Description
Sposób wyrobu detych celuloidowych raczek do parasoli i lasek wedlug wynalaz¬ ku niniejszego polega na tern, ze wytlacza¬ nie uzywanej zwykle gladkiej rurki celuloi¬ dowej w odpowiedniej formie odbywa sie nie zapomoca bezposredniego nadymania gazem, a zapomoca wsypania do rurki pew¬ nej ilosci weglanu amonu (np. 5 — 10 g) i umieszczenia tej rurki w przygotowanej do¬ wolnie rzezbionej formie metalowej, skla¬ dajacej sie z dwóch czesci. Zamknieta for¬ me z rurka wewnatrz sciska sie pod prasa i wstawia wraz z nia do gotujacej sie wody.Pod wplywem ciepla weglan, znajdujacy sie w rurce, wytwarza gazy, które rozdyma- ja rozmiekla rurke i, rozszerzajac jej scian¬ ki, wpychaja je do wglebien w sciankach formy. Po pewnym czasie, np. po 20 minu¬ tach wyjmuje sie prase wraz z forma z go¬ racej wody i chlodzi, wskutek czego raczka twardnieje i daje sie wyjac z formy. PLThe method of manufacturing specific celluloid handles for umbrellas and walking sticks according to the present invention is based on the fact that the extruding of the normally used smooth celluloid tube in a suitable form takes place not by directly inflating with gas, but by pouring a certain amount of carbonate into the tube. of ammonium (eg 5-10 g) and placing the tube in a prepared, freely carved metal form, consisting of two parts. A closed form with a tube inside is pressed under the press and puts with it into the boiling water. Under the influence of the heat, the carbon contained in the tube produces gases that expand the tube and, expanding its walls, push it to the cavities in the walls of the mold After some time, for example after 20 minutes, the press and the mold are removed from hot water and cooled, as a result of which the handle hardens and can be removed from the mold.
