Abstract
Un dispositivo di ritegno per il pezzo di punta del pattino che supporta il nastro abrasivo in una macchina rettificatrice del tipo a nastro. Il pezzo di punta è a forma di T presentando un organo trasversale dotato di porzioni laterali opposte ed uno stelo fra le porzioni laterali. La testa del pattino ha un recesso di ricezione dello stelo e spallamenti di posizionamento rivolti all'esterno su lati opposti del recesso. Il pezzo di punta è montato sulla testa con il suo stelo nel recesso e le sue porzioni laterali sovrastanti gli spallamenti. Il dispositivo di ritegno è un perno avente un gambo elastico dotato di una sporgenza che può essere o una porzione piegata lateralmente del gambo o una sporgenza a camma sul gambo. Il perno è ricevuto in aperture allineate nella testa e nello stelo. Quando fatta ruotare verso la posizione di bloccaggio. la sporgenza sul perno forza lo stelo in basso nel recesso e forza inoltre le porzioni laterali dell'organo trasversale in basso direttamente e in modo solidale sugli spallamenti.
