Description
Przedmiotem wynalazku jest sposób wytwarza¬ nia elastycznych celuloidowych tasm sciernych, przeznaczonych do czyszczenia styków przerywa¬ cza delko w samochodach.Sposób wedlug wynalazku polega na wytworze¬ niu warstewki kleju na powierzchni tasmy celu¬ loidowej przez zanurzenie jej w rozpuszczalniku i nalozeniu na nia ziarna sciernego np. korundo¬ wego, które z kolei wgniata sie w glab tasmy przez walcowanie lub prasowanie.Jako rozpuszczalnik stosowac mozna absolutne alkohole metylowy, etylowy, butylowy same lub w mieszaninie z eterem, aldehydy, katony oraz estry.Przyklad. Paski celuloidowe zanurza sie w rozpuszczalniku na przeciag okolo 15 sekund, po czym obie powierzchnie tasmy obsypuje sie recznie lub mechanicznie ziarnem sciernym. Czesc ziarna przykleja sie, nadmiar zas opada. Tasme przepuszcza sie miedzy .dwoma walcami lub umieszcza na plycie metalowej i walkuje walkiem metalowym lub prasuje pod prasa. Ziarno scierne zostaje wgniecione wglab tasmy. Pozostala czesc rozpuszczalnika w tasmie odparowuje po kilku godzinach i tasma po pocieciu jej na paski odpo¬ wiedniej dlugosci jest gotowa do uzytku. PLThe subject of the invention is a method of producing flexible celluloid abrasive tapes intended for cleaning soft break contacts in cars. The method according to the invention consists in creating an adhesive film on the surface of a celluloid tape by dipping it in a solvent and applying abrasive grain on it. for example, corundum, which in turn is pressed into the depth of the tape by rolling or pressing. As a solvent, methyl, ethyl, butyl absolute alcohols can be used alone or in a mixture with ether, aldehydes, cathones and esters. The celluloid strips are immersed in the solvent for about 15 seconds, and then both surfaces of the strip are sprinkled manually or mechanically with abrasive grain. Part of the grain sticks, and the excess drops. The tape is passed between two rollers or placed on a metal plate and rolled with a metal roller or pressed under a press. Abrasive grain is indented into the tape. The remainder of the solvent in the tape evaporates after a few hours, and the tape, after being cut into strips of the appropriate length, is ready for use.
