Opfindelsen angår en plantebeholdergruppe, der består af flere i øvre og i nedre ende åbne rør, der er fremstillet af papir, 5 hvor de ved siden af hinanden placerede rør er indbyrdes forbundet ved forbindende dele, til dannelse af en uafbrudt række, der efter et givet antal rør i rækken er blevet foldet skiftevis til venstre og højre for at danne med hinanden forbundne rækker, og rørene i de ved siden af hinanden liggende 10 rækker er klæbet sammen med et vandopløseligt klæbemiddel, der tillader, at rørene kan trækkes ud af gruppen i en uafbrudt række, hvorved der i de forbindende dele findes separeringslinier, som opdeler dem i to dele, hvilke separationslinier udgøres af en række af slidser afbrudt af uopskårne forbindel-15 sespartier, hvorved enden af slidsen eller slidserne i nævnte række strækker sig til de forbindende deles øvre og/eller nedre ende.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a plant container group consisting of several open and lower end open tubes made of paper 5, wherein the adjacent tubes are interconnected by connecting members to form a continuous row which after a given number of pipes in the row has been folded alternately left and right to form interconnected rows, and the pipes in the adjacent 10 rows are adhered together with a water-soluble adhesive which allows the pipes to be pulled out of the group in an uninterrupted row, whereby there are separating lines in the connecting parts which divide them into two parts, which separation lines are constituted by a series of slits interrupted by uncut joining portions, whereby the end of the slit or slots in said row extends to the connecting upper and / or lower ends.
I i forvejen kendt teknik indgår der en gruppe af plantebehol-20 dere fremstillet af papir, hvilke beholdere er forbundet med hinanden, som det vises i US patentskrift nr. 3.515.036. Når plantebeholdergruppen placeres på en automatisk omplantningsmaskine, og hver papirbeholderrække separeres til individuelle, med planter forsynede papirbeholdere, benyttes der menne- ' 25 skelig arbejdskraft eller også kræves en separeringsmekanisme med et skærende blad, hvorfor forbindelsesdelene i det sidstnævnte tilfælde altid ituskæres i en tilstand med trækbelastning, hvorved bladbrud kan forekomme, så ituskæringen bliver forhindret i lang tid. På grund heraf var de kendte frem-30 gangsmåder til separering af plantebeholdere under anvendelse af menneskelig arbejdskraft eller af det ituskærende blad så ufordelagtige, at kontinuerlige plantningsoperationer med de til en gruppe sammensatte, i papirbeholdere anbragte planter blev umulige, og man fik en ineffektiv drift.Prior art includes a group of plant containers made of paper, which containers are interconnected, as shown in U.S. Patent No. 3,515,036. When the plant container group is placed on an automatic transplanting machine and each paper container row is separated into individual planted paper containers, human labor is used or a cutting blade separation mechanism is also required, so in the latter case the connecting parts are always cut in a state of tensile load, whereby leaf rupture can occur, so that cutting is prevented for a long time. Because of this, the known methods for separating plant containers using human labor or the shredding leaf were so disadvantageous that continuous planting operations with the plants placed in a group of composite paper containers became impossible and ineffective operation was obtained. .

art.nature.
Disse beholdere er fremstillet af to lange bånd af et materiale, der er gjort modstandsdygtigt over for forrådnelse, for 5 eksempel imprægneret papir. Hvert af de to bånd er foldet skiftevis til højre og venstre på tværs af deres længderetning, og når båndene derefter anbringes ved siden af hinanden og sammenbindes, for eksempel med et klæbemiddel, vil der opstå rørformede beholdere med en kantet omkreds og to åbne mod-10 stående ender, hvilke beholdere strækker sig i en fortløbende række, hvor der mellem de enkelte beholdere findes en forbindende del, som er sammensat af de to bånd. Hver gang der findes et forud fastsat antal beholdere i rækken, bøjes det følgende antal beholdere tilbage til anlæg langs siden af den 15 forudgående række, idet beholdernes og de forbindende deles dimension og tværsnit henholdsvis bredde fortrinsvis er afpasset på en sådan måde, at hver beholder i en række griber ind i mellemrummet mellem to beholdere i den tilstødende række, så beholderne alle ligger tæt sammen. På denne måde er der opbyg-20 get en af flere rækker af beholdere sammensat gruppe, hvorfra man ved træk i en beholder, som enten var den første eller sidste beholder i den fortløbende række og nu befinder sig i et hjørne af gruppen, kan udtrække beholderne påny til gendannelse af den lange fortløbende række, idet man ved dette træk 25 ophæver en eventuel binding, der for eksempel er frembragt ved klæbning, mellem mod hinanden liggende rækker.These containers are made of two long strips of a material resistant to decay, for example impregnated paper. Each of the two belts is folded alternately to the right and left transversely of their longitudinal direction, and when the belts are then placed side by side and bonded, for example, with an adhesive, tubular containers having an angular circumference and two open counterparts will form. 10 standing ends, which containers extend in a continuous row, where there is between the individual containers a connecting part composed of the two bands. Each time a predetermined number of containers are found in the row, the following number of containers is bent back to abutment along the side of the preceding row, the dimensions and cross-sections, respectively, of the containers and the width and width respectively being preferably adapted in such a way that each container in a row, the spaces between two containers in the adjacent row intervene so that the containers are all close together. In this way, one of several rows of container assemblies is constructed, from which, by drawing in a container, which was either the first or last container in the consecutive row and now located in one corner of the group, one can extract retaining the containers for restoration of the long continuous row, abolishing by this feature 25 any bonding produced, for example, by adhesive, between adjacent rows.
X takt med denne udtrækning kan beholderne aftages eller separeres enkeltvis fra den fortløbende række, idet de forbindende 30 dele overskæres eller overrives på langs, det vil sige efter en linie parallel med beholdernes længdeakse. For at fremme denne overskæring eller overrivning er det kendt at frembringe en separationslinie i hver af de forbindende dele i form af slidser afbrudt af uopskårne forbindelsespartier.X with this pull-out, the containers can be removed or separated individually from the consecutive row, the connecting parts being cut or longitudinally cut, that is, along a line parallel to the longitudinal axis of the containers. To promote this cutting or tearing, it is known to provide a separation line in each of the connecting parts in the form of slits interrupted by uncut connecting portions.
35 I den samlede gruppe kan der fyldes jord eller en egnet næringssubstans i beholderne, så der kan anbringes kimplanter i 3 DK 1 o t/b o b beholderne.35 In the total group, soil or a suitable nutrient can be filled into the containers so that seedlings can be placed in the containers.
Det er formålet med opfindelsen at angive en plantebeholder-gruppe, hvormed de ovennævnte ulemper ved den kendte teknik 5 kan overvindes og overrivningen foretages sikkert og med meget lille trækkraft.It is an object of the invention to provide a plant container group by which the above-mentioned disadvantages of the prior art 5 can be overcome and the tearing is carried out safely and with very little traction.
Dette formål opnås med en plantebeholdergruppe af den indledningsvist angivne art, hvilken plantebeholdergruppe ifølge op- j 10 findelsen er særegen ved, at den øverste og/eller nederste af slidserne strækker sig til de forbindende partiers øvre og/eller nedre ende og danner en separeringsstyredel eller -dele, hvorved den totale længde af separeringsstyredelen eller -delene er ca. 20-70% af de forbindende deles højde, og den tota-15 le længde af de uopskårne forbindelsespartier er 30-80% af de forbindende deles højde.This object is achieved with a plant container group of the type initially mentioned, which plant container group according to the invention is peculiar in that the upper and / or lower of the slots extend to the upper and / or lower end of the connecting parts and form a separating guide member or parts, whereby the total length of the separation guide part (s) is approx. 20-70% of the height of the connecting parts and the total length of the uncut connecting portions is 30-80% of the height of the connecting parts.
Opfindelsen er et resultat af studier af konstruktioner af de beskrevne kendte papirbeholdere og fremgangsmåder til enkelt-20 vis separation af sammenhængende papirbeholdere samt studier af udplantningsmaskiner til brug ved udøvelse af disse separationsfremgangsmåder. IThe invention results from studies of designs of the disclosed known paper containers and methods for single separation of contiguous paper containers as well as studies of planting machines for use in the practice of these separation methods.

Forskellige forsøg udførtes for at finde ud af, hvordan disse forbindende dele skulle itudeles rationelt, og herved opdages det, at i tilfælde med en gruppe, hvor de enkelte papirbeholdere i en række var forbundet med forbindende dele, som havde separeringslini-30 er, der var anvist med nålehuller, der var tilvejebragt ved hjælp af en symaskine, i lodret retning, det vil sige i en retning parallelt med papirbeholdernes længdeakse, eller med slidser, der var tilvejebragt med visse intervaller, kunne disse forbindende dele i betragtelig udstrækning modstå sepa- ! j 35 ration ved paralleltrækning i den vandrette retning, det vil sige i en retning vinkelret på papirbeholdernes længdeakse, ! medens disse kunne separeres ved hjælp af en lille kraft, hvis ίFirst, the construction of connecting parts in group 25 with interconnected paper containers was studied.

35 I tabel 1 er den vandrette trækstyrke (A) den maksimale be lastning ved tidspunktet for papirbeholdernes separation, hvor der i to beholdere, der var forbundne med hinanden, blev dre- 5 DK 15078bb vet planter frem under normale fremdrivningsbetingelser, og efter færdiggjort fremdrivning fjernedes planterne og erstattedes med heksagonale stænger fremstillet af aluminium og med en form, der svarede til papirbeholderhulheden, hvorved en af 5 papirbeholderne med en aluminiumsstang sattes fast og den tilstødende beholder via den i denne indstukne aluminiumstang udsattes for en vandret trækbelastning for at frembringe separationen på denne måde.35 In Table 1, the horizontal tensile strength (A) is the maximum load at the time of separation of the paper containers, where in two containers connected to each other plants were advanced under normal propulsion conditions and after completion of propulsion. the plants were removed and replaced with hexagonal rods made of aluminum and with a shape corresponding to the paper container cavity, whereby one of the 5 paper containers with an aluminum rod was attached and the adjacent container was subjected to a horizontal tensile load via the aluminum rod in this section. this way.
10 Trækstyrken (B) under tidsforløbet er den maksimale belastning i tiden for separationen af papirbeholderne, hvor den ene af papirbeholderne indeholdende en aluminiumstang sattes fast ifølge det ovenfor anførte, medens den anden udsattes for en trækkraft alene ved dennes øvre endeparti for derved at frem-15 bringe separering (under oprivningsforløbet danner de oprevne kanter i dette tilfælde et V). Når afstanden mellem slidserne (det vil sige længden af forbindelsespartierne) i de forbindende dele mellem papirbeholderne forandres på passende måde og forbindelsespartierne (ikke opskårne partier) ændres fra et 20 sted til et antal steder, forandres den vandrette trækstyrke ikke, medens trækstyrken under oprivningsforløbet bliver tydeligt mindre, og det fremgår, at selv når trækkraftens styrke er omkring 25% af den vandrette trækstyrke, kan papirbeholderne separeres tilfredsstillende. Der optræder en lille forskel, 25 når forbindelsespartierne mellem slidserne er mindre end 6 mm, hvorved det på den anden side gælder, at hvis forbindelsespartierne bliver for lange, kan trækstyrken blive større end itu-rivningsstyrken for papirbeholderne, og følgelig er 2-6 mm et optimum for forbindelsespartierne. Desuden har det vist sig, 30 at hvis det øverste parti af separationsliniens slids er i kontakt med den øvre kant af de forbindende dele mellem papirbeholderne, bliver separationen til hver individuel papirbeholder med plante virkelig god, når hele længden af forbindel- i sespartierne (ikke opskåret parti) i de forbindende dele mel-35 lem papirbeholderne er bestemt til 36 mm, og dette opdeles i seks forbindelsespartier, hvor hvert sådant parti har en læng- ! de på 6 mm, hvorved det bliver muligt at forandre fordelings- , DK 160786 3 6 mønstret på forskellige måder og således tillige trækstyrken ved separationfremgangsmåden, hvor oprivningspunktet bevæger sig under oprivningsforløbet. Trækkraftens styrke, som opnåedes ved vandret trækning, sammenlignedes og studeredes, hvor-5 ved de i tabel 2 viste resultater opnåedes. Som det fremgår af tabel 2 virker den slids, der er i kontakt med den øvre kant af de forbindende dele, åbenbart som et separationsstyrende parti, og længden af dette separationsstyrende parti er fortrinsvis 20-70% af højden af de forbindende dele selv i den 10 ideale tilstand, og i praksis skal denne størrelse fortrinsvis være 30-40%. Når papirbeholderne er forbundet med forbindende dele med den angivne konstruktion, bliver der for første gang mulighed for en let gennemførlig mekanisk separation ved et simpelt træk i en papirbeholder i forhold til den resterende 15 del af en række af papirbeholdere. Med udgangspunkt i de resultater og kundskaber, som er opnået ifølge tabellerne 1 og 2, har det nemlig vist sig, at i det tilfælde, hvor de enkelte papirbeholdere i en række i gruppen er sammenkoblet ved hjælp af forbindende dele med henblik på at tillade kontinuerlig ud-20 trækning derudfra samt er forsynet med slidser, af hvilke hver enkelt har en vis længde fra den øvre kant af de forbindende dele, der sammenbinder papirbeholderne, i lodret retning og inkluderer den øvre kant, for derved at frembringe separationsstyrende partier, samt slidserne desuden er anbragt med 25 jævne mellemrum og lineært for derved at anvise separationslinierne, hvorved oprivningspunktet under oprivningsforløbet kan bringes til at bevæge sig oppefra og nedefter, kan denne sammenhængende papirbeholdergruppe, der understøtter planter, itudeles af en meget lille trækkraft.The tensile strength (B) during the passage of time is the maximum load in time for the separation of the paper containers, in which one of the paper containers containing an aluminum rod is fixed according to the above, while the other is subjected to a tensile force only at its upper end portion, thereby producing 15 cause separation (during the tearing process, the torn edges in this case form a V). When the distance between the slots (that is, the length of the connecting portions) in the connecting portions between the paper containers is appropriately changed and the connecting portions (not cut portions) change from one location to a plurality of locations, the horizontal tensile strength does not change while the tensile strength during the tearing process becomes clearly smaller, and it can be seen that even when the tensile strength is about 25% of the horizontal tensile strength, the paper containers can be satisfactorily separated. A slight difference occurs when the connection portions between the slots are less than 6 mm, on the other hand, if the connection portions become too long, the tensile strength can be greater than the tear strength of the paper containers, and consequently is 2-6 mm. an optimum for the connecting portions. In addition, it has been found that if the top portion of the separation line slot is in contact with the upper edge of the connecting portions between the paper containers, the separation of each individual plant paper container becomes really good when the entire length of the connecting portions (not the cut portion) in the connecting portions between the paper containers is set at 36 mm, and this is divided into six connecting portions, each such portion having a longitudinal portion; those of 6 mm, which makes it possible to change the distribution pattern in different ways and thus also the tensile strength of the separation method, where the tearing point moves during the tearing process. The strength of traction obtained by horizontal drawing was compared and studied, whereby the results shown in Table 2 were obtained. As can be seen in Table 2, the slit in contact with the upper edge of the connecting parts evidently acts as a separation controlling portion, and the length of this separation controlling portion is preferably 20-70% of the height of the connecting parts even in the 10, and in practice this size should preferably be 30-40%. When the paper containers are connected to connecting parts of the specified construction, for the first time, a simple feasible mechanical separation is possible by a simple pull in a paper container relative to the remaining part of a series of paper containers. On the basis of the results and knowledge obtained according to Tables 1 and 2, it has been found that in the case where the individual paper containers in a row in the group are interconnected by means of connecting parts in order to allow continuous extending therefrom and provided with slots, each of which has a certain length from the upper edge of the connecting portions connecting the paper containers vertically and including the upper edge, thereby producing separation guiding portions, as well as the slots. in addition, arranged at regular intervals and linearly so as to indicate the separation lines whereby the tearing point during the tearing process can be moved upwards and downwards, this continuous paper container group supporting plants can be separated by a very small traction.

På tegningen vises der en sammensat gruppe P, der omfatter et antal papirbeholdere 1 fyldt med næringssubstans med deri an- 5 bragt kimplanter 7. Hver papirbeholder 1 er dannet af to ark i 2, som er fremstillet af et papirmateriale, såsom kraftpapir ; og så videre, samt sædvanligvis har en sådan bestandighed over |In the drawing, there is shown a composite group P comprising a plurality of paper containers 1 filled with nutrient substance with seedlings 5 therein.

for forrådnelse, at der ikke finder nogen forrådnelse sted un- i der fremdrivningen af planter. De hule papirbeholdere 1 har 10 heksagonalt tværsnit dannet ved en passende foldning af arkene 2. Forbindende dele 3 er anbragt til at sammenbinde individuelle papirbeholdere 1 indbyrdes og er sædvanligvis fremstillet ! af det samme materiale som papirbeholderne 1, men ethvert materiale, der kan tilvejebringe den samme virkning som den, der 15 er beskrevet ovenfor, kan anvendes til disse forbindende dele.for decomposition, that no decomposition occurs during the propulsion of plants. The hollow paper containers 1 have 10 hexagonal cross sections formed by a suitable folding of the sheets 2. Connecting parts 3 are arranged to bond individual paper containers 1 to one another and are usually made! of the same material as the paper containers 1, but any material which can provide the same effect as the one described above can be used for these connecting parts.
Til at tilvejebringe de forbindende dele mellem op til hinanden grænsende papirbeholdere 1, er arkene 2, der danner papirbeholderne, sammenklistrede med hinanden med jævne mellemrum, eller også kan de forbindende dele opnås i overensstemmelse 20 med indholdet af US patentskrift nr. 3.515.036 på den måde, at papirbeholderne først formes, og at visse breddepartier på arkene derefter belægges separat med klæbemiddel, hvorefter arkene sammenklistres til papirbeholdere, så arkene har et og | samme materiale helt igennem, men det er også muligt at be-25 nytte ark af forskellige materialer, og enhver egnet måde til tilvejebringe af ovennævnte resultat kan benyttes. En slids 4 står i kontakt med de forbindende deles 3 øvre kant 3’ og er j dannet vinkelret i forhold til denne øvre kant, hvorved denne slids 4 udgør et separationsstyrende parti til at gøre itude-30 lingen af de forbindende dele lettere. Slidser 5 er med visse intervaller anbragt på en linie under det separationsstyrende parti 4. Ikke opskårne forbindelsespartier 6 findes mellem slidserne 5, og en separationslinie 6' anvises således ved de efter hinanden følgende slidser 5 og forbindelsespartier 6.To provide the connecting parts between adjacent paper containers 1, the sheets forming the paper containers are periodically pasted together or the connecting parts can be obtained in accordance with the contents of U.S. Patent No. 3,515,036 to the way that the paper containers are first formed and that certain width portions of the sheets are then coated separately with adhesive, after which the sheets are glued to paper containers so that the sheets have one and | same material throughout, but it is also possible to utilize sheets of different materials and any suitable way of providing the above result can be used. A slot 4 is in contact with the upper edge 3 'of the connecting parts 3 and is formed perpendicular to this upper edge, this slot 4 forming a separation guiding portion to facilitate the disintegration of the connecting parts. Slots 5 are arranged at certain intervals on a line below the separation controlling portion 4. Uncut cut portions 6 are found between the slots 5, and a separation line 6 'is thus designated by the successive slots 5 and connecting portions 6.
35 Følgelig er en større del af de forbindende dele 3 skåret bort langs et lodret snit på den måde, at papirbeholderne er sam- | menbundet via forbindelsespartier 6, der lades blive tilbage. j \ 10 DK 160780 8 I forbindelse med den sammensatte papirbeholdergruppe ifølge opfindelsen bør det påpeges, at den totale længde af forbindelsespartierne og disses fordeling er meget væsentlige ting. For at tillade udtrækning i en række af sammensatte plantebe-5 holdere, der indgår i papirbeholdergruppen, efter plantefrem-drivningen, skal de forbindende dele have tilstrækkelig styrke hertil, medens disse forbindende dele skal kunne itudeles let uden nogen modstand i et efterfølgende itudelingstrin. Forbindende dele 3, der opfylder ovennævnte krav, har en konstruk-10 tion, der er beskrevet tidligere under henvisning til eksperimentelle eksempler, hvorved længden af det separationsstyrende parti 4 skal være inde i området 20-70% af højden H af de forbindende dele 3, selvom denne befinder i en ideal tilstand, og fortrinsvis inde i området 30-40% af denne højde H. Under det 15 separationsstyrende parti 4 er slidserne 5 og forbindelsespartierne 6 anbragt skiftevis langs en linie. I dette tilfælde er den totale længde af forbindelsespartierne 6 sådan, at denne længde ligger inde i et område på 30-80% af de forbindende deles 3 højde H, hvorved forbindelsespartierne 6 er passende 20 fordelt. Det separationsstyrende parti 4 kan være anbragt ved det øvre kantparti eller det nedre kantparti af de forbindende dele 3 svarende til en dertil beregnet separationsmekanisme, eller også kan dette parti 4 være anbragt ved både det øvre og det nedre parti, hvorved separationslinien 6' passende kan væ-25 re anbragt i overensstemmelse med arrangementet af det separationsstyrende parti 4.Accordingly, a greater portion of the connecting portions 3 are cut away along a vertical section in that the paper containers are assembled. but bound via connecting portions 6 which are left behind. In connection with the composite paper container group according to the invention, it should be pointed out that the total length of the connecting portions and their distribution are very important things. In order to permit extraction in a number of composite plant containers forming part of the paper container group after plant propagation, the connecting parts must be of sufficient strength thereto, while these connecting parts must be easily detachable without any resistance in a subsequent partitioning step. Connecting parts 3 meeting the above-mentioned requirements have a construction described previously with reference to experimental examples whereby the length of the separation controlling portion 4 should be within the range 20-70% of the height H of the connecting parts 3 although this is in an ideal condition, and preferably within the range of 30-40% of this height H. Below the 15 separating guide portion 4, the slots 5 and the connecting portions 6 are arranged alternately along a line. In this case, the total length of the connecting portions 6 is such that this length is within a range of 30-80% of the height H of the connecting parts 3, whereby the connecting portions 6 are suitably distributed. The separation guiding portion 4 may be disposed at the upper edge portion or lower edge portion of the connecting parts 3 corresponding to a separate separation mechanism, or this portion 4 may be disposed at both the upper and lower portions whereby the separation line 6 'may suitably be disposed. be arranged in accordance with the arrangement of the separation controlling portion 4.
Der henvises nu til fig. 3-4, der viser en separeringsmekanisme 8 indrettet til at kunne overrive de forbindende dele 3 30 langs separations linien 6'. På fig. 3 angiver henvisningsbetegnelserne 9 og 10 styrevalser, der er sat fast på aksler 9', henholdsvis 10', og som hver for sig er dækket med hvert sit elastiske legeme 11, eksempelvis en svamp på den pågældende omkreds. Valserne 9 og 10 er anbragt lige over for hinanden 35 med et mellemrum, der tillader valserne at klemme en papirbeholder 1 fast. Akslerne 9' og 10’ er koblet til en drivmekanisme for på denne måde at kunne modtage drivkraft. MedløbendeReferring now to FIG. 3-4, showing a separation mechanism 8 arranged to be able to tear the connecting parts 3 along the separation line 6 '. In FIG. 3, reference numerals 9 and 10 denote guide rollers secured to shafts 9 'and 10', respectively, each covered with its own elastic body 11, for example a sponge on the circumference concerned. The rollers 9 and 10 are arranged opposite each other 35 at a space that allows the rollers to clamp a paper container 1 firmly. The shafts 9 'and 10' are coupled to a drive mechanism in order to receive drive power in this way. Leading

Hen- i visningsbetegnelserne 15 og 16 angiver bånd, hvorved båndet 15 ! er strakt over valserne 9, 13 og båndet 16 over valserne 10, 5 14, hvorved disse bånd lober i retningen ifølge pilene, og de suden er der mellem båndene 15, 16 dannet en papirbeholder-fremføringsbane 17. Separeringsvalser 18 og 19 er fastgjort på aksler 18' henholdsvis 19' og er dækket med hvert sit elastiske legeme 11 af eksempelvis svampemateriale på de pågældende 10 omkredsoverflader, af hvilke hver enkelt har konisk form, hvorved den øvre ende har en større diameter og den nedre ende en mindre diameter. Separeringsvalserne 18, 19 er konstrueret således, at det mindre diameterparti på den pågældende separeringsvalse har en periferihastighed, der er større end bånde-15 nes 15, 16 lineære hastighed, hvorved separeringsvalserne er monteret lige over for hinanden på hver sin side af og ved udgangen af papirbeholderfremføringsbanen 17.rollers 13 and 14 are covered with each of their elastic bodies 11 on the periphery concerned in the same way as the guide rollers. The display designations 15 and 16 indicate bands, whereby the band 15! are stretched over rollers 9, 13 and belt 16 over rollers 10, 5 14, whereby these belts run in the direction of the arrows, and southwardly there is formed between paper belts 15, 16 a paper container feeding path 17. Separating rollers 18 and 19 are secured to shafts 18 'and 19', respectively, and are covered with each elastic body 11 of, for example, sponge material on the respective 10 circumferential surfaces, each of which has a conical shape, the upper end having a larger diameter and the lower end having a smaller diameter. The separating rollers 18, 19 are constructed such that the smaller diameter portion of the respective separating roller has a peripheral velocity greater than the linear speed of the 15, with the separating rollers being mounted opposite each other on each side of and at the exit of the paper container feed web 17.
Virkemåden af den i fig. 3-4 viste separeringsmekanisme er 20 følgende. Rækken af papirbeholdere 1 fødes frem på papirbeholderf remføringsbanen 17 ved hjælp af båndene 15, 16, der roterer med en konstant hastighed, hvorved den forreste papirbeholder la klemmes mellem separeringsvalserne 18 og 19 ved denne banes udgang, og desuden er separeringsvalserne i dette 25 tilfælde konstrueret på den måde, at disses periferihastighed er større end båndenes 15, 16 hastighed, og diameteren af den pågældende separeringsvalses øvre parti er større end diameteren af det pågældende nedre parti, hvorfor det pågældende øvre parti har en større periferihastighed end det pågældende nedre 30 parti, og følgelig itudeles de forbindende dele mellem to på ' hinanden følgende papirbeholdere progressivt under hvert sit | oprivningsforløb ved hjælp af separeringsvalserne 18, 19, hvorved de adskilte papirbeholdere la udplantes en og en ved hjælp af et passende udplantningsapparat, og når et udslip-35 ningsrør 20 er monteret under separeringsvalserne 18, 19, kan t papirbeholderne la plantes på marken under benyttelse af det naturlige fald, hvorved denne type af sammensatte, med planterThe mode of operation shown in FIG. 3-4, the separation mechanism shown is 20 as follows. The row of paper containers 1 is fed onto the paper container feeding path 17 by means of the bands 15, 16 rotating at a constant rate, thereby squeezing the front paper container 1a between the separating rollers 18 and 19 at the exit of this web, and in addition, the separating rollers are constructed in this 25 case. in that their circumferential velocity is greater than the velocity of the strips 15, 16 and the diameter of the upper portion of the separating roll in question is greater than the diameter of the lower portion concerned, so that the upper portion in question has a greater peripheral velocity than that of the lower portion 30, and, consequently, the connecting portions between two consecutive paper containers are progressively separated under each other tearing process by means of the separating rollers 18, 19, whereby the separate paper containers 1a are transplanted one by one by means of a suitable planting apparatus, and when a discharge pipe 20 is mounted under the separating rollers 18, 19, the paper containers 1a can be planted in the field during use. of the natural fall, by which this type of compound, with plants
