Abstract

This invention relates to a method for producing a plastic work piece to a spiral shaped vacuum cleaner hose. The work piece is produced by means of an extrusion method through a nozzle opening shaped as a continuous slot having at least two aligned, mainly flat parts (26, 27) that are separated by means of a, from the flat parts extending, mainly U-shaped first part (28). One of the flat parts (26) is connected to a second mainly U-shaped part (29) whereas the second flat part (27) is connected to a flange shaped portion (21) extending from the second flat part and intended to be joint to the second U-shaped part (29). The work piece is after extrusion mainly stretched to its final shape between the nozzle (11) and a guide (15) that is dimensioned such that its shape mainly corresponds to the final work piece the dimensions of the final work piece being considerably less than the dimensions of the nozzle opening. The work piece is in connection to the guide cooled by means of a liquid (14) the nozzle being directed such that the work piece during extrusion leaves the nozzle (11) at an angle with respect to the liquid surface. The invention also relates to a device for manufacturing said hose and a hose produced according to the method.

Description

514 968 2 Ett utföringsexempel av uppfinningen kommer nu att beskrivas med hänvisning till bifogad ritning på vilken fig 1 schematískt visar en anordning för att framstäla slangen under det att fig 2 visar en del av ett längsgående snitt genom slangen. An embodiment of the invention will now be described with reference to the accompanying drawing, in which Fig. 1 schematically shows a device for manufacturing the hose, while Fig. 2 shows a part of a longitudinal section through the hose.

Den i fig 1 visade anordningen innefattar en strångsprutmaskin 10 för plast med ett munstycke 11 som har en utträdesöppning för ett ämne 12 i form av en plaststräng varvid öppningen har en mot ämnet korresponderande form dock med den skillnaden att öppningen är överdimensionerat i förhållande till det färdiga ämnet. Munstycket 11 är så anordnat att den ur öppningen utträdande plaststrängen är riktad snett nedåt mot en behållare 13 med kylvåtska 14, företrädesvis vatten, i vilket plassträngen kyles och därmed stabiliseras. I närheten av vätskeytan är en styrning 15 anordnad varvid denna styrning består av en eller flera profilerade rullar som motsvarar det färdiga ämnets form. I behållaren liksom ovanför denna finns ett antal brytrullar 16 över vilka ämnet löper till en torkanläggning 17 där vätskan bringas att avgå från ämnet. Ämnet löper via ytterligare brytrullar 18 till en sträckrulle 19 som åstadkommer en sträckning av ämnet mellan munstycket ll och styrningen 15. Från sträckrullen 19 förs ämnet ner på en cylinderformad eller konisk roterande dorn 20 varvid ämnets ena kantparti 21 (se fig 2) kommer att ansluta till det andra kantpartiet 22 på närliggande varv samtidigt som en limsträng 23 utmatas från ett rnunstycke 24 och appliceras mellan sagda kantpartier. Under ämnets spiralformade upplindning på dornen härdar limmet och förbinder anslutande varv med varandra samtidigt som den bildade slangen 25 matas åt höger i figuren upp på ett par medroterande rullar 26 varefter slangen 25 medelst en icke visad kapanordning kapas i lämpliga längder.The device shown in Fig. 1 comprises an extruder 10 for plastic with a nozzle 11 which has an outlet opening for a blank 12 in the form of a plastic string, the opening having a shape corresponding to the blank, however with the difference that the opening is oversized in relation to the finished the subject. The nozzle 11 is arranged so that the plastic string emerging from the opening is directed obliquely downwards towards a container 13 with coolant 14, preferably water, in which the plastic string is cooled and thus stabilized. In the vicinity of the liquid surface a guide 15 is arranged, this guide consisting of one or more profiled rollers which correspond to the shape of the finished blank. In the container as well as above this there are a number of breaking rollers 16 over which the blank runs to a drying plant 17 where the liquid is caused to leave the blank. The blank runs via further breaking rollers 18 to a stretching roller 19 which provides a stretching of the blank between the nozzle 11 and the guide 15. From the stretching roller 19 the blank is lowered onto a cylindrical or conically rotating mandrel 20 whereby one edge portion 21 of the blank (see Fig. 2) will connect to the second edge portion 22 at adjacent turns while an adhesive string 23 is discharged from a nozzle piece 24 and applied between said edge portions. During the helical winding of the blank on the mandrel, the adhesive hardens and connects connecting turns to each other while the formed hose 25 is fed to the right in the figure onto a pair of co-rotating rollers 26, after which the hose 25 is cut to suitable lengths by means of a cutting device (not shown).

Det i fig 2 visade bandformade ämnet 12 bestå av, i ett snitt sett, två i linje med varandra liggande plana partier 26 resp 27 som åtskiljs av ett i huvudsak U-format, utskjutande första parti 28 och som dels avgränsas av ett i huvudsak U-format, utskjutande andra parti 29 vars yttre fria ände bildar ovannämnda första kantparti 22 och dels av ovannämnda andra kantparti 21 som har formen av en fläns som utskjuter åt samma häll de U-formade partierna.The strip-shaped blank 12 shown in Fig. 2 consists of, in section, two planar portions 26 and 27 lying in line with each other, which are separated by a substantially U-shaped, projecting first portion 28 and which are partly delimited by a substantially U -formed, projecting second portion 29 whose outer free end forms the above-mentioned first edge portion 22 and partly of the above-mentioned second edge portion 21 having the shape of an fl end projecting the same U-shaped portions.

Det bandformade ämnets form korresponderar således med munstycksöppningens form men munstycksöppningen har avsevärt större dimensioner än det färdiga ämnet varvid ämnets sträckning åstadkommer denna dimensionsförändring där strängen är plastisk, dvs området mellan styrningen 15 och sagda öppning, genom att reglera sträckrullens 19 514 968 3 hastighet i förhållande till den utmatade strängens hastighet. Sträckningen och munstyckets lutning a i' förhållande till kylvätskans yta är därvid vald så att strängens utloppsriktning från munstycket sammanfaller med sprutriktningen dvs att strängen ej bryts åt något håll omedelbart efter uttrådet ur munstycket. Vinkeln a är större än 10° och uppgår företrädesvis till ca 20° under det att det färdiga ämnet har en bredd som ligger i intervallet 10-20 mm som och företrädesvis uppgår till ca 14 mm under det att de U-formade partiernas höjd ligger i intervallet 2-6 mm och företrädesvis uppgår till ca 3,9 mm.The shape of the strip-shaped blank thus corresponds to the shape of the nozzle opening, but the nozzle opening has considerably larger dimensions than the finished blank, the stretching of the blank causing this dimensional change where the string is plastic, ie the area between the guide 15 and said opening, by regulating the speed of the stretch roller 19 to the speed of the output string. The tension and the inclination a of the nozzle in relation to the surface of the coolant are then chosen so that the direction of outlet of the string from the nozzle coincides with the direction of spraying, ie that the string is not broken in any direction immediately after exiting the nozzle. The angle α is greater than 10 ° and preferably amounts to about 20 ° while the finished blank has a width which is in the range 10-20 mm which and preferably amounts to about 14 mm while the height of the U-shaped portions is in the range 2-6 mm and preferably amounts to about 3.9 mm.

Munstycksöppningen har såsom tidigare sagts en form som motsvarar det färdiga ämnet men har avsevärt större dimensioner dvs en bredd som uppgår till 18-25 mm, företrädesvis ca 21 mm, och en höjd på 5-8 mm, företrädesvis ca 6,5 mm för de U-formade partierna.As previously stated, the nozzle opening has a shape which corresponds to the finished blank but has considerably larger dimensions, ie a width of 18-25 mm, preferably about 21 mm, and a height of 5-8 mm, preferably about 6.5 mm for the U-shaped parts.

Kylvätskans temperatur är mindre än 20°C och ligger företrädesvis runt ca 18°C.The temperature of the coolant is less than 20 ° C and is preferably around about 18 ° C.

Föreliggande metod och anordning möjliggör således att man genom den ökade bredden på ämnet åstadkommer en halvering av framställningstiden. Det skall också sägas att den ovan omtalade U-formen i detta sammanhang ej skall tolkas strikt utan att det även är möjligt att använda närliggande former såsom V-form eller Q-form.The present method and device thus make it possible to halve the production time by the increased width of the blank. It should also be said that the U-shape mentioned above should not be interpreted strictly in this context, but that it is also possible to use adjacent shapes such as V-shape or Q-shape.
