings.

The feeding device may consist of a conveyor belt, chain or the like. In the embodiment illustrated, it consists of an intermittently rotated disc 5 which is journaled upon the upright shaft 75 by means of a hollow shaft 74. The intermittent rotation of the disc 5 is'efi'ected in a well-known manner by a Maltese cross indicated at 76 the recesses of which are engaged by a roller 77 upon the crank 78 mounted upon a shaft 79 which is rotated by bevel wheels 80 and 81, Figs. 1 and 4, from the shaft 35.

After the wrapper a has been placed upon the working position I of the disc 5 by the lifter 4, a U-shaped holder or arrester 3 descends upon the wrapper which together with a device hereafter described of the Working place II is moved up and down so that during the ascent of the lifter 4 the wrapper a is retained upon the disc 5 by said holder 3, whereupon the holder is raised and the disc 5 turned through an an le of 60 degrees into the working position I in which, if an inner lining wrapper b is to be employed, this wrapper is placed upon the outer wrapper a.

The lining wrapper b may in a similar manner as described and illustrated for the outer wrapper a be withdrawn from a pile and placed upon the outer wrapper. In the embodiment illustrated, however, the lining is made from a continuous web of aper e pulled off a reel 6, Figs. 1 and 3, w ich by means of the shaft 82 is journaled in arms 83' and 83" of side frames 84 and 84" fixed upon the machine plate F. The web of paper e passes from the reel 6 over an ad justable tension rod 85 between the feed rollers 86 and 87, of which the roller 87 is continuously rotated by a sprocket wheel 88 and chain 89 from a sprocket wheel 90, Fig. 1, upon the shaft 41, while the roller 86 rests loosely upon the paper web. The web proceeds over the table 91 belowa holder 92 and between the .feed rollers 93 and 94, the latter of which is continuously rotated by sprocket wheel 95 and chain 96 from the sprocket wheel 97, Fig. 1, upon the shaft 41.

The holder 92 is by the arm 98 mounted upon a bolt 100 rotatable in journals 99, 99 upon the end of which is fixed an arm 101 engaged by a lever 102. At its lower end, the lever 102 is pivoted upon a doublearmed lever 103, 105 which is fulcrumed at 104 and provided upon its free end with a guide roller 106 which by means of a suitable spring (not shown) is kept in engagement with a cam upon the shaft 41. By this driving device, the holder or arrester 92 is controlled in such a Way that it presses the paper web e against the table 91 and thus holds it stationary every time an end corresponding with the given length of the lining wrapper has been passed through underneath said arrester by the rollers 93 and 94. The piece of the paper web e held between the arrester 92 and the feed rollers 93 and 94 running idle is now punched out by the two punches 106' and 106" corresponding with the angles w and w of two successive lining pieces, the punched out pieces dropping through the recess 107 of the table 91. Simultaneously the punched out lining piece 5 fed forward by the preceding feed motion by the aid of the feed rollers 93, 94 above the outer wrapper located upon the working lace II is severed by the reciprocating knife 108 which cooperates with the stationary knife blade 109. The reciprocating motion of the punching plungers 106, 106 and of the knife 108 as well as of the arrester 3 connected therewith by the arm 205 is efiected by a common head piece 110 fixed upon two rods 111' and 111" which are vertically guided in the eyes 112 and 112' of the standards 84' and 84" and which are directly raised and lowered vertically by cams upon the shaft 41.

The blade could now be placed upon the superposed wralppers b, a and be wrapped up. In order, owever, that the extremely sensitive cutting edges of the blade should not be injured during this process, a special device may be provided by means of which the wrapper is prior to the insertion of the blade scored or impressed along the lines on which the folding of the wrapper is to take pla e subsequently.

For this purpose, notches or folding ralls 112 respectively are provided at the working places, see in particular Figs. 7 to 10, of the conveying device with which folding notches co-operate corresponding edges 113 of a vertically reciprocating punch 9 so that on the descent of the punch 9 by cooperation of the said edges 113 with the said edges or notches 112 the outer and the inner wrapper or, if no lining is provided. only the outer wrapper is scored or creased in the manner illustrated in Fig. 9. In order to hold the wrappers during this scoring operation and to initiate and assist in the operation 1tself. a movably guided presser 115 .is resiliently supported in the punch by means of the spring 116 and has a lead in relation to the scoring knives 113 so that during the descent the wrapper is first pressed against the surface 117 of the die 10 by the said yielding presser 115 and that the scoring knives 113 become operative thereafter. In the same way, the wrapper 1s retained in its correct position by the presser 115 when the scoring knives 113 as'end. The up and down motion of the scoring punch 9 takes place synchronously with that of the cutting knives 106' and 106" as well as of the knife 108 inasmuch as the punch 9 is mounted upon the head piece 110 by the flange 118.

As the scoring knife 113 and the scoring die 10 consist ofsteel, the latter is made by itself in one piece and inserted into a corresponding recess 119 of the conveyor disc or table 5.

During the next motion of the conveyor disc 5 by one sixth of a complete reyolution, the wrappers reach the working position III where the insertion of the blades 7 takes place. This insertion may take place 1n any suitable manner. In the embodiment illustrated, it is effected in such a manner that the blades are conveyed into the working station III by a feed disc 12 and are here picked up by a suction head and placed upon the wrapper.

The feed disc 12 is with its hub 12' journaled upon the pillar 120, Fig. 4, and is intermittently rotated by the s ur wheels 14, 15 and 16 from the hollow s aft 74 of the feed disc 5 in the ratio of 2: 1, so that there exist 12 intermediate positions of the disc 12. In each of these intermediate positions, the disc 12 is provided with two pins 121 each, upon which a blade [is placed by hand with its usual holes.

A suction head 122 serves for lifting the blade off the feed disc 12 and for placing it upon the wrapper at the working station III. The suction head 122 is at 123 in communicationwith an air pump 210, Fig. 3, and is able to move up and down as well as .to perform a swinging reciprocating motion.

For this purpose, the suction head 122 is adjustable in an arm 11 which is mounted upon the shaft 124. The shaft 124 is vertically guided in bearings 125' and 125" by two arms 126' and 126" mounted upon the pillar 120. At the'lower end of the rod 124 is attached a head 127, Fig. 3, engaged by a lever 129 by means of a link block 128. The lever 129 is pivoted upon a bolt 130 and is held in engagement with a cam upon the shaft 41 by means of a guide roller 131 of its arm 132 by the aid of a:

spring 133.

For bringing about the oscillating or rocking motion of the arm 11, an arm 134 is fixed upon the rod 124 which is connected by the aid of a universal joint 135 with a guide lever 136 which is connected by a universal joint 137 with a lever 138 which is pivoted upon the bolt 130 and kept in engagement with a cam upon the shaft 41 by an anti-friction roller 139 and the spring shown in dotted lines.

\Vhen the wrapper attains the working station III, a blade f has also arrived opposite this station, the suction head 122 is lowered down upon the blade f and picks it up, whereupon the head 122 is raised and the arm 11 swung above the working station III. In this position, illustrated in Fig. 10, the head 122 is lowered into the wrapper, releases the blade 7 and is raised again to return into the starting position illustrated in Fig. 1.

After the wrapper with the inserted blade has reached the working station IV by the next rotation of the disc 5, the folding down of the flaps takes place said flaps upstanding in the manner illustrated in Fig. 10 of the drawings. a

This folding down may take place in such lot) . away that first the lining only and subsequently the outer wra per is closed or, as in the embodiment il ustrated, by closing both wrappers simultaneously.

The rocking folders 140' and 140" serve for folding the head flaps a, b of Figure 10 and are mounted upon levers 141 and 141", Figs. 1 and 4. The levers are fixed upon bolts 142' and 142 which are positively coupled by toothed segments 143' and 143' and the common drive of both levers takes place through the bolt 142 which is journaled at 144 and 145 and is controlled by a spring 146 tending to maintain the lever 141, and consequently the lever 141", in the inoperative outer position illustrated in Fig. 1. Upon the lower end of bolt 142' is mounted a lever 147' which under the action of said spring 146 in conjunction with an anti-friction roller is kept in contact with the lateral cam surface of a drumlike eccentric mounted upon the shaft 35.

The folders 149 and 149 which serve for folding over the side flaps a, b Figure 11 are mounted ondouble-armed levers 19 and 20 which in their turn are pivoted upon a bolt 150 of a socket 151, and which at their other ends are connected with the levers 154 and 155 by links 152 and 153. The levers 154 and 155 are fulcrumed upon the pin 156 and are kept in engagement with suitable cams upon the shaft 35 by springs (not shown) and guide rollers, as illustrated in Fig. 4 of the drawings for the guide roller 157 of the arm 158 of lever 154. If the longitudinal edges of the outer wrapper are provided with adhesive at c, Fig. 1, the closing of the wrapper is effected in such a manner that first the front flaps a, b of each side are folded down by means of the folders 140' and 140", and then by means of the folders 149 and 149" the side flaps a" and b" at each side are folded down, so that the side flaps located in front in the direction of rotation of the disc 5 are folded last by the folder 149" of the arm 20.

If, on the other hand, as likewise indicated in Fig. 1, the front flaps are provided with adhesive at (d), the side flaps are first folded down and then the front flaps.

The same folding device may also be employed. if the blade is wrapped up in an outer envelope only and without an inner.

lining sheet. A lateral displacement of blade and wrapper cannot take place, because owing to the box-like folding recess of the die 10 in relation to the other surface of disc 5 a hold is offered in any direction.

During the next rotation of the disc 5 from stat-ion IV to station V the wrapped blade passes underneath a guide or presser plate 22 which prevents the folded wrapper from bursting open. If the longitudinal flaps of the lining are folded separately from and'before those of the outer wrapper,

a plunger 250, Fig. 11, first descends between the scored flaps a, b, a", b so that it retains the flaps a, Fig. 12, while the flaps b" are folded down by the slides 149, 149".

The plunger 250 is mounted u on an arm 251 secured to the upper end 0 a rod 252, Fig. 4, which is guided in the sleeve-like bearing 253 and is operated by the lever 254. The lever 254 is pivoted at 255 and is operated by a cam upon the shaft 35 which acts upon the roller 256 of lever 254.

To prevent turning of the arm 251 in the horizontal plane itcarries upon its extension 257 a pin 258 which is guided in the eye 259. Upon the arm 251 there is furthermore provided above the station V a bolt 260, vert cally slidable, which is locked against turning movement by the flattened collar 261 in the guide 262. At its lower end, the bolt 260 carries a plate of the approximate size of the razor blade and serves for holding down by its weight the flaps folded down at the station IV.'

At the station VI, the wrapped up blade is by means of a lifting device. illustrated in Figs. 1, 5 and 6, raised from the feed ng disc upon the level of a gutter 24 which serves for conveying the wrapped up blades out of the machine. The said lifting device comprises a double armed lever 23 and two blade like plates 271, 271" which are secured to the lower end of said lever 23. The other end of lever 23 is connected by means of an universal joint 272, 273 with a link 274 which in its turn is connected by, means of an universal joint 275, 276 with a driving arm 27 7. Said arm 277 is pivoted at 278 on asuitable socket of the machine frame and is held by a spring 290 with a guide roll 279 in engagement with a cam indicated at 280 of the driving shaft 35.

If by the cooperation of sprin 290 and rotating cam 280 the outer end of lever 277 is drawn downwards, the lever 23 is swung by means of the connecting rod 274 upwards, and the plates 271, 271" will pass through the slots 161, 161" and thereby lift the blade so far that it will, in the uppermost position of plates 271, 271", fall from the preferably inclined supporting edges of said plates 271, 271" upon the bottom of gutter 24 and slide on said bottom out of the machine.

It will be understood by those skilled in the art that various chan 'es and modifications may be made in the lnvention without departing from its spirit or sacrificing any of its advantages.
