FIELD: construction. ^ SUBSTANCE: device comprises a base, having opposite ends, an actuator mechanism hingedly installed on the base, and the first and second driving rolls displaced from each other in direction towards the base ends. The first and second rolls comprises a roll on the base and two rolls on the actuator mechanism designed for engagement of a wire, pulling between them, displacement relative to the base in direction between its ends and rotation of the wire. The actuator mechanism selectively moves the first and second rolls relative to each other. In another version of the device realisation the actuator mechanism consists of two elements and has a support on the base from displacement between the first and second positions. At the same time single rolls displaced from each other to the ends of the base are installed on the base and in the actuator mechanism. The manually controlled device for cable feed, as opposed to the first versions of realisation has a facility to connect one of the foundation ends to the guide pipe. ^ EFFECT: simplified operation. ^ 41 cl, 16 dwg |
