-To THE mi!! En. BESSER, s'rUTTGAn'r-cANNsTATT, GERMANY -ASSIGNOR rnnnnw 'AND GUMMING MACHINE Application-mea laren v, 192s. serial no llhis invention relates to the machine for wrapping up razor blades forming the ob- ]ect oi my prior Patent Number 1,685,601 issued September 25, 1928, and more particularly tox modilications of those mechanisms which serve for feeding the wrappers into the machine and applying the adhesive to them, as well as for discharging the Wrapped up blades from the machine.v f

The improved mechanisms are illustrated in the accompanying drawings, by way of example.

Fig. 1. shows a. plan of those parts of the razor blade enveloping machine according to my said prior patent application to which the present improvements are essentially applied,

Fig. 2 illustrates in detail the modified mechanism for-'feeding the wrappers into the machine and applyingV the adhesive to same, as well asthe drive for the modified mechansm for discharging the wrapped up blades from the machine, in elevation,

Fig. 3 is a. front elevation of Fig. 2 viewed from the left, the pile of`wrappers and the device for raising a wrapper from the pile omitted for the sake of clearness,

Fig. 4c shows in detail the discharging device in elevation,'and

Fig. 5, the same in front-elevation.

The paper wrappers a areas in my prior Patent 1,685,601, piled up in a pil e 1 in a frame-like container of the customary and,

Below the front iiap of a; suitable suction device,

for a suction nozzle 3 is adapted to oscillate between this flap anda roller 6. VThe dit bil

f said nozzle 3 is secured in a. shaft 4 communicating by a with an airpump 7 driven and confrom the driving shaft 38. The oscillating or rocking motion is imparted to the hollow shaft 4 by an arm 8 suitably mounted upon it, a connect-- ing link 9 and a double-armed lever 10 pivoted upon a bolt 11 and kept in engagement with a suitable cam or eccentric 100, see Fig. 3, o the driving shaft 38, by mea-ns of a bowl 13 and spring 14.

llfhe roller 6 is journaled in the pedestals suction pipe rotary hollow hosepipe 259,825, and in Germany Hatch 18, 1927.

12 by ly rotated by a spur wheel 16 meshing with the spur Wheel 19 keyed to the shaft 18. The `shaft-18 is driven by a spur Wheel 35 from the spur wheel 102 upon the shaft 27, see Fig. 2, which is continuously rotated by means oi a sprocket wheel 28 and a chain 29 from a sprocket 4 wheel 30 keyed to the sh aft 38. The chain is kept under tension by a sprocket wheel 31 mounted upon the pin 32 of a rocklng arm 33. The roller 6 is provided with an 'annular groove 6- or the entrance of the suction nozzle 3 and cooperates with a roller 20 which isadapted to be swungv from the position shown in dotted lines in Fig. 2 into the operative position back again. The roller 20 is adapted to ro-A tate loosely in two ydouble-armed bearin levers 21 which are mounted upon a sha- 22 journaled in the pedestals 12. One of these arms is kept in engagement with the cam 25 keved to the shaft 18. by means of a friction bowl 23 .and tension springs 24 attached to the free ends of the levers 21.

For withdrawing the lowest paper wraplper from the pile, the suction nozzle 3 is in the position shownlin ull lines and the oscillating roller 20 in the osition shown in dotted lines in Fig. 2. er the front ap'of the lowest wrapper has been attracted by the suction nozzle 3, this nozzle is swung into the position indicated in dotted lines in Fig. 2, entering the recess 6 and simultaneously the roller 2() is moved by its described .controlling device into the osition shown in full lines, whereby the ont flap of the paper wrapper is forced by means of said roller rotated roller 6 and the wrapper completely drawn oil the pilel and conveyed to another pair ofr feed rollers 26dandg3l, The roller 26 preferably serves'as'adlsive applying drum-if desired-and is mounted u on e above mentioned shai't` `217 journaledin the pedestals 12. The adhesive applying rolleror cylinder 26 is provided, with* suitably shaped and arranged projections or ribs at those places where adhesive is to be' applied tothe flaps of the passing wrapper.

means of ashaft 15 and is continuous- I shown in full lines, and Y in the roller 6,

20 against the continuously plying roller by the other roller 34 continuously rotated y the previously mentioned spur Wheel 35 from the spur wheel 102 of the shaft 27 of the adhesive applying cylinder. The adhesive. is applied to the adhesive applying cylinder 26 by the roller 36 continuously rotated by a spur wheel 103 from the spur wheel 102 and which picks up the adhesive from the box 37 filled with a suitable adhesive. If it is not desired to apply adhesive to the wrapper, the cylinder 26 and counter drum 34 may be used as simple feeding rollers.

After the wrapper has passed the adhesive applying drum 26 and has been provided by said drum with the adhesive at the desired places, it is fed forward on the rotary feed table 105 by means of fingers 138 adapted lto oscillate in the direction of the feed. The said fingers 138 form parts of a plate-like piece 139 (Fig. 3) which is secured to an ai 1n 140 rotatably mounted at 141. Oscillation of said arm 140 is effected and controlled by means of a lever 142 which is pivoted on bolt 143, connected by link 144 to said arm 140 and.

held with a bowl 145 in contact with a suitable eccentric 146 keyedI upon the driving shaft 38, by means of a tension spring 147 attached to an arm-like projection 142 of lever 142. When the wrapper a has passed underneath the cylinder 26, the. two fingers 138 engage the two lateral flaps of the wrapper from the rear and push it into the position shown in Fig. 2 on to the turntable 105, two angles 170 effecting the lateral guidance of the wrapper. In this position, a holding plate 104 mounted upon a block 39 is lowered on to the wrapper, as described in my prior Patent 1,685,601. The block 39 is guided in a stationary guide member 42 by means of the rods 40, 41 and is under the action of comression springs 43 tending to force the block 39 and thus the holder 104 downwards. For the purpose of controlling this motion, an arm 45 engages a slot in the block 39 by means of a pin 44. This arm 45 is suitably fulcrumed at 46 and kept in engagement with a cam 49 keyed to the shaft 27 by means of a bowl 48 and the said compression springs 43.

.The discharge of the wrapped up ,blades is effected by a U-shaped plunger 50 which is guided vertically by means of the rod 51 in a bushing 52 attached to the frame of the machine. The plunger 50 projects with its vertical limbs through openings 53 in the dies 110 of the turntable 105. The plunger 50 has its up and down motion imparted by an arn 55 pivoted by means of the shaft 56 and engaging by means of a sliding block 57 the notch of a slotted block 58 mounted upon the rod 51. The arm55 receivesits oscillatinor motion by a double-armed lever secured to said shaft 56, one arm 150 of said lever being with a cam kept with a bowl 153 in contact keyed on the shaft 18 by means of a spring 152 attached to the end of the other arm 151 of said lever.

Above the discharging station there is provided a collecting box 58 forming a vertical channel which corresponds in its dimensions substantially with the rectangle formed by the wrapped up blade lc. At the lower end of this collecting box'58 ngers 60 project slightly into the free channel, said fingers being preferably bevelled inwards below at 61 to facilitate the passage of the blades. The fingers are mounted on lateral projections 63 of the box 58 by means of pivots 62 upon which are fixed arms 64 pulled towards each other by a spring 66, so that the fingers 60 abut resiliently against the lower edges of the box 58 inthe manner shown in Figs. 4 and 5 of the drawings.

IVhen the wrapped Vup blade is pushed upwards by the ascending plunger 50, it is conveyed from the die 110 into the aperture of the collecting box 58, the blade compressing the fingers 60 outwards to the desired extent, whereupon the fingers 60 fly back behind and below the blade and retain it when the plunger 50 descends again. This arrangement has the -advantage thaty a bursting-open of the blade wrapper flaps is prevented by the piled up blades and the counting and packing of the wrapped `up blades 1s facilitated.

Various changes and modifications may be made in the details of the invention without departing from its spirit, and I desire, therefore, that only such limitations shall be placed thereon as are 'imposed by the prior art. I claim as my invention In a machine for feeding wrappers from a pile, a suction nozzle arranged beneath said pile and adapted to attract the front end flap of the lowermost wrapper and convey it beyond the pile, a pair of feed rollers one thereof being mounted to swing and press the front end flap of the wrapper against the other feed roller, a second pair of feed rollers into which the wrapper is fed by the first feed rollers, and fingers arranged at the rear of the second feed rollers to feed the wrapper after the latter passes between said second rollers, one roller of the second pair being an adhesive carrying roller to apply adhesive at predetermined places on the wrapper while the latter is being fed between the second pair of rollers.

In testimony whereof I have affixed my signature.

PAUL GANGLER.
