Fig; 15 is a diagrammatic view of an' electricj circuit including means for heating folding devices,; heat sealingrollers, and wax containers shown in preceding Referring to the drawings, wherein like reference' characters designate like parts throughout at the rear thereof and journalled in suitable clutch part 21 with, and disengage the several views, v5 and 6 indicate the side frames of the machine, which are connected together by cross members 7 and have legs 8 that are bolted or otherwise suitably secured on the machine foundation 9. The various movable parts of the machine are mounted on the above described framework and said parts are preferably driven from a common source of power, herein shown as an electric motor 10 which is bolted or otherwise suitably secured on the side frame 5 at the bottom thereof. This motor 10 is supplied with current from any suitable source, and said motor. may be stopped or started, as desired, by a suitable switch (not shown).
Fixed on the armature shaft 11 of the motor 10 is a pulley 12 around which passes a belt 13. The belt 13 also passes around a pulley 14 which is fixed on one end of a shaft 15 that extends transversely of the machine, and is journalled in suitable bearings on the side frames 5 and 6 thereof. Fixed on the opposite end of the shaft 15 is a pulley 16 around which passes a belt 17 the tension of which is regulated, as desired, by a tension roller 18 mounted on the side frame 6 of the machine in any suitable manner. The belt 17 also passes around a pulley 19 that is fixed on a shaft 20 extending across the machine at the top and rear thereof and journalled in suitable bearings on the side frames 5 and 6. This shaft 20 constitutes the main drive shaft of the machine, and said shaft is continuously driven through the described driving connections therefor with the motor 10.
Mounted on the shaft 20 is a clutch of any suitable type including a part 21 which is splined on said shaft to rotate therewith and move therealong, and a part 22 which. is loosely mounted on said shaft and rotated thereon upon engagement of the clutch parts 21 and 22. The clutch part 21 is moved into and out of engagement with the clutch part 22 by a lever 23 which is pivoted at 24 on the framework of the machine. The lever 23 is pivotally connected at 25 with a rod 26 extending transversely of the machine through suitable bearings on the side frames 5 and 6 thereof. This rod 26 is provided at its opposite ends with knobs or handles 2'7 by means of which the rod may be moved to swing the lever and engage the said part from, the clutch part 22.
The clutch part 22 has secured to, or formed integrally therewith, a pinion 28 which meshes with a gear 29 that is fixed on a shaft 30 extending transversely of the machine and journalled in suitable bearings on the side frames 5 and 6. This shaft 30 also has fixed thereon a pinion 30 which meshes with a gear 30" loosely mounted onthe shaft 20. The gear 30" has secured thereto, or formed integrally therewith, a sprocket 31 around which passes a chain 32 that also passes around an idler sprocket 32' Journalled and adjustably mounted in any suitable manner on the side frame 5. The chain 32 also passes around a sprocket 33 which is fixed on a shaft 34 extending transversely of the machine bearings provided by brackets 34 bolted or otherwise suitably secured on a spacer 34" between conveyor ways 39. The shaft 34 also has fixed thereon sprockets 35 around which pass chains 36 which extend longitudinally of the machine between the side frames 5 and 6 and pass around sprockets 37.
The sprockets 3? are fixed on a shaft 38 which extends transversely of the machine and is Journalled in suitable bearings provided by brackets 37' bolted or otherwise suitably secured on the front ends of the ways 39. The ways 39 project forwardly from the frames 5 and 6 and extend longitudinally of the machine between said frames. These ways 39 are bolted or otherwise suitably secured to certain of the cross members 7 which extend between said ways. The chains 36 and a plurality of carton forms carried thereby, are thus driven continuously from the shaft 20 when the clutch parts 21 and 22 are connected by the described means for this purpose. The forms 40 are secured to, or have formed integrally therewith, base plates 41 which are fastened to the chains 36 in any suitable manner at intervals along the same. During travel of the chains 36 and the forms 40, the base plates 41 of the latter are received in suitable guides 39" on the ways 39 and which serve to guide the forms and maintain them in proper position.
In accordance with the present invention, blanks 42 (Figs. 1 and 4) are fed into the path of travel of the forms'or supports 40 and formed into containers thereon by mechanism including movable means for folding and heat sealing said blanks. These blanks may be of paper or other suitable material impregnated with, or having applied thereto, a substance which upon application of heat to overlapping portions thereof, will be effectively sealed through the medium of said substance. As herein shown, blanks 42 of waxed paper are employed in the making of bags or liners A (Fig. 9) that are formed on the supports or forms 40, and said blanks are fed into the path of travel of said forms by mechanism such as disclosed in Patent No. 1,674,920, granted June 26, 1928, to G. A. Robinson.
Accordingly. the shaft 38 has mounted thereon, a sprocket 39 around which passes a chain 40' that passes under an idler sprocket 41' which serves to regulate the tension on said chain and is journalled and adjustably mounted in any suitable manner on the side frame 6. i'.he chain 40 also passes around a sprocket 42 which is fixed on a shaft 43 extending transversely of the machine and journalled in suitable bearings on the side frames 5 and 6. Loosely mounted on the shaft 43, and driven from said shaft through a suitable clutch 38' (Fig. 4) thereon, is a sprocket 43' around which passes a chain 44. This chain 44 also passes around a sprocket 45 which is fixed on a shaft 46-extending transversely of the machine and journalled in suitable bearings on brackets 4'7 that are bolted or otherwise suitably secured to the side frames 5 and 6 at the top thereof (Fig. 1). This shaft 46 has fixed thereon a roller 48 provided longitudinally thereof on its circumference with a groove 49 (Fig. 7). The shaft 46 also has fixed thereon a pinion 50 which meshes with a gear 51 that is fixed on a shaft 52 extending transversely of the machine and journalled in suitable bearings on the brackets 47.
Fixed on the shaft 52 is a roller 53 provided longitudinally thereof on its periphery with a cutter 54 which enters the groove 49 of roller 48 during each revolution of the latter and the roller 53. Fixed on the shaft 46 at the end thereof opposite that carrying the pinion 50, is a gear 55 which meshes with an idler gear 56 that is journalled on one of the brackets 47. This idler gear 56, in turn, meshes with a gear 57 that is fixed on a shaft 58 extending transversely of the machine and Journalled in suitable bearings on the feed roller 60 is driven by gears 57, 61- fixed on shaft 58 and meshing with gears 61" fixed on shaft 61. The upper feed roller 60, the lower feed roller 59, the roller 53 and cutter 54 thereon, and the roller 48 are thus driven continuously through the described driving connections therefor with the shaft 38.
Bolted or otherwise suitably secured to the machine foundation 9, are frames 62 (Fig. 1) that carry vertically extending supports 63 the lower ends of which are bolted or otherwise-suitably secured to said frames. The upper ends of the supports 63 are secured in any suitable manner to corresponding .ends' of horizontally extending supports 64 the opposite ends of which are secured in any suitable manner to the brackets 4'7. Journalled in suitable bearings on the frames 62 'isa shaft 65 on which is mounted a roll 66 of waxed paper. A web 67 from this roll is led upwardly around a roller 68 onthe supports 63, then horizontally around a roller. 69 on the supports 64, and then downwardly and horizontally be- :tween the feed rollers'59 and 60 from which the web is led horizontally between the rollers 48 and 53. The :web is then guided downwardly by guides 48 between the roller 48 and pressure rollers "70 cooperating therewith, said pressure rollers being mounted in any suitable manner on a vertically extending plate '71 which carries said udes.
The plate '71 is bolted or otherwise suitably secured to the side frames 5 and 6 and. the brackets 4'7, and said plate is provided near the bottom thereof with an opening "72 through which the plate 11 and the guides '73, whereupon the cutter 54'cuts a blank 42 from said web at thetime the leading edge of the web is seized between low speed rollers 75 .and pressure rollers '76 cooperating therewith. The low speed rollers '75 are-fixed on a shaft 7'7 extending transversely of the machine and journalled insuitable bear? ings on the brackets 47, said'rollersand said shaft being driven by a sprocket '78 fixed on the latter and over which the chain 44 passes. The ressure rollers '76 are mounted on the plate "71 in any suitable manner and extend through suitable openings in said plate for engagement with the blank 42 and thelow speed rollers '75. The blank 42 is fed downwardly by the low speed rollers 75 and the pressure rollers "76, between high speed rollers '19 and pressure rollers 80, said high speed rollers being fixed on a shaft 81 journailed in suitable bearings on brackets 82 that are bolted or otherwise suitably secured to the side frames'5 and 6 at the top and corresponding end portions thereof.
84 that also passes around a'sprocket adwhich is blank is coated or impregnated.
The high speed rollers are v driven throughthe medium of a sprocket 83 fixed on the shaft 81 and around which passes a chain.
fixed on the shaft 43. The pressure rollers are mounted in any suitable manner on the plate '71 and extend through suitable openings therein for engagement with the blank 42 and the high speed rollers '79.
The blanks 42, cut one after another by the described means for this purpose, are delivered in livered in front of each form 40 across the opening '72 and onto supports or stops 86, 'just before the form passes through said opening. The supports or stops B6 are arranged at opposite sides of the opening '72 and said supports or stops are bolted or otherwise suitably secured onthe plate 71 near the bottom thereof.
As each form 40 moves through the opening '72 in plate '71, the blank 42 in front of said form is forced thereby through said opening and folded around the front and opposite sides of the form by rollers 87 extending vertically at opposite sidesof the opening '72 and journalled in any suitable manner on the plate '71 (Fig. 4). Brushes 88 between which the form passes, then engage opposite sides of, the blank and hold it against the form until folding mechanism, to be presently described, folds and seals the blank-on the back of the form. The brushes 88 are carried by holders 89 that are mounted in any suitable manner on the plate '71 (Fig. 6).
In accordance with the present invention, the waxed paper blank 42 is made into a liner or container on the form 40, by means including movable devices that both fold and heat seal said liner or container. As herein shown, the panels 90 of the containers A are folded around the forms 40 by cold folders 91, and the panels 92 of said containers are folded around said'forms by hot" folders 93, said folders moving continuously in closed paths in timed relation with the continuously moving forms 40, and the folders 93 actin to heat seal overlapping portions of the panels 90 and 92 so that each liner or container A is sealed along one side thereof through the medium of the wax with which the container formin The folders '91 are preferably operated, mounted, and constructed as follows.
r 1 Fixed on'the shaft 43 is-a sprocket 94 around. which passes a chain 95 engaged by anidler 96- which serves to maintain proper tension on said chain and is mounted on the machine framework in any suitable manner. The chain 95 also passes around a sprocket 6'7 which is fixed on a shaft 98 extending transversely of the machine between the ways 39 and journalled in suitable bearings on theside frames 5 and'6. The shaft 98 is thus driven continuously through the described driving connections therefor with the 'shaft'43. Fixed on the shaft 98 adjacent one end thereofis a bevel gear 99 which meshes with a similar gear 100 that is fixed on a verticalshaft 101 adjacent the lower end thereof (Figs. 4 and 6) The shaft 101 i's'journalled in, suitable bearings onthe side frame ,6. and fixed on saidshaft is a sprocket 102 around which passes a chain,103,engaged by an idler sprocket 103' mounted on the side frame Gin.
any suitable manner and serving tomaintain proper tensionbn said chain. The chain 103 also passes around-a sprocket 104 that is fixed on a shaft 105 extending vertically between ways 106' able means on upper and lower brackets 107 and 108 respectively which are bolted or otherwise suitably secured on the side frame 6 (Figs. 1, 2 and 4). I
Fixed on the shaft is a sprocket 109 around which passes a chain 110 that also passes around a sprocket 111. The sprocket 111 is fixed on a shaft 112 which extends vertically between the ways 106 and is journalled thereon in any suitable manner. The cold folders 91, herein shown as four in number, are secured to the chain 110 at intervals along the same, and said folders and said chain are driven continuously in a closed or endless path by the described driving connections for the chain with the continuously driven shaft 98. The folders 91 are identical as respects mounting, construction, and operation, and it is therefore only necessary to describe one of said folders. Each folder includes a vertical tubular boss 113 (Fig. 11) having secured thereto or formed integrally therewith spaced parallel plates 114 extending over the chain 110 and secured thereto as by pins 115 which pass throughcertain of the links of said chain. Journalled on the pins 115 and retained against displacement therefrom in any suitable manner, are rollers 116 which travel in suitable guides 117 formed on the ways 106 at the tops and bottoms thereof, respectively.
Journalled in the boss 113 is a'shaft 118 having arms 119 and 120 fixed on the upper and lower ends thereof, respectively. The arm 120 has journalled thereon in any suitable manner, a roller 121 which extends in the groove 122 of a cam 123 made in the form of an elongated plate of irregular configuration and secured in any suitable manner to the brackets 108 below, and 1 in spaced relation with, the ways 106. Pivoted at 123' on the arms 119 and 120, are folder arms 124 on corresponding ends of which are mounted the folder 91. As herein shown, the folder proper is comprised by a small vertically extending shaft 125 mounted on the folder arms 124 and carrying ribbed rollers or the like indicated at 126. Shaft 125 and the rollers 126 are retained against displacement from the folder arms 124 by any suitable means for this purpose, and said folder arms have pivotally connected therewith, as at 127, corresponding ends of links 128 the opposite ends of which have pin and slot connections 129 and 130, with arms 131 that are secured to or formed integrally with the boss 113. The arms 119 and 120 have secured thereto, as by clips 131', corresponding ends of springs 132 the opposite ends of which are secured, as by pins 132', on the links 128 adjacent the slots therein. During travel of the chain 110 and the folders 91, the latter are operated, through engagement of the roller 121 with the cam 122, to fold the panels 90 of the blanks 42 on the forms 40, as before pointed out. The links 128 and the springs 132 normally maintain the folders at right angles to the arms 119 and 120, but provide for yielding movement of .said folders to insure engagement of the same with the forms 40 and prevent damage to the folders.
The folders 93, as previously pointed out, fold the panels 92 of the blanks 42 on the forms 40, and said folders are preferably operated, mounted, and constructed as follows: Fixed on the continuously driven shaft 98 at the end opposite that carrying the bevel gear 99, is a bevel gear 133 which meshes with a similar gear 134 that is fixed on a vertical shaft 135 adjacent the lower end thereof (Figs; 2, 4 and 6). This shaft 135 is journalled in suit-,
able bearings on the side frame 5. and said shaft has fixed thereon a sprocket 136 around which passes a chain 137. An idler sprocket 138 engaging the chain 137 serves to maintain proper tension thereon, and said idler sprocket is journalled in any suitable manner on the side frame 5 of the machine. The chain 137 also passes around a sprocket 139 that is fixed on a vertical shaft 140 extending between ways 141 and journalled thereon in any suitable manner. The ways 141 are secured in any suitable manner to upper and lower brackets 142 and 143 respectively, which, in turn, are bolted or otherwise suitably secured to the side frame 5 of the machine (Figs. 1, 2 and 4).
Fixed on the shaft 140 is a sprocket 143 around which passes a chain 144 that also passes around a sprocket 145. This sprocket 145 is fixed on a shaft 146 which extends vertically between the ways 141 and is journalled thereon in any suitable manner. The folders 93, herein shown as three in number, are secured to the chain 144 at equal intervals along the same, and said folders and said chain are driven continuously in a closed or endless path through the described driving connections for the chain with the continuously drivenshaft 98. The folders 93, as respects their mounting, construction, and operation, are identical and it is therefore only necessary to describe one of the same.
Each folder 93 is carried by a vertically extending tubular boss 147 which has secured thereto, or formed integrally therewith, spaced plates 148 that are engaged over the chain 144 and secured thereto, as by pins 149 which extend through certain of the links of said chain (Figs. 12, 13 and 14). Journalled on the pins 149, and retained against displacement therefrom by any suitable means for this purpose, are rollers 150 which travel in suitable guides 151 on the ways 141. Rotatably mounted in the tubular boss 147 is a shaft 152 having fixed on the upper and lower ends thereof arms 153 and 154, respectively. The arm 154 has journalled thereon a roller 155 which extends in the groove 156 of a cam 157 comprised by an elongated plate of irregular configuration (Fig. 4). This cam 157 is secured in any suitable manner on the brackets 143 below the ways 141 and in spaced relation therewith.
Journalled in suitable openings in the arms 153 and 154 are pins 158 which project through said openings from opposite sides of said arms and have arms 159 and 160 that are rigidly secured on the pins 158 in alinement and turn therewith on the arms 153 and 154, respectively. The arms 160 have pivotally connected therewith corresponding ends of links 161 the opposite ends of which have pin and slot connections 162, 163 with arms 164 that are secured to or formed integrally with the boss 147. Secured. as by pins 164' to the links'161 adjacent the slots 163 therein, are corresponding ends of springs 165 the opposite ends of which are secured, as by clips 166, to the arms 153, 154, at the free ends thereof. The arms 160 have secured thereto in any suitable manner, arms 167 of a plate 168 on one edge of which is riveted or otherwise suitably secured the folder 93. The links 161 and the springs 165 normally maintain the folders 93 at 92 of the blanks 42, in overlapping relation on m,
the back of the forms 40, as previously described, and the folders '93 are, in accordancev with the present invention, heated so that said overlapping panels or portions are heat sealed through the mediumof the wax or substance with which the blank is coated or impregnated. Accordingly, the folders 93 are preferably heated electrically through the medium of heat elements ap plied thereto and travelling therewith, and the current for heating said elements may be supplied thereto from any suitable source. As herein shown, a generator 169 (Fig. 15) having a ground lead 170, is connected by a lead wire 171 with a contact 172 provided on a switch panel .173 made of suitable insulating material and mounted on the side frame 5 of the machine in any suitable manner. The switch panel 1'73 also has mounted thereon a switch 1'74 movable into engagement with the contact 172 and connected by a lead wire 175 with the resistance element 176 of a rheostat 1'77. This rheostat 177 is employed to vary the current in the heaters on folders 93, as desired, and includes an arm 1'7'7 movable along the' element 1'76 in engagement. therewith and connected by a lead wire 1'78 with an elliptical track 1'79 of copper or other suitable material mounted on'a plate 180 of 'similar configuration and insulated therefrom inany suitable manner .(Figs. 1, 2 and4).
The plate180 in turn, is mounted in any suitable manner on the brackets 142 above the ways 141, so that the track 179 is disposed in position for engagement by brushes 181 which are mounted on the folder-carrying bosses 147 and travel around said track in engagement therewith as the folders 93 are moved continuously along their closed or endless path by the described means for this purpose. The brushes 181 extend in suitable slots formed in fiber blocks 182 which, together with said brushes, are secured in any suitable manner on fiber supports 183 at'the upper ends thereof (FigsQl, 2, 4, 12 and 13). The lower ends of the supports 183 are secured in any suitable manner on arms 184 which, in turn, are secured to, or formed'integrally with, the bosses 147.
The brushes 181 have connected therewith, as at 185, lead wires 186 which are connected with lead wires 187. The lead wires 186 and 187, in
.turn, are connected at 188 with the arms 159 and areinsulated, therefrom in any suitable manner. The lead wires 187 are also connected,
as at 189, with corresponding ends of resistance elements 190 enclosed in heaters 192 and insulated therefrom in any suitablemanner. The
heaters 192 are secured" in any suitable manner lead wires 18'! are connected, as at 194, with lead 7 wires 195 which, in tum; are connected, as at 196, with the lowermost arms, 167 and thus grounded on the folder carrying means. It will appear, from the foregoing, that when the switch 174 is closed, current will be supplied to the refolders 93- during operation of the same by the described mechanism for this purpose.
The forms 40' and the folders 91 and'93 travel continuously in timed. relation that said with the back of the form '40. The folder'91 is .then moved outwardly a slight distance through of the roller 155 with a dwell 199 in the cam 15'7.
folders fold in and overlap portions of the blanks on the forms successively and heat seal the overlapping portions of said blanks in like manner. 1 Accordingly, as a form 40 with a blank wrapped around the front and opposite sides thereof moves between the cams 123 and 157, one of the folders 1 91 and one of the folders 93 act to fold in, overlap, and heat seal the blank on the back of the form, as stated. The folder 91 is first moved inwardly through motion imparted thereto by engagement of the roller 121 with a dwell 198 (Fig. 4) in the cam 123, so that said folder engages the panel or portion of the blank 42 and swings said panel or portion into engagement engagement of the roller 120 with a dwell 198' in the cam 123, whereupon the folder 93 is moved inwardly backof the form through engagement The folder 93 thus engages the portion or panel 92 of the blank 42, swings it inwardly of' the form in overlapping relation with the portion or panel 90, and heat seals the overlapping portions of the blank, whereupon the form 40 and the two folders 91 and 93 travel forwardly together,-the folders 91 and 93 engaging the blank or .liner and the form and being maintained in side by side relation against the back of the portions of the blank or liner thereon, through engagement of the roller 121 with a dwell 203 in-the cam 122. Thereaftenthe folder .91 is moved out of engagement with the form and the blank or liner thereon, through engagement of the roller 121 with a dwell 204 of the cam 122, whereupon the two folders are moved outwardly through engagement of the rollers 121 and 155 with the cam grooves 122 and 156 of the cams 122 and .157. The two folders 91 and 93 then move rearwardly and inwardly to fold in a blank 125 on a succeeding form, as in the case oi. the first described folding operation.
It will, of course, be understood that as each form passes between the cams 123 and 157, one of thefolders 91 and one of the folders 93 will 6 fold the blank thereon in the manner already described. The number of folders 91, as previously pointed out, is greater than the number of folders 93, and this is preferable for the reason that it is desirable to, holdan unheated folder 91 in engagement with the overlapping portions of the. blank or liner on the back of the form after a heated folder 93 has been disengaged therefrom, until a sufficient time has elapsed for the wax or other substance to set and thus no insure. a perfect seal. The arrangement, construction, operation, and timing of'the folders 91, 93 and the forms 40, however, are such that one folder 91 and one folder 93 always cooperate in the folding of a blank or liner on the back of each form 40in the manner previously described. Y Y
' The forms 40 and the blanks or liners successively pass top folding. mechanism which acts to fold'in and heat sealen'd portions of the blanks 150 or liners one after another as the forms and ing plate 205 is of irregular configuration and provided at opposite sides thereof with wings or extensions 209 and 210, respectively. This folding plate 205 has secured to or formed integrally therewith spaced pairs of lugs 211 in slots of which are received a holder 212 that is secured in any suitable manner to said lugs. The holder 212, in turn, is secured to or formed integrally with a cross member 213 which extends transversely of the machine and is supported on the side frames 5 and 6 therefor for movement relative thereto so that the folding plate 205 may yieldably engage the forms 40 and the blanks or liners thereon.
The folding plate 206 is mounted in any suitable manner on one of a pair of bars 216 and supported therefrom in spaced relation with the wing 210 of the folding plate 205. The folding plates 207 and 208 are hinged at 2141 and 215, respectively, on one of a plurality of cross bars 217 adjustably connected with the bars 216. The bars 217 extend transversely of the machine and are secured in any suitable manner to the side frames 5 and 6 thereof.
As each form 40 with a blank or liner 42 thereon passes under the folding plate 205, the front top portion 218 of said liner or blank is folded down on the top of the form by a curved folder 210 which is secured to or formed integrally with the folding plate 205. Thereafter, the rear top portion 220 of the blank or liner is folded down on the top of the form 40 by a swinging folder 221 comprised by a roller or rollers journalled in any suitable manner on an arm 222 that is fixed on a rockshaft 223. This rockshaft 223 extends transversely of the machine and is journalled in suitable bearings on the side frames 5 and 6 at the tops thereof. Fixed on the rockshaft 223 is an arm 224 which is pivotally connected with one end of a link 225. The opposite end of the link 225 is pivotally connected with one end of a lever 226 which is pivotally mounted at 227 on the side frame 6 of the machine. The opposite end of the lever 226 has journalled thereon a roller 228 engaged in a closed cam 229 which is fixed on the shaft 43 and shaped to rock the folder 220 each time a form passes thereunder so that said folder folds in the rear top portion of the blank or liner under the folder 219 and onto the top of the form. 40. A
While the forms 40 and the blanks or liners thereon pass the movable and stationary folding devices, said blanks or liners are maintained in engagement with opposite sides of the forms by brushes 230, 230, 231, 231', 232, 232 and 233, 233' extending horizontally adjacent the tops and bottoms of the forms 40 (Fig. 6). The brushes 230, 231, 232 and 233 are mounted on brackets 234 adjustably secured in any suitable manner on the bars 216, and the brushes 230", 231", 232' and 233 are mounted on brackets 234' adjustably secured in any suitable manner on the cams 123 and 157. The several brushes, together with the movable and stationary folding devices, insure that the blanks 42 will be tightly held against the forms while said blanks are being formed into bags or liners or containers thereon. When the front and rear portions 218 and 220 of the linerblank have been folded down on top of the form, as be fore described, the opposite side portions 235 and 236 of said blank are swung outwardly between folder wing 209 and brush 232 and folder wing 210 and folder 206, respectively. In the continued travel of the form 40, the liner flap 235 is engaged between the folder plate 207 and a wing 237 of plate 205 and folded down on top of the form above the liner flaps 218 and 220, whereupon the liner flap 236 is engaged between the folder plate 208 and the wing 237 and folded down on top of the previously folded liner flap 235. The closed end portions of the liners or containers are thus formed one after another by the described folding devices for this purpose, and as each form and liner travels forwardly of the folding plate 208, the closed end of the liner or container is engaged and sealed by rotatable heated rolls which are preferably operated, mounted, constructed, and heated, as follows. i
. Fixed on the shaft 98 is a sprocket 238 around which passes a chain 239 which also names over idler sprockets 240 and a sprocket 241 (Figs. 2 and 6). The idler sprockets 240 are journalled and mounted on the side frame 5 of the machine in any suitable manner and the sprocket 241 is fixed on a shaft 242 extending transversely of the ma-,
chine and journalled on the side frames 5 and 6 at the tops thereof. Fixed on the shaft 242 and driven thereby through the described driving connections therefor with the shaft 98, is a gear 243 which meshes with a gear 244 that is fixed on a shaft 245 driven through said gears from the shaft 242. The shaft 245 is journalled in suitable bearings on the arms 246 of a yoke 247 carried by arms 24B loosely mounted on the shaft 242. The yoke 24'? and the parts carried thereby, are yieldably supported from the bars 216 by a bolt 247' extending loosely through a suitable opening in one of a pair of small cross bars 247" bolted or otherwise suitably secured to bars 216. The bolt 247 has mounted thereon a spring 250 disposed between the yoke 247 and the bar 247" through which said bolt extends.
Fixed on the shaft 245 is a roller 251 driven by said shaft to rotate in engagement with the interfolded closed ends of the bags or containers on the forms 40 so as to heat seal said interfolded closed ends of said bags or containers. This driven heat sealing roller 251 is preferably heated electrically, and as herein shown, includes a plurality of heaters 252 which are arranged in suitable openings in said roller and have resistance elements 253 (Fig. 15) suitably insulated from the heaters and the roller and supplied with current as follows.
The contact 172 on the switch panel 173 is connected by a bus bar 254 with a contact 255 on said panel. Mounted on the panel 173 is a switch 256 which is adapted to be moved into engagement with the contact 255 and is connected with one end of a lead wire 257. The cpposite end of the lead wire 257 is connected with the resistance element 258 of a rheostat 259 by means of which the current in the resistance elements 253 of heaters 252 maybe varied as desired. This rheostat 259 includes an arm 260 which is movable over the'resistance 258 in engagement therewith, and connected with the arm 250 is one end of a lead'wire 261. The opposite end of the lead wire 261 is connected with short lead wires 262 and 263, the lead wire 262,
in turn, being c'onnectedwith a circular contact ring 264 loosely mounted on, and insulated from,
' element 253 of meet the heaters 252 and suit-v if desired, be provided to assist in heat sealing ably insulated from said roller to prevent grounding thereon. The resistance elements 253 of the several heaters 252 are connected in series, as by lead wires 266, the last heater of the series having its resistance element grounded on the roller 251. It will appear, from the foregoing, thatwhen the switch 256 is closed, current will be supplied to the resistance elements 2530f heaters 252 during rotation thereof withthe roller 251,
and said roller will'thus be heated and act to heat seal the closed ends of the liners or containers as the formscarrylng them pass under said roller. A second heated roller 268 (Figs. 2 and 4) may,
the closedends of the liners or containers, and saidroller may be positively driven, or may operate through frictional engagement thereof with the ends of the containers or liners and the forms 40. As herein shown, the roller 268 is frictionally operated, and said roller is preferably mounted, constructed, and heated as follows,
Loosely mounted on the shaft 242 and retained against endwise displacement thereon in any suitable manner, are arms 269 in the free ends of which are provided bearings for a shaft 2'70 on which the roller 268 is fixed. The shaft 270 passes through suitable openings in the arms 271 of a yoke 272. The yoke 272 .is supported from the bars 216 by a bolt 273 which passes through a suitable opening in said yoke and one of the bars 24'7" and carries a spring 274 disposed between the yoke and the bar 247' associated therewith. The roller 268 engages the tops of the forms 40 and the closed ends of the liners or her. "with one end of the lead wire 263 the opposite said heaters and the roller 268 and connected in' series. by lead wires 27'? (Figs. 6 and 15). Mounted on the roller 268 to rotate therewith, is a brush 2'77 insulated in any suitable manner from said roller and connected with one end of the first resistance element 276 of the series included in the heaters 2'75. One end of the last resistance element 2'76 of the series is grounded on the roller 268 and during rotation'of said roller, the brush 2'7'7 engages a contact ring 279 of copper or other suitable material loosely mounted on the shaft 2'70 and insulated therefrom in any suitable manner. The ring 279 is fixed on one arm 2'71 of the yoke 2'72 and insulated therefrom in any suitable man- This contact ring 2'79.has connected thereend of which is connected with the lead wire 261, as-previously described, so that when the switch 256 is moved into engagement with the contact 255 current will be supplied to the resistance ele ments 2'76 of heaters 275 on roller 288 as well as to the resistance elements 253 of heaters252 on roller 251. The two rollers thus act to press and.
heat seal the closed ends of the linersor con-' tions between the shafts 284 and the sprockets Whenthe liners or containers have been;

formed, as above described, they may be removed in any suitable manner from the forms 40, to be placed in receptacles or used in various other ways, or said liners or bags or containers may, before removal of the same from the forms 40, have formed thereon cartons or the like which are lined by the containers or bags or liners. In the latter case, it is desirable to secure the liners or bags to the carton in order to prevent material from sifting between the two when the lined receptacles are filled. As herein shown, the liners or bags are of waxed paper and, in accordance with the present invention, the carton or the liner or bag, will have applied thereto heated wax or;'
other wax-like substance similar to that with which the bag or liner is impregnated or coated, so that when the liner or bag and the carton or the like are assembled together, they will .be secured to. each other by said wax, and material will be prevented from sifting in between the carton and the bag or' liner when the receptacle is filled.
In the embodiment of the invention herein disclosed, heated wax is applied tothe liner or bag, whereupon a carton is formed on the bag or liner. andthe latter is secured to said carton by said wax, the :wax applying means being preferably operated, mounted, and constructed as follows.
Fixed on the shafts 101 and 135 at the upper ends thereof, are sprockets 280 around which pass chains 281 that also pass around idler sprockets 282 and driven sprockets 283 (Figs. 2, 4, 6 and 8).
The idler sprockets 282 serve to regulate the ten sion of chains 281, as desired, and said sprockets are journalled and adjustably mounted on bracke shafts between said collars and the'hubs ofthe sprockets 283. The shafts 284 are journalled in' any suitable manner on brackets 287 which are bolted or otherwise suitably secured on small brackets 288. The brackets 288, in turn, are
289 the latter, in turn, being bolted or otherwise suitably secured on the upper way 39 at opposite sides thereof, so that the forms 40 travel between brackets 287 and 289 and wax applying and holding means carried thereby, respectively.
Secured to or formed integrally with the sprockets 283, are bevel gears 290 which mesh with similar gears 291 fixed on shafts 292 inclined inwardly and downwardly toward each otherand journalled in suitable bearings on the brackets 287. The shafts 292 also have fixed thereon wax applying disks or wheels 293 which are inclined upwardly and inwardly toward each other and have beveled annular wax applying surfaces 294. These inclined wax applying wheels 293 extend within wax containing receptacles 295 which are bolted or otherwise sultably secured on the brackets 289, and said wheels are driven through the described .driving connections therefor with the continously driven shafts 101 and 135. If, for any reason, the machine is started when wax in the receptacles 295 is con- .gealed or not sufficiently melted, said wax would 120. bolted or otherwise suitably secured onbrackets wheels and driving means therefor, the connec- 110 ets 283' which are secured in any suitable mansaid shafts, thus afiording slippage between the bevel gears 290 and 291. When the wax in the receptacles 295 is melted, the springs 286 act to engage the bevel gears 290 with the bevel gears 291 so that the wax applying wheels 293 are rotated, as above described. Accordingly, dur ing the normal operation of the machine, the forms 40 with liners or contalners thereon pass one after another between the'rotating wax applying wheels 293 and the latter apply stripes of heated wax on opposite sides of the liners or containers. In order to insure against sticking of the liners or containers to the forms 20, when the liners or containers are sealed thereon and the stripes of wax are applied to opposite sides of the limbs or containers, said forms are provided on the front, top, and rear sides thereof with corrugations 296 and on the sides with wood strips 297 or the like against which the wheels 293 bear when applying stripes of heated wax to opposite sides of the liner. These strips 297 are secured in any suitable manner in grooves formed in opposite sides of the forms 40, respectively.
The wax in the receptacles 295 is, in accordance with the present invention, heated to maintain the same in a melted condition for application by the wheels 293 to the liners or containers, and said wax is preferably heated electrically in the following manner. The contact 255 on the switch panel 173 has connected therewith a bus bar 298 which is also connected with a contact 299 on said panel (Fig. 15). The panel 173 has mounted thereon a switch 300 movable into engagement with the, contact 299 and connected with'one end of a lead wire 391. The lead wire 301 has branches 302 connected with corresponding ends of resistance elements 303 forming parts of heaters 304 secured in any suitable manner on the bottoms of the wax receptacles 295 and serving to heat the wax therein. The resistance elements 303 are insulated in any suitable manner from the heaters 30% and the re= ceptacles 295. The opposite ends of the re= sistance elements 303 are grounded in any suit able manner on the receptacles 295, and when the switch 300 is closed, current will be supplied to the resistance elements 303 by the describedmeans for this purpose, and the heaters 304 will heat'the receptacles 295 and the wax therein.
Additional heaters are preferably employed on the sides cfthe wax receptacles 295, these additional heaters preferably being of the same type as the heaters 304 and supplied with electrical current as follows; The contact 299 on the switch panel 173 has connected therewith a bus bar 306 which is also connected with a con tact 307011 said switch panel. The switch panel 173 has mounted thereon a switch 303 movable into engagement with the contact 307 and con nected with one end of a lead wire 309. This lead wire 309 has branches 399' connected with corresponding ends of resistance elements 312 forming parts of heaters 311 secured in any suitable manner on opposite sides of the receptacles 295. The resistance elements 310 are insulated in any suitable manner from the heaters 311. and the receptacles 295, and the opposite ends or said v through the described means for this purpose.
The heaters 311 will thus heat the receptacles 295 and melt the wax therein, the provision of heaters on the sides, as well as the bottoms of the receptacles 295 enabling the wax to be melted quickly when the machine is started. After the wax in the receptacles has been melted, the bottom heaters 304 or the side heaters 311 may be thrown out of operation, so that one or the other serves to keep the wax in the receptacles 295 in melted condition. All of the heaters may, however, be employed, if desired, in accordance with the particular conditions of operation of the machine and the particular nature of the wax employed.
After the closed ends of the liners or containers are heat sealed, the forms and the liners or containers thereon pass one after another under a cooling plate 312 (Figs. 2, 4 and 6) which cools the sealed ends of said liners or containers. This plate 312 is provided therein with air vents or openings 312 and isyieldably supported, as by a bolt 311.2 and a spring 312, on an extension 312 of one of the cross members 217. The bolt 312 is threaded in a suitable opening in the plate 312 and extends upwardly through a suitable opening in the extension 312 The spring 312 is mounted on the bolt between the extension 312 and a collar 312 on said bolt. The bolt is provided above the extension 312 with a nut 312 and the plate 312 has secured to, or formed integrally'therewith, a curved end 3i2 under which the forms 40 and the liners thereon pass in engagement with said plate. The forms 90 and the liners thereon pass one after another to mechanism for forming cartons thereon as follows.
The cartons B (Fig. 10) are made from blanks 313 which are fed into the path of travel oi the forms 30 one after another and formed into containers thereon by mechanism which is preferably operated, mounted, and constructed as disclosed in Patent No. 1,674,921 granted June 26, 1923, to G. A. Robinson, and in my co-pending application Serial No. 413,349, filed January 3, 1930. Accordingly, the shaft 30 has fixed thereon a sprocket 314 around which passes a chain 33.5 which also passes around a sprocket 313 which is fixed. on a shaft 317 extending transversely of, and journalled in suitable hearings on spaced frames 313 and 319 (Figs. 3 and 5). The frames 313 and 319 are bolted or otherwise suitably secured on frame members 320 and 321 supported at their ends by standards 322 which, in turn, are bolted or otherwise suitably secured to the machine foundation 9.
The frame members 320, 321 extend forwardly over the liner and carton making machine and are supported thereon by cross members 323 extending transversely of said frame members and bolted or otherwise suitably secured thereto (Figs. 2 and 3). The cross members 323, in turn, extend transversely of, and are bolted or otherwise suitably secured to, frames 32% and 325 mounted on the side frame members 5 and 3 and bolted or otherwise suitably secured thereto in any suitable manner. Mounted on the frames 313 and 319, the standards 322, and base plates 326 for the latter, is an elevator including endless driven chains 327 operated from the shaft 317, as disclosed in application Serial No. 418,349 above referred to, and supporting a stack 328 of carton blanks 31.3 which are separated one after another from the top of the stack and fed forwardly in like-manner by a separator roller 329. This roller 329 is supported in engagement -with the .top of-the stack by a weighted yoke joumalled on theshait an, and said roller is driven from said shaft by'suitable gearing for.
are mounted and operated as disclosed in Patent.
l the glue wheel shaft 346 and mounted in any this purpose. Journalled on the frame319, is a short vertical shaft 330 which is driven in any suitable manner from the shaft 317 and carries a bevel gear 331 which meshes with a similar gear 332. The gear 332 is fixed on a horizontally arranged cam shaft 333 extending longitudinally of'the-frame member 21 and journalled in suitable bearings thereon. The elevator 327, the separator roller 329, and the cam shaft 333 are thus operated by the connections therefor with the shaft 30.
The blanks 313, separated andforwarded successively from the top of the stack by the roller. 329, are delivered thereby one after another be-.
tween upper and lower feed tapes 334 and 335 respectively that pass around suitable rollers which are arranged at opposite ends of said tapes and journalled in suitable hearings on brackets bolted or otherwise suitably secured to the frame bender 337 and a side registering device 338 for registering the blanks therewith. This fiap bender 337 and the side registering device 338 335to the grippers 340 of a turning roll 341 comprised by wheels on disks fixed on a shaft 342 extending transversely of the frame members 320, 321 and journalled in suitable bearings thereon (Figs. 2 and 5). The turning roll 341 and the grippers 340 thereon, are operated by the mechanism for this purpose disclosed in Patent No. 1,674,921 and including a bevel gear 343 fixed on the shaft 342 at one end thereof and mesh ing with a'similar gear 344 fixed on the driven cam shaft 333. Each blank 313 seized by the grippers 340 of turning roll 341 is turned thereby from a substantially horizontal position to a substantially vertical position and fed downwardly into the path of travel of one of the forms 40. During downward travel of the blanks, the flap 339 of each blank has applied thereto adhesive, through the medium of glue mechanism which is mounted, constructed, and operated as disclosed in Patent No. 1,674,921. This glue mechanism includes a glue wheel 345 fixed on a shaft 346 and tuming in glue contained in a box 347 supported by a bracket 347' on the frame 6 of the machine (Figs. 2 and 4). The shaft. 346 is journalled in suitable hearings on the glue box bracket 347, and said shaft has fixed thereon a sprocket 3413 around which passes a chain 349. The chain 349 also passes around a sprocket 350 fixed on the continuously rotating cam shaft 333, and it will thus appear that the glue wheel 345 is driven by thedescribed driving connections therefor with said cam shaft. The glue wheel 345 applies glue to theperiphery of" a roller 351 driven by suitable gearing from suitable manner on the glue box bracket 34?. A second roller 352 mounted in any suitable man- -the blank is folded around the front and opponer on the glue box bracket 347', is moved towardand away from the roller 351 by suitable mechanism for this purpose operated from the cam shaft 333, as disclosed in Patent No. 1,674,921. As the blanks 313 are fed downwardly from the turning roll 341, they pass between a guide plate 353 and guide bars 353' disposed vertically in spaced relation and supported in any suitable manner on the side frames 5 and 6 of the machine. As each blank 313 passes through the guides 353, 353', the bent flap 339 passes between the rollers 351 and 352, and adhesive is applied to said flap.
- The blanks 313 are fed downwardly between the guide plate 353 and the guide bars 353', by g rollers 354 and 355 extending therein. The rollers 354 are fixed on a shaft 354 journalled in suitable bearings on the guide plate 353 and extending transversely thereof. The shaft 354' and the rollers 354 thereon are driven from the shaft 342 by means of a sprocket 356 fixed on the shaft 354', a chain 35'? passing around said sprocket, and a sprocket 358 fixed on the shaft 342 and around which the chain 357 also passes. The rollers 355 are fixed on a shaft 359 jour- .nalled in arms 360 pivoted on the guide plate 353 and said shaft and said rollers are driven through suitable gearing from the shaft 354'. v
The plate 353 is provided in the bottom portion thereof with an opening 362 through which the forms '40 and the liners or containersthereon travel one after another. As the blanks 313 are fed by the rollers 354, 355 one after another between the guide bars 353' and the plate 353,
they are seized by feed rollers 363 and 364 which 116 feed each blank downwardly onto stops 365 mounted in any suitable manner on the plates 361 at opposite sides of the openers 362 therebetween. The feed rollers 363 extend through suitable openings in the plate 353 and are driven from the shaft 354' which, for this purpose, has fixed thereon a sprocket 366. Passing around the sprocket 366 is a chain 367 which also passes around a sprocket 368 that is fixed on a shaft 369. The rollers 363 are also fixed on the shaft 120 369, and said shaft extends transversely of the machine and is journalled in suitable hearings on the side frames'5 and 6 thereof. The rollers 364 are driven from the shaft 369 by suitable gearing for this purpose, and said rollers are fixed on a shaft 370 extending transversely of the machine and jo'urnalled in suitable bearings on arms 361 mounted in any suitable manner on the plate 353. v s
As each carton blank 313 with the side flaps engages the same and forces the blank between rollers 371 between which the forms 40 travel.
These rollers 3'71 are journalled in any suitable manner on the plates 353, and as a form with a liner or container thereon in a carton blank in front of the same passes through said rollers,

after another past said folder.
The folder 373 is operated, mounted, and constructed in substantially the same manner as the rear panel folder disclosed in Patent No.
1,674,921. Accordingly, the shaft 34 has fixed thereon a sprocket 374 around which passes a chain 375 that also passes around a sprocket 376 fixed on a shaft 377 extending transversely of the machine and journalled in suitable hearings on the side frames. 5 and 6 thereof (Figs. 2 and 3). Fixed on the shaft 377 is a sprocket 378 around which passes a chain 379 that also passes around a sprocket 380 fixed on a shaft 381 extending transversely of the machine and journalled in suitable bearings on the side frames 5 and 6 thereof. The shaft 381 is thus driven continuously through the described driving connections therefor with the shaft 34, and said shaft 381 constitutes the main driving shaft for devices that impart the described travelling and folding motions to the folder 373.
The forward and rearward movement of the folder 373 is derived from the shaft 381 through a bevel gear 382 which is fixed on said shaft and meshes with a similar gear 383. The bevel gear 383, in turn, is fixed on a shaft 384 at the lower end thereof, said shaft being journalled in suitable bearings on the side frame 5 of the machine. Fixed on the upper end of the shaft 384 is. a sprocket 385 around which passes a chain 386 that also passes around a sprocket 387 fixed'on a, short vertical shaft 388 at the lower end thereof. This shaft 388 is journalled in a suitable hearing on a box-shaped bracket 389 which is bolted or otherwise suitably secured to the side frame (Figs. 2 and 5). Fixed on the upper end of the shaft 388 is a sprocket 390 around which passes a chain391 that also passes around a sprocket 392 fixed on the upper end 'of a short verticalshaft 393.

The free end of the arm 402 has connected therewith, as by a universal connection, one end of a link 404 the opposite end of which is likewiseconnected with one arm 405 of a bell crank 406. This bell crank 406 is flxedon a rockshaft 407' extending in parallel relation with the guide rod 398 and 'joumalled in suitable bearings onthe bracket 389. One end of the rockshaft 407 has fixed thereon an arm 408 with which is connected oneend of a rod 409 the opposite end ofv which is connected with the other arm 410 of the bell crank 406. The rod 409 extends between rollers 411 journalled in spaced relation on a slide 412 extending diagonally across the carriage 397 and guided thereon in any suitable manner. The folder 373 is pivotally mounted at 413 on one end of the slide 412, and said folder receives its inward and outward movement as said slide is reciprocated through the described connections therefor with the shaft 381.
The folder 373 is also swung, at proper intervals, to swing in and seal the panel 372 of the carton, and for this purpose, the folder has connected therewith one end of an arm 414 the opposite end of which is pivotally connected with one end of a link 415. The opposite end of the link 415 is pivotally connected with the guide for the slide 412. The forms 40 and the folder373 are operated in such timed relation, that as each form approaches the folder, the latter moves inwardly on the back of the form to engage the panel 372 of the carton on the outer rear corner of the form and thus crease the corresponding corner of the carton thereon. The folder is then swung, by the arm 414 and the link 415, moving the panel 372 onto the form over the glued'sealing flap 339 of the carton and sealing said panel thereon. The folder then travels forwardly with the form pressing the overlapping panel and flap to secure them together, whereupon the folder is swung away from the form and then moved outwardly and rearwardly for subsequent movement to fold in the rear panel of the carton'on the next form 40, in the same manner. 'It will thus appear, that the folder 373 acts to side-seal This cam 399 has engaged in the cam I the cartons on the form successively as the latter travel in like manner past said folder.
After each carton is side-sealed on the form and secured to the liner, as previously described, one end of the carton is closed and sealed over the closed and sealed end of. the liner or container. Accordingly, the end flap 416 of the car ton is folded down on top of the liner and form by a stationary folder 417 (Fig. 2) under which the forms travel one after another. This folder 417 is supported in any suitable-manner, as by a cross member extending transversely of the machine and secured to the side frames 5 and 6 at the tops thereof. The opposite end flaps 418 of the carton is folded down on top of the form and the liner or container by a'movable folder 419 carried by an arm 419' fixed on a rockshaft 420 extending transversely of the machine and journalled in suitable hearings on the side frames 5 and 6 of the machine. fixed thereon an arm 421 with which is pivotally connected one end of a link 422. The opposite end of the link 422 is pivotally connected with an arm 423. This arm 423 is pivotally mounted at 424 on the side frame 6 of the machine and This rockshaft 420 has carries a roller 425 which is engaged in the groove of a closed cam 426. The cam 426 is fixed on the shaft 34 at the end, thereof opposite that carrying the sprocket 33, and said cam is so shaped that as. each carton passes under the folder 419,
the same is moved to fold down the flap 418,
through the described connection for said folder with the cam 426.
As the carton flaps 416 and 418 are folded by the described means for this purpose, and the form with the carton thereon moves forwardly, said flaps are held down by a suitable guide rail for thispurpose and the side flaps 427 and-428 of the cartonare bent outwardly by the folder 417 and engaged under guide rails 417 supported on the machine frame work in any suitable manner. The flaps 427, 428 are thereafter engaged by glue wheels 429 which apply glue to said flaps. and said glue wheels are fixed on a shaft 430 and extend within boxes 431 containing glue or other adhesive. The glue boxes 431 are mountand 6 of the machine,-and the'shaft 430 extends transversely: of, and is journalled in suitable bearings, on said glue boxes. The shaft 430 and i the glue wheels 429 thereon are preferably driven from the shaft 20 which, for this purpose, has fixed thereon .a pinion 432 which meshes with a gear 433 that is fixed on the shaft 430.
It will appear, from the foregoing, that glue is applied to the flaps 427, 428 of the cartons as the forms and cartons thereon travel one after another past the described means for this purpose. The forms and cartons, after passing the glue wheels 429, turn downwardly and travel in the opposite direction past stationary folders 434 and 435, the folder 434 serving to fold in and seal the flap 427 on the flaps 416 and 418, and the folder 435 serving to fold in and seal the flap 428 on the flap 427 (Fig. 3). Thereafter, the
forms and the cartons thereon travel over a press.
mechanism indicated broadly at 436 (Figs. 2 and 3) which acts to press the sealed ends of the cartons prior to delivery of the same-from the 45 forms'in a manner to-be presently described. This press mechanism 436 may be of any suitable or well known construction, and is supported in any suitable manner on the side frames 5 and 6 of the machine between the same, and at the bottoms thereof. The movable parts of the press mechanism are driven by a belt 436' from the shaft 377.
It will appear, from the foregoing, that as the forms and cartons'thereon travel one after another past the folders 434, 435 and over the press mechanism 436, the flaps 427 and 428 of successive cartons 'will, be closed and sealed, as described, whereupon the cartons maybe moved one after another from the successive forms 40. Removal of the lined cartons from the forms may be accomplished byblasts of air delivered thereto, or by mechanical means,.as desired. In the embodiment of the invention herein shown, the lined cartons are removed from the forms 40 by inclined guide rails 437 (Figs. 1 and 2) extending from one end .of the press mech- Y anism 436 to one end of the machine proper and arranged to engage the open ends of the lined cartons successively to strip them one after anotherfrom the successive forms 40. The 'in-' 440 finally strip the cartons from the forms 40 for delivery onto a carton transporting means 441 or to any other suitable point of delivery. The carton transporting means 441 is driven by a chain 442 from the shaft 98. and the guides 439 and 440. are secured in any suitable manner on the ways 39 and the brackets 37, respectively.
The operation of the entire 'machine will be readily understood from the foregoing, and may be briefly summarized as follows. A waxed liner 42 cut from the web and delivered onto the stops 86 by the described means for this purpose, is engaged by one of the forms 40 which travels through the rollers 87 and folds the liner around the form. In continued, travel of the form, one
of the folders 91 and one of the folders 93 fold in the rear panels or portions 90 and 92 of the'liner and heat seal the overlapping parts of said panels orportions. As the form 40 with the side-sealed liner thereon passes the folders 219 and 221 the latter fold in the front and rear end portions 218 and 220 of the liner, whereupon the form and the liner pass the devices 207, 237, 208 which fold in the side portions 235 and 236 of the liner.
In the continued movement of the form 40 and the side-sealed liner or container thereon, the same pass the wax applying wheels 293 which apply stripes of hot wax to opposite sides of said container or liner, respectively. In the meantime, the form 40 with the side-sealed and endclosed liner or blank thereon passes under the rollers 251 and 263 which heat seal the closed end of the liner or container, wherepon the form with liner and secured thereto by the stripes of wax applied on the latter. Thereafter, the form with V the liner and carton thereon passes the folder 373 which folds in and seals the panel 372 of the carton on the flap 339 thereof. The form 40 with the side-sealed and lined carton thereon then passes the several devices for'end closing and sealing the carton, whereupon the form and the carton, pass over the press mechanism 436 and the carton is thereafter stripped from the form by the'described means for this purpose. The forms 40 travel continuously one after another past the various liner and cartonforming devices and have linedcartons formed thereon one after another in the manner above pointed out. 1
In the embodiment. of the invention herein disclosed, the liner forming mechanism and the carton forming mechanism cooperate in the making of lined cartons one after another.. The liner forming mechanism may, however, be separate from the carton forming mechanism, and may be employed to make. bags or containers used for lining cartons, or for various other purposes, as desired.
