chine which will quickly. seal an ediblearticle, so as to hermetically seal-the contentslthercof from the atmosphere.
Another object of theinventionis. to provide a sealing and cuttinghead: which in a. single operation crimps theedges of thexsealingpaper such as cellophane around the outer circumference or edge of the'confection, and as. part of the operation, trims the material aroundisaid edges.
Yet another object of the; invention is to. provide a sealing and cutting head' whereby in a single operation the layers; of thepa'perabove and below the article arecaused't becrimped and sealed and simultaneously trimmed about the circumference-of the article. 7
A further object of the invention is to provide airinge of crimped paper which extends in substantially the same lane as lthegplane of the' top surface of the confection afterthetrimmingoperation has taken place.
Additional objects will be found. throughout the specification.
In the drawings, I 1 Figure 1 isaperspective wiewtofi the head in position for receivingzan article to be wrapped.
Figure 2 is a vertical?sectionthrough tlie center of the headwith parts showninperspective.

that may be connected to anysuitablesource of The sleeve l'is adjustably:supportedl on the stationary support rod 2 by screw bolts 3.
Extending from the-sleeve-is an arm 4 'for supporting the upper. section A. This'sectionhas anupperportion 5, and attached below the shoulder -6-is a cutting ring I which: is removably attached to upper portioni by one or more screws 8 as seen in Figure2.
. The lower end of the. cutting ring; isprovided with a beveled portion =97 which ends in. a cutting edgefll). r
Mounted within the space .H. formed bythe ring 1 isa former I2. This-former, is moved downwardly by one or more :coiled-springs-fas indicated bytheinumeral w. The lower ends of these springsare seated inlrecesses M in the former and their upperends, bear against-the .flat
under side. I 5 ofthe uppenportioni. The-springs continuously force Ithe former in- -adownward direction. Downward movement however, is
arrested by rod l6. The'stop'rod 1.6,, whichis provided witha head I'l that seats. in a lower recess I8, of former I2.
There. is an additional lower recess l9 for heatingplate 20 as shown 'in Figures 2 and .5.
the space I I.
Preferably. spaced 'circumferentially about the stop rod [6 area plurality of.-heating rods.-.22.
The lower ends ofthese rods:exten'dsubstantially to heating plate 20, and..they-are.fixed to'the formen-so that'theytoo ifloat with theiormer in space H. In doing so, they. slide in recesses 23 in upper portion 5. The-heating rods are'pro- 'vided with heads 24, andisaid heating rodsiare also provided with suitable electric'conductors 25 electrical potential, not shown.
The floating former l2v istprovided with .a circumferential'series :of teeth. 26 which aextend from the lower. peripheraledge. upwardly which I terminate. at the shoulder :21. These zteeth'have horizontal extensions 28. ThGSB hOIiZOHtBJ- GX- tensions terminate at the additional lower re- :cess- I9.
It willbe'rnoted that therlowerinnerperiph- 5 is serrated.
. circumferential paper extensions.-
. extensions have been indicated by the Figures 6 and 7.
- Following this operation the lower sectionde- The entire upper section A is stationary except the floating former l2 and the springs l3 and heating rod 22 that move with it, during the upward movement of the lower section B now to be described.
This lower section is also provided with teeth 30 which extend peripherally around the lower section. These teeth have horizontal extensions 3| which mesh with horizontal extensions 28 during the forming operation! Sin'ce'the horizontal portions 28 of teeth 26 mesh with horizontal portions 3| of teeth 30, the cutter's inemail teeth 29 may ngage teeth so when the 1 former has been caused to move upwardly by the upward movement of the lower section B.
A stop rod 32 is provided for the lower section having a head 33 which is adapted to be moved into the recess 34 of said lower section, as-the' pie to be sealingly wrapped when the upper and lower sections A and .3 come in contact with each other, and the cutting edge. 10 moves past or reaches the junction line 50 of the series of vertical teeth 29 and teeth extensions 30 of the lower section. Former teeth 26 mesh'with cutting ring teeth 29 at. all positions'of the parts.
The lower section may be heated by any suitable means such as the circular heater 36 that is located in the recess 3'1. -Thisheater is provided with a conductor 38 that may be connected to the same potential "as the conductors 25..
' In-operation, a series'of unwrapped piesmay be fedrone after the other, to the head,- but first,
- each pie hasbeen fed into'a loop-of cellophane so that the cellophane extends atthe top and bottom thereof, or conversely, separate sheets of cellophane may be fed with the pie to the head. This operation'may be done either manually or may be performed by suitable mechanism, not
' shown. There are various machinesfor feeding articles and papers together to a forming head and the present invention is not concerned with such-machines, as see Hausheer Patent -No.
2,232,783, February 25; 1941.
Once the pie has been positioned withth paper-both above and below it'on the head 33,
. the lower section B of the head is moved upwardly. At this time the head 33 of rod 32 is about level with the lower edge of the slantin sides 35. The lower section moves upwardlyuntil teeth 28- engage teeth 3| in meshed relationship rand cause former 12 to move upwardly within space II.
This action continues until teeth 29 abut teeth 30 whereupon the cutting edge reaches or'passes the junction line of teeth 30 and slanting sides 35, a sealing and crimping action takes place to seal the two layers of paper and crimp. them; Substantially simultaneously the cutting edge I0 severs the crimped and joined These paper letterEin scends, by a suitable mechanism, not shown. The
Iti will be noted that the vertical aetszmj the Qcutting ring, and the :vertical :andhorizontal teeth on the former and lower section B cause proper crimping of the extension E of the cover and that these teeth also perform the Very important dual functions of completely sealing the edges of the sheets of paper which form this extension so as to seal the article, and properly guide the former and lower section with regard to each other as well as the cutting ring on the lower section B.
It should 'be'understood'that other 'g'uide means may be used than the vertical and horizontal teeth shown, and that the particular width of these teeth is of no consequence except that they shouldmesh with each other so as to prevent relative movement between the parts when the upper and lower sections of the head are in engagement. It should also be understood that it is. not desired to limit this invention to the exact construction shown as the shape of it may be changed according to the shape and size of the confection to be wrapped.
:The description and drawings are therefore to be construed. in anillustrative rather than a limiting. sense, :as I desire to be limited only to the .extent set forth by a reasonable interpretationaof the appended claims.
I claim:
