Device for bar material feeding

The invention relates to electrical engineering, in particular to the equipment for cast microwire production.The device for bar material feeding to the microwire casting installation contains a body, a drive roller, a pressure roller and a spring-loaded lever, joined with it. The rollers are made compound, at the same time each of them contains a hub (a), an external ring (c) and a ring of dielectric material (b), placed between them. Onto the lateral surface of the external ring (c) of the drive roller there is made an annular groove. Inventia se refera la electrotehnica, in particular la utilaj pentru producerea semiconductorului turnat.Dispozitivul de avans a materialului in bare la instalatia pentru turnarea semiconductorului contine o carcasa, o rola de antrenare, o rola de apasare si o parghie arcuita, legata cu ea. Rolele sunt executate compuse, totodata, fiecare din ele contine un butuc (a), un inel exterior (c) si un inel din material dielectric (b), amplasat intre ele. Pe suprafata laterala a inelului exterior (c) al rolei de antrenare este executat un canal inelar.
