(54) Fremgangsmåde til fremstilling af genstande med spidser eller bør« ster af termoplastisk formstdf.
Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af genstande med spidser eller børster af termoplastisk formstof ved strengpresning, ved hvilken en fra et pressemundstykke udtrædende streng, især en streng med stay-, rør- eller båndformede bærere, og et stort antal af i længderetningen forløbende ribber i endnu plastisk tilstand under spænding i længderetningen på tværs af udtrædelsesretningen indskæres fra en eller to sider og derefter ® afkøles, 5 Til forskellige formål, som f.eks. curlere eller lukker for rr zf klædningsstykker benyttes burreagtige hager. Ved curlere bevirker py%
Lj. disse hager en fastholdelse af hårene, således at curlerne ikke af sig selv ruller af.
^ De kunstige burreagtige hager blev hidtil fremstillet meget Q besværligt af stropper, som består af formstoftråde, hvilke ved basis indvæves i et tekstilb&nd eller indsmeltes i bånd af førmstpf, 2 U3440
Disse stropper skæres herefter op, således at der dannes disse hager. Denne arbejdsmåde er allerede meget dyr, og hertil kommer, at båndene bagefter må videreforarbejdes, f.eks. opvikles på en rørformet curler og befæstiges. Ved curlere er der endvidere den store ulempe, at vævet, eller formstofbåndet, som bærer hagerne, forhindrer luftens gennemgang. Derfor tørrer det opviklede hår meget langsomt. Især forhindrer det store fremstillingsopbud og dermed prisen den handelsmæssige udbredelse af sådanne curlere. De på kendt måde fremstillede hager har naturligvis den store ulempe, at hagerne kun udviser den halve stropbue. Derfor er sådanne hagers virkning også kun ufuldkommen, idet der ikke findes nogen rigtig hage, men derimod kun den halve stropbue. Ved curlernes anvendelse forekommer især den ulempe, at de skarpe afskæringssteder på disse hager skærer ind i hovedets hud.
Den foreliggende opfindelse har til opgave ved en fremgangsmåde af den indledningsvis nævnte art at forsyne spidserne eller børsterne på de fremstillede genstande med burreagtigt virkende hager.
Til løsning heraf ombøjes ifølge opfindelsen ribbernes yderste ender hageformet på tværs af deres længderetning og presses indsnæv-rende' udad· Fortrinsvis presses ifølge opfindelsen en streng, ved hvilken hver anden i længderetningen forløbende nabostreng ombøjes 1 enderne hageformet imod hinanden.
En fremgangsmåde ifølge opfindelsen til fremstilling af en curler beskrives nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser en strengpresses mundstykke og den krævede kniv, fig. 2 viser forstørret en del af den fra strengpressens mundstykke udtrædende rørformede streng med de i længderetning forløbende hageformet ombøjede ribber, fig. 3 viser overskårne ribber til børster med hager, fig.-4 viser i længdesnit et delstykke af en ifølge strengpresningsfremgangsmåden fremstillet curler.
Et mundstykke 1 på en ikke vist strengpresse har en rund åbning 2 til fremstilling af en rørformet bærer. Langs den runde åbning 2*s omkreds findes fordelt slidser 3, som udadtil er indsnævret til tynde"slidser k, som har en ombøjet ende 5·
Den fi*a strengpressen udtrædende streng, som er delvis vist på fig. 2, består af en rørformet bærer og i længderetningen forløbende ribber 3'» som har indsnævrede ender 4* og hager 5'· Ribberne 3' er to og to i enden ombøjet hageformet mod hinanden.
3 143440
En ved mundstykket l's yderside (fig· l) i en pile retning på tværs af strengens udtrædelsesretning omløbende kniv 9 skærer nu de endnu plastiske ribber 3' med de indsnævrede ombøjede ender 4·, 5' til børster 6 med hager 7 (se fig. 3)* som er noget indad ombøjet.
Kniven 9 når med æggen ikke helt til den rørformede bærers 2» basis, således at der bliver stående en rest af ribben 3’ tilbage. som udvides, for at bringe børsten 6 i længderetning på ønsket afstand.
Den rørformede streng 2· afskæres spiralformigt indefra ved hjælp af en kniv 10, således at der dannes (se fig. 4) et stort antal af åbninger 11 og en spiral 12, som gennemløber det samlede runde legeme og holder de tilbageblivende ribber 3» sammen.
