Abstract

Un tampone in materiale flessibile ed elastico per lavorare a mano superfici con carta abrasiva presenta nel suo interno un passaggio di fluido collegato all'esterno mediante un manicotto di raccordo con un tubo flessibile comunicante con una sorgente di aspirazione o di alimentazione del fluido nonché con vari fori passanti distribuiti sulla superficie inferiore di lavorazione.Nel caso di aspirazione di aria sono previsti anche alcuni fori di sfiato verso l'esterno, di sezione minore rispetto a quelli di aspirazione vera e propria ed all'interno di detto passaggio, subito dopo l'immissione di detto raccordo con l'esterno, è formata una camera di bilanciamento della depressione.A pad in flexible and elastic material for working by hand on surfaces with abrasive paper has inside a passage of fluid connected to the outside by means of a coupling sleeve with a flexible hose communicating with a source of suction or fluid supply as well as with various through holes distributed on the lower machining surface. In the case of air intake, there are also some vent holes towards the outside, having a smaller section than the actual intake ones and inside said passage, immediately after the introduction of said connection with the outside, a depression balancing chamber is formed.
