Description

Fremgangsmåte til fremstilling av flatebegrensede klebestoffbelegg. Process for the production of surface-limited adhesive coatings.

Fremstillingen av klebebånd, særlig The production of adhesive tape, in particular

plastre, foregår som oftest på den måten patches, usually takes place that way

at den kohesive klebemasse bringes med that the cohesive adhesive is brought along

eller uten oppløsningsmiddel på bærestof-fer etter den vanlige fremgangsmåte. or without solvent on carriers according to the usual method.

Det er kjent å påføre slike klebemasser It is known to apply such adhesives

slik at det i lengde- eller tverretningen so that in the longitudinal or transverse direction

oppstår striper eller felter med belagte streaks or areas of coating occur

eller ubelagte steder med ønsket mønster. or uncoated areas with the desired pattern.

Til fremstilling av plastere med uforholds-messig tykke klebemassepåføringer anvendes en profilert valse, hvorover stoff-banen ved en vanlig pålegningsanordning For the production of plasters with disproportionately thick adhesive applications, a profiled roller is used, over which the fabric web by a conventional application device

Videre har man i likhet med kopper-trykkmetoden anvendt profilerte valser til Furthermore, similar to the cup-printing method, profiled rollers have been used for

overføring av klebemassen på bærestoffet. transfer of the adhesive onto the carrier material.

Endelig kan også klebemassen bringes på Finally, the adhesive can also be applied

De sistnevnte fremgangsmåter har be-tydelige ulemper, da klebemassen på grunn The latter methods have significant disadvantages, because the adhesive mass

av dens sterke klebekraft, blir hengende på of its strong adhesive power, stays on

valsen og sjablonene. Da det anvendes the roller and the templates. When it is used

sjablonen og det fås ujevnt belegg. Derfor the template and an uneven coating is obtained. Therefore

er det ved sjablonbelegningen nødvendig med en stadig rengjøring av sjablonene. is constant cleaning of the stencils necessary during stencil coating.

Det ble nå funnet at de nevnte ulemper kan unngås og fremgangsmåten til å frem-stille flatebegrensede klebstoffbelegg kan vesentlig forenkles hvis klebemassen bringes på det luftgjennomtrengelige bærema-teriell under anvendelse av trykk og undertrykk. Til utøvelsen av denne fremgangsmåte anvendes en påføringssylinder som er bestemt til opptagelse av klebemassen som står under trykk og hvis mantel er gjennombrutt etter klebemassebeleggets ønskede mønster. Denne sylinder er koplet sammen med et sugebord og roterer med den samme omløpshastighet som sugebordets sugeanordning. Mellom sylinder og sugebord føres det luftgjennomtrengelige bærestoff gjennom. Trykket på klebemassen innstilles slik at det er tilstrekkelig til å overvinne friksjonen av klebemassen til uttredelsen av sylinderens åpninger, mens sugebordets undertrykk overfører klebemassen på bærematerialet og fester den der. Sugebordets virkning er størst når sylinderens åpninger står loddrett over sugebordet. It was now found that the aforementioned disadvantages can be avoided and the method for producing surface-limited adhesive coatings can be substantially simplified if the adhesive mass is applied to the air-permeable support material using pressure and vacuum. To carry out this method, an application cylinder is used which is intended for receiving the adhesive mass which is under pressure and whose jacket is pierced according to the desired pattern of the adhesive mass coating. This cylinder is connected to a suction table and rotates at the same rotational speed as the suction table's suction device. The air-permeable carrier material is passed between the cylinder and suction table. The pressure on the adhesive is set so that it is sufficient to overcome the friction of the adhesive to exit the cylinder's openings, while the suction table's negative pressure transfers the adhesive onto the carrier material and fixes it there. The suction table's effect is greatest when the cylinder's openings are vertical above the suction table.

Fremgangsmåten og anordningen for-klares i forbindelse med tegningen. Fig. 1 viser apparaturen skjematisk. Fig. 2 viser et snitt gjennom påførings-anordningen etter linjen A—B i fig. 1. Fig. 3 viser en modifisert utførelses-form. Fig. 4 viser en del av plaster forsynt The procedure and the device are explained in connection with the drawing. Fig. 1 shows the apparatus schematically. Fig. 2 shows a section through the application device along the line A—B in fig. 1. Fig. 3 shows a modified embodiment. Fig. 4 shows part of the plaster supplied

med et flatebegrenset belegg. with a surface-limited coating.

Klebemassen som befinner seg i be-holderen 3 blir ved hjelp av trykkluft pres-set gjennom rørledningen 8 inn i påleg-ningssylinderen 4. Derunder innstilles trykket fra trykkflasken 1 ved hjelp av venti-len 2, slik at det er tilstrekkelig til å overvinne friksjonen av klebemassen i tilled-ningen 8 og i gjennomboringene 7 til sylinderen 4. Sylinderen 4 og sugeanordnin-gen 9 til sugebordet 5 settes i rotasjon med vanlige drivanordninger. Ved hjelp av sugebordets undertrykk, som innvirker på bærestoffet 6 i området av åpningene 10, blir klebemassen suget fra sylinderen 4 over på bærestoffet 6. Sugevirkningen inntrer bare når gjennomboringene til pålegnings-sylinderen 4 står umiddelbart over sugean-ordningen 10 til sugebordet 5. The adhesive in the container 3 is pressed through the pipeline 8 into the application cylinder 4 with the help of compressed air. Underneath, the pressure from the pressure bottle 1 is adjusted using the valve 2, so that it is sufficient to overcome the friction of the adhesive in the lead 8 and in the through holes 7 of the cylinder 4. The cylinder 4 and the suction device 9 of the suction table 5 are set in rotation with normal drive devices. With the help of the suction table's negative pressure, which acts on the carrier material 6 in the area of the openings 10, the adhesive mass is sucked from the cylinder 4 onto the carrier material 6. The suction effect only occurs when the perforations of the application cylinder 4 are immediately above the suction device 10 of the suction table 5.

For å oppnå en større sugevirkning kan sugebordets overflate, som det ses av fig. 3, krummes svakt og sugeflaten 10 for-størres. To achieve a greater suction effect, the surface of the suction table, as can be seen from fig. 3, is slightly curved and the suction surface 10 is enlarged.

Pålegningstykkelsen av klebemassen på bærestoffet kan reguleres ved sugebordets undertrykk. Desto større undertrykket er, desto mere klebemasse overføres på bæreren. The application thickness of the adhesive compound on the carrier material can be regulated by the suction table's negative pressure. The greater the negative pressure, the more adhesive is transferred to the carrier.

lindre som kan utskiftes. Det kan altså med en belegningsanordning og flere sylindre fremstilles ønskede mønstre. relieve which can be replaced. Desired patterns can thus be produced with a coating device and several cylinders.

Gjennomboringene i pålegningssylin-deren kan anordnes slik at klebemassen på plasteret danner bestemte mønstre, orna-menter, tall eller bokstaver. The perforations in the application cylinder can be arranged so that the adhesive on the patch forms specific patterns, ornaments, numbers or letters.
