Abstract

A material to be used as an impact-absorbing, warming, flotation, padding, or similar material (1), comprising a plastic-based basic substance, particularly a cellular plastic, with holes to reduce its sweatiness or for other purposes. According to the invention, the holes (2) have at least one cut (3), to permit the hole/cut to be spread. The interior (2) of the holes, which has been cut away but has remained in place, can be easily detached by spreading the material, when the cutaway part will drop out by itself, or with the aid of a suitable mechanical operation, such as blowing with compressed air.

Description

, 113034, 113034

Muovimateriaali ja menetelmä sen tekemiseksi Tämä keksintö koskee muovimateriaalia ja menetelmää sen tekemiseksi. Erityi- i i 5 sesti muovimateriaali on solumuovia, esimerkiksi umpisolumuovia, josta tehdään \ \ erilaisia pehmusteita, iskun absorboijia tai kelluntamateriaaleja ja sen kaltaisia. \ !The present invention relates to a plastic material and a method for making it. In particular, the plastic material is a cellular plastic, for example a closed cell foam, which is made into various pads, shock absorbers or floating materials and the like. \!

Erityisesti edellä mainittuihin tarkoituksiin tarkoitettuja materiaaleja on pyritty teke- l mään hengittäviksi joko viillottamalla niitä, kuten tehdään suomalaisessa patentti- | 10 hakemuksessa 972210 tai reitittämällä niitä. Reikiä tehdään sopivin välimatkoin i tavanomaisesti säännöllisen kuvion mukaan sopivan paksuun levymäiseen mate riaaliin.In particular, materials intended for the above purposes have been made to be breathable, either by incision as in the Finnish patent application. 10 in application 972210 or by routing them. Holes are made at appropriate intervals, usually in a regular pattern, to a sheet material of suitable thickness.

Vakavana haittana rei’itetyn materiaalin valmistuksessa on se, että halutun reiän 15 vaatima rengasmainen leikkaus syntyy kyllä helposti monellakin eri tavalla, mutta reiän aukaiseminen poistamalla leikattu osa on hyvin hankalaa. Tämä johtuu luonnollisesti pitkälti materiaalista, joka on “kiinnipitävää” ja pyrkii pitämään irtileikatun materiaalipalan paikallaan. Tästä syystä reikien puhdistaminen auki on ollut jopa lähes käsityötä. On selvää, ettei nykyaikaisessa tuotannossa ole varaa 20 tehdä käsityötä, jos automatisoitu järjestelmä on mahdollinen.A serious disadvantage in the manufacture of perforated material is that the annular cut required by the desired hole 15 is easily obtained in many different ways, but opening the hole by removing the cut portion is very difficult. This is, of course, largely due to the material being "sticky" and tending to hold the piece of material cut off. For this reason, cleaning holes has even been almost manual. It is clear that modern production cannot afford to do manual work if an automated system is possible.

: Tämän keksinnön tarkoituksena on aikaansaada parannus sekä tuotteeseen että " :· myös sen valmistusmenetelmään. Niinpä keksinnön mukaisesti aikaansaadaan •: *: tuote, joka on entistä vähemmän hiostava ja myös rei’ityksen puhdistaminen on : .: 25 keksinnön mukaisella menetelmällä helppoa.: The object of the present invention is to provide an improvement both in the product and in the process of making it.

: · Edellä mainitut ja muut keksinnön hyvät puolet ja edut on aikaansaatu siten kuin esitetään tunnusomaiseksi oheisissa patenttivaatimuksissa.The foregoing and other advantages and advantages of the invention have been obtained as set forth in the appended claims.

30 Keksintöä kuvataan seuraavassa tarkemmin viittaamalla oheisiin piirustuksiin; joissa : Kuvio 1 esittää keksinnön mukaista materiaalia sen jälkeen, kun siihen on tehty • »« « : ; sopivat leikkaukset ja 2 113034The invention will now be described in more detail with reference to the accompanying drawings; in which: Figure 1 shows the material according to the invention after being subjected to • »« «:; suitable cuts and 2 113034

Kuvio 2 esittää samaa materiaalia tilassa, jossa irti leikattujen reikien sisustat poistetaan.Figure 2 shows the same material in a state where the core of the cut holes is removed.

Kuviot 1 ja 2 ovat itse itsensä selittäviä. Levymäiseen materiaaliin 1 on stanssattu 5 tai muuten tehty rengasmaisia leikkauksia, joiden sisusta 2 muodostaa sylinteri-mäisen kappaleen, joka tulisi poistaa reiän muodostamiseksi. Keksinnön mukaisesti poistamista avustamaan on tehty ainakin reiän 2 toiselle puolelle, mutta haluttaessa molemmille puolille viilto 3.Figures 1 and 2 are self explanatory. The plate material 1 is stamped 5 or otherwise made in the form of annular cuts whose interior 2 forms a cylindrical body which should be removed to form a hole. According to the invention, at least one side of the hole 2 has been made to assist in the removal but, if desired, a slit 3 on both sides.

10 Kuviossa 2 on esitetty, kuinka materiaalin 1 levittäminen sivuille päin aukaisee viillot 3, jolloin reiän sisus 2 jää vapaaseen tilaan ja on helppo poistaa siitä käyttämällä ravistelua tai esimerkiksi paineilmaa apuna. Sisus 2 saattaa levitysvai-heessa pudota pois ilman minkäänlaista mekaanista avustamista. Samoin se saattaa sähköisten ominaisuuksiensa takia jäädä kiinni levitetyn viillon 3 reunaan, 15 josta se kuitenkin helposti irtaantuu esimerkiksi paineilmaa käyttämällä.Figure 2 shows how spreading the material 1 sideways opens the slits 3, leaving the hole core 2 free and easy to remove using shaking or, for example, compressed air. The core 2 may fall off during the application step without any mechanical assistance. Likewise, due to its electrical properties, it may become trapped at the edge of the applied incision 3, from which it is easily detached, for example, by the use of compressed air.

On selvää, että edellä mainittua menetelmää ja materiaalia voidaan soveltaa moniin ei-jäykkiin perusmateriaaleihin, joilla esiintyy samankaltaisia ongelmia. Solumuovi lienee materiaaleista kuitenkin eräs eniten valmistetuista, joten sillä 20 alalla on tarve menetelmän ja tuotteen kehittelyyn suurin.It will be appreciated that the above method and material can be applied to many non-rigid base materials having similar problems. However, cellular plastic is probably one of the most manufactured materials, so there is the greatest need for method and product development in 20 industries.

: On selvää, että keksintöä voidaan muunnella monin tavoin. Esimerkiksi muodos- tettava reikä voi olla periaatteessa minkä muotoinen tahansa, ongelmat ovat sa-' mat. Jos menetelmää halutaan soveltaa koristeellisten reikien tekemiseen, se ; , ·; 25 toimii aivan yhtä hyvin kuin pyöreän reiän tapauksessa. Viillot 3 voivat olla tois- 1 ,· : puoleisia tai molemmin puoleisia ja niiden suunta voi olla muukin kuin materiaali- :.·’ : kappaleen pituussuunta. Jos suunta on poikittainen, venytys on tehtävä silloin pituussuunnassa. Vinot leikkaukset 3 toimivat esitetyllä tavalla ilman vaikeuksia.A: It is clear that the invention can be modified in many ways. For example, the hole to be formed can be of any shape, the problems are the same. If the method is to be used to make decorative holes, it; , ·; 25 works just as well as a round hole. The slits 3 may be one-sided, one-sided or two-sided and may have a direction other than material:. If the direction is transverse, then stretching must be done longitudinally. The oblique cuts 3 operate as shown without difficulty.
