Description
3~
The invention deals with a process for insertion of two rows of objects, for instance bottles, cans and the like, into a package which comprises a bl~nk of foldable material with ~ top wall, side wal~ adjacent the top wall on both side~ thereof and bottom halves connected to the side walls as well as edge tabs wllich by folding upwards, fo~m a longitudinal stifferler.
~' The invention is related to a special type of packaging . madQ of cardboa~d, corrugated cardboard or the li~e. The bottom halves receivs one ro~ of the objects each, and the longitudinal , : 10 sti~fener located bet~een the two rows for~s two halves of the 3 package, each of them accomm~datin~ one row of objects. In addi-tion to the double-walled longitudinal ~tiffener formed by the two edge tabs, one can provida cross-stiffeners, which enter be-tween the objects arranged longitudinally within the package.
::' These cross-stiffeners can form a part o~ the longitudinal stif~.
.~ . i fener as swivel tabs, or they can be fitted onto the longitudinal stif~ener as downwardly slit blanks. :~
.. ~ The purpose of the ~nvention is to provide a process to enable mechanized manufacture, filling and closure of packages, as described above, of objects being conv~yed on a continuous . basis.
The subject process solves the task by placing the package blank onto the rows of objects supported from the bo~tom .~ in an inclined position, wrapping the side walls and the bottom halves-around each row of objects, and folding the edge tabs in between the rows of the objects, whereupon the rows are straight-ened up and the edge tabs are pressed against each other and glued :, together.
he folding and filling procedure, described above, is ~ -~'' ~. ....
3~j continuous, which means that it occurs during uninterruped con-veying of the objects and packages. Each hal~ of the package, f constituted in the lower part by the bottom halves and connecting edge tabs of the longitudinal stiffener, is folded around a spread row of objects diverging towards the bottom. Thereafter, ., ; these ~illed package halves afe moved ~ogether until the edge tabs con~act each other, forming in this manner a rectangular-~,:
shaped packag~. The folding and filling procedur~ described above, i.e. the folding of the bottom halves and edge tabs around each of the rows of objects and the simultaneous folding of the side walls from an almost horizontal to ~he final vertical posi-tion, is based on the spreading movement of the rows of objects.
These rows of objects move during the transport from their origi-.,, ` ~ nally vertical and slightly divergent position to an increasingly ,: .
inclined position until at a certain point the spread rows ofobjects each contact the corresponding side wall and rest on one of the bottom halves~ From then on the package and the ~wo rows o objects are conveyed as a whole.
The folding and filling procedure described above makes it possible to ~ize the packa~e so that its inside dimensions are slightly smaller than the outside dimensions of the objects~
However, due to the spread position of the object~ and the down- :
ward divergence of the package halves, the objects can be inserted !- without the use o force~ The undersizing of the package will show only when the two package halves come together in the lower .,:',. :

for instance, by glueing. The end tabs ~18 and 19), in turn, overlap on the outside and in the lowe.r part of the package by a closing tab (22) attached to the top wall (10).
Fig. 1 shows a blank for a package of the above described design. The boundaries of the blank which form individual walls etc , are de~ined by prepunched bend lines (23), ~hown in this ~` case as chain~dotted~
~ The illustrated embodiment of the packages is provided, ; . in addition ~o the longitudinal stiffenex (17), with cross stiffen-ers. In this case, these are formed as straps (24 and 25) pre-punched in the edge tabs (15 and 16~. The straps (24 and 25) are connected with the rest of the edge tabs (lS and 16) by bridges ~ (26). Each of ~he straps ~24 and 25), in turn, is flipped around ; : one of the bend lines in the bridge area into a position perpen~
~., ~,: dicular to the edge tabs ~L5 and 16) to form a cross-stiffener.
For this reason~ one ~alf of each of the straps (24 and 25) is ;
located on each side of the edge ta~s (15 and 16) and hence o . , . ; . .
~ the longitudinal stiffener ( 17) which is formed. Each of the .~.
halves of the straps ~24 and 25) projecting into the adjacent .,!~ 20 half of the package is inserted through the slot (27 and 28) of ~: the adjacent edge tabs (15 and 16). This makes it possible to form compartments by mea~ of the tw~ straps (24 and 25) to :
accommodate six objects, i.e. two rows with three objects each.
't.'': A package prepared in the above-mentioned manner is folded and filled with objects, for example bottles (29~ as -~ shown in Fig. 4. The blank shown in Fig. 4 differs from th~
~: one in Fig. 1 in that each of the end tabs (15 and 16) is providad with ~wo straps instead of one strap. ~--~ The flat blank is first partly folded. For this purpose, ~ ~ ~ j ~.' l~S~3~
the bottom halve~ (13;and 14) wi.th connecting edge tabs (15 and 16) are brought into an upri~ht position with re.spect to the hor-izontal side wa11s ~11 and 12) with the top wall in between (10).
The end tabs (18 and 19) and the corner tabs (20 and 2l) are straightened up in a similar manner. The latter are brought to the inside of the straightened end tabs (18 and 19) and joined with them, for example, by~ glueing. In this manner an inter-. mediate shape of the package is formed moving on the upper con-........... veyor (30) as shown in Fig. 4.
The objects, i.e. bottles (29), are conveyed under the upper conveyor (30) on a lower conveyor (31) in two adjacent rows.
From these endless rows, groups (32) are formed in the two rows, . each group consisting of row 33 and 34. The prefolded packages conveyed on conveyor (31).are turned through 180~ and placad on top of the bottles (29) with the bottom halves (13,14) and end tabs (15,16) directed downwards, so that the top wall (10) is ....
located in the area of the bottle caps.
From now on the groups~32 and the appropriate package travel together. During this movement the rows (33,34) are being spread gradually so that they diverge towards the bottom o the bottles. At the same time, the side walls (11 and 12) are folded in opposite directions, f~om the horizontal position into an ;t inclîned and finally vertical position. At some point alon~ the conveyor (31), ~he rows (33 and 34) are mutually moved into their .l respective package halves, touching the side walls (11 and 12) ~5' and resting on the bottom halves (13,14). In this manner, the . rows (33,34) in a spread position, are introduced into the un-.$ finished packageO

the rows of bottles are moved -to~ether at the bot~om. Prior to this, the edge tabs ~15 and 16) are folded upwards between the spread rows (33 and 34) and are moved clo~er toge~her during the approach of the package halves. Finally, the closing tabs t22) protruding in the area of the top wall (lQ~ are folded against the front walls of the package, i.e. against the end tabs (18 and 19).
The apparatus for this folding and ~illing procedure is construc~ed in a conventional manner. Figure3 5 - 13 show im-~; ~
portant details of the conveyor (31).
The approaching b9ttles (29) are conveyed in two rows (33 and 34) on support rails (35 and 36). The support rails (35 ~. , and 36) are shown in this case in the form of angle member~. Thebottles (29) rest on the lower legs (37) and lean against the ~; inward turned inside legs (38) which are dispo~ed with a prede-termined spacing therebetween. Between the two anglec~,members ~ ;
moves a bottle conveyor, in this case an endless chain conveyor .'~ ' ,:
,~ (39) with attachments (40~ for each of the groups (32).
During further transport of the rows (33 and 34) with the partly ~o~ded packages on top, the bottles and packages are held in the required relative position~ by guides of various ]ength and shape. These are mainly guide rods arranged in the direction of the tran~port.

initial area. The rows (33 and 34), already slightly diverging ! ~ at t~e bottom, are held on the support rails ~35 and 36~ by guide ; rods (41~ arranged on the out~ide. In the upper area of the side walls (11 and 12) are lo~ated the ends of the folding mechanism, i.e. two-armed folding levers (42 and 43). These and the , :

corresponding packa~e are :fuxther rotated by the folding levers ~42 and ar3) travelling over a certain distance of the tracX while applying the support rollers (44) to a curved rod (45). Due to the ~wivelling movement of the folding levers (42 and 43) ~hown in Figs. 5, 6 and 7, the ~ide walls (11 and 12) and the connected blank parts are :~olded downward toward~ the bottles (29)o The folding levers (42 and 43) are a~rried over a certain distance of the track by a conveying device not shown in detail.
~` The cross-section in Fig. 6 shows the side walls (11 and 1~) are already folded in this way into an inclined po~ition~
The bottles (29) are ~till in a position as shown in Fig. 5.
, In the cross-~ection shown in Fig. 7, the folding levers (42 and 43) have been moved out o t7ne package area. At the same time, outside rods (46) contact the side walls tll and ?. 12). These out~ide rods (46) converge in the dir~c~ion of trans-port. In addition, ~here are lower rods (47) provided at the underside of the package in the area of the bottom halves ~13 and 14), which support the package from below since with increas- :
~: in~ spreading of the rows (33 and 34j the top wall (10) no longer rests immediately on the bottle caps. The support rails (35 and ;; 36) originally ormed of angle merr~bers, gradually change into ~: relatively narrow flat ~hapes (48)~ These support the bottom ~; edges of the bottles (29) which are moved to the out~ide in a spreading movement. To bring about the vigorous spreading move-ment, two spxeader rods (49 and 50) are provided between th~
~-. rows (33 and 34) one on top of each other. At the start of the ... .
s~ ~preader track the aforementioned spreader rods t49 and 50) are connected with each other by their tips (see Fig. 13)~ The spreader rods (49 and 50) gradually diverge in the direction of ,,~ . ~.

Th~ final position of the spreading movement is ~hown in Fig. 8. The bottles are moved into ~he package halve~ until they touch the side walls (11 and 12~ and the bottom halves (13 and 14)o In this area new guide rods are added~ i.e. one support-ing rod (51) under each of the edge tabs (15 and 16). During ~urther mov~menk these support rods cause the inward swivelling of the edge tabs (15 and 16) in between the spread bot~les (29) (Figs~ 9 and 10)~ During this continuous folding procedure the lower spreader rod (50) from t.ime to time travel~ towards tha ~, .
Ij bottom area of the bottles (29) to ~ecure a perfect folding of .::
the edge tab~ (15 and 16) relative to the bottom halves (13 and ~ 14). ~oward the end of the conveyor (31) all of the rods between .; the rows (33 and 34)terminate. The package halves are now moved :: 20 together by outside support devices, for instance by the out~ide rods (46), and eventually aLso hy an additional campressing de- ;
vice until the opened edge tabs tl5 and 16) contact one another~
Prior to this, a glue nozzle (52) may be attached onto the con-~ veyor (31), applying glue to the areas of the edge tabs (19 and : 16) to be joined together.
~hen the package has the cxoss-~tiffeners formed by : the straps (24 and 25), these straps (24 and 25) are folded perpendicular to the edg~ ~abs (15 and 16), preferably in the ma~imum spread position (see Fig. 8), by a suitable device not : , :; ~
shown in deta.il. E'or this purpose support rods (51) are provided on the outside of the straps (24 and 25).
Following further folding movsment, i~e. the folding of the edge tabs t15 and 161 and the following approac~ of the pack-age halves in their lower parts, the halves o:f the straps (24 and 25) are inserted between the bottles (29), which are separated in the above manner I which is done partly by passing through the corresponding s lots (27 and 28).

. ~5 '' transport~ thereby effec~ing the gradual spreading of the adja-cent bottles (29)~ In this area also the support rails ~35 and 36), with the bottles inclined, are moved apart and at the same time change thei.r ~hape from angle men~bers into the flat shape (48).
Th~ final position of the spreading movement is ~hown in Fig. 8. The bottles are moved into ~he package halve~ until they touch the side walls (11 and 12~ and the bottom halves (13 and 14)o In this area new guide rods are added~ i.e. one support-ing rod (51) under each of the edge tabs (15 and 16). During ~urther mov~menk these support rods cause the inward swivelling of the edge tabs (15 and 16) in between the spread bot~les (29) (Figs~ 9 and 10)~ During this continuous folding procedure the lower spreader rod (50) from t.ime to time travel~ towards tha ~, .

Prior to this, a glue nozzle (52) may be attached onto the con-~ veyor (31), applying glue to the areas of the edge tabs (19 and : 16) to be joined together.
~hen the package has the cxoss-~tiffeners formed by : the straps (24 and 25), these straps (24 and 25) are folded perpendicular to the edg~ ~abs (15 and 16), preferably in the ma~imum spread position (see Fig. 8), by a suitable device not : , :; ~
shown in deta.il. E'or this purpose support rods (51) are provided on the outside of the straps (24 and 25).
Following further folding movsment, i~e. the folding of the edge tabs t15 and 161 and the following approac~ of the pack-age halves in their lower parts, the halves o:f the straps (24 and 25) are inserted between the bottles (29), which are separated in the above manner I which is done partly by passing through the corresponding s lots (27 and 28).

Claims (9)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. Process for insertion of two rows of objects, for example, bottles, cans and the like, into a package which comprises a blank of foldable material. having a one-piece continuous top wall, side walls adjacent the top wall on both sides thereof and hingedly connected thereto, and bottom halves connected to the side walls and comprising upwardly folded edge tabs which form a central longitudinal stiffener between the rows of objects, the process comprising the steps of folding the bottom halves and the adjacent edge tabs into a position perpendicular to the horizontal side walls and the top wall, and placing the partly folded package from above onto two rows of the objects which are in inclined position with their bottoms spread apart, wrapping the side walls and the bottom halves around each row of the objects, lifting the edge tabs and folding the edge tabs between the rows of the objects, and pressing and glueing the edge tabs together.
2. Process according to claim 1, wherein the steps of the process are performed as the rows of objects and the partly folded package are conveyed along conveyor means.
3. Process according to claim 2, wherein the partly folded package is moved towards the objects after the package is turned through 180°.
4. Process according to claim 1, wherein end tabs connected in the package end areas to the side walls by the bottom halves and the edge tabs as well as corner tabs con-nected to the bottom halves are folded into an upright position, overlapped and joined together by glueing or other means.
5. Process according to any one of claims 1, 2 and 3, wherein following the placement of a partly folded package onto two rows of objects first the side walls are gradually folded from an approximately horizontal initial position to an increasingly inclined position and finally to a vertical position.
6. Process according to any one of claims 1, 2 and 3, wherein the initially upright or slightly divergent rows of objects are spread into the package, against the direction of movement of the side walls until they contact the side walls as wall as the bottom halves, and these bottom halves are then brought together, as the rows of objects are moved to the upright position.
7. Process according to claim 1, wherein with the rows of objects upright the folding of the edge tabs connected to the bottom halves upwards and between the spread rows of objects resting on the bottom halves is continued until the edge tabs contact the inside of the rows of objects.
8. Process according to claim 7, wherein straps prepunched in the edge tabs are folded, before the folding of the edge tabs, into a position perpendicular to these edge tabs to form cross-stiffeners, and are inserted between the individual objects by the folding of the edge tabs as well as by the closing movement of the rows of objects.
9. Process according to any one of claims 1, 2 and 3, wherein the cross-sectional inside dimensions of the package, i.e. the inside width of the top wall as well as the inside height of the side walls, are slightly smaller than the outside dimensions of the objects, so that the package is wrapped around the objects under tension.
