Description

Opfindelsen vedrører et apparat til foldning af tøj, hvor tøjet, der ligger på en tilførselstransportør og skal foldes, ved hjælp af en indskydefolde-mekanisme og i afhængighed af mindst én kantføler 5 under foldning skydes gennem tilførselstransportørens transportplan, hvorhos indskydefoldemekanismen har mindst to, fortrinsvis styret drevne indskydefolde-valser, der hver har et organ til at trykke tøjet mod valserne under foldningen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for folding clothes, wherein the clothing lying on a supply conveyor and to be folded by a sliding folding mechanism and, depending on at least one edge sensor 5 during folding, is pushed through the conveying plane of the supply conveyor, the sliding folding mechanism having at least two, preferably controlled driven sliding rollers, each having a means for pressing the clothing against the rollers during folding.

10 Ved et kendt apparat til gennemførelse af ind skydefoldning (se tysk patentskrift 1 585 882) , består indskydefoldemekanismen af to med indbyrdes afstand anbragte og i afhængighed af et kantføleorgan drevne indskydefoldevalser, til hver af hvilke der hører en 15 trykvalse. Disse trykvalser er anbragt parallelt med indskydefoldevalserne og er styret bevægelige i lodret retning. Bevægelsen sker i retning mod arbejdsområdet udelukkende ved trykvalsernes egenvægt, medens de bliver løftet ved hjælp af en dertil beregnet ar-20 bejdscylinder.10 In a known apparatus for carrying out sliding folding (see German patent 1,558,882), the sliding folding mechanism consists of two spaced-apart spool rollers, each of which has a pressure roller, spaced apart. These pressure rollers are arranged parallel to the insertion rollers and are movable in a vertical direction. The movement takes place in the direction of the working area solely by the self-weight of the pressure rollers, while being lifted by means of a dedicated working cylinder.

Disse trykvalser har dog den ulempe, at bevægelsen i retning mod arbejdsområdet sker ved trykvalsernes egenvægt. Herved kommer de til anlæg mod tøjet, og da det er nødvendigt med friktionsforbindelse mel-25 lem indskydefoldevalserne og trykvalserne gennem tøjet, hvilken forbindelse tilvejebringes ved trykvalsernes egenvægt, må indskydefoldevalserne opfange de ved trykvalsernes fald opstående relativt store kræfter.However, these pressure rollers have the disadvantage that the movement in the direction towards the working area takes place at the weight of the pressure rollers. In this way, they come into contact with the clothing, and since friction connection is required between the insert rollers and the pressure rollers through the clothing, which is provided by the weight of the pressure rollers, the insert roll rollers must absorb the relatively large forces arising from the drop rollers.

For det andet er det væsentligt på meget kort tid at 30 bringe trykvalserne ud af deres arbejdsstilling, så at de kan bringes til anlæg mod det næste stykke tøj, der skal foldes. På grund af trykvalsernes relativt høje egenvægt er det nødvendigt med relativt store kræfter, navnlig i løftningens accelerationsfase.Secondly, it is essential in a very short time to bring the pressure rollers out of their working position so that they can be brought into contact with the next piece of clothing to be folded. Due to the relatively high self-weight of the pressure rollers, relatively large forces are needed, especially during the acceleration phase of the lifting.

Dette betinger tvangsmæssigt en tilsvarende kraftig konstruktion af motoren eller cylinderen til bevægelse af trykvalserne.This compulsively forces a correspondingly strong construction of the motor or cylinder to move the pressure rollers.

Endvidere er der ved tøj, der er forsynet 5 med sømme/ f.eks. sengebetræk, en væsentlig forskel i tykkelsen af tøjet, der skal foldes, så at den ved trykvalsernes egenvægt opnåede trykkraft ikke virker regelmæssigt på hele bredden af tøjet, der skal foldes , og dermed ikke regelmæssigt på indskydefolde-10 valserne. Herved bliver indtrækningen af tøjet i indskydefoldemekanismen uregelmæssig og foldningen dermed uregelmæssig, så at der sker en krydsforskydning af tøjet. Navnlig i tilfælde af tøj, der skal behandles på forskellig måde, f.eks. glat tøj, er der væsent-15 lig forskel på den måde materialet glider på over hele bredden, hvorved der kan optræde en krydsforskydning og dermed en foldning, der ikke er af korrekt kvalitet.Furthermore, in clothing provided with seams / e.g. bed cover, a significant difference in the thickness of the clothing to be folded so that the compressive force obtained by the pressure rollers' own weight does not act regularly on the entire width of the clothing to be folded, and thus not regularly on the insert folding rollers. In this way, the insertion of the clothing into the insert folding mechanism becomes irregular and the folding thus irregular, so that a cross-shifting of the clothing occurs. Especially in the case of clothes that need to be treated differently, e.g. smooth clothing, there is a significant difference in the way the material slides across the entire width, thereby causing a cross-shift and thus a folding which is not of the correct quality.

Med opfindelsen tilsigtes apparatet til fold-20 ning af tøj udformet således, at organerne til at trykke tøjet mod indskydefoldevalserne under foldeoperationen sikrer en høj nøjagtighed ved foldningen uden krydsforskydning. Med opfindelsen tilsigtes der endvidere opnået en acceleration og bevægelse af disse 25 organer inden for den kortest mulige tid, navnlig fra deres arbejdsstilling til deres udgangsstilling.The invention aims at the apparatus for folding clothes designed so that the means for pressing the clothes against the insert folding rollers during the folding operation ensure a high accuracy of folding without cross-shifting. The invention further aims to achieve acceleration and movement of these organs within the shortest possible time, in particular from their working position to their starting position.

Med opfindelsen tilsigtes der ved en relativt let konstruktion og ved hjælp af yderligere kræfter, der begunstiger løftningen, opnået en hurtig accelera-30 tion og dermed en bevægelse af trykorganerne fra arbejdsstilling til udgangsstilling på kortest mulig tid.The invention aims at achieving a rapid acceleration and thus a movement of the pressure means from the working position to the starting position in the shortest possible time, with a relatively light construction and by additional forces favoring the lifting.

Dette opnås ifølge opfindelsen ved, at organerne til at trykke tøjet, der skal foldes, mod indskydefoldevalserne under foldningen består af flere 146102 3 til hver af indskydefoldevalserne hørende, uafhængigt af hinanden frit drejelige trykruller, der er lejret uafhængigt af hinanden på arme, og som er styret bevægelige fra en udgangsstilling, hvor trykrullerne er i 5 afstand fra indskydefoldevalserne, til en arbejdsstilling, hvor trykrullerne ligger an mod nævnte valser, og fra denne til udgangsstillingen.This is achieved according to the invention in that the means for pressing the clothing to be folded against the insertion folding rollers during the folding consist of a plurality of each of the insertion rollers belonging to each other independently freely rotatable pressure rollers which are mounted independently of each other on arms and which are controlled movable from an initial position, where the pressure rollers are at a distance from the insertion rollers, to a working position where the pressure rollers abut against said rollers, and from this to the initial position.

I trykrullernes arbejdsstilling er disse i anlæg mod tøjet og trykker dette mod indskydefoldevalser-10 ne, medens trykrullerne i deres udgangsstilling er beliggende i en sådan afstand fra indskydefoldevalser-ne, at tøjet, der skal foldes, kan indføres mellem rullerne og valserne.In the working position of the pressure rollers, these are in contact with the clothing and push it against the sliding rollers, while the printing rollers in their initial position are located at such a distance from the sliding rollers that the clothes to be folded can be inserted between the rollers and the rollers.

Fordelene ved opfindelsen består navnlig i, 15 at hver trykrulle uafhængigt af forskellige tykkelser af tøjet ligger an mod dette i arbejdsstillingen.In particular, the advantages of the invention consist in the fact that each pressure roller, independently of different thicknesses of the clothing, abuts against it in the working position.

Herved opnås der en regelmæssig friktion over hele bredden af tøjet mellem indskydefoldevalserne og tøjet, som skal foldes, så at en skrå forskydning af 20 tøjet undgås, og en regelmæssig foldning opnås.Thereby, a regular friction is obtained over the entire width of the fabric between the insert rollers and the fabric to be folded so as to avoid a sloping displacement of the fabric and a regular folding is achieved.

De til hvert sæt trykruller hørende sæt arme er fortrinsvis lejret på hver sin fælles aksel.The sets of arms associated with each set of rollers are preferably mounted on each of their common shafts.

Armene har fortrinsvis fjedre, der er anbragt på akslerne, hvor den ene ende af fjedrene er forbun-25 det med armene, og den anden ende står kraftbundet i forbindelse med akslerne.The arms preferably have springs disposed on the shafts, where one end of the springs is connected to the arms and the other end is connected to the shafts by force.

Ved hjælp af fjedrene, der anvendes til forspænding af trykrullerne, sikres der en regelmæssig anlægsvirkning mellem tøjet og indskydefoldevalserne 30 og en hurtig acceleration af trykrullerne ved løftning af disse fra arbejdsstillingen til udgangsstillingen.By means of the springs used for prestressing the pressure rollers, a regular abutment effect is ensured between the clothing and the insert rollers 30 and a rapid acceleration of the pressure rollers by lifting them from the working position to the initial position.

Endvidere optager de over armene på trykrullerne virkende fjedre de ved forsinkelsen af de til betjening af trykrullerne virkende stangsystemer og trykrul-35 lerne selv opstående kræfter, så at lejerne såvel som indskydefoldevalserne selv skånes i vidt omfang.Furthermore, the springs acting over the arms of the pressure rollers absorb the forces which arise for operating the pressure rollers and the pressure rollers themselves, so that the bearings as well as the roll-in rollers themselves are extensively spared.

Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor fig. 1 skematisk viser et apparat ifølge opfindelsen til foldning af tøj, 5 fig. 2 skematisk apparatet til foldning af tøj set ovenfra, fig. 3 skematisk trykrullerne med deres betjeningselementer i arbejdsstilling, og fig. 4 skematisk lejringen af trykrullernes 10 arme på akslen.The invention will be explained in more detail below with reference to the drawing, in which fig. 1 schematically shows an apparatus according to the invention for folding clothes; FIG. 2 is a schematic top view of the apparatus for folding clothes; FIG. 3 schematically shows the pressure rollers with their operating elements in working position; and FIG. 4 shows schematically the bearing of the arms of the pressure rollers 10 on the shaft.

Som det fremgår af fig. 1 og 2, har apparatet til foldning en tilførselstransportør, der er anbragt i et stativ 1. Tilførselstransportøren, der består af to drevne valser 2 og 3 og flere medløbende 15 transportgjorde 4, har til opgave at transportere tøjet, der skal foldes, og som allerede kan være foldet en eller flere gange, til foldestationen.As shown in FIG. 1 and 2, the apparatus for folding has a supply conveyor arranged in a rack 1. The supply conveyor, consisting of two driven rollers 2 and 3 and several adjacent conveyor belts 4, has the task of transporting the clothing to be folded and which may already be folded one or more times, to the folding station.

De til foldning tjenende indskydefoldevalser 5 og 6 befinder sig umiddelbart under den øverste bane af 20 transportgjordene 4 og kan drives i afhængighed af aktivering af kantfølere 8, 9 og 10 og en kobler 28, idet driften af enhver af de to indskydefoldevalser 5 og 6 kan standses til opnåelse af foldning på midten.The folding insert folding rollers 5 and 6 are located immediately below the upper web of the conveyor belts 4 and can be operated depending on the activation of edge sensors 8, 9 and 10 and a coupler 28, the operation of each of the two insert folding rollers 5 and 6 stopped to achieve folding in the middle.

25 Til bedre gribning af tøjet ved hjælp af ind- skydefoldevalserne 5 og 6 hører der til hver af indskydefoldevalserne 5 og 6 flere trykruller 11 og 12. Disse befinder sig i udgangsstillingen over den øverste bane af tilførselstransportøren og i af-30 stand fra denne og svinges umiddelbart før begyndelsen af gennemførelsen af foldeoperationen ved aktivering af en arbejdscylinder 13 og ved hjælp af et tilhørende og i det efterfølgende beskrevne stangsy- 146102 5 stem ned på det på indskydefoldevalserne 5 og 6 liggende tøj7 der skal foldes, og dermed i arbejdsstillingen. Afstanden fra trykrullerne 11 og 12 til den øverste bane af tilførselstransportøren vælges så stor, 5 at ethvert stykke tøj af tilførselstransportøren kan transporteres ind i mellemrummet. Disse trykruller 11 og 12 indvirker linder foldeoperationen ved hjælp af en kraft, der udgår fra arbejdscylinderen 13, og som gennem et i det følgende beskrevne stangsystem overfø-10 res på trykrullerne 11 og 12, og en yderligere af til trykrullerne hørende torsionsfjedre 18 og 19 fremkaldt forspænding ind på tøjet, så at der fremkommer en høj friktion mellem tøjet og indskydefoldevalserne 5 og 6 over hele tøjets bredde og dermed en 15 sikker indtrækning af tøjet, der skal foldes, gennem indskydefoldevalserne 5 og 6. Desuden bevirker torsionsfjedrene 18 og 19 en formindskelse af de kræfter, der opstår, når trykrullerne 11 og 12 rammer indskydefoldevalserne 5 og 6, da torsionsfjed-20 rene 18 og 19 selv fanger og optager kræfter.25 For better gripping of the clothes by the insertion rollers 5 and 6, each of the insertion rollers 5 and 6 includes several pressure rollers 11 and 12. These are in the starting position over the upper web of the supply conveyor and at a distance from this and immediately prior to the commencement of the folding operation is pivoted by activating a working cylinder 13 and by means of a corresponding and subsequently described rod system 5 descends on the clothes7 to be folded on the sliding folding rollers 5 and 6, and thus in the working position. The distance from the pressure rollers 11 and 12 to the top path of the feed conveyor is chosen so large that any piece of clothing by the feed conveyor can be transported into the space. These pressure rollers 11 and 12 act to relieve the folding operation by means of a force exiting the working cylinder 13, which is transferred to the pressure rollers 11 and 12 through a bar system described in the following, and a further torsion springs 18 and 19 of the pressure rollers induced biasing on the garment so that a high friction between the garment and insertion rollers 5 and 6 is produced over the entire width of the garment and thus a secure retraction of the garment to be folded through the insertion rollers 5 and 6. In addition, the torsion springs 18 and 19 diminishing the forces that occur when the pressure rollers 11 and 12 strike the sliding rollers 5 and 6 as the torsion springs 18 and 19 themselves capture and absorb forces.

Over hele indtrækningsbredden for hver af indskydefoldevalserne 5 og 6 er der flere trykruller 11 og 12, idet hver trykrulle 11 og 12 er lejret frit drejelig på en særlig arm 14 og 15. De til 25 trykrullerne 11 hørende arme 14 befinder sig på en fælles aksel 17, medens de til trykrullerne 12 hørende arme 15 er lejret på en fælles aksel 16.Over the entire pull-in width of each of the sliding rollers 5 and 6, there are several pressure rollers 11 and 12, each pressure roller 11 and 12 being mounted freely rotatable on a particular arm 14 and 15. The arms 14 of the 25 pressure rollers 11 are on a common shaft 17, while the arms 15 of the pressure rollers 12 are mounted on a common shaft 16.

Akslen 16 er lejret i lejer 30 og 31 i stativet 1, medens akslen 17 er lejret i lejer 30 32 og 33. Armene 14 og 15 er svingbart anbragt inden for bestemte vinkler.The shaft 16 is mounted in bearings 30 and 31 of the frame 1, while the shaft 17 is mounted in bearings 30 32 and 33. The arms 14 and 15 are pivotally positioned within certain angles.

Som det fremgår af fig. 4, er der på akslen 16 for hver arm 15 lejesteder, der består af en indstillingsring 20, der kan fastgøres på akslen . 146102 6 16, og en holdering 34, der ligeledes kan fastgøres på akslen 16, for en torsionsfjeder 18, hvilke ringe er anbragt i afstand fra hinanden til optagelse af amen 15. På indstillingsringen 20 er der et 5 anslag 36, der griber ind under armen 15, og som således danner anlæg for armen 15 i trykrullen 12's udgangsstilling. Torsionsfjederen 18 indvirker på armen med en passende forspænding, der kan ændres og indstilles i størrelse, idet den i holderingen 34 10 værende skrue 39 løsnes, hvorefter holderingen 34 kan drejes på akslen 16 og derefter igen fikseres med skruen 39.As shown in FIG. 4, on the shaft 16, for each arm, there are 15 bearing locations consisting of an adjustable ring 20 which can be secured to the shaft. And a retainer 34, which may also be secured to shaft 16, for a torsion spring 18 spaced apart from each other for receiving the ame 15. On the adjusting ring 20 there is a 5 stop 36 engaging below arm 15, thus forming abutment for arm 15 in the starting position of the pressure roller 12. The torsion spring 18 acts on the arm with a suitable bias that can be resized and adjusted as the screw 39 of the retaining ring 34 10 is loosened, after which the retaining ring 34 can be turned on the shaft 16 and then fixed again with the screw 39.

I udgangsstillingen ligger armen 15 an mod anslaget, medens indstillingsringen 20 og 15 dermed anslaget 36 i arbejdsstillingen svinges bort, så at torsionsfjederen 18's forspænding over armen 15 virker ind på trykrullen 12 og dermed på tøjet, der ligger på indskydefoldevalsen 6. Ved en yderligere drejningsbevægelse af akslen 16 og 20 dermed en yderligere svingning af anslaget 36 ved hjælp af det i det følgende beskrevne stangsystem bliver den på armen 15 virkende kraft fra torsionsfjederen 18 yderligere forøget, så at trykrullen 12's anlægskraft forøges yderligere.In the initial position, the arm 15 abuts against the stop, while the adjusting rings 20 and 15 are thus pivoted away in the working position, so that the bias of the torsion spring 18 over the arm 15 impacts on the pressure roller 12 and thus on the clothing lying on the slider roll 6. By a further rotational movement of the shaft 16 and 20, thus a further oscillation of the stop 36 by means of the rod system described in the following, the force acting on the arm 15 from the torsion spring 18 is further increased, so that the compressive force of the pressure roller 12 is further increased.

25 Denne i begge de forudgående sætninger beskrevne funktion gælder for samtlige trykruller 12, også for de til indskydefoldevalsen 5 hørende trykruller 11. De herfor gældende henvisningstal er i fig. 4 anført i parentes.This function described in both the preceding sentences applies to all pressure rollers 12, also to the pressure rollers belonging to the slide-in roll 5. The reference numerals for this are in fig. 4 listed in parentheses.

30 Som allerede nævnt, og som det fremgår af fig.30 As already mentioned, and as shown in FIG.

3, hvor stangsystemet og trykrullerne 11 og 12 er vist i deres arbejdsstilling, sker bevægelsen af trykrullerne 11 og 12 til arbejdsstillingen eller fra denne til udgangsstillingen ved hjælp af en arbejds- 146102 7 cylinder 13, fortrinsvis en pneumatisk cylinder.3, in which the rod system and the pressure rollers 11 and 12 are shown in their working position, the movement of the pressure rollers 11 and 12 to the working position or from this to the starting position is effected by means of a working cylinder 13, preferably a pneumatic cylinder.

Stempelstangen 38 i den pneumatiske cylinder 13 indvirker på en dobbeltarmet vægtstang 22, hvis omdrejningspunkt 29 er fastgjort til stativet 1.The piston rod 38 of the pneumatic cylinder 13 acts on a double arm lever 22, the pivot point 29 of which is fixed to the frame 1.

5 På hver side af den dobbeltarmede vægtstang 22 er der en forbindelsesstang 23 og 24. Forbindelsesstangen 23 overfører stempelstangen 38's bevægelse gennem en arm 25 til akslen 17, medens forbindelsesstangen 24 overfører bevægelsen gennem ar-10 men 26 til akslen 16. På forbindelsesstangen 24 er der en anlægskurve 27, der først ved en forudbestemt stilling af stemplet og en dermed forbundet forudbestemt kraft, der gennem trykrullerne 11 og 12 indvirker på tøjet, der ligger på indskydefoldevalser-15 ne 5 og 6, indkobler driften af indskydefoldevalser-ne 5 og 6 ved hjælp af kobleren 28.5 On each side of the double arm bar 22 there is a connecting rod 23 and 24. The connecting rod 23 transmits the movement of the piston rod 38 through an arm 25 to the shaft 17, while the connecting rod 24 transmits the movement through the arm 10 to the shaft 16. On the connecting rod 24 a abutment curve 27 which, at a predetermined position of the piston and an associated predetermined force, acting through the pressure rollers 11 and 12 on the clothing lying on the insert folding rollers 15 and 5, engages the operation of the insert fold rollers 5 and 6 by means of the coupler 28.

I beskrivelsen af virkemåden af apparatet til foldning er navnlig i fig. 3 tøjet, valserne 2 og 3, transportgjordene 4 og stativet 1 udeladt af 20 hensyn til overskueligheden.In the description of the operation of the apparatus for folding, in particular in FIG. 3 the clothes, the rollers 2 and 3, the conveyor belts 4 and the stand 1 omitted for reasons of clarity.

Apparatet virker som følger. Ved samtidig be-betjening af følerne 8, 9 og 10 bliver tilførsels-transportøren og dermed transporten af tøjet til foldestationen standset. Samtidig tilføres der tryk-25 luft til arbejdscylinderen 13.The device works as follows. By simultaneously operating the sensors 8, 9 and 10, the supply conveyor and thus the transport of the clothing to the folding station is stopped. At the same time, compressed air is supplied to the working cylinder 13.

Gennem den dobbeltarmede vægtstang 22, der er lejret i omdrejningspunktet 29, overføres bevægelsen fra stemplet og dermed stempelstangen 38 i arbejdscylinderen 13 til den dobbeltarmede vægt-30 stang 22.Forbindelsesstangen 23 og den til forbindelsesstangen 23 hørende arm 25 overfører denne bevægelse til akslen 17, medens forbindelsesstangen 24 og armen 26 overfører bevægelsen til akslen 16. Herved omsættes arbejdscylinderen 13's 35 frem og tilbagegående bevægelse til en omdrejende bevægelse.Through the double-arm bar 22 housed at the pivot point 29, the movement from the piston and, consequently, the piston rod 38 in the working cylinder 13 is transferred to the double-arm bar 30 22. The connecting rod 23 and the connecting rod 23 transmit this movement to the shaft 17. while the connecting rod 24 and the arm 26 transmit the movement to the shaft 16. The working and reciprocating movement of the working cylinder 13 is then translated into a revolving motion.

146102 8146102 8

Med drejebevægelsen af akslerne 16 og 17 bliver de derpå lejrede arme 15 og 14 og dermed trykrullerne 12 og 11 overført til arbejdsstillingen.With the rotational movement of the shafts 16 and 17, the arms 15 and 14 thereupon and thus the pressure rollers 12 and 11 are transferred to the working position.

Så snart trykrullerne 12 og 11 befinder sig i arbejds-5 stillingen, dvs. at de ligger an mod tøjet, der skal foldes, bliver torsionsfjedrenes forspænding virksom betinget af den stedfundne drejebevægelse af akslerne 16 og 17 og den dermed yderligere forbundne svingning af anslagene 36 og 37. Ved den yderligere drejnings-10 bevægelse af akslerne 16 og 17 forøges spændingen af torsionsfjedrene 18 og 19, så at anlægskraften for trykrullerne 12 og 11 forøges yderligere.As soon as the pressure rollers 12 and 11 are in the working position, ie. that they are in contact with the clothing to be folded, the bias of the torsion springs is effectively conditioned by the rotational movement of the shafts 16 and 17 and the further associated pivoting of the stops 36 and 37. By the further rotational movement of the shafts 16 and 17, the tension of the torsion springs 18 and 19, so that the contact force of the pressure rollers 12 and 11 is further increased.

Da armene 15 og 14 nu kan bevæge sig frit på akslerne 16 og 17, tilpasser de enkelte trykruller 15 12 og 11 sig til de i tøjet forekommende forskellige tykkelser. Herved udøver trykrullerne ensartet anlægstryk for tøjet over hele bredden af indskydefoldeval-serne 5 og 6.Since the arms 15 and 14 can now move freely on the shafts 16 and 17, the individual pressure rollers 15 12 and 11 adapt to the different thicknesses present in the clothing. In this way, the pressure rollers apply uniform abutment pressure to the clothing over the entire width of the insert rollers 5 and 6.

Efter at forbindelsesstangen 24 har gennem-20 løbet en bestemt vejlængde, og trykrullerne 11 og 12 dermed har indvirket med en forudbestemt kraft på tøjet, aktiverer den på forbindelsesstangen 24 værende anlægskurve 27 kobleren 28. Herved tilkobles driften af indskydefoldevalserne 5 og 6, og tø-25 jet trækkes dermed ind mellem indskydefoldevalserne og foldes.After the connecting rod 24 has passed a certain path length, and the pressure rollers 11 and 12 thus act with a predetermined force on the clothes, the abutment curve 27 of the connecting rod 24 activates the coupler 28. The operation of the insert folding rollers 5 and 6 is then activated and thawed. The -25 jet is thus retracted between the insertion rollers and folded.

Til opnåelse af foldning på midten kan indskydefoldevalserne 5 og 6 standses eller drives hver for sig i afhængighed af kantfølerne 8 og 10.To achieve folding in the middle, the sliding folding rollers 5 and 6 can be stopped or operated separately depending on the edge sensors 8 and 10.

30 Ved løftning af trykrullerne 11 og 12 og bevægelse af disse til deres udgangsstilling, hvilket sker ved en impuls, som opnås ved, at tøjet passerer til en bestemt stilling i foldeapparatet, sættes der lufttryk i modsat retning på arbejdscylinderen 35 13. Herved sættes akslerne 16 og 17 i modsat om-30 By lifting the pressure rollers 11 and 12 and moving them to their initial position, which is effected by an impulse obtained by the clothing passing to a certain position in the folding apparatus, air pressure is applied in the opposite direction to the working cylinder 35 13. Hereby the shafts are set. 16 and 17 to the contrary,
